這篇文章將為大家詳細(xì)講解有關(guān)Android應(yīng)用中怎么將文件上傳到服務(wù)器,文章內(nèi)容質(zhì)量較高,因此小編分享給大家做個(gè)參考,希望大家閱讀完這篇文章后對相關(guān)知識有一定的了解。
創(chuàng)新互聯(lián)建站主營田家庵網(wǎng)站建設(shè)的網(wǎng)絡(luò)公司,主營網(wǎng)站建設(shè)方案,手機(jī)APP定制開發(fā),田家庵h5微信小程序定制開發(fā)搭建,田家庵網(wǎng)站營銷推廣歡迎田家庵等地區(qū)企業(yè)咨詢
1)、新建一個(gè)Android項(xiàng)目命名為androidUpload,目錄結(jié)構(gòu)如下:
2)、新建FormFile類,用來封裝文件信息
package com.ljq.utils;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;
/**
* 上傳文件
*/
public class FormFile {
/* 上傳文件的數(shù)據(jù) */
private byte[] data;
private InputStream inStream;
private File file;
/* 文件名稱 */
private String filname;
/* 請求參數(shù)名稱*/
private String parameterName;
/* 內(nèi)容類型 */
private String contentType = "application/octet-stream";
public FormFile(String filname, byte[] data, String parameterName, String contentType) {
this.data = data;
this.filname = filname;
this.parameterName = parameterName;
if(contentType!=null) this.contentType = contentType;
}
public FormFile(String filname, File file, String parameterName, String contentType) {
this.filname = filname;
this.parameterName = parameterName;
this.file = file;
try {
this.inStream = new FileInputStream(file);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
if(contentType!=null) this.contentType = contentType;
}
public File getFile() {
return file;
}
public InputStream getInStream() {
return inStream;
}
public byte[] getData() {
return data;
}
public String getFilname() {
return filname;
}
public void setFilname(String filname) {
this.filname = filname;
}
public String getParameterName() {
return parameterName;
}
public void setParameterName(String parameterName) {
this.parameterName = parameterName;
}
public String getContentType() {
return contentType;
}
public void setContentType(String contentType) {
this.contentType = contentType;
}
}
3)、新建SocketHttpRequester類,封裝上傳文件到服務(wù)器代碼
package com.ljq.utils;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.InetAddress;
import java.net.Socket;
import java.net.URL;
import java.util.Map;
/**
* 上傳文件到服務(wù)器
*
* @author Administrator
*
*/
public class SocketHttpRequester {
/**
* 直接通過HTTP協(xié)議提交數(shù)據(jù)到服務(wù)器,實(shí)現(xiàn)如下面表單提交功能:
*
* @param path 上傳路徑(注:避免使用localhost或127.0.0.1這樣的路徑測試,因?yàn)樗鼤赶蚴謾C(jī)模擬器,你可以使用http://www.iteye.cn或http://192.168.1.101:8083這樣的路徑測試)
* @param params 請求參數(shù) key為參數(shù)名,value為參數(shù)值
* @param file 上傳文件
*/
public static boolean post(String path, Map
params, FormFile[] files) throws Exception{
final String BOUNDARY = "---------------------------7da2137580612"; //數(shù)據(jù)分隔線
final String endline = "--" + BOUNDARY + "--\r\n";//數(shù)據(jù)結(jié)束標(biāo)志
int fileDataLength = 0;
for(FormFile uploadFile : files){//得到文件類型數(shù)據(jù)的總長度
StringBuilder fileExplain = new StringBuilder();
fileExplain.append("--");
fileExplain.append(BOUNDARY);
fileExplain.append("\r\n");
fileExplain.append("Content-Disposition: form-data;name=\""+ uploadFile.getParameterName()+"\";filename=\""+ uploadFile.getFilname() + "\"\r\n");
fileExplain.append("Content-Type: "+ uploadFile.getContentType()+"\r\n\r\n");
fileExplain.append("\r\n");
fileDataLength += fileExplain.length();
if(uploadFile.getInStream()!=null){
fileDataLength += uploadFile.getFile().length();
}else{
fileDataLength += uploadFile.getData().length;
