When I try to call web service using NSURLSession with POST on Apple Watch, response parameter is nil. What might be the issue with this ?
Code for calling web service:
NSURL *url = [NSURL URLWithString:#"https://demo.test.com:22322/api/Alerts/UpdateAlertStatus?intUserId=5¶maccessTokenId=24460c5f-be71-45b5-99cf-f46c277c3d9e&UserId=100200"];
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:config];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
request.HTTPMethod = #"POST";
NSMutableDictionary *mutDictParameters = [[NSMutableDictionary alloc] init];
[mutDictParameters setObject:#"708" forKey:#"AlertId"];
[mutDictParameters setObject:#"2878" forKey:#"XmlMessageId"];
[mutDictParameters setObject:#"5" forKey:#"UserId"];
NSError *error = nil;
NSData *data = [NSJSONSerialization dataWithJSONObject:mutDictParameters
options:kNilOptions error:&error];
if (!error) {
NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:request
fromData:data completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
// Handle response here
NSLog(#"Response : %#",response);
}];
[uploadTask resume];
}

I am trying to use NSURLSession, I had successfully received token from server, now I have to used that Token to get further details...
I had tried below code to get user data..
but I am getting httpResponse code: 500
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];
NSString *authValue = [arrTokenData valueForKey:#"Token"];
//Configure session with common header fields
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.HTTPAdditionalHeaders = #{#"bearer": authValue};
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
NSString *url = #"http://test.myserver.am/api/mobile/LookUps/getuserdata";
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:url]];
NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
if (!error) {
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
if (httpResponse.statusCode == 200)
{
NSDictionary *jsonData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers|NSJSONReadingAllowFragments error:nil];
//Process the data
}
}
}];
[task resume];
I am using iOS 10 , above code is not working, also I have tried several ways but no any success...
I have tried stackoverflow solution but this is also not working out for me...
Please help me out...
I have this method
- (NSString*) createUserWithName:(NSString*)TheName
{
NSURL *URL =someUrlthatIncludesTheName
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
[request setHTTPMethod:#"GET"];
NSURLSession *session = [NSURLSession sharedSession];
NSURL *URL = [NSURL URLWithString:url];
NSURLSessionTask *task = [session dataTaskWithURL:URL completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if (response) {
NSError* error = nil;
NSArray *output = [NSJSONSerialization JSONObjectWithData:data
options:NSJSONReadingMutableContainers
error:&error];
myID = [[output objectAtIndex:0] objectForKey:#"UserID"];
}
}];
[task resume];
return myID;
}
and another method
-(void)doSomethingWith: (NSString*) anID
Somewhere in my code, I call these methods subsequently, like this:
[self createUserWithName:#"John"];
[self doSomethingWith:myID];
However, due to the fact that the NSURLSession in createUserWithName: is asynchronous, doSomethingWith: is fired with myID = (null).
What is the best way to approach this problem, without necessarily falling back to deprecated synchronous NSURLConnection?
Thanks in advance
The workflow is supposed to be
- (void)createUserWithName:(NSString*)TheName
{
NSURL *URL =someUrlthatIncludesTheName
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
[request setHTTPMethod:#"GET"];
NSURLSession *session = [NSURLSession sharedSession];
NSURL *URL = [NSURL URLWithString:url];
NSURLSessionTask *task = [session dataTaskWithURL:URL completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if (response) {
NSError* error = nil;
NSArray *output = [NSJSONSerialization JSONObjectWithData:data
options:NSJSONReadingMutableContainers
error:&error];
myID = [[output objectAtIndex:0] objectForKey:#"UserID"];
[self doSomethingWith:myID];
}
}];
[task resume];
}
And the call is just
[self createUserWithName:#"John"];
The method doSomethingWith: is asynchronously executed in the completion block.
Alternatively use a custom completion block
- (void)createUserWithName:(NSString *)theName completion:^(NSString *identifier)completion
{
NSURL *URL =someUrlthatIncludesTheName
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
[request setHTTPMethod:#"GET"];
NSURLSession *session = [NSURLSession sharedSession];
NSURL *URL = [NSURL URLWithString:url];
NSURLSessionTask *task = [session dataTaskWithURL:URL completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if (response) {
NSError* error = nil;
NSArray *output = [NSJSONSerialization JSONObjectWithData:data
options:NSJSONReadingMutableContainers
error:&error];
myID = [[output objectAtIndex:0] objectForKey:#"UserID"];
completion(myID);
}
}];
[task resume];
}
and call it with
[self createUserWithName:#"John" completion:^(NSString *identifier) {
[self doSomethingWith:identifier];
}];

Use NSURLSession instead. NSURLConnection is deprecated.
