使用Swift

问题描述 投票：0回答：1
来工作。从我的代理服务器中可以看到，当我调用此功能时，它实际上是从iOS应用程序中获取请求的。但是，我在下面得到错误响应。我假设关于我对

httpbin.org

的要求是错误的，但我无法弄清楚。阵列中的代理正在工作，如果您想测试，可以随意使用。

问题是字符串中HTTP请求的格式。正确格式是：




swift

http

network-programming

https

request

let httpRequest = "GET /get HTTP/1.1\r\nHost: httpbin.org\r\nConnection: close\r\nAccept: */*\r\nUser-Agent: MySwiftApp/1.0\r\n\r\n"


该代码启用Swift中的请求可以利用Auth的代理。我发现在Swift中验证代理的唯一方法是与
NWConnection
一起。所有其他本机方法都无法使用。
