I'm trying to submit a GET request from a web service and I want to pass a JSON argument as a parameter in the HTTP header. I have the following code that performs the get request without the JSON argument. How would I add the JSON argument in the HTTP body to pass the JSON parameter?
Heres is my code that works without the JSON argument:
-(void) getReposByDate:(void (^)(NSMutableArray *))handler
{
//Get credentials
NSDictionary *credentials = [KeychainUserPass load:#"APP NAME"];
NSString *userName = [credentials allKeys][0];
NSString *password = credentials[userName];
//Create request
NSString *requestString = #"SOME WEB SERVICE URL";
NSURL *url = [NSURL URLWithString:requestString];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
NSData *userPasswordData = [[NSString stringWithFormat:#"%#:%#", userName, password] dataUsingEncoding:NSUTF8StringEncoding];
NSString *base64EncodedCredential = [userPasswordData base64EncodedStringWithOptions:0];
NSString *authString = [NSString stringWithFormat:#"Basic %#", base64EncodedCredential];
NSURLSessionConfiguration *sessionConfig=[NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfig.HTTPAdditionalHeaders=#{#"Authorization":authString};
self.session=[NSURLSession sessionWithConfiguration:sessionConfig];
NSURLSessionDataTask *dataTask = [self.session dataTaskWithRequest:req completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSMutableDictionary *jsonObject = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSLog(#"%#", jsonObject);
handler([jsonObject valueForKeyPath:#"name"]);
}];
[dataTask resume];
}

In this above code whenever i will pass the static url i am getting the response but when i add that using stringwithformat i am not getting the response it will pass the null value can anyone suggest me what is mistake i am doing in the above code

Thanks in advance
There is way to much code. The substringToIndex and substringFromIndex are wrong, should not be in the code.
Use the literal syntax for the dictionaries:
NSDictionary *jsonDict = #{#"jsonData":#{#"password":password, #"empId":userName}};
NSData* jsonData = [NSJSONSerialization dataWithJSONObject:jsonDict options:0 error:&error];
I want to parse REST API with JSON is there any Best Example or Tutorial so help me...... Like I want to post request like Login and Register and then parse Feed using REST API..... I am using below code to post request
NSString *email = #"*******";
NSString *password = #"******";
NSString *apikey = #"********";
NSString *loginURL = #"***************";
NSURL *url = [NSURL URLWithString:loginURL];
NSString *JSONString = [NSString stringWithFormat:#"{\"apikey\":\"%#\",\"email\":\"%#\",\"password\":\"%#\"}", apikey, email, password];
NSData *JSONBody = [JSONString dataUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *loginRequest = [[NSMutableURLRequest alloc] initWithURL:url];
loginRequest.HTTPMethod = #"POST";
loginRequest.HTTPBody = JSONBody;
NSOperationQueue *queue = [NSOperationQueue new];
[NSURLConnection sendAsynchronousRequest:loginRequest
queue:queue
completionHandler:^(NSURLResponse *response, NSData *data, NSError *error){
NSLog(#"resp:%#",response);
// Manage the response here.
}];
To parse the JSON response, you will need to implement
id obj = [NSJSONSerialization JSONObjectWithData:data];
in your completionHandler.
To get NSDictionary object from server response you may use :
NSDictionary *myDict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error: &error];
After that you can get objects and keys from myDict
The good tutorial you can find here http://www.raywenderlich.com/5492/
Try this
NSDictionary *sampledict = #{#"email":email,#"password":password,#"apikey":apikey};
NSData *dataJson = [NSJSONSerialization dataWithJSONObject:sampledict options:0 error:NULL];
NSMutableURLRequest *loginRequest = [[NSMutableURLRequest alloc] initWithURL:url];
loginRequest.HTTPMethod = #"POST";
loginRequest.HTTPBody = dataJson;
//add these lines
[loginRequest setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[loginRequest setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
//remaining is the same in your code
Most of the information here refers to the abandoned ASIHTTPREQUEST project so forgive me for asking again.
Effectively, I need to swipe a magnetic strip and send the track 2 data to a webservice that returns "enrolled" or "notenrolled" (depending on the status of the card...)
So my data comes in simply as
NSData *data = [notification object];
And then I need to pass this to a url to the order of
http://example.com/CardSwipe.cfc?method=isenrolled&track2=data
And then just receive a response string...
