iOS devices and Android devices may not work with the default HTTPS interception certificates used by Fiddler. To resolve this incompatibility, you may install a Certificate Generating plugin that generates interception certificates compatible with those platforms.

插件直接下载地址

使用方法：关闭fiddler，下载上述插件并安装，然后打开fiddler，Fiddler原来的证书就会失效掉，在手机端重新安装证书并添加信任即可。
