我部署了一个REST应用程序Web服务，在客户端，在构建URL之后，我正在建立HTTP URL连接＆amp;打开Buffered Reader将数据流发送到服务器端。
以下是代码片段。
SSLContext sc = SSLContext.getInstance("SSL");
javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(
new javax.net.ssl.HostnameVerifier(){
public boolean verify(String hostname,
javax.net.ssl.SSLSession sslSession) {
return true;
}
});
HttpURLConnection conn = (HttpURLConnection) tnprestapplicationURL.openConnection();
String USER_AGENT = "Mozilla/5.0";
conn.setRequestMethod("GET");
conn.setRequestProperty("Accept", "application/json");
BufferedReader br = new BufferedReader(new
InputStreamReader((conn.getInputStream())));
我在SSL连接时添加了证书。我不知道这个概念。下面是我添加的一段代码，以摆脱异常，但我仍面临异常。任何人都可以帮忙吗？
