如何在Java中发出HTTPS发布请求? [英] How to make HTTPS post request in Java?

问题描述

我正在尝试发出HTTPS发布请求.

I'm trying to make a HTTPS post request.

String url = "https://myhttpsurl.com"
URL myurl = new URL(url);
HttpsURLConnection con = (HttpsURLConnection) myurl.openConnection();
con.setRequestMethod("POST");
String query = "confirmation_number=" + URLEncoder.encode(confNumber, "UTF-8");
con.setRequestProperty("Content-length",String.valueOf(query.length()));
con.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
con.setDoOutput(true);
con.setDoInput(true);

DataOutputStream output = new DataOutputStream(con.getOutputStream());
output.writeBytes(query);

output.close();
System.out.println("Resp Code:"+con.getResponseCode());

我遇到以下错误:

请提出导致错误的原因

推荐答案

Java无法在https服务器上验证SSL证书的有效性.它可以是自签名的，也可以由Java运行时不知道的证书颁发机构签名.

Java is not able to verify the validity of the SSL certificate on the https server. It is either self-signed or signed by a certificate authority not known to the Java runtime.

您的选择是通过将证书添加到信任库(证书)来手动信任证书，或者对证书进行签名.我不建议您完全禁用SSL证书验证，因为您可能会承受意料之外的后果.

Your options are to manually trust the certificate by adding it to the truststore (cacerts), or to have your certificate signed. I don't recommend disabling the SSL certificate validation completely, as you might open yourself to unexpected consequences.
