Java發送https請求

1、前文：通過webService發送https請求，有兩種版本，一種是攜帶證書驗證（比較麻煩），另外一種就是直接忽略證書，本文提供的就是第二種（本人已測試過）

 

2、最簡易代碼：

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;

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();
            //忽略證書驗證--Begin
            conn.setHostnameVerifier(new TrustAnyHostnameVerifier());
            //忽略證書驗證--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();
            
        }
        
    }
    
    /**

    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Verifier
class TrustAnyHostnameVerifier implements HostnameVerifier {
    public boolean verify(String hostname, SSLSession session) {
        return true;
    }
