URL oauth = new URL(URL);
URLConnection oauth_connection = oauth.openConnection();

BufferedReader in = new BufferedReader(new InputStreamReader(
            oauth_connection.getInputStream()));

String inputLine = "";

String line;

//System.out.println(in.readLine());
while((line = in.readLine()) != null)
    inputLine += line;

in.close();

BufferedReader在该行引发异常：

您可能拥有自签名证书或链式证书，其中链的某些部分不受信任。

您可以将证书导入您的信任库，请参阅数字证书：如何将 .cer 文件导入到 .truststore 文件中？

或者您可以忽略此问题，如在 Java 中请求 URL 时忽略证书错误

如果您的客户端是用 Java 编写的，那么您需要做的就是将服务器证书添加到受信任的 Java 密钥库中。