NSString *stringURL = [NSString stringWithFormat:#"%#?term=%#", BASE_URL, _inputText.text];
NSURL *URL = [NSURL URLWithString:stringURL];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL];
[request setHTTPMethod:#"POST"];
NSURLSession *session = [NSURLSession sharedSession];
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionUploadTask *task = [session uploadTaskWithRequest:request fromData:yourData completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
// Do your stuff here
}];
why not use alamofire---
NSDictionary *parameters = #{
#"email": #"myemail1#mailinator.com",
#"password": #"123456789",
#"accountnumber": #"LiM6N5gBBmqdlQBJGkqcP0h4OKwGbnzoWFcgTG3Z",
#"ifcscode": #"ABC"
};
NetworkHandler *networHandler = [NetworkHandler sharedInstance];
[networHandler composeRequestWithMethod:#"http://example.com/enpoint.json"
paramas: parameters
onComplition:^(BOOL success, NSDictionary *response){
if (success) { //handle success response
[self handleLoginResponse:response];
}
else{
ProgressIndicator *pi = [ProgressIndicator sharedInstance];
[pi hideProgressIndicator];
}
}];
you can use postman to check your api
Pass this two variables of FirstViewController to SecondViewController and then try to put below code in place of your code.
Below is code to POST data using NSURLSession.
I hope this works for you.
-(void)postData
{
NSString *content = [NSString stringWithFormat:#"Name=%#&Email=%#&A/CName=%#&A/CNumber=%#&IFSCCode=%#&TypeOfAccount=%#",name,email,acName,acNumber,ifscCode,typeOfAccount];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:#"your web service url"]];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[content dataUsingEncoding:NSUTF8StringEncoding]];
NSURLSession *session = [NSURLSession sharedSession];
[[session dataTaskWithURL:[NSURL URLWithString:londonWeatherUrl]
completionHandler:^(NSData *data,
NSURLResponse *response,
NSError *error) {
NSMutableDictionary *dictJson = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
NSLog(#"Dict Json :- %#",dictJson);
}] resume];
}
Send Parameter to web service using POST method
Below is code to POST data to web service using NSURLConnection.
-(void)postData
{
NSString *content = [NSString stringWithFormat:#"email=%#&name=%#",textEmail.text,textName.text];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:#"your web service url"]];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[content dataUsingEncoding:NSUTF8StringEncoding]];
[NSURLConnection connectionWithRequest:request delegate:self];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
dictJson = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
NSLog(#"Dict Json :- %#",dictJson);
}
I am trying to post a string to a server using the next example:
// 1
NSURL *url = [NSURL URLWithString:#"YOUR_WEBSERVICE_URL"];
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:config];
// 2
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
request.HTTPMethod = #"POST";
// 3
NSDictionary *dictionary = #{#"key1": #"value1"};
NSError *error = nil;
NSData *data = [NSJSONSerialization dataWithJSONObject:dictionary
options:kNilOptions error:&error];
if (!error) {
// 4
NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:request
fromData:data completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
// Handle response here
}];
// 5
[uploadTask resume];
}
The difference is that I don't have a NSDictionary But an NSString object that stores an array of dictionaries, and also the string that I post must not be encoded it must be a simple string, so it is visible in the search field if I manually enter it.
My NSString example:
[{
"api_id" = debugger;
at = "2015-02-05T01:41:13Z";
oS = IOS;
ver = "8.10";
what = "showAdAt: forViewController:";
},
{
"api_id" = debugger;
at = "2015-02-05T01:41:13Z";
oS = IOS;
ver = "8.10";
what = "showAdAt: forViewController:";
}
]
Thank you in advance and be patient with me as this is my first post attempt.
I was thinking that the above example should work for me if I first convert the NSString to NSArray with dictionaries as objects.
