Example 30 with CharArrayReader

use of java.io.CharArrayReader in project leopard by tanhaichao.

the class tls_sigature method CheckTLSSignature.

/**
 * @brief 校验 tls 票据
 * @param urlSig 返回 tls 票据
 * @param strAppid3rd 填写与 sdkAppid 一致的字符串形式的值
 * @param skdAppid 应的 appid
 * @param identifier 用户 id
 * @param accountType 创建应用后在配置页面上展示的 acctype
 * @param publicKey 用于校验 tls 票据的公钥内容，但是需要先将公钥文件转换为 java 原生 api 使用的格式，下面是推荐的命令
 *         openssl pkcs8 -topk8 -in ec_key.pem -outform PEM -out p8_priv.pem -nocrypt
 * @return 如果出错 CheckTLSSignatureResult 中的 verifyResult 为 false，错误信息在 errMsg，校验成功为 true
 * @throws DataFormatException
