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: 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"; }

Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: bad request (400)" UserInfo={com.alamofire.serialization.response.error.response= { URL: 121.42.203.122:8080/8minutes/uploadImg } { status code: 400, headers { Connection = close; "Content-Language" = en; "Content-Length" = 1105; "Content-Type" = "text/html;charset=utf-8"; Date = "Fri, 11 Dec 2015 05:36:46 GMT"; Server = "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.
