使用AFHTTPRequestOperationManager时响应失败
当我尝试使用确切的用户名和密码调用API（AFHTTPRequestOperationManager）进行身份validation方法时获得准确的响应并且方法成功。 然后我尝试使用无效的用户名和密码我得到的回复是失败的。
我尝试ASIHTTPRequest API相同的方法，它的工作正常。 所以请检查以下请求和回复，并建议我如何解决这个问题。 但是在AFHTTPRequestOperationManager中无效的用户响应是失败的。
ASIHTTPRequest CALL示例：
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[ NSURL URLWithString:[SharedUtil URLByKey:@"A_URL"]]]; request.shouldAttemptPersistentConnection=NO; [request setRequestMethod:@"POST"]; [request addRequestHeader:@"enctype" value:@"application/x-www-form-urlencoded"]; [request addRequestHeader:@"Authorization" value:[SharedUtil authorizationHeader ]]; [request addRequestHeader:@"Accept" value:@"application/json"]; [request setValidatesSecureCertificate:NO]; [request setPostValue:@"pa" forKey:@"type"]; [request setPostValue:username forKey:@"username"]; [request setPostValue:password forKey:@"password"]; [request setDelegate:self]; [request setTimeOutSeconds:120]; [self setTimer]; [request setDidFinishSelector: @selector(responseAuthUserSuccess:)]; [request setDidFailSelector: @selector(responseAuthUserFailed:)]; [post release]; // Cancels an asynchronous request [networkQueue addOperation: request]; 响应是ASIHTTPRequest，方法是成功的
{“error”：“invalid_grant”，“error_description”：“无法validation用户sdsdds@gmail.com”}
使用AFHTTPRequestOperationManager CALL示例：
AFHTTPRequestOperationManager *managerAF = [AFHTTPRequestOperationManager manager]; NSDictionary *params = @{ @"type": @"pa", @"username": username, @"password": password }; [managerAF.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"]; [managerAF.requestSerializer setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"enctype"]; [managerAF.requestSerializer setValue:[SharedUtil authorizationHeader] forHTTPHeaderField:@"Authorization"]; managerAF.responseSerializer = [AFJSONResponseSerializer serializer]; managerAF.securityPolicy.allowInvalidCertificates = YES; [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES]; [managerAF POST:[SharedUtil URLByKey:@"A_URL"] parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) { NSData* data=[operation.responseString dataUsingEncoding:NSUTF8StringEncoding]; } [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO]; } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error); [self stopTimer]; }];
AFHTTPRequestOperationManager响应和方法失败：
Printing description of error: Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: bad request (400)" UserInfo=0xd3b7670 {NSErrorFailingURLKey=https://example.com/token, com.alamofire.serialization.response.error.response= { URL: https://example.com/token } { status code: 400, headers { "Cache-Control" = "no-store"; Connection = "keep-alive"; "Content-Type" = "application/json;charset=UTF-8"; Date = "Fri, 25 Jul 2014 05:15:19 GMT"; Pragma = "no-cache"; Server = "nginx/1.6.0"; "Transfer-Encoding" = Identity; "X-Powered-By" = "Servlet/3.0 JSP/2.2 (GlassFish Server Open Source Edition 3.1.2.2 Java/Oracle Corporation/1.7)"; } }, NSLocalizedDescription=Request failed: bad request (400)}
你的命中失败因为api你的命中返回了一个400的http响应代码而AFNetworking正确地将其解释为错误。 通过使用故障块中提供的AFHTTPRequestOperation对象的responseData和responseString属性，您仍然可以从响应中获取更详细的数据。
