还是接上篇

修改了一些VideoManageAction

package com.su.action;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.text.SimpleDateFormat;
import java.util.Date;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;
import com.su.action.util.StreamTool;



public class VideoManageAction extends ActionSupport {
	private String title;
	private String timelength;
	private File myFile;
    private String myFileFileName;
    public String getMethod() {
		return method;
	}

	public void setMethod(String method) {
		this.method = method;
	}

	private String method;
    public File getMyFile() {
		return myFile;
	}

	public void setMyFile(File myFile) {
		this.myFile = myFile;
	}

	public String getTitle() {
		return title;
	}

	public void setTitle(String title) {
		this.title = title;
	}

	public String getTimelength() {
		return timelength;
	}

	public void setTimelength(String timelength) {
		this.timelength = timelength;
	}

	public void setMyFileFileName(String myFileFileName) {
		this.myFileFileName = myFileFileName;
	}

	

	public String getMyFileFileName() {
		return myFileFileName;
	}

	public String execute() throws Exception {
		if (method.equals("getXml")) {
			InputStream inStream = ServletActionContext.getRequest().getInputStream();
			byte[] data = StreamTool.readInputStream(inStream);
			String xml = new String(data, "UTF-8");
			System.out.println("11111111111111111111");
			System.out.println(xml);
		}
		if (myFile!=null) {
		
		InputStream is = new FileInputStream(myFile);
		String uploadPath = ServletActionContext.getServletContext()
				.getRealPath("/upload");
		File file = new File(uploadPath);
		
		if (!file.exists()) {
			file.mkdir();
			
			
		}
		File toFile = new File(uploadPath, this.getMyFileFileName());

		OutputStream os = new FileOutputStream(toFile);

		byte[] buffer = new byte[1024];

		int length = 0;

		while ((length = is.read(buffer)) > 0) {
			os.write(buffer, 0, length);
		}
		
		is.close();
		os.close();
		}
		System.out.println(this.getTimelength()+"\n"+this.getTitle()+"\n");
		return SUCCESS;

	}
}

这次使用TestCase 用的时候加如activity吧

package cn.itcast.uploaddata;

import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;

import cn.itcast.net.HttpRequest;
import android.test.AndroidTestCase;

public class HttpRequestTest extends AndroidTestCase {
	private static final String TAG = "HttpRequestTest";
	
	public void testSendXMLRequest() throws Throwable{
		String xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><persons><person id=\"23\"><name>liming</name><age>30</age></person></persons>";
		HttpRequest.sendXML("http://10.1.27.35:8080/VideoWeb2/upload.action?method=getXml", xml);
	}

	public void testSendGetRequest() throws Throwable{
		//?method=save&title=xxxx&timelength=90
		Map<String, String> params = new HashMap<String, String>();
		//params.put("method", "save");
		params.put("title", "liming");
		params.put("timelength", "80");
		HttpRequest.sendGetRequest("http://10.1.27.35:8080/VideoWeb2/upload.action", params, "UTF-8");
	}
	
	public void testSendPostRequest() throws Throwable{
		Map<String, String> params = new HashMap<String, String>();
		//params.put("method", "save");
		params.put("title", "中国");
		params.put("timelength", "80");
		
		HttpRequest.sendPostRequest("http://10.1.27.35:8080/VideoWeb2/upload.action", params, "UTF-8");
	}
	
	public void testSendRequestFromHttpClient() throws Throwable{
		Map<String, String> params = new HashMap<String, String>();
		//params.put("method", "save");
		params.put("title", "传智播客");
		params.put("timelength", "80");
		
		boolean result = HttpRequest.sendRequestFromHttpClient("http://10.1.27.35:8080/VideoWeb2/upload.action", params, "UTF-8");
		Log.i("HttRequestTest", ""+ result);
	}
}
