java使用Post方式发送https请求的方法,直接可以用


                踩过无数坑之后,成功的方案,主要在设置Content-type  application/x-www-form-urlencoded这里,之前没设置,一直数据不通过,不过好了现在OK了

 

   

URL reqURL = new URL(url); //创建URL对象
HttpURLConnection httpsConn = (HttpURLConnection)reqURL.openConnection();
httpsConn.setDoOutput(true);
httpsConn.setRequestMethod("POST");
httpsConn.setRequestProperty("Content-type", "application/x-www-form-urlencoded");
httpsConn.setRequestProperty("Accept-Charset", "utf-8");
httpsConn.setRequestProperty("contentType", "utf-8");
httpsConn.setRequestProperty("Content-Length", stringA.length()
+ "");
OutputStreamWriter out = new OutputStreamWriter(httpsConn.getOutputStream(),"utf-8");
out.write(stringA.toString());
out.flush();
out.close();
//取得该连接的输入流,以读取响应内容
InputStreamReader insr = new InputStreamReader(httpsConn.getInputStream(),"utf-8");


//读取服务器的响应内容并显示
String result = "";
int respInt = insr.read();
while(respInt != -1){
result += (char)respInt;
respInt = insr.read();
}