I've searched a ton and there seems to be some conflicting answers as to whether this should be accomplished simply with AFNetworking, RESTkit, or with the native NSURL/NSMutableURLRequest protocols.
The options for performing HTTP requests in Objective-C can be a little intimidating. One solution that has worked well for me is to use NSMutableURLRequest. An example (using ARC, so YMMV) is:
- (NSString *) getDataFrom:(NSString *)url{
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:#"GET"];
[request setURL:[NSURL URLWithString:url]];
NSError *error = nil;
NSHTTPURLResponse *responseCode = nil;
NSData *oResponseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&responseCode error:&error];
if([responseCode statusCode] != 200){
NSLog(#"Error getting %#, HTTP status code %i", url, [responseCode statusCode]);
return nil;
}
return [[NSString alloc] initWithData:oResponseData encoding:NSUTF8StringEncoding];
}
Update:
Your question's title, and tagging say POST, but your example URL would indicate a GET request. In the case of a GET request, the above example is sufficient. For a POST, you'd change it up as follows:
- (NSString *) getDataFrom:(NSString *)url withBody:(NSData *)body{
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:body];
[request setValue:[NSString stringWithFormat:#"%d", [body length]] forHTTPHeaderField:#"Content-Length"];
[request setURL:[NSURL URLWithString:url]];
/* the same as above from here out */
}
Update for iOS 9:
So, [NSURLConnection sendSynchronousRequest] is deprecated starting from iOS 9. Here's how to do a GET request using NSURLSession starting from iOS 9
GET Request
// making a GET request to /init
NSString *targetUrl = [NSString stringWithFormat:#"%#/init", baseUrl];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:#"GET"];
[request setURL:[NSURL URLWithString:targetUrl]];
[[[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:
^(NSData * _Nullable data,
NSURLResponse * _Nullable response,
NSError * _Nullable error) {
NSString *myString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"Data received: %#", myString);
}] resume];
POST Request
// making a POST request to /init
NSString *targetUrl = [NSString stringWithFormat:#"%#/init", baseUrl];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
//Make an NSDictionary that would be converted to an NSData object sent over as JSON with the request body
NSDictionary *tmp = [[NSDictionary alloc] initWithObjectsAndKeys:
#"basic_attribution", #"scenario_type",
nil];
NSError *error;
NSData *postData = [NSJSONSerialization dataWithJSONObject:tmp options:0 error:&error];
[request setHTTPBody:postData];
[request setHTTPMethod:#"POST"];
[request setURL:[NSURL URLWithString:targetUrl]];
[[[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:
^(NSData * _Nullable data,
NSURLResponse * _Nullable response,
NSError * _Nullable error) {
NSString *responseStr = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"Data received: %#", responseStr);
}] resume];
Tested 100% working
Only for Objective C
-(void)fetchData
{
NSURLSessionConfiguration *defaultSessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration:defaultSessionConfiguration];
// Setup the request with URL
NSURL *url = [NSURL URLWithString:#"https://test.orgorg.net/ios/getStory.php?"];
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];
// Convert POST string parameters to data using UTF8 Encoding
NSString *postParams = #"";
NSData *postData = [postParams dataUsingEncoding:NSUTF8StringEncoding];
// Convert POST string parameters to data using UTF8 Encoding
[urlRequest setHTTPMethod:#"POST"];
[urlRequest setHTTPBody:postData];
// Create dataTask
NSURLSessionDataTask *dataTask = [defaultSession dataTaskWithRequest:urlRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSDictionary *results = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
//JSON Parsing....
NSString *message = results[#"Message"];
BOOL status = results[#"Status"];
if (status){
// Here you go for data....
