I've been getting the following error when using the GET method to retrieve a file from a server:
Error: Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (Invalid value around character 0.) UserInfo=0x16e81ed0 {NSDebugDescription=Invalid value around character 0.}
I've tried a number of different things and I believe it could be something to do with the JSON format on the file that I'm trying to get.
Here is the code I've been using:
_username = @"JonDoe";
NSDictionary *parameters = @{ @"username" : _username};
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"];
[manager GET:@"http://.........."
parameters:parameters
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
My POST method works fine. I just can't seem to fix this issue with the GET. Any ideas? Thank you.
Judging by the discussion in the comments it appears that your GET request is successful (response code 200), but the response body is not valid JSON (nor a JSON fragment) as you have requested by your use of AFJSONResponseSerializer
. A basic AFHTTPResponseSerializer
can be used for responses that are not JSON.
