1、前文：通过webService发送https请求，有两种版本，一种是携带证书验证（比较麻烦），另外一种就是直接忽略证书，本文提供的就是第二种（本人已测试过）
2、最简易代码：
import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.OutputStream;import java.io.Reader;import java.net.MalformedURLException;import java.net.URL;import java.text.SimpleDateFormat;import javax.net.ssl.HostnameVerifier;import javax.net.ssl.HttpsURLConnection;import javax.net.ssl.SSLSession;@SuppressWarnings("all")public class TestAPI_https { public static void main(String args[]) throws Exception { new TestAPI_https().TestRiQingAPI_SaleOrder(); } public static void TestRiQingAPI_SaleOrder() throws Exception { String postData = getJson(); //String url = "https://*****"; String url = "https://*****"; HttpsURLConnection conn = null; OutputStream out = null; String rsp = null; byte[] byteArray = postData.getBytes("utf-8"); try { URL uri = new URL(url); conn = (HttpsURLConnection) uri.openConnection(); //忽略证书验证--Begin conn.setHostnameVerifier(new TrustAnyHostnameVerifier()); //忽略证书验证--End conn.setRequestMethod("POST"); conn.setDoInput(true); conn.setDoOutput(true); conn.setRequestProperty("Host", uri.getHost()); conn.setRequestProperty("Content-Type", "application/json"); out = conn.getOutputStream(); out.write(byteArray); out.close(); if(conn.getResponseCode()==200) { rsp = getStreamAsString(conn.getInputStream(), "utf-8"); }else { rsp = getStreamAsString(conn.getErrorStream(), "utf-8"); } System.out.println(rsp); } catch (Exception e) { if(null!=out) out.close(); e.printStackTrace(); } } /** * getJson * */ private static String getJson() { return "{" + "\"name\"" + ":" + "\"robo_blogs_zh123\"" + "}"; } private static String getStreamAsString(InputStream stream, String charset) throws IOException { try { Reader reader = new InputStreamReader(stream, charset); StringBuilder response = new StringBuilder(); final char[] buff = new char[1024]; int read = 0; while ((read = reader.read(buff)) > 0) { response.append(buff, 0, read); } return response.toString(); } finally { if (stream != null) { stream.close(); } } }}//定制Verifierclass TrustAnyHostnameVerifier implements HostnameVerifier { public boolean verify(String hostname, SSLSession session) { return true; }}