}else{
UIAlertController *alert = [UIAlertController alertControllerWithTitle:#"App"
message:message
preferredStyle:UIAlertControllerStyleAlert]; // 1
UIAlertAction *firstAction = [UIAlertAction actionWithTitle:#"Ok"
style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
NSLog(#"You pressed button one");
}]; // 2
[alert addAction:firstAction]; // 4
[self presentViewController:alert animated:YES completion:nil];
}
}];
// Fire the request
[dataTask resume];
}
For Objective c :
-(void)loadData:(NSString*)url{
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"https://jsonplaceholder.typicode.com/posts"]];
[request setHTTPMethod:#"GET"];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSMutableArray *jsonArray = (NSMutableArray *)[NSJSONSerialization JSONObjectWithData:data options:NSASCIIStringEncoding error:&error];
if([self.delegate respondsToSelector:#selector(loadingData:)]){
[self.delegate loadingData:jsonArray];
}
}] resume];
}
Swift 5.5:
// MARK: - Posts
func getPosts(endPath : String, completion: #escaping ([Post]) -> ()) {
let urlPath = Constants.Network.BASE_URL + endPath
guard let url = URL(string: urlPath) else {
print("Invalid URL")
return
}
var request = URLRequest(url: url)
request.httpMethod = Constants.Network.HTTPS_METHOD
URLSession.shared.dataTask(with: request) { data, response, error in
if let data = data {
if let decodedResponse = try? JSONDecoder().decode([Post].self, from: data) {
DispatchQueue.main.async {
completion(decodedResponse)
}
return
}
}
print("Fetch failed: \(error?.localizedDescription ?? "Unknown error")")
}.resume()
}
**Simply Call and get your JSON Data.**
-(void)getJSONData
{
NSURL *url = [NSURL URLWithString:#"http://itunes.apple.com/us/rss/topaudiobooks/limit=10/json"];
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *data = [session dataTaskWithURL:url completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
NSError *erro = nil;
if (data!=nil) {
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&erro ];
if (json.count > 0) {
for(int i = 0; i<10 ; i++){
[arr addObject:[[[json[#"feed"][#"entry"] objectAtIndex:i]valueForKeyPath:#"im:image"] objectAtIndex:0][#"label"]];
}
}
}
dispatch_sync(dispatch_get_main_queue(),^{
[table reloadData];
});
}];
[data resume];
}
I have a php webpage that requires a login (userid & password). I have the user enter the information into the app just fine.. but I need an example on how to do a POST request to a website. The apple example on the support site is rather complicated showing a picture upload.. mine should be simpler.. I just want to post 2 lines of text..
Anyone have any good examples?
Alex
This is what I recently used, and it worked fine for me:
NSString *post = #"key1=val1&key2=val2";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:#"http://www.nowhere.com/sendFormHere.php"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
Originally taken from http://deusty.blogspot.com/2006/11/sending-http-get-and-post-from-cocoa.html, but that blog does not seem to exist anymore.
From Apple's Official Website :
// In body data for the 'application/x-www-form-urlencoded' content type,
// form fields are separated by an ampersand. Note the absence of a
// leading ampersand.
NSString *bodyData = #"name=Jane+Doe&address=123+Main+St";
NSMutableURLRequest *postRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"https://www.apple.com"]];
// Set the request's content type to application/x-www-form-urlencoded
[postRequest setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
// Designate the request a POST request and specify its body data
[postRequest setHTTPMethod:#"POST"];
[postRequest setHTTPBody:[NSData dataWithBytes:[bodyData UTF8String] length:strlen([bodyData UTF8String])]];
// Initialize the NSURLConnection and proceed as described in
// Retrieving the Contents of a URL
From : code with chris
// Create the request.
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://google.com"]];
// Specify that it will be a POST request
request.HTTPMethod = #"POST";
// This is how we set header fields
[request setValue:#"application/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
// Convert your data and set your request's HTTPBody property
NSString *stringData = #"some data";
NSData *requestBodyData = [stringData dataUsingEncoding:NSUTF8StringEncoding];
request.HTTPBody = requestBodyData;
// Create url connection and fire request
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
ASIHTTPRequest makes network communication really easy
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request addPostValue:#"Ben" forKey:#"names"];
[request addPostValue:#"George" forKey:#"names"];
[request addFile:#"/Users/ben/Desktop/ben.jpg" forKey:#"photos"];
[request addData:imageData withFileName:#"george.jpg" andContentType:#"image/jpeg" forKey:#"photos"];

#"username": #"reallyrambody",
#"password": #"123456"
};
request.HTTPBody = [NSStringFromQueryParameters(bodyParameters) dataUsingEncoding:NSUTF8StringEncoding];
// Connection
NSURLConnection* connection = [NSURLConnection connectionWithRequest:request delegate:nil];
[connection start];

I am a beginner in iPhone apps and I still have an issue although I followed the above advices. It looks like POST variables are not received by my server - not sure if it comes from php or objective-c code ...
the objective-c part (coded following Chris' protocol methodo)
// Create the request.
