AFNetworking 2.0: NSLocalizedDescription = Request failed: inappropriate content type: text / html

Question

I tried GET html from the Apple homepage.

AFHTTPRequestOperationManager *manager
= [AFHTTPRequestOperationManager manager];
[manager GET:@"http://www.apple.com/jp" parameters:nil
     success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"HTML: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

This failed with an error message as shown below:

2014-02-07 14:54:22.922 Tests[1833:70b] Error: Error Domain=AFNetworkingErrorDomain Code=-1016 "Request failed: unacceptable content-type: text/html" UserInfo=0x8a32650 {NSErrorFailingURLKey=http://www.apple.com/jp/, AFNetworkingOperationFailingURLResponseErrorKey=<NSHTTPURLResponse: 0xea2e1a0> { URL: http://www.apple.com/jp/ } { status code: 200, headers {
    "Accept-Ranges" = bytes;
    "Cache-Control" = "max-age=237";
    Connection = "keep-alive";
    "Content-Encoding" = gzip;
    "Content-Length" = 4402;
    "Content-Type" = "text/html; charset=UTF-8";
    Date = "Fri, 07 Feb 2014 05:52:51 GMT";
    Expires = "Fri, 07 Feb 2014 05:56:48 GMT";
    Server = Apache;
    Vary = "Accept-Encoding";
    Via = "1.0 proxy1.screen.co.jp (squid)";
    "X-Cache" = "MISS from proxy1.screen.co.jp";
    "X-Cache-Lookup" = "HIT from proxy1.screen.co.jp:8080";
} }, NSLocalizedDescription=Request failed: unacceptable content-type: text/html}

I found the message Request failed: unacceptable content-type: text/html, so I understand that I must allow the use of text / html. Then I added the line: manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];.

AFHTTPRequestOperationManager *manager 
= [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes
= [NSSet setWithObject:@"text/html"]; // ###### ADDED LINE ######
[manager GET:@"http://www.apple.com/jp" parameters:nil
     success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"HTML: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

But this also failed.

Thank you for your help.

Answer 1

The problem is what AFHTTPRequestOperationManagerthe default matches responseSerializer AFJSONResponseSerializer. By changing acceptableContentTypes, you change what types of content will be accepted, but you do not change the fact that you AFJSONResponseSerializerwill still look for JSON in the response.

responseSerializer AFHTTPResponseSerializer, JSON ( text/html):

manager.responseSerializer = [AFHTTPResponseSerializer serializer];

Answer 2

wget, "jp" 301 .

"jp/".
