I am tearing my hair out. The following code refuses to overwrite the previously downloaded file. Any ideas?
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
configuration.requestCachePolicy = NSURLRequestReloadIgnoringLocalCacheData;
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
NSURL *URL = [NSURL URLWithString:#"http://www.google.com/images/srpr/logo11w.png"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL
cachePolicy:NSURLRequestReloadIgnoringLocalCacheData
timeoutInterval:60.0];
NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {
NSURL *documentsDirectoryPath = [NSURL fileURLWithPath:[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject]];
return [documentsDirectoryPath URLByAppendingPathComponent:[response suggestedFilename]];
} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
NSLog(#"File downloaded to: %#", filePath);
NSLog(#"error %#", error );
NSLog(#"response %#", response );
}];
[downloadTask resume];
Use the ephemeral session configuration instead:
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration ephemeralSessionConfiguration];

I am attempting to upload a PNG file to a device, using NSURLDataTask and a "POST" request.
However my attempts always conclude with the device returning a 400 HTTP error code in the response.
My Upload code looks like this:
-(void)uploadMedia:(NSData*)mediaData withName:(NSString*)name andID:(NSString*)mediaID
{
NSString *urlString;
NSString *appToken [self retrieveAppToken];
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:
appToken, #"km-device-auth",
#"application/octet-stream", #"Content-Type",
nil];
sessionConfiguration.HTTPAdditionalHeaders = dict;
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration delegate:self delegateQueue:nil];
urlString = [NSString stringWithFormat:#"https://%#:7788/Media?name=%#&id=%#",_strIP,name,mediaID];
NSLog(#"Attemptive Upload URL:%#",urlString);
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPMethod = #"POST";
request.HTTPBody = mediaData;
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSLog(#"My respone:%#:%#",response,data);
}];
[postDataTask resume];
}
SOLVED
My headers also required a value for "Content-MD5" which was missing.
I am trying to fetch JSON data and parse it using NSUrl session but getting null every time - Also in addition to that i want o show all data in table view
NSError *error;
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURL *url = [NSURL URLWithString:#"https://dl.dropboxusercontent.com/s/2iodh4vg0eortkl/facts.json"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
[request addValue:#"text/plain" forHTTPHeaderField:#"Content-Type"];
[request addValue:#"text/plain" forHTTPHeaderField:#"Accept"];
[request setHTTPMethod:#"GET"];
NSDictionary *mapData = [[NSDictionary alloc] initWithObjectsAndKeys: #"Value", #"Key", nil];
NSData *postData = [NSJSONSerialization dataWithJSONObject:mapData options:0 error:&error];
[request setHTTPBody:postData];
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSLog(#"Resopnse == %#",response);
if (response != nil) {
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSLog(#"JSon dict === %#",jsonDict);
}
}];
[postDataTask resume];
May I know what i am doing wrong is anything other good way to do same?
Try following code.
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"https://dl.dropboxusercontent.com/s/2iodh4vg0eortkl/facts.json"]];
[request setHTTPMethod:#"GET"];
[request addValue:#"text/plain" forHTTPHeaderField:#"Content-Type"];
[request addValue:#"text/plain" forHTTPHeaderField:#"Accept"];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSString *requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
NSData * responseData = [requestReply dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
NSLog(#"requestReply: %#", jsonDict);
}] resume];
Please use the below code for the same. Hope it will solve your problem.
NSString *strUrl = [NSString stringWithFormat:yourUrl];
NSURL *url = [NSURL URLWithString:strUrl];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[NSURLConnection sendAsynchronousRequest:request
queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response,
NSData *data, NSError *connectionError)
{
if (data.length > 0 && connectionError == nil)
{
NSDictionary *dicResponse = [NSJSONSerialization JSONObjectWithData:data options:0 error:NULL];
NSLog(#"%#",dicResponse);
}
}];
How to retrieve the actual file/Data after doing some check inside this decidePolicyForNavigationResponse delegate method:
- (void)webView:(WKWebView *)webView decidePolicyForNavigationResponse:(WKNavigationResponse *)navigationResponse decisionHandler:(void (^)(WKNavigationResponsePolicy))decisionHandler
{
NSHTTPURLResponse *response = (NSHTTPURLResponse *)navigationResponse.response;
}
Any leads are welcomed...Thank you
I'm a beginner but if you want to download a file on a WKWebview, you need to use AFNetworking, the code looks like this :
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
NSURL *URL = WebView.URL;
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {
NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];
return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];
} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
NSLog(#"File downloaded to: %#", filePath);
}];
[downloadTask resume];
Hope this helps you
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 want to post a request to server. It is working fine if I am using NSURLSessionDataTask. But underneath I need to use AFNetworking as my whole application is using it. But when I am trying to hit the same service in AFHTTPSessionManager with POST method, It is giving me request time out.
Below are both the codes.
NSError *error;
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:nil delegateQueue:nil];
NSURL *url = [NSURL URLWithString:#"BASE URL"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
[request addValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request addValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setHTTPMethod:#"POST"];
NSString *postString = #"1";
NSData *data = [postString dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody:data];
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
}];
[postDataTask resume];
AFNetworking kit version :-
AFHTTPSessionManager *client = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:#"BASE URL"]];
NSDictionary *request = #{#"Content-Type":#"application/json",
#"Accept":#"application/json",
};
NSString *postString = #"1";
NSData *data = [postString dataUsingEncoding:NSUTF8StringEncoding];
[client POST:#"" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithHeaders:request body:data];
} success:^(NSURLSessionDataTask *task, id responseObject) {
NSLog(#"%#",responseObject);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(#"%#",error);
}];
Please help me in implementing it in right way.
I solved this problem by creating my own request and give its configuration to AFURLSessionManager and then holding my own NSURLSessionUploadTask object.
Thanks
