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"
, rev);
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
}
2。
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;
}
