Hello everyone I m trying to send two json objects in one request.
Here is what I did so far:
NSDictionary *credentials = [request getCredentials];
NSURL *url = [NSURL URLWithString:#"https://myurl.com"];
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:config];
NSMutableURLRequest *req = [[NSMutableURLRequest alloc] initWithURL:url];
req.HTTPMethod = #"POST";
[req setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[req setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
NSError *error = nil;
NSData *o = [NSJSONSerialization dataWithJSONObject:output
options:NSJSONWritingPrettyPrinted error:&error];
NSData *c = [NSJSONSerialization dataWithJSONObject:credentials
options:NSJSONWritingPrettyPrinted error:&error];
NSString *myString = [[NSString alloc] initWithData:o encoding:NSUTF8StringEncoding];
NSLog(#"DATA: %#",myString);
if (!error) {
NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:req
fromData:c completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
NSLog(#"RESPONSE %#", response);
}];
[uploadTask resume];
}
In this code I send only "NSData *c" but also I want to send "NSData *o" in the same request. Is it possible, I need your helps. Thanks.
you can combine dictonaries into one using below code then post to server.
#property (nonatomic, strong) NSMutableDictionary *configuration;
...
-(NSMutableDictionary*) configuration{
if (!_configuration) {
NSDictionary *core_config = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"installation" ofType:#"plist"]];
NSDictionary *app_config = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle bundleWithPath:#"/path/to"] pathForResource:#"something/data" ofType:#"plist"]];
[_configuration addEntriesFromDictionary: core_config];
[_configuration addEntriesFromDictionary: app_config];
NSLog(#"merged: %lu, core: %lu, app: %lu", (unsigned long)[_configuration count], (unsigned long)[core_config count], (unsigned long)[app_config count]);
// merged: 0, core: 4, app: 5
}
return _configuration;

I am new to JSON and I am trying to send a post I am wondering if how can I check if I did it properly or check the return value of it. Here's what I've done
NSURL *url = [NSURL URLWithString:#"http://json.myurl.com/.....];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
NSDictionary *tmp = [[NSDictionary alloc] initWithObjectsAndKeys:
#"email", #"Email",
#"password", #"FirstName",
nil];
NSError *error;
NSData *postdata = [NSJSONSerialization dataWithJSONObject:tmp options:0 error:&error];
[request setHTTPBody:postdata];
For a beginner, I would recommend using third party framework, widely used by iOS developers across the world, called AFNetworking.
By using AFNetworking, HTTP requests are simple as that:
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[manager POST:url parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
// TODO: Parse success here!
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
// TODO: Parse failure here!
}];
In given example, object responseObject is a representation of API response JSON object.
Installation and further usage instructions of AFNetworking can be found in their website.
To check JSON POST return value:
NSString *strUrl=[NSString stringWithFormat:#"http://json.myurl.com/....."];
NSString *webStringURL = [strUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString:webStringURL];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSDictionary *tmp = [[NSDictionary alloc] initWithObjectsAndKeys:
#"email", #"Email",
#"password", #"FirstName",
nil];
NSError* error;
NSData* postData = [NSJSONSerialization dataWithJSONObject:tmp options:NSJSONWritingPrettyPrinted error: &error];
NSString *postLength = [NSString stringWithFormat:#"%lu", (unsigned long)[postData length]];
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:postData];
[NSURLConnection sendAsynchronousRequest:request queue:[[NSOperationQueue alloc]init] completionHandler:^(NSURLResponse *response, NSData *jsonData, NSError *error)
{
if (!error)
{
NSDictionary *jsonResponse = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableLeaves error:&error];
dispatch_async(dispatch_get_main_queue(),^
{
NSLog(#"jsonResponse--->%#",jsonResponse);
});
}
else
{
dispatch_async(dispatch_get_main_queue(),^
{
NSLog(#"error--->%#",error.description);
});
}
}];

I need to integrate SMS Verification using Twilio url.
I have ACCOUNT_SID,AUTH_TOKEN and url but not able to parse using Objective C.
CODE:
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:config delegate:self delegateQueue:[NSOperationQueue mainQueue]];
NSString *post = [NSString stringWithFormat:#"From='number'To=%#&Body=message %d to verify your mobile number.",txt_otp.text,[[self sms_verification_code]intValue]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"https://api.twilio.com/2010-04-01/Accounts/(SID)/SMS/Messages"]cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSString *authStr = [NSString stringWithFormat:#"SID:TOKEN"];
NSData *authData = [authStr dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[post dataUsingEncoding:NSUTF8StringEncoding]];
NSString *authValue = [NSString stringWithFormat:#"Basic %#", [authData base64EncodedStringWithOptions:0]];
[request setValue:authValue forHTTPHeaderField:#"Authorization"];
[[session dataTaskWithRequest:request
completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if (!error) {
NSDictionary *responseDictionary = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSLog(#"SMS verification%#",responseDictionary);
}
}] resume];
I have succeeded parsing using AFNetworking SDK.
NSString *kTwilioSID = #"sid";
NSString *kTwilioSecret = #"token";
NSString *kFromNumber = #"";
NSString *kToNumber =#"";
NSString *kMessage = [NSString stringWithFormat:#"message %d",[[self sms_verification_code] intValue]];
NSString *urlString = [NSString
stringWithFormat:#"https://%#:%##api.twilio.com/2010-04-01/Accounts/%#/SMS/Messages/",
kTwilioSID, kTwilioSecret,kTwilioSID];
NSDictionary*
dic=#{#"From":kFromNumber,#"To":kToNumber,#"Body":kMessage};
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer=[AFHTTPResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes=[NSSet setWithObject:#"application/xml"];
[manager POST:urlString parameters:dic progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"success %#",[[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]);
completion:nil];
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
I have a small problem with AFNetworking.
I'm not able to send the parameters and the data to my server (php-Skript)
The data (from NSDictionary) have to be JSON.
Ignore the senseless code parts please.
I'm receiving Errors like:
NSLocalizedDescription=Request failed: unacceptable content-type: text/html}
or Error: Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: text/html"