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://example.php"]];
// Specify that it will be a POST request
request.HTTPMethod = #"POST";
// This is how we set header fields
[request setValue:#"application/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
// Convert your data and set your request's HTTPBody property
NSString *stringData = [NSString stringWithFormat:#"user_name=%#&password=%#", self.userNameField.text , self.passwordTextField.text];
NSData *requestBodyData = [stringData dataUsingEncoding:NSUTF8StringEncoding];
request.HTTPBody = requestBodyData;
// Create url connection and fire request
//NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
NSData *response = [NSURLConnection sendSynchronousRequest:request
returningResponse:nil error:nil];
NSLog(#"Response: %#",[[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]);
Below the php part :
if (isset($_POST['user_name'],$_POST['password']))
{
// Create connection
$con2=mysqli_connect($servername, $username, $password, $dbname);
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
else
{
// retrieve POST vars
$username = $_POST['user_name'];
$password = $_POST['password'];
$sql = "INSERT INTO myTable (user_name, password) VALUES ('$username', '$password')";
$retval = mysqli_query( $sql, $con2 );
if(! $retval )
{
die('Could not enter data: ' . mysql_error());
}
echo "Entered data successfully\n";
mysqli_close($con2);
}
}
else
{
echo "No data input in php";
}
I have been stuck the last days on this one.
NSMutableDictionary *contentDictionary = [[NSMutableDictionary alloc]init];
[contentDictionary setValue:#"name" forKey:#"email"];
[contentDictionary setValue:#"name" forKey:#"username"];
[contentDictionary setValue:#"name" forKey:#"password"];
[contentDictionary setValue:#"name" forKey:#"firstName"];
[contentDictionary setValue:#"name" forKey:#"lastName"];
NSData *data = [NSJSONSerialization dataWithJSONObject:contentDictionary options:NSJSONWritingPrettyPrinted error:nil];
NSString *jsonStr = [[NSString alloc] initWithData:data
encoding:NSUTF8StringEncoding];
NSLog(#"%#",jsonStr);
NSString *urlString = [NSString stringWithFormat:#"http://testgcride.com:8081/v1/users"];
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:[jsonStr dataUsingEncoding:NSUTF8StringEncoding]];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager.requestSerializer setAuthorizationHeaderFieldWithUsername:#"moinsam" password:#"cheese"];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request success:<block> failure:<block>];
Thanks a lot it worked , please note I did a typo in php as it should be mysqli_query( $con2, $sql )
Here i'm adding sample code for http post print response and parsing as JSON if possible, it will handle everything async so your GUI will be refreshing just fine and will not freeze at all - which is important to notice.
//POST DATA
NSString *theBody = [NSString stringWithFormat:#"parameter=%#",YOUR_VAR_HERE];
NSData *bodyData = [theBody dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
//URL CONFIG
NSString *serverURL = #"https://your-website-here.com";
NSString *downloadUrl = [NSString stringWithFormat:#"%#/your-friendly-url-here/json",serverURL];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString: downloadUrl]];
//POST DATA SETUP
[request setHTTPMethod:#"POST"];
[request setHTTPBody:bodyData];
//DEBUG MESSAGE
NSLog(#"Trying to call ws %#",downloadUrl);
//EXEC CALL
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue currentQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
if (error) {
NSLog(#"Download Error:%#",error.description);
}
if (data) {
//
// THIS CODE IS FOR PRINTING THE RESPONSE
//
NSString *returnString = [[NSString alloc] initWithData:data encoding: NSUTF8StringEncoding];
NSLog(#"Response:%#",returnString);
//PARSE JSON RESPONSE
NSDictionary *json_response = [NSJSONSerialization JSONObjectWithData:data
options:0
error:NULL];
if ( json_response ) {
if ( [json_response isKindOfClass:[NSDictionary class]] ) {
// do dictionary things
for ( NSString *key in [json_response allKeys] ) {
NSLog(#"%#: %#", key, json_response[key]);
}
}
else if ( [json_response isKindOfClass:[NSArray class]] ) {
NSLog(#"%#",json_response);
}
}
else {
NSLog(#"Error serializing JSON: %#", error);
NSLog(#"RAW RESPONSE: %#",data);
NSString *returnString2 = [[NSString alloc] initWithData:data encoding: NSUTF8StringEncoding];
NSLog(#"Response:%#",returnString2);
}
}
}];
Hope this helps!
