Struts2+Android 多种方式向服务器发送信息

还是接上篇 Struts2+Android 实现信息,文件上传功能

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);
}
}
