iOS 发送HTTP请求报错：

App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app’s Info.plist file.

原因／解决办法：

iOS 的网络请求要求的安全性比较高都是https格式的，如果非要使用http格式的，就必须在info.plist文件中进行修改，允许使用安全性较低的http格式的，如下图在info.plist 中输入App Transport Security Settings ====>Allow Arbitrary Loads -> YES
