Application 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.

@H_502_5@ 编辑 info.plist，加入如下设置：
<plist>
<dict>
....
<key>NSAppTransportSecurity</key>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
</plist>

切记不要添加到test文件夹下的info.plist文件中，很多同仁放过该错误。@H_502_5@ 原文链接：https://www.f2er.com/swift/324100.html
