Android Http Example

public class Main extends Activity {
    
    private Button btnGet;
    private Button btnPost;
    private EditText etName;
    private EditText etPwd;

    @Override

                try {
                    HttpResponse response = new DefaultHttpClient().execute(request);
                    if(response.getStatusLine().getStatusCode() == 200){
                        String result = EntityUtils.toString(response.getEntity());
                        Toast.makeText(Main.this, result, Toast.LENGTH_LONG).show();

                }
            }
        });
    }
}

在xml页面加入网络权限：

<uses-permission android:name="android.permission.INTERNET" />

服务器端部分代码：

    @Override  
    @SuppressWarnings("rawtypes")  
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {  
        boolean isMultipart = ServletFileUpload.isMultipartContent(request);  
        if (isMultipart) {  
            FileItemFactory factory = new DiskFileItemFactory();  
            ServletFileUpload upload = new ServletFileUpload(factory);  
            try {  
                List items = upload.parseRequest(request);  
                Iterator iter = items.iterator();  
                while (iter.hasNext()) {  
                    FileItem item = (FileItem) iter.next();  
                    if (item.isFormField()) {  
                        //普通文本信息处理   
                        String paramName = item.getFieldName();  
                        String paramValue = item.getString();  
                        System.out.println(paramName + ":" + paramValue);  
                    } else {  
                        //上传文件信息处理   
                        String fileName = item.getName();  
                        byte[] data = item.get();  
                        String filePath = getServletContext().getRealPath("/files") + "/" + fileName;  
                        FileOutputStream fos = new FileOutputStream(filePath);  
                        fos.write(data);  
                        fos.close();  
                    }  
                }  
            } catch (FileUploadException e) {  
                e.printStackTrace();  
            }  
        }  
        response.getWriter().write("UPLOAD_SUCCESS");  
    }  
}
