How can I log each request/response using AFHTTPSessionManager? - ios

Question

I'm migrating my project to AFNetworking 2.0. When using AFNetworking 1.0, I wrote code to log each request/response in the console. Here's the code:
-(AFHTTPRequestOperation *)HTTPRequestOperationWithRequest:(NSURLRequest *)request
success:(void (^)(AFHTTPRequestOperation *, id))success
failure:(void (^)(AFHTTPRequestOperation *, NSError *))failure
{
AFHTTPRequestOperation *operation =
[super HTTPRequestOperationWithRequest:request
success:^(AFHTTPRequestOperation *operation, id responseObject){
[self logOperation:operation];
success(operation, responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error){
failure(operation, error);
}];
return operation;
}
-(void)logOperation:(AFHTTPRequestOperation *)operation {
NSLog(#"Request URL-> %#\n\nRequest Body-> %#\n\nResponse [%d]\n%#\n%#\n\n\n",
operation.request.URL.absoluteString,
[[NSString alloc] initWithData:operation.request.HTTPBody encoding:NSUTF8StringEncoding],
operation.response.statusCode, operation.response.allHeaderFields, operation.responseString);
}
I'm trying to do the same thing using AFNetworking 2.0, which to my understanding, means using a NSURLSessionDataTask object instead of AFHTTPRequestOperation. Here's my shot at it.
-(NSURLSessionDataTask *)dataTaskWithRequest:(NSURLRequest *)request completionHandler:(void (^)(NSURLResponse *, id, NSError *))completionHandler {
NSURLSessionDataTask *task = [super dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error){
[self logTask:task];
completionHandler(response, responseObject, error);
}];
return task;
}
-(void)logTask:(NSURLSessionDataTask *)task {
NSString *requestString = task.originalRequest.URL.absoluteString;
NSString *responseString = task.response.URL.absoluteString;
NSLog(#"\n\nRequest - %#\n\nResponse - %#\n\n", requestString, responseString);
}
The dataTaskWithRequest:completionHandler method is successfully intercepting each call, so I think that's the right method to override, but when I try to log the task in the completionHandler, task is nil. Thus getting nulls printed in the console. However a proper task object is still returned from that method. What's happening here? How can I properly log the request/response for each call?

Answer 1

you can use the library AFNetworking/AFNetworkActivityLogger
https://github.com/AFNetworking/AFNetworkActivityLogger
from the doc:
AFNetworkActivityLogger is an extension for AFNetworking 2.0 that logs
network requests as they are sent and received.
usage:
[[AFNetworkActivityLogger sharedLogger] startLogging];
output:
GET http://example.com/foo/bar.json
200 http://example.com/foo/bar.json
using devel logging level you should have responseHeaderFields and responseString too
