[英]how to get raw JSON response from AFnetworking 2.0 operation / NSURLSessioNDataTask?
This is my code.. its a very simple operation 这是我的代码..它是一个非常简单的操作
[self GET:operationName parameters:params success:^(NSURLSessionDataTask *task, id responseObject) {
NSLog(@"%@", responseObject);
//do something upon success
}
} failure:^(NSURLSessionDataTask *task, NSError *error) {
//do something to handle error
}];
My question is, I need to see what the exact raw json response is.. when I NSLog the responseObject, it's not the same JSON output that I would get from a standalone HTTP client _ I guess its because it's been through the serializer? 我的问题是,我需要看看确切的原始json响应是什么..当我NSLog的responseObject时,它与我从独立的HTTP客户端得到的JSON输出不一样_我猜它是因为它是通过序列化器?
If you don't want it to do the NSJSONSerialization
conversion to NSArray
/ NSDictionary
, but rather want the raw NSData
, you should set the responseSerializer
of the AFURLSessionManager
to a AFHTTPResponseSerializer
. 如果您不希望它将NSJSONSerialization
转换为NSArray
/ NSDictionary
,而是希望原始NSData
,则应将AFURLSessionManager
的responseSerializer
设置为AFHTTPResponseSerializer
。
self.responseSerializer = [AFHTTPResponseSerializer serializer];
The default value is AFJSONResponseSerializer
. 默认值为AFJSONResponseSerializer
。 If you don't want it to convert the JSON for you, change the response serializer. 如果您不希望它为您转换JSON,请更改响应序列化程序。
You can access the “data” object directly from AFNetworking by using the “AFNetworkingOperationFailingURLResponseDataErrorKey” key so there is no need for subclassing the AFJSONResponseSerializer. 您可以使用“AFNetworkingOperationFailingURLResponseDataErrorKey”键直接从AFNetworking访问“数据”对象,因此不需要对AFJSONResponseSerializer进行子类化。 You can the serialize the data into a readable dictionary. 您可以将数据序列化为可读字典。 Here is some sample code : 以下是一些示例代码:
NSData *errorData = error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey];
NSDictionary *serializedData = [NSJSONSerialization JSONObjectWithData: errorData options:kNilOptions error:nil];
It's hard to hook the raw response from AF using their API, and their logger even on Debug level deserializes the JSON before outputting to the console. 使用他们的API挂钩AF的原始响应很困难,甚至在调试级别上他们的记录器也会在输出到控制台之前反序列化JSON。
I added the following line in the AFURLSessionManager.m file. 我在AFURLSessionManager.m文件中添加了以下行。
NSLog(@"Response String: %@", [[NSString alloc] initWithData:[NSData dataWithData:self.mutableData] encoding:NSUTF8StringEncoding]);
in this NSURLSessionTaskDelegate delegate method 在这个NSURLSessionTaskDelegate委托方法中
- (void)URLSession:(__unused NSURLSession *)session task:(NSURLSessionTask *)task didCompleteWithError:(NSError *)error
and here it is in context (for a successful response, without error) 在这里它是在上下文中(为了成功响应,没有错误)
