AFNetworking response failure block is called instead of success block - ios

Question

AFNetworking response failure block is being called when I get status code 200. How can I make the success be called instead?
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:#"http://128.199.94.58/test/bt/client_token.php" parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject) {
self.clientToken = responseObject[#"customerID"];
NSLog(#"Client Token received.");
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
// Handle failure communicating with your server
NSLog(#"Client Token request failed.%#",operation.responseString);
NSLog(#"error code %ld",(long)[operation.response statusCode]);
}];

Answer 1

Look at the value of error. It will tell you why the connection failed. "Failure" in this context has nothing to do with the status code. Returning "404" is still a "success." Failure means you were unable to complete the operation.

Answer 2

use acceptableStatusCodes as follows:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [TimeoutAFJSONRequestSerializer serializer];
NSMutableIndexSet* codes = [[NSMutableIndexSet alloc] init];
[codes addIndex: 200];
manager.responseSerializer.acceptableStatusCodes = codes;
[manager GET:urlString parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject)
{
} failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
}];

Answer 3

I run this code and it work find.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager GET:#"http://128.199.94.58/test/bt/client_token.php" parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseObject
options:kNilOptions
error:nil];
self.clientToken = json[#"customerID"];
NSLog(#"Client Token received.");
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
// Handle failure communicating with your server
NSLog(#"Client Token request failed.%#",operation.responseString);
NSLog(#"error code %ld",(long)[operation.response statusCode]);
}];
responce is:
json:
{
customerID = "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";

It may be work for you.

Answer 4

If you check your error in failure block it clearly say that invalid content type. You need to set the content type of the manager as follows
manager.requestSerializer = [AFJSONRequestSerializer serializer];

Answer 5

try this
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
and in success block
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:manager.responseData options:kNilOptions error:nil];
self.clientToken = dic[#"customerID"];
NSLog(#"Client Token received.");
}
