预期状态代码（200-299），得到500

Question

我从服务器获取数据。服务器端是从客户端维护。我只是解析数据并使用AFNetworking。但可能是某些SOAPACtion有错误。服务器无法识别HTTP标头SOAPAction的值：http://test.server.com/Role

HTTP POST：

POST /service/services.asmx/Role HTTP/1.1
Host: server.com
Content-Type: application/x-www-form-urlencoded
Content-Length: length

SyncResetData=string

代码：

NSString *soapMessage = [NSString stringWithFormat:@"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
                             "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
                             "<soap:Body>\n"
                             "<Sync_Reset_Role xmlns=\"http://test.server.com/\">\n"
                             "<SyncResetData><![CDATA[%@]]></SyncResetData>\n"
                             "</Sync_Reset_Role>\n"
                             "</soap:Body>\n"
                             "</soap:Envelope>\n",string];


    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://%@/services.asmx?wsdl/Role",SERVICE_ENDPOINT]];


     NSLog(@"url is getResetRoleContentLength %@",url);

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
    NSString *strLength = [NSString stringWithFormat:@"%d",[soapMessage length]];

    [request addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [request addValue: [NSString stringWithFormat:@"http://test.server.com/Role"] forHTTPHeaderField:@"SOAPAction"];
    [request addValue: strLength forHTTPHeaderField:@"Content-Length"];
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];


         AFHTTPRequestOperation *operation2 = [[AFHTTPRequestOperation alloc] initWithRequest:request];

    [operation2 setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation2, id responseObject2) {


    } failure:^(AFHTTPRequestOperation *operation2, NSError *error) {

        NSLog(@"Error: %@", error);


        if([delegate respondsToSelector:@selector(requestFailed)]){
            [delegate performSelector:@selector(requestFailed)];
        }


    }];

错误：
