Android通过http协议POST传输方式
在这里做个简单是总结和实现:-----------------------------------------------------------------------------------------------------------------------
Android通过http协议POST传输方式如下:
方式一:HttpPost(import org.apache.http.client.methods.HttpPost)
代码如下:
private Button button1,button2,button3;
private TextView textView1;
button1.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
//URLַ
// String uriAPI = "http://www.dubblogs.cc:8751/Android/Test/API/Post/index.php";
String uriAPI = "http://172.20.0.206:8082//TestServelt/login.do";
/*建立HTTP Post连线*/
HttpPost httpRequest =new HttpPost(uriAPI);
//Post运作传送变数必须用NameValuePair[]阵列储存
//传参数 服务端获取的方法为request.getParameter("name")
List <NameValuePair> params=new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("name","this is post"));
try{
//发出HTTP request
httpRequest.setEntity(new UrlEncodedFormEntity(params,HTTP.UTF_8));
//取得HTTP response
HttpResponse httpResponse=new DefaultHttpClient().execute(httpRequest);
//若状态码为200 ok
if(httpResponse.getStatusLine().getStatusCode()==200){
//取出回应字串
String strResult=EntityUtils.toString(httpResponse.getEntity());
textView1.setText(strResult);
}else{
textView1.setText("Error Response"+httpResponse.getStatusLine().toString());
}
}catch(ClientProtocolException e){
textView1.setText(e.getMessage().toString());
e.printStackTrace();
}catch (UnsupportedEncodingException e) {
textView1.setText(e.getMessage().toString());
e.printStackTrace();
}catch (IOException e) {
textView1.setText(e.getMessage().toString());
e.printStackTrace();
}
} });
方式二:HttpURLConnection、URL(import java.net.HttpURLConnection;import java.net.URL;import java.net.URLEncoder;)
private void httpUrlConnection(){
try{
String pathUrl = "http://172.20.0.206:8082/TestServelt/login.do";
//建立连接
URL url=new URL(pathUrl);
HttpURLConnection httpConn=(HttpURLConnection)url.openConnection();
////设置连接属性
httpConn.setDoOutput(true);//使用 URL 连接进行输出
httpConn.setDoInput(true);//使用 URL 连接进行输入
httpConn.setUseCaches(false);//忽略缓存
httpConn.setRequestMethod("POST");//设置URL请求方法
String requestString = "客服端要以以流方式发送到服务端的数据...";
//设置请求属性
//获得数据字节数据,请求数据流的编码,必须和下面服务器端处理请求流的编码一致
byte[] requestStringBytes = requestString.getBytes(ENCODING_UTF_8);
httpConn.setRequestProperty("Content-length","" + requestStringBytes.length);
httpConn.setRequestProperty("Content-Type","application/octet-stream");
httpConn.setRequestProperty("Connection","Keep-Alive");// 维持长连接
httpConn.setRequestProperty("Charset","UTF-8");
//
String name=URLEncoder.encode("黄武艺","utf-8");
httpConn.setRequestProperty("NAME",name);
//建立输出流,并写入数据
OutputStream outputStream = httpConn.getOutputStream();
outputStream.write(requestStringBytes);
outputStream.close();
//获得响应状态
int responseCode = httpConn.getResponseCode();
if(HttpURLConnection.HTTP_OK == responseCode){//连接成功
//当正确响应时处理数据
StringBuffer sb = new StringBuffer();
String readLine;
BufferedReader responseReader;
//处理响应流,必须与服务器响应流输出的编码一致
responseReader = new BufferedReader(new InputStreamReader(httpConn.getInputStream(),ENCODING_UTF_8));
while ((readLine = responseReader.readLine()) != null) {
sb.append(readLine).append("\n");
}
responseReader.close();
tv.setText(sb.toString());
}
}catch(Exception ex){
ex.printStackTrace();
}
}--

下面有好几种的实现方式:
1。
public Map<String, Object> CreateNote( int albumId, String title, |
02 | String remark) { |
03 | String noteId = "" ; |
04 | Map<String, Object> map = new HashMap<String, Object>(); |
05 | try { |
06 | HttpParams parms = new BasicHttpParams(); |
07 | parms.setParameter( "charset" , HTTP.UTF_8); |
08 | HttpConnectionParams.setConnectionTimeout(parms, 8 * 1000 ); |
09 | HttpConnectionParams.setSoTimeout(parms, 8 * 1000 ); |
10 | HttpClient httpclient = new DefaultHttpClient(parms); |
11 | HttpPost httppost = new HttpPost(ConfigHelper.CreateUri); |
12 | httppost.addHeader( "Authorization" , mToken); |
13 | httppost.addHeader( "Content-Type" , "application/json" ); |
14 | httppost.addHeader( "charset" , HTTP.UTF_8); |
15 |
16 | JSONObject obj = new JSONObject(); |
17 | obj.put( "title" , title); |
18 | obj.put( "categoryId" , mCategoryId); |
19 | obj.put( "sourceUrl" , GetSourceUri()); |
20 |
21 | JSONArray arr = new JSONArray(); |
22 |
23 | arr.put(DateFormat.format( "yyyyMM" ,Calendar.getInstance(Locale.CHINA))); |
24 | obj.put( "tags" , arr); |
25 | obj.put( "content" , remark); |
26 | httppost.setEntity( new StringEntity(obj.toString(), HTTP.UTF_8)); |
27 | HttpResponse response; |
28 | response = httpclient.execute(httppost); |
29 | int code = response.getStatusLine().getStatusCode(); |
30 | if (code == ConstanDefine.ErrorCode.SuccOfHttpStatusCode) { |
31 | String rev = EntityUtils.toString(response.getEntity()); |
32 | obj = new JSONObject(rev); |
33 | noteId = obj.getString( "id" ); |
34 | map.put( "return_code" , "0" ); |
35 | map.put( "content" , |
36 | } |
37 | } catch (Exception e) { |
38 | if (map.containsKey( "return_code" )) { |
39 | map.remove( "return_code" ); |
40 | } |
41 | map.put( "return_code" , "1" ); |
42 | } |
43 | return map; |
44 | } |
public static String post1(String message)
{
String uriAPI = HTTP_PORT ;
HttpPost httpRequest = new HttpPost(uriAPI);
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("input",message));
try {
httpRequest.setEntity(new UrlEncodedFormEntity(params,"UTF-8"));
org.apache.http.HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest);
if (httpResponse.getStatusLine().getStatusCode() == 200) {
String strResult = EntityUtils.toString(httpResponse.getEntity());
return strResult;
}else {
System.out.println(httpResponse.getStatusLine().getStatusCode());
}
}catch (ClientProtocolException e) {
e.printStackTrace();
}catch (UnsupportedEncodingException e) {
e.printStackTrace();
}catch (IOException e) {
e.printStackTrace();
}
return null;
}
