Question

我正试图从AlamoFire转移到NSURLSessions并尝试向返回GET（字典数组）的端点发出JSON请求。

以下是来自Alamofire代码的标题成功：

GET /Path/?lastrequest=2006-08-25T03:25:21Z HTTP/1.1
Host    one.domain.com
Cookie  connect.sid=s%3A8gUYZmxHWn9PJ95ZJF9P6FGrdrcPIueG.KcXee%2FT8VI1SeAaVvOwcHdOuCLydPvU%2BLiqlZHu2QfI

Accept  */*

Accept-Language en-US;q=1.0
Accept-Encoding gzip;q=1.0,compress;q=0.5
Connection  keep-alive

AlamoFire Successful回复信息：

Response Header 173 bytes

Response Code   200 OK

Content-Type    application/json; charset=utf-8

现在使用失败的NSURLSession标题：

GET /Path/?lastrequest=2006-08-25T03:25:21Z HTTP/1.1
Host    one.domain.com
Accept  */*
Connection  keep-alive

Accept-Language en-US;q=1.0
Content-Length  2
Accept-Encoding gzip;q=1.0,compress;q=0.5

NSURLSession 失败回复信息：

我确实在header中看到了与AlamoFire不相符的额外字段，但我不知道如何关闭它们。

NRURLSession 也会进行3-4次并发呼叫。

NSURLSession 失败回复：

Response:  Failed to parse data (org.json.JSONException: A JSONObject text must begin with '{' at character 1) 

Failure Client closed connection before receiving entire response
Response Code   200 OK
Protocol    HTTP/1.1
Method  GET
Kept Alive  No
Content-Type    application/json; charset=utf-8
Client Address  /127.0.0.1

以下是我在header中配置的NSURLSession：

 var headers: [String: String]? {
            return ["x-token" : token!,
                    "Accept-Encoding": "gzip;q=1.0,compress;q=0.5",
                    "Accept-Language": "en-US;q=1.0"]

我做错了什么？

Answer 1

Content-Length = 2一直显示在标题中的原因是因为我正在为字典发送一个空字符串。当我发送一个nil时，它的作品很有魅力。

iOS9 - NSURLSession无法解析响应，但AlamoFire可以正常工作
