Android Series: GET, POST and Multipart POST 请求

如果你的请求要加附件你要加入apache-mime4j-0.6.jar and httpmime-4.0.1.jar 到你建的工程当中

try {
        HttpClient client = new DefaultHttpClient ( ) ;  
        String getURL = "http://www.google.com" ;
        HttpGet get = new HttpGet (getURL ) ;
        HttpResponse responseGet = client. execute (get ) ;  
        HttpEntity resEntityGet = responseGet. getEntity ( ) ;  
        if (resEntityGet != null ) {  
                    //do something with the response
                    Log. i ( "GET RESPONSE",EntityUtils. toString (resEntityGet ) ) ;
                }
} catch ( Exception e ) {
    e. printStackTrace ( ) ;
}

2.

try {
        HttpClient client = new DefaultHttpClient ( ) ;  
        String postURL = "http://somepostaddress.com" ;
        HttpPost post = new HttpPost (postURL ) ;
            List <NameValuePair > params = new ArrayList <NameValuePair > ( ) ;
            params. add ( new BasicNameValuePair ( "user", "kris" ) ) ;
            params. add ( new BasicNameValuePair ( "pass", "xyz" ) ) ;
            UrlEncodedFormEntity ent = new UrlEncodedFormEntity (params,HTTP. UTF_8 ) ;
            post. setEntity (ent ) ;
            HttpResponse responsePOST = client. execute (post ) ;  
            HttpEntity resEntity = responsePOST. getEntity ( ) ;  
            if (resEntity != null ) {    
                Log. i ( "RESPONSE",EntityUtils. toString (resEntity ) ) ;
            }
    } catch ( Exception e ) {
        e. printStackTrace ( ) ;
    }

3.

File file = new File ( "path/to/your/file.txt" ) ;
try {
         HttpClient client = new DefaultHttpClient ( ) ;  
          String postURL = "http://someposturl.com" ;
         HttpPost post = new HttpPost (postURL ) ;
     FileBody bin = new FileBody (file ) ;
     MultipartEntity reqEntity = new MultipartEntity (HttpMultipartMode. BROWSER_COMPATIBLE ) ;  
     reqEntity. addPart ( "myFile", bin ) ;
     post. setEntity (reqEntity ) ;  
     HttpResponse response = client. execute (post ) ;  
     HttpEntity resEntity = response. getEntity ( ) ;  
      if (resEntity != null ) {    
               Log. i ( "RESPONSE",EntityUtils. toString (resEntity ) ) ;
          }
} catch ( Exception e ) {
    e. printStackTrace ( ) ;
}

下面是一个例子

public void executeMultipartPost() throws Exception {
try {
//InputStream is = this.getAssets().open(“main.xml”); //c:/reno.jpg taka prava pot za winse
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost(

postRequest.setEntity(multipartContent);

Log.d(“HTTPKODA”,res.getStatusLine().toString() );

HttpEntity resEntity = res.getEntity();
if (resEntity != null) {
Log.d(“ODGOVOR”,EntityUtils.toString(resEntity));//tole je odgovor
}
httpClient.getConnectionManager().shutdown(); //sprostimo resurse

//res.getEntity().getContent().close(); //ce tole zivo javi napako
} catch (IOException e) {
throw e;
}
