问题描述
尝试向http服务器发送请求时出现以下异常:
I got the following exception when try to post a request to a http server:
这里是我使用的代码
URL url = new URL(
"https://www.abc.com");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(conn.getOutputStream());
// wr.writeBytes(params);
wr.flush();
wr.close();
BufferedReader br = new BufferedReader(new InputStreamReader(
conn.getInputStream()));
String line = null;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
以下是例外情况:

服务器不属于我。有没有办法忽略这个异常?
The server is not owned by me. Is there a way to ignore this exception?
推荐答案
如果你想一起忽略证书,此处:
If you want to ignore the certificate all together then take a look at the answer here: Ignore self-signed ssl cert using Jersey Client
虽然这会使您的应用程式容易受到中间人攻击。
Although this will make your app vulnerable to man-in-the-middle attacks.
该证书作为您的java存储作为可信证书。
本网站可能是有帮助的。
Or, try adding the cert to your java store as a trusted cert.This site may be helpful.http://blog.icodejava.com/tag/get-public-key-of-ssl-certificate-in-java/
这是另一个线程,显示如何添加证书到您的商店。
Here's another thread showing how to add a cert to your store.Java SSL connect, add server cert to keystore programatically
关键是:
KeyStore.Entry newEntry = new KeyStore.TrustedCertificateEntry(someCert);
ks.setEntry("someAlias", newEntry, null);
