网上找了很多种请求https协议的方法,差不多都是以下的形式:
public class HttpsUtil{
private static class TrustAnyTrustManager implements X509TrustManager {
public void checkClientTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
}
public X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[] {};
}
}
private static class TrustAnyHostnameVerifier implements HostnameVerifier {
public boolean verify(String hostname, SSLSession session) {
return true;
}
}
/**
* post方式请求服务器(https协议)
* @param url
* 请求地址
* @param content
* 参数
* @param charset
* 编码
* @return
* @throws NoSuchAlgorithmException
* @throws KeyManagementException
* @throws IOException
*/
public static byte[] post(String url, String content, String charset)
throws NoSuchAlgorithmException, KeyManagementException,
IOException {
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, new TrustManager[] { new TrustAnyTrustManager() },
new java.security.SecureRandom());
URL console = new URL(url);
HttpsURLConnection conn = (HttpsURLConnection) console.openConnection();
conn.setSSLSocketFactory(sc.getSocketFactory());
conn.setHostnameVerifier(new TrustAnyHostnameVerifier());
conn.connect();
DataOutputStream out = new DataOutputStream(conn.getOutputStream());
out.write(content.getBytes(charset));
// 刷新、关闭
out.flush();
out.close();
InputStream is = conn.getInputStream();
if (is != null) {
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
int len = 0;
while ((len = is.read(buffer)) != -1) {
outStream.write(buffer, 0, len);
}
is.close();
return outStream.toByteArray();
}
return null;
}
}
但是,我用这种方法访问的时候,还是不行会报错:
[16:38:19.303] java.lang.IllegalArgumentException: protocol = https host = null
哪位大神,有木有好的方法啊。
java https
------解决方案--------------------
试试SSLContext sc= SSLContext.getInstance("SSL", "SunJSSE");
