javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certificatio

场景：Java调用PHP接口，代码部署在服务器上后，调用报错，显示PHP服务器那边证书我这边服务器不信任(我猜的)。

异常信息：

- main方法跑完上面代码生成一个名叫jssecacerts的文件，将这个文件copy到服务器上面，我copy到opt文件夹下面了。
- 在调用PHP接口之前加上下面的代码。

System.setProperty("javax.net.ssl.trustStore", "/opt/jssecacerts");

- 再调接口就没问题了。注：PHP接口返回的字符串可能会自带""，多出来的双引号得处理下去掉双引号：str1 = str.replace("\"","").replace("\"","");
