Ios – Request failed: unacceptable content-type: text/html using AFNetworking 2.0

afnetworkingafnetworking-2ios

I'm trying out the new version 2.0 of AFNetworking and I'm getting the error above. Any idea why this is happening? Here's my code:

    NSURL *URL = [NSURL URLWithString:kJSONlink];
    NSURLRequest *request = [NSURLRequest requestWithURL:URL];
    AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    op.responseSerializer = [AFJSONResponseSerializer serializer];
    [op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"JSON: %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
    [[NSOperationQueue mainQueue] addOperation:op];

I'm using Xcode 5.0.

Also, here's the error message:

Error: Error Domain=AFNetworkingErrorDomain Code=-1016 "Request failed: unacceptable content-type: text/html" UserInfo=0xda2e670 {NSErrorFailingURLKey=kJSONlink, AFNetworkingOperationFailingURLResponseErrorKey=<NSHTTPURLResponse: 0xda35180> { URL: kJSONlink } { status code: 200, headers {
    Connection = "Keep-Alive";
    "Content-Encoding" = gzip;
    "Content-Length" = 2898;
    "Content-Type" = "text/html";
    Date = "Tue, 01 Oct 2013 10:59:45 GMT";
    "Keep-Alive" = "timeout=5, max=100";
    Server = Apache;
    Vary = "Accept-Encoding";
} }, NSLocalizedDescription=Request failed: unacceptable content-type: text/html}

I just hid the JSON using kJSONlink. This should return a JSON.

This means that your server is sending "text/html" instead of the already supported types. My solution was to add "text/html" to acceptableContentTypes set in AFURLResponseSerialization class. Just search for "acceptableContentTypes" and add @"text/html" to the set manually.

Of course, the ideal solution is to change the type sent from the server, but for that you will have to talk with the server team.

By default, AFJSONRequestOperation accepts only "text/json", "application/json" or "text/javascript" content-types from server, but you are getting "text/html".

Fixing on server would be better, but you can also add "text/html" content type as acceptable in your app:

[AFJSONRequestOperation addAcceptableContentTypes:[NSSet setWithObject:@"text/html"]];

It worked for me, hope this helps!

You said in your comment, in response to the suggestion to use the AFHTTPRequestOperationManager:

When I used GET I got this error as I wrote above: Error: Error Domain=AFNetworkingErrorDomain Code=-1016 "Request failed: unacceptable content-type: text/html"

You can remedy that with a AFHTTPResponseSerializer:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager GET:@"https://example.com" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    // do whatever you'd like here; for example, if you want to convert 
    // it to a string and log it, you might do something like:

    NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSLog(@"%@", string);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

You can also use AFHTTPRequestOperation:

NSOperationQueue *networkQueue = [[NSOperationQueue alloc] init];
networkQueue.maxConcurrentOperationCount = 5;

NSURL *url = [NSURL URLWithString:@"https://example.com"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    // do whatever you'd like here; for example, if you want to convert 
    // it to a string and log it, you might do something like:

    NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSLog(@"%@", string);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"%s: AFHTTPRequestOperation error: %@", __FUNCTION__, error);
}];
[networkQueue addOperation:operation];

Ideally, though, it's advisable to write server code that returns JSON (or XML), as that's much easier for an app to consume and parse.
