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;

}
