我在AFNetworking issues中的回答how to get response body in failure block?还有
How can i get responseString which at AFNetworking 3.0
发现还有好多朋友还不清楚如何实现,其实很简单
NSError *underError = error.userInfo[@"NSUnderlyingError"];
NSData *responseData = underError.userInfo[@"com.alamofire.serialization.response.error.data"];
有小伙伴问我com.alamofire.serialization.response.error.data是怎么来的,原来都是AFJSONResponseSerializer解析修改成manager.responseSerializer = [AFHTTPResponseSerializer serializer];这样报错的时候就会看到控制台打印的信息里面有com.alamofire.serialization.response.error.data后面输出responseData...然后才有了上面的解决办法

作者回复中已经添加了相关操作
在AFURLResponseSerialization
可以在 failure block 中添加下面代码获取responseString
NSData *data = error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey];
具体代码:
/**
## User info dictionary keys
These keys may exist in the user info dictionary, in addition to those defined for NSError.
- `NSString * const AFNetworkingOperationFailingURLResponseErrorKey`
- `NSString * const AFNetworkingOperationFailingURLResponseDataErrorKey`
### Constants
`AFNetworkingOperationFailingURLResponseErrorKey`
The corresponding value is an `NSURLResponse` containing the response of the operation associated with an error. This key is only present in the `AFURLResponseSerializationErrorDomain`.
`AFNetworkingOperationFailingURLResponseDataErrorKey`
The corresponding value is an `NSData` containing the original data of the operation associated with an error. This key is only present in the `AFURLResponseSerializationErrorDomain`.

FOUNDATION_EXPORT NSString * const AFNetworkingOperationFailingURLResponseErrorKey;
FOUNDATION_EXPORT NSString * const AFNetworkingOperationFailingURLResponseDataErrorKey;
