我可以连接到http url但是什么时候 服务器移动到https，我的代码不起作用。 任何人都可以帮助我以最小的变化进行更正。
我正在使用以下经理文件（开源代码） 做各种http请求（上传文件， 下载文件或简单的身份验证）。
我也尝试过使用httpsUrlConnection，但我想， 我错过了那里的东西。请提出建议...

在HTTPS连接中禁用证书验证的示例代码 http://exampledepot.com/egs/javax.net.ssl/TrustAll.html
答案 1 :(得分：0)
在java prog
中使用此代码 try {
logger.info("Importing the Https certificate..");
/* ----------- Importing the Https certificate -----------*/
TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
@Override
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
@Override
public void checkClientTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
}
@Override
public void checkServerTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
}
}
};
try {
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
System.out.println("Exception" + e);
}
HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String string, SSLSession ssls) {
return true;
}
});
并查看this link你必须在server.xml中进行更改
