我收到这个错误Domain = AFNetworkingErrorDomain Code = -1011“请求失败：内部服务器错误(500).任何人可以告诉我我在这里做错了什么？
得到这个回应：

{ status code: 500,headers {    "Cache-Control" = private;    "Content-Length" = 509;    "Content-Type" = "application/soap+xml; charset=utf-8";    Date = "Thu,13 Mar 2014 12:59:45 GMT";    Server = "Microsoft-IIS/7.5";    "X-AspNet-Version" = "2.0.50727";    "X-Powered-By" = "ASP.NET";} }

解决方法 你的代码有：

[self POST:GET_CAR_BRAND parameters:Nil constructingBodyWithBlock:^(ID<AFMultipartFormData> formData) {          [formData appendPartWithheaders:[NSDictionary dictionaryWithObjectsAndKeys:@"text/xml; charset=utf-8",nil] body:[soapRequest dataUsingEnCoding:NSUTF8StringEnCoding]];

它将content-type定义为“text / xml”,而服务器显然期待“application / soap xml”.您应该尝试将该部分代码更改为：

[self POST:GET_CAR_BRAND parameters:Nil constructingBodyWithBlock:^(ID<AFMultipartFormData> formData) {          [formData appendPartWithheaders:[NSDictionary dictionaryWithObjectsAndKeys:@"application/sopa+xml; charset=utf-8",nil] body:[soapRequest dataUsingEnCoding:NSUTF8StringEnCoding]];

更新建议：

尝试添加：

[self.requestSerializer setValue:@"application/soap+xml; charset=utf-8" forhttpheaderFIEld:@"Content-Type"];

在你的 – (instancetype)initWithBaseURL：(NSURL *)url方法的最后.

如果这没有帮助,我建议做一些更详细的网络请求调试.你可以设置AFNetworkActivityLogger将请求/响应信息记录到控制台.
