使用httpurlconnection 把数据提交到服务器

get方式提交

1.@Override
2.    public void onClick(View arg0) {
3.        new Thread(){
4.            public void run() {
5.                String username = et_username.getText().toString();
6.                String pwd = et_pwd.getText().toString();
7.                //get方式提交 参数放到url的后面
8.                
9.                try {
10.                    //如果提交的参数包含中文 必须先进行url编码 然后在提交到服务端
11.                    //URLEncoder.encode(要提交的内容,用到的字符集);
12.                    String tempUrl = path+"?username="+URLEncoder.encode(username, "utf-8")+"&password="+URLEncoder.encode(pwd, "utf-8");
13.                    URL url = new URL(tempUrl);
14.                    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
15.                    connection.setRequestMethod("GET");
16.                    connection.setConnectTimeout(10000);
17.                    int code = connection.getResponseCode();
18.                    if(code==200){
19.                        InputStream inputStream = connection.getInputStream();
20.                        String result = Utils.getStringFromStream(inputStream);
21.                        showToast(result);
22.                    }
23.                } catch (Exception e) {
24.                    // TODO Auto-generated catch block
25.                    e.printStackTrace();
26.                }
27.            };
28.        }.start();

通过post方式提交参数 需要手动添加请求头 打开输出流 通过输出流把请求体的内容写到服务端

connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

  //告诉服务器,传递的数据长度

connection.setRequestProperty("Content-Length", String.valueOf(params.length())); 

1.new Thread(){
2.                public void run() {
3.                    String username = et_username.getText().toString();
4.                    String pwd = et_pwd.getText().toString();
5.                    try {
6.                        //由于传递的内容是urlencoded 参数的中文内容需要进行url编码
7.                        String params = "username="+URLEncoder.encode(username,"utf-8")+"&password="+URLEncoder.encode(pwd,"utf-8");
8.                        URL url = new URL(path);
9.                        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
10.                        connection.setRequestMethod("POST");
11.                        connection.setConnectTimeout(10000);
12.                        //设置跟post请求相关的请求头
13.                        //告诉服务器 要传递的数据类型
14.                        connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
15.                        //告诉服务器,传递的数据长度
16.                        connection.setRequestProperty("Content-Length", String.valueOf(params.length()));
17.                        //打开输出流
18.                        connection.setDoOutput(true);
19.                        //通过流把请求体写到服务端
20.                        connection.getOutputStream().write(params.getBytes());
21.                        int code = connection.getResponseCode();
22.                        if(code==200){
23.                            InputStream inputStream = connection.getInputStream();
24.                            String rusult = Utils.getStringFromStream(inputStream);
25.                            showToast(rusult);
26.                        }
27.                    } catch (Exception e) {
28.                        // TODO Auto-generated catch block
29.                        e.printStackTrace();
30.                    }
31.                };
32.            }.start();