I am trying to post and JSON data to server.
My JSON is:
{
“username”:”sample”,
“password” : “password-1”
}
The way I am sending it to server is:
NSError *error;
NSString *data = [NSString stringWithFormat:#"{\"username\":\"%#\",\"password\":\"%#\"}",_textFieldUserName.text,_textFieldPasssword.text];
NSData *postData = [data dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSData *jsonData = [NSJSONSerialization JSONObjectWithData:postData options:0 error:&error];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"My URL"]];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:jsonData];
NSURLResponse *requestResponse;
NSData *requestHandler = [NSURLConnection sendSynchronousRequest:request returningResponse:&requestResponse error:nil];
NSDictionary *responseDictionary = [NSJSONSerialization JSONObjectWithData:requestHandler options:0 error:&error];
NSLog(#"resposne dicionary is %#",responseDictionary);
NSString *requestReply = [[NSString alloc] initWithBytes:[requestHandler bytes] length:[requestHandler length] encoding:NSASCIIStringEncoding];
NSLog(#"requestReply: %#", requestReply);
The JsonData that is created is a valid JSON accepted by the server.
But the app is crashing and the error is:
-[__NSCFDictionary length]: unrecognized selector sent to instance 0x1702654c0
what is wrong that i am doing here?
I always use this method in my apps to perform API calls. This is the post method. It is asynchronous so you can specify a callback to be called when the server answer.
-(void)placePostRequestWithURL:(NSString *)action withData:(NSDictionary *)dataToSend withHandler:(void (^)(NSURLResponse *response, NSData *data, NSError *error))ourBlock {
NSString *urlString = [NSString stringWithFormat:#"%#", action];
NSLog(#"%#", urlString);
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dataToSend options:0 error:&error];
NSString *jsonString;
if (! jsonData) {
NSLog(#"Got an error: %#", error);
} else {
jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
NSData *requestData = [NSData dataWithBytes:[jsonString UTF8String] length:[jsonString lengthOfBytesUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json; charset=UTF-8" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%lu", (unsigned long)[requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: requestData];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:ourBlock];
}
}
You can easily call it:
- (void) login:(NSDictionary *)data
calledBy:(id)calledBy
withSuccess:(SEL)successCallback
andFailure:(SEL)failureCallback{
[self placePostRequestWithURL:#"yourActionUrl"
withData:data
withHandler:^(NSURLResponse *response, NSData *rawData, NSError *error) {
NSString *string = [[NSString alloc] initWithData:rawData
encoding:NSUTF8StringEncoding];
NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)response;
NSInteger code = [httpResponse statusCode];
NSLog(#"%ld", (long)code);
if (!(code >= 200 && code < 300)) {
NSLog(#"ERROR (%ld): %#", (long)code, string);
[calledBy performSelector:failureCallback withObject:string];
} else {
NSLog(#"OK");
NSDictionary *result = [NSDictionary dictionaryWithObjectsAndKeys:
string, #"id",
nil];
[calledBy performSelector:successCallback withObject:result];
}
}];
}
And finally, you invocation:
NSDictionary *dataToSend = [NSDictionary dictionaryWithObjectsAndKeys:
_textFieldUserName.text, #"username",
_textFieldPasssword.text, #"password", nil];
[self login:dataToSend
calledBy:self
withSuccess:#selector(loginDidEnd:)
andFailure:#selector(loginFailure:)];
Don't forget to define your callbacks:
- (void)loginDidEnd:(id)result{
NSLog(#"loginDidEnd:");
// Do your actions
}
- (void)loginFailure:(id)result{
NSLog(#"loginFailure:");
// Do your actions
}
First you create an NSString* that is supposed to contain JSON data. This doesn't work in general if the username and password contain any unusual characters. For example, I make sure that I have a quotation mark in my password to make sure that stupid software crashes.
You turn that string into an NSData* using ASCII encoding. So if my username contains any characters that are not in the ASCII character set, what you get is nonsense.
You then use the parser to turn this into a dictionary or array, but store the result into an NSData. Chances are that the parse fails and you get nil, otherwise you get an NSDictionary* or an NSArray*, but most definitely not an NSData*.
Here's how you do it properly: You create a dictionary, and then turn it into NSData.
NSDictionary* dict = #{ #"username": _textFieldUserName.text,
#"password": _textFieldPasssword.text };
NSError* error;
NSData* data = [NSJSONSerialization dataWithJSONObject:dict options:0 error:&error];
That's it.
try this:
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:#"My URL"];
if (!request) NSLog(#"Error creating the URL Request");
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[data dataUsingEncoding:NSUTF8StringEncoding]];
[request setValue:#"text/json" forHTTPHeaderField:#"Content-Type"];
NSLog(#"will create connection");
// Send a synchronous request
NSURLResponse * response = nil;
NSError * NSURLRequestError = nil;
NSData * responseData = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response
error:&NSURLRequestError];
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{

}]; // 2
[alert addAction:firstAction]; // 4

}
}];
// 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"];

[[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
