Question

我将我的项目迁移到AFNetworking 2.0。使用AFNetworking 1.0时，我编写了代码来记录控制台中的每个请求/响应。这是代码：

-(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);
}

我尝试使用AFNetworking 2.0做同样的事情，根据我的理解，这意味着使用NSURLSessionDataTask对象而不是AFHTTPRequestOperation。这是我拍摄的。

-(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);
}

dataTaskWithRequest:completionHandler方法成功拦截每个调用，因此我认为这是正确的覆盖方法，但是当我尝试在completionHandler中记录任务时，task为零。因此在控制台中打印空值。但是，仍然从该方法返回适当的任务对象。这里发生了什么？如何正确记录每次通话的请求/响应？

您可以使用库AFNetworking / AFNetworkActivityLogger

https://github.com/AFNetworking/AFNetworkActivityLogger

来自doc：

AFNetworkActivityLogger是AFNetworking 2.0的扩展记录发送和接收网络请求。

用法：

[[AFNetworkActivityLogger sharedLogger] startLogging];

输出：

GET http://example.com/foo/bar.json
200 http://example.com/foo/bar.json

使用devel日志记录级别，你应该有responseHeaderFields和responseString

如何使用AFHTTPSessionManager记录每个请求/响应？
