I have a web service which when hit on web browser asks for username and password. I have to integrate same web service in my mobile app.
I searched a lot and got link which helps in implementing NTLM Authentication via AFNetworking.
Now under success block I am not getting response data. I am getting 0 records.
Success: {"records":[]}
Whereas hitting service on web browser I get all the records.
below is my code
NSString *str = #"complete web service url";
NSString *encode = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSURLCredential *credential = [NSURLCredential credentialWithUser:#"userName" password:#"password" persistence:NSURLCredentialPersistenceNone];
NSMutableURLRequest *request = [manager.requestSerializer requestWithMethod:#"GET" URLString:encode parameters:nil error:nil];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCredential:credential];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[manager.requestSerializer setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %#", [operation responseString]);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Failure: %#", error);
}];
[manager.operationQueue addOperation:operation];
Can anyone help me please that what is causing the problem. Thanks in advance.

There are other questions with similar titles but none of them helped me. I've to send a PUT request to server in order to change the status of appointment so I've made this method -(void)appointmentStatusChangedTo:(NSString *)statusID atAppointmentID:(NSString *)appointmentID In which I'm setting the URL and Parameters as
NSString *string = [NSString stringWithFormat:#"%#/API/Appointments/3",BaseURLString];
NSDictionary *para = #{
#"AppointmentStatusId":statusID,
#"ID":appointmentID
};
Then I've made URL request as
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:#"PUT" URLString:string parameters:para error:nil];
After that I'm setting the header for an authorization token as
NSString *token = [NSString stringWithFormat:#"Bearer %#",[[NSUserDefaults standardUserDefaults] objectForKey:#"userToken"]];
[req setValue:token forHTTPHeaderField:#"Authorization"];
So finally I'm calling it as
[[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error){
if (!error) {
if (response) {
NSLog(#"Respose Object: %#",responseObject);
[self.patientsAppointmentsTableView reloadData];
}
}
else {
// NSLog(#"Error: %#, %#, %#", error, response, responseObject);
NSLog(#"Error: %#", error.localizedDescription);
}
}] resume];
Now it is successfully sending the data to the server but as a response I'm getting
Error: The data couldn’t be read because it isn’t in the correct
format.
I am not sure what the response might look like at the moment as I'm not in contact with backend guy. But as far as I remember it was just a simple 1. SO kindly tell me how to handle any type of response using AFNetworking 3.0 or any change in my code.
try to use below code:
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
[serializer setStringEncoding:NSUTF8StringEncoding];
manager.requestSerializer=serializer;
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
Try following code using Afnetworking 3.0
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager GET:url parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"%#",responseObject);
self.responseHandlers(YES,responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
self.responseHandlers(NO,nil);
}];
Trying to use the postmates api, but running into issues with authorization.
To quote their site:
AUTHENTICATION
The Postmates API requires authentication by HTTP Basic Auth headers.
Your API key should be included as the username. The password should
be left empty.
The actual header that is used will be a base64-encoded string like
this:
Basic Y2YyZjJkNmQtYTMxNC00NGE4LWI2MDAtNTA1M2MwYWYzMTY1Og==
I tried using AFNetworking like so
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSURLCredential *credential = [NSURLCredential credentialWithUser:#"(my postmates key)" password:#"" persistence:NSURLCredentialPersistenceNone];
NSMutableURLRequest *request = [manager.requestSerializer requestWithMethod:#"GET" URLString:#"https://api.postmates.com/v1/delivery_zones" parameters:nil];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCredential:credential];
[operation setResponseSerializer:[AFJSONResponseSerializer alloc]];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Failure: %#", error);
}];
[manager.operationQueue addOperation:operation];
The error message I'm getting is
Incorrect NSStringEncoding value 0x0000 detected. Assuming NSASCIIStringEncoding. Will stop this compatiblity mapping behavior in the near future.
Success: {
code = "invalid_authorization_header";
kind = error;
message = "Your API key was not formatted properly";
}
Instead of creating a credential, you might want to try:
[request setValue:#"Basic Y2YyZjJkNmQtYTMxNC00NGE4LWI2MDAtNTA1M2MwYWYzMTY1Og==" forHTTPHeaderField:#"Authorization"];
I am trying to use AFHTTPRequestOperationManager to make an HTTP request. I need to use AFHTTPRequestOperationManager because I want to be able to cancel all operations if necessary. I can't get this working for some reason. The completion blocks aren't called. Am I missing something?
