Ios 请求失败：内部服务器错误（500）和Cocoa错误3840，字符0周围的值无效

它似乎在web中工作：

Web响应标题：

    Connection:keep-alive
    Content-Length:394
    Content-Type:application/json
    Date:Sun, 22 Mar 2015 18:36:06 GMT
    Server:nginx/1.6.2
    Vary:Accept-Encoding
    X-Powered-By:Express

Web请求头：

Accept:application/json, text/plain, */*
Accept-Encoding:gzip, deflate
Accept-Language:en-US,en;q=0.8
Authorization:Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJfaWQiOiI1NDVjYzNjYzQ2N2I3YjAyMDBhMWNkOWEiLCJpYXQiOjE0MjcwNDM3Mzk1NjQsImV4cCI6MTQ5MDExNTczOTU2NH0.Xqm-b12QWcEa6MPXyKa1E8m88hGZI9KfJl7Img3mACU
Connection:keep-alive
Content-Length:225
Content-Type:application/json;charset=UTF-8

Web请求有效负载：

{"id":"550f15122cc2708c2d9c65b8","users":["xiruken@gmail.com"],"welcomeMessage":"Hi there. We’ll be using Next24 to keep track of our daily high priority items as a group during this project.","newUser":"xiruken@gmail.com"}

但是在我的原生iOS项目中没有使用objective-C

相同参数：

NSDictionary查询：

AFN网络代码：

使用AFJSONResponseSerializer时出现以下错误：

2015-03-23 03:28:26.773 Next25[5801:302572] Failed! Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (Invalid value around character 0.) UserInfo=0x7fdbb252a6e0 {NSDebugDescription=Invalid value around character 0., NSUnderlyingError=0x7fdbb252c410 "Request failed: internal server error (500)"}

我甚至允许片段，甚至设置了可接受的内容类型

将其更改为AFHTTPResponseSerializer会给我一个不同的错误：

您是否尝试使用Charles来验证请求？它看起来更像是一个请求问题导致了服务器问题和错误响应。我请关闭此线程。我终于找到了答案。我忘了添加这个self.sessionManager.requestSerializer=[AFJSONRequestSerializer]；您需要删除该问题-