UPDATE:
Currently I am trying to post the string as:
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.HTTPAdditionalHeaders = #{
#"Authorization" : #"CUSTOM AUTHORIZATION THAT I AM USING",
#"Content-Type" : #"application/json"
};
// Create the session
// We can use the delegate to track upload progress
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration delegate:self delegateQueue:nil];
// Data uploading task. We could use NSURLSessionUploadTask instead of NSURLSessionDataTask if we needed to support uploads in the background
NSURL *url = [NSURL URLWithString:#"MY WEBSITE LINK"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPMethod = #"POST";
//Convert the string to NSData
bodyContainerString = #"[{\"api_id\":\"A124\",\"at\":\"2011-04-10T20:09:31Z\",\"os\":\"ANDROID\",\"ver\":\"2.1\",\"what\":\"TEST\",\"value\":\"\"},{\"api_id\":\"A124\",\"at\":\"2011-04-10T20:10:31Z\",\"os\":\"ANDROID\",\"ver\":\"2.1\",\"what\":\"TEST\",\"value\":\"\"}]";
NSData* jsonData = [bodyContainerString dataUsingEncoding:NSUTF8StringEncoding];
jsonData = [jsonData subdataWithRange:NSMakeRange(0, [jsonData length] - 1)];
NSString* newStr = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
NSLog(newStr);
request.HTTPBody = jsonData;
NSURLSessionDataTask *uploadTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
// Process the response
NSHTTPURLResponse *httpResp = (NSHTTPURLResponse*) response;
if (!error && httpResp.statusCode == 201) {
//if no error on upload then delete content of plist
NSLog(#"Success on post1");
}
NSLog(#"Success on post2");
}];
[uploadTask resume];
Update 2, the resulting link should look like:
curl -X POST http://MY_LINK/smtg -H 'Authorization: CUSTOM_FIRST_HEADER' -H "Content-Type: application/json" -d '[{"api_id":"A124","at":"2011-04-10T20:09:31Z","os":"ANDROID","ver":"2.1","what":"TEST","value":""},{"api_id":"A124","at":"2011-04-10T20:10:31Z","os":"ANDROID","ver":"2.1","what":"TEST","value":""}]'
I ended up using the first example that I found here is my implementation:
NSURL *url = [NSURL URLWithString:#"MY_LINK/smtg"];
//Create thhe session with custom configuration
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.HTTPAdditionalHeaders = #{
#"Authorization" : [NSString stringWithFormat:#"BEARER %#",finalToken],
#"Content-Type" : #"application/json"
};
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
// 2
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
request.HTTPMethod = #"POST";
// 3
NSError *error = nil;
NSData* jsonData = [bodyContainerString dataUsingEncoding:NSUTF8StringEncoding];
if (!error) {
// 4
NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:request
fromData:jsonData completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
// Handle response here
}];
// 5
[uploadTask resume];
}}
I must be missing something basic because I am unable to get any NSURLSession examples using POST to work at all. I have my server set up to print out (to a file that I tail) all the received POST parameters and nothing I put in the POST body shows up. I've tried the solutions from Send POST request using NSURLSession as well as online tutorials such as the Ray Wenderlich Cookbook for using NSURLSession.
Here, for example, is the code almost directly from the Stackoverflow thread, mentioned above, with only the URL and the post arguments changed:
-(void)postTest {
NSString *textContent = #"XXXXX";
NSString *noteDataString = [NSString stringWithFormat:#"x=%#", textContent];
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.HTTPAdditionalHeaders = #{
#"a" : #"YYYYY"
};
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
NSURL *url = [NSURL URLWithString:#"[MY URL with PHP script]"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPBody = [noteDataString dataUsingEncoding:NSUTF8StringEncoding];
request.HTTPMethod = #"POST";
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
outputLabel.text = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
}];
[postDataTask resume];
}
The PHP script shows the "XXXXX" parameter was properly received - but it's not part of the POST body; rather, it is part of the URL itself. The only parameter in the POST body is the "YYYYY" parameter but it doesn't show up at all.
The Ray Wenderlich example didn't work either: nothing showed up for the PHP script.
-(void)testPost {
NSURL *url = [NSURL URLWithString:#"[MY URL with PHP script]"];
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:config];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
request.HTTPMethod = #"POST";
NSDictionary *dictionary = #{#"a": #"YYYYY"};
NSError *error = nil;
NSData *data = [NSJSONSerialization dataWithJSONObject:dictionary options:kNilOptions error:&error];
if (!error) {
NSURLSessionUploadTask *uploadTask =
[session uploadTaskWithRequest:request
fromData:data completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
}];
[uploadTask resume];
}
}
Is there something I'm not setting somewhere? I hadn't expected the shift to NSURLSession would have such subtle boobytraps and I'm wondering if it's something silly I'm doing wrong or missing. Thanks for any help!
Apple Documentation about the request parameter on uploadTaskWithRequest:fromData:completionHandler:
An NSURLRequest object that provides the URL, cache policy, request
type, and so on. The body stream and body data in this request object
are ignored.
