iOS9.0以后出于对请求安全的考虑默认将Foundation.framework中的HTTP请求协议更换为SSL/TLS,也就是说所有由程序发起的HTTP请求默认将请求HTTPS的内容,而且在HTTPS出现404时不会请求HTTP的内容,如果你的APP原来就使用HTTPS,基本问题不大,但是如果使用HTTP的话,就需要:
1.修改你的服务器配置,使它支持HTTPS访问
2.修改你的info.plist配置,让APP能访问普通的HTTP协议网站
否则调试程序时会在Log中出现以下提示:
- 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.
复制代码修改info.plist时,APPLE也提供了修改方法,在info.plist中增加以下内容即可
- <key>NSAppTransportSecurity</key>
- <dict>
- <key>NSExceptionDomains</key>
- <dict>
- <!--your domain-->
- <key>lidaren.com</key>
- <dict>
- <!--Include to allow subdomains-->
- <key>NSIncludesSubdomains</key>
- <true/>
- <!--Include to allow insecure HTTP requests-->
- <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
- <true/>
- <!--Include to specify minimum TLS version-->
- <key>NSTemporaryExceptionMinimumTLSVersion</key>
- <string>TLSv1.1</string>
- </dict>
- </dict>
- </dict>
复制代码如果你的app具有浏览器功能,可以这样改,就可以完全放开HTTP访问功能了
- <key>NSAppTransportSecurity</key>
- <dict>
- <!--Connect to anything (this is probably BAD)-->
- <key>NSAllowsArbitraryLoads</key>
- <true/>
- </dict>