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"https://twitter.com/%#", username]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setValue:#"MyUserAgent (iPhone; iOS 7.0.2; gzip)" forHTTPHeaderField:#"User-Agent"];
[request setHTTPMethod:#"GET"];
[self.manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *html = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
if ([html containsString:#"var h = decodeURI(l.hash.substr(1)).toLowerCase();"]) {
completion(YES, nil);
} else {
completion(NO, nil);
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
completion(NO, error);
}];
This is working code, you need to use GET or POST method there.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = #{#"email":emailfield.text};
[manager GET:#"http://example.com/api" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
While everyone else is right -- you should be using the modern AFNetworking constructs instead of the legacy features -- there is a quick way to get done what you're looking to get done.
By the looks of it, the method - (??? *) HTTPRequestOperationWithRequest:success:failure likely returns an AFHTTPRequestOperation. If I'm correct, you just need to actually start the operation. See below for your code, corrected.
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"https://twitter.com/%#", username]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setValue:#"MyUserAgent (iPhone; iOS 7.0.2; gzip)" forHTTPHeaderField:#"User-Agent"];
[request setHTTPMethod:#"GET"];
AFHTTPRequestOperation *op = [self.manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *html = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
if ([html containsString:#"var h = decodeURI(l.hash.substr(1)).toLowerCase();"]) {
completion(YES, nil);
} else {
completion(NO, nil);
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
completion(NO, error);
}];
[op start];
HTTPRequestOperationWithRequest method returns AFHTTPRequestOperation. You have to add it to some operation queue to start it. For example
AFHTTPRequestOperation *operation = [self.manager HTTPRequestOperationWithRequest:request .........
[[NSOperationQueue currentQueue] addOperation:operation];
You can use AFHTTPSessionManager which is a little better than AFHTTPRequestOperationManager and cancel requests using method cancel of NSURLSessionDataTask. You can find some code examples here - AFNetworking 2.0 cancel specific task
Check this will work
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:#"application/json", nil];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager POST:url parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
}];
I want to use AFNetworking class to my application to communicating with server.
I am new to this library . Here is my code:
NSDictionary *user=[[NSDictionary alloc]initWithObjectsAndKeys:#"hiteshp",#"userName",#"12345^",#"password", nil];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
AFHTTPRequestSerializer *requestSerializer = [AFHTTPRequestSerializer serializer];
[requestSerializer setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
manager.requestSerializer=requestSerializer; //[AFJSONRequestSerializer serializer];
[manager POST:#"myURL" parameters:user success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %# %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
I want to add header to this request . I tried but it is not working . If I wrote commented line then request is done but I also want to add one more field "Authorization" to requset.
Andhow to print request header?
I know it's too late but here's a code that makes what you want
NSString *finalyToken = [[NSString alloc]initWithFormat:#"Bearer %#",user.token];
AFHTTPRequestOperationManager *manager =
[[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:#"https://server1.appscserver.de/api"]];
[manager.requestSerializer setValue:finalyToken forHTTPHeaderField:#"Authorization"];
Hope it helps someone
Use this in your code:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:#"text/html", #"application/json", nil];
//Authorization
[manager.requestSerializer setAuthorizationHeaderFieldWithUsername:userName password:password];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
in php file add:
header('Content-type: application/json');
in xcode:
manager.responseSerializer = [AFJSONResponseSerializer serializer];
example xcode code:
NSDictionary *parameters = #{#"key1": #"value1",
#"key2": #"value2"};
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager POST:[NSString stringWithFormat:#"http://%#", Url] parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
I am trying to write code for an SDK. I need to make API calls.
I am using AFNetworking 2.0 to send a POST request to the server:
NSDictionary * params = [self formDictionaryFromCard: card];
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] requestWithMethod:#"POST" URLString: [self apiUrl] parameters: params];
[request addValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request addValue:#"Firefox" forHTTPHeaderField:#"User-Agent"];
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
op.responseSerializer = [AFJSONResponseSerializer serializer];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
successBlock(responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
errorBlock(error);
}];
[[NSOperationQueue mainQueue] addOperation:op];
So far I have the above, but I can't figure out how to pass in headers (like the authorization header), or provide support for https.
Can anyone please help?
Also how can I know what http status code was returned?
