摘要：程序抛出UncheckedIOException，原因是未找到证书文件apiclient_key.pem。该异常由FileNotFoundException触发，表明系统在.\wepay\路径下无法定位到指定的PEM密钥文件。可能由于文件路径错误、权限不足或文件缺失导致。需检查路径配置、文件是否存在及访问权限以确保程序正常运行。（98字）

The method encode(String, String) in the type URLEncoder is not applicable for the arguments (String, Charset)

The method of(String[]) is undefined for the type List

Null type safety: The expression of type 'String' needs unchecked conversion to conform to '@NonNull Object'

Null pointer access: The variable list can only be null at this location

Access restriction: The type 'BASE64Decoder' is not API (restriction on required library 'D:\Java\jdk1.8.0_341\jre\lib\rt.jar')

Unlikely argument type for equals(): String seems to be unrelated to Class<capture#2-of ?>@SuppressWarnings("unlikely-arg-type")
