AFNetworking返回400错误请求 [英] AFNetworking return 400 bad request

问题描述

我想通过AFNetworking发布图片，这是代码

i want to post image by AFNetworking,here is the code

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
[manager POST:URL parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData){
     [formData appendPartWithFileData:UIImageJPEGRepresentation(selfPhoto, 1) name:@"file" fileName:imageFilePath mimeType:@"image/jpg"];
 }

但返回400错误请求，这是错误消息:

but return 400 bad request,here is the errro:

Domain = com.alamofire.error.serialization.response代码= -1011请求 失败:错误的请求(400)" UserInfo = {com.alamofire.serialization.response.error.response = {URL: http://121.42.203.122 :8080/8minutes/uploadImg } {状态码:400，标题{ 连接=关闭； "Content-Language" = zh; 内容长度" = 1105； "Content-Type" =文本/html; charset = utf-8"; 日期=星期五，2015年12月11日05:36:46 GMT"； 服务器="Apache-Coyote/1.1"; }

这是网络服务网址键:

  param:{"file"}

我错了吗?

推荐答案

这是因为您收到的响应采用" text/html "格式，因此应采用 application/json 格式.

Its because the response you are getting is in "text/html" format it should be in application/json format.
