// 直接获取信息

void DirectInfo() throws IOException {

URL url = new URL(SRC);

HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();

InputStreamReader inStreamReader = new InputStreamReader(httpConn

.getInputStream());

BufferedReader bufReader = new BufferedReader(inStreamReader);

String line = "";

String Date = "OK";

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

Date += line + "\n";

}

edit1.setText(Date);

}

// get方式获取信息

void getInfo() throws IOException {

// 将上面使用的方法直接修改一下即可。

URL url = new URL(SRC+"/default.aspx?NAME="

+ URLEncoder.encode("abc", "utf-8"));

HttpURLConnection httpconn = (HttpURLConnection) url.openConnection();

InputStreamReader inputReader = new InputStreamReader(httpconn

.getInputStream());

BufferedReader bufReader = new BufferedReader(inputReader);

String line = "";

String Date = "";

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

Date += line;

}

edit1.setText(Date);

}

// Post方式获取信息

void postInfo() throws MalformedURLException, IOException {

// Post 方法比Get方法需要设置的参数更多

HttpURLConnection httpconn = (HttpURLConnection) new URL(SRC)

.openConnection();

// post 方式,输入输出需要设置为true

httpconn.setDoInput(true);

httpconn.setDoOutput(true);

httpconn.setRequestMethod("POST"); // 设置为Post方式,默认为get方式

httpconn.setUseCaches(false); // 不使用缓存

httpconn.setInstanceFollowRedirects(true); // 重定向

httpconn.setRequestProperty("Content-type",

"Application/x-www-form-urlencoded"); // 设置连接 的Content-type类型为:

// application/x-www-form-urlencoded

httpconn.connect(); //连接

DataOutputStream out = new DataOutputStream(httpconn.getOutputStream()); //声明数据写入流

String NAME= "NAME="+URLEncoder.encode("fly_binbin", "UTF-8");

String PWD="PWD="+URLEncoder.encode("123456","UTF-8");

String content = NAME+"&"+PWD;

out.writeBytes(content);

out.flush();

out.close();

BufferedReader reader = new BufferedReader(new InputStreamReader(httpconn.getInputStream()));

String line = "";

String resultDate = "";

while((line=reader.readLine())!=null)

{

resultDate += line;

}

edit1.setText(resultDate);

}

// post方式第二种

private static boolean sendPostRequest(String path, Map params, String encoding) throws Exception{ // method=save&name=liming&timelength=78 StringBuilder sb = new StringBuilder(""); if(params!=null && !params.isEmpty()){ for(Map.Entry entry : params.entrySet()){ sb.append(entry.getKey()).append('=') .append(URLEncoder.encode(entry.getValue(), encoding)).append('&'); } sb.deleteCharAt(sb.length() - 1); } byte[] data = sb.toString().getBytes();//得到实体数据 URL url = new URL(path); HttpURLConnection conn = (HttpURLConnection)url.openConnection(); conn.setRequestMethod("POST"); conn.setConnectTimeout(5*1000); conn.setDoOutput(true);//能过post方式提交数据,必须要允许输出 conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); conn.setRequestProperty("Content-Length", String.valueOf(data.length)); OutputStream outStream = conn.getOutputStream(); outStream.write(data); outStream.flush(); outStream.close(); if(conn.getResponseCode()==200){ return true; } return false; }
