Java發(fā)送https請求代碼實例

這篇文章主要介紹了Java發(fā)送https請求代碼實例,文中通過示例代碼介紹的非常詳細，對大家的學習或者工作具有一定的參考學習價值,需要的朋友可以參考下

1、前文：通過webService發(fā)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;

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