使用Charles遇到的问题

问题1：证书检验不通过

错误： Cause: unable to find valid certification path to requested target

使用命令行报的详细错误： Caused by: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

原因： 设置了SSL Proxying里的include项为*: *,导致Charles抓取了所有网址的数据，导致证书验证不通过，如下图：

解决方案： 在SSL Proxying里的exclude项将远程地址添加进去，远程地址如下：

https://jcenter.bintray.com

https://jitpack.io

https://repo1.maven.org

https://maven.aliyun.com

https://dl.google.com

问题2：抓取Https包乱码

错误： 如下图示例

原因： 未安装证书

解决方案：

安装本地证书，以Mac为例，步骤如下：
1. Help -> SSL Proxying -> Install Charles Root Certificate，如图
2. 找到CharlesProxy的证书，在信任里加密套接字协议层(SSL)项下拉选择始终信任，如图
将证书安装到手机上
1. 方法1，步骤如下：
  1. Help->SSL Proxying->Install Charles Root Certificate …Browser，然后弹出如下弹窗：
  2. 在手机已经连接代理的情况下，在浏览器中输入chls.pro/ssl，然后将证书下载到本地，再进行安装。
2. 方法2，步骤如下：
  1. Help->SSL Proxying->Save Charles Root Certificate… 将证书下载到本地，再将证书传输到手机上，再进行安装。
