AFNetworking 2.0上传图片时的错误信息如下：

Error Domain=NSURLErrorDomain Code=-1021 "request body stream exhausted" UserInfo={NSUnderlyingError=0x1522c29d0 {Error Domain=kCFErrorDomainCFNetwork Code=-1021 "request body stream exhausted" UserInfo={NSErrorFailingURLStringKey=http://******/resource_upload, NSLocalizedDescription=request body stream exhausted, NSErrorFailingURLKey=http://******/resource_upload}}, NSErrorFailingURLStringKey=http://******/resource_upload, NSErrorFailingURLKey=http://******/resource_upload, NSLocalizedDescription=request body stream exhausted}

解决方案：

直接添加一个AFURLConnectionOperation的category类，实现如下代码即OK。

#import "AFURLConnectionOperation+AuthenticationChallengeUploadFix.h"@implementation AFURLConnectionOperation (AuthenticationChallengeUploadFix)- (NSInputStream *)connection:(NSURLConnection __unused *)connection needNewBodyStream:(NSURLRequest *)request {    //苹果默认网络请求缓冲区复用，当缓冲区溢出后需要重新开辟缓冲区。否则溢出的数据无法上传服务器。    if ([request.HTTPBodyStream conformsToProtocol:@protocol(NSCopying)]) {               return  [request.HTTPBodyStream copy];         }         return nil;}@end
