java實現https免證書認證

 

解決方法：

1.下載兩個包，httpclient-4.2.jar和httpcore-4.2.jar，複製以下程式碼就可使用。

2.呼叫類程式碼：

String httpOrgCreateTest = "https://url";

   Map<String,Object> createMap = new HashMap<String,Object>();

createMap.put("name","8888888");

createMap.put("num","11111");

createMap.put("array",list.toArray());

    String message = JSON.toJSONString(createMap);

    String result = HttpRequest.sendPost(httpOrgCreateTest, message);

3.HttpRequest類

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.PrintWriter;

import java.net.URL;

import javax.net.ssl.HttpsURLConnection;

import javax.net.ssl.SSLContext;

import javax.net.ssl.SSLSocketFactory;

import javax.net.ssl.TrustManager;

public class HttpRequest {

 

public static String sendPost(String url, String param) {

PrintWriter out = null;

BufferedReader in = null;

String result = "";

try {

 

// 建立SSLContext物件，並使用我們指定的信任管理器初始化

TrustManager[] tm = { new MyX509TrustManager() };

SSLContext sslContext = SSLContext.getInstance("SSL");

sslContext.init(null, tm, new java.security.SecureRandom());

 

// 從上述SSLContext物件中得到SSLSocketFactory物件

SSLSocketFactory ssf = sslContext.getSocketFactory();

 

// 開啟和URL之間的連線

//URL realUrl = new URL(url);

URL realUrl= new URL(null, url, new sun.net.www.protocol.https.Handler());

HttpsURLConnection conn = (HttpsURLConnection) realUrl.openConnection();

conn.setSSLSocketFactory(ssf);

 

// 設定通用的請求屬性

conn.setRequestProperty("accept", "*/*");

conn.setRequestProperty("connection", "Keep-Alive");

conn.setRequestProperty("content-Type", "application/json");

conn.setRequestProperty("user-agent",

"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");

// 傳送POST請求必須設定如下兩行

conn.setDoOutput(true);

conn.setDoInput(true);

// 獲取URLConnection物件對應的輸出流

out = new PrintWriter(conn.getOutputStream());

// 傳送請求引數

 

out.print(param);

// flush輸出流的緩衝

out.flush();

// 定義BufferedReader輸入流來讀取URL的響應

in = new BufferedReader(

new InputStreamReader(conn.getInputStream()));

String line;

while ((line = in.readLine()) != null) {

result += line;

}

} catch (Exception e) {

System.out.println("傳送 POST 請求出現異常！"+e);

e.printStackTrace();

}

//使用finally塊來關閉輸出流、輸入流

finally{

try{

if(out!=null){

out.close();

}

if(in!=null){

in.close();

}

}

catch(IOException ex){

ex.printStackTrace();

}

}

return result;

}

}

 

4.MyX509TrustManager類

import java.security.cert.CertificateException;

import java.security.cert.X509Certificate;

import javax.net.ssl.X509TrustManager;

public class MyX509TrustManager implements X509TrustManager{

@Override

public void checkClientTrusted(X509Certificate[] chain, String authType) throws

CertificateException {

 

}

@Override

public void checkServerTrusted(X509Certificate[] chain, String authType) throws

CertificateException {

 

}

@Override

public X509Certificate[] getAcceptedIssuers() {

return null;

}

}