}
}
StringBuilder textEntity = new StringBuilder();
for (Map.Entry entry : params.entrySet()) {//構(gòu)造文本類型參數(shù)的實(shí)體數(shù)據(jù)
textEntity.append("--");
textEntity.append(BOUNDARY);
textEntity.append("\r\n");
textEntity.append("Content-Disposition: form-data; name=\""+ entry.getKey() + "\"\r\n\r\n");
textEntity.append(entry.getValue());
textEntity.append("\r\n");
}
//計(jì)算傳輸給服務(wù)器的實(shí)體數(shù)據(jù)總長度
int dataLength = textEntity.toString().getBytes().length + fileDataLength + endline.getBytes().length;
URL url = new URL(path);
int port = url.getPort()==-1 ? 80 : url.getPort();
Socket socket = new Socket(InetAddress.getByName(url.getHost()), port);
OutputStream outStream = socket.getOutputStream();
//下面完成HTTP請求頭的發(fā)送
String requestmethod = "POST "+ url.getPath()+" HTTP/1.1\r\n";
outStream.write(requestmethod.getBytes());
String accept = "Accept: image/gif, image/jpeg, image/pjpeg, image/pjpeg, application/x-shockwave-flash, application/xaml+xml, application/vnd.ms-xpsdocument, application/x-ms-xbap, application/x-ms-application, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*\r\n";
outStream.write(accept.getBytes());
String language = "Accept-Language: zh-CN\r\n";
outStream.write(language.getBytes());
String contenttype = "Content-Type: multipart/form-data; boundary="+ BOUNDARY+ "\r\n";
outStream.write(contenttype.getBytes());
String contentlength = "Content-Length: "+ dataLength + "\r\n";
outStream.write(contentlength.getBytes());
String alive = "Connection: Keep-Alive\r\n";
outStream.write(alive.getBytes());
String host = "Host: "+ url.getHost() +":"+ port +"\r\n";
outStream.write(host.getBytes());
//寫完HTTP請求頭后根據(jù)HTTP協(xié)議再寫一個(gè)回車換行
outStream.write("\r\n".getBytes());
//把所有文本類型的實(shí)體數(shù)據(jù)發(fā)送出來
outStream.write(textEntity.toString().getBytes());
//把所有文件類型的實(shí)體數(shù)據(jù)發(fā)送出來
for(FormFile uploadFile : files){
StringBuilder fileEntity = new StringBuilder();
fileEntity.append("--");
fileEntity.append(BOUNDARY);
fileEntity.append("\r\n");
fileEntity.append("Content-Disposition: form-data;name=\""+ uploadFile.getParameterName()+"\";filename=\""+ uploadFile.getFilname() + "\"\r\n");
fileEntity.append("Content-Type: "+ uploadFile.getContentType()+"\r\n\r\n");
outStream.write(fileEntity.toString().getBytes());
if(uploadFile.getInStream()!=null){
byte[] buffer = new byte[1024];
int len = 0;
while((len = uploadFile.getInStream().read(buffer, 0, 1024))!=-1){
outStream.write(buffer, 0, len);
}
uploadFile.getInStream().close();
}else{
outStream.write(uploadFile.getData(), 0, uploadFile.getData().length);
}
outStream.write("\r\n".getBytes());
}
//下面發(fā)送數(shù)據(jù)結(jié)束標(biāo)志,表示數(shù)據(jù)已經(jīng)結(jié)束
outStream.write(endline.getBytes());
BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
if(reader.readLine().indexOf("200")==-1){//讀取web服務(wù)器返回的數(shù)據(jù),判斷請求碼是否為200,如果不是200,代表請求失敗
return false;
}
outStream.flush();
outStream.close();
reader.close();
socket.close();
return true;
}
/**

* @param file 上傳文件
*/
public static boolean post(String path, Map params, FormFile file) throws Exception{
return post(path, params, new FormFile[]{file});
}
}4)、新建MainActivity類,實(shí)現(xiàn)每隔5秒上傳一次
package com.ljq.activity;
import java.io.File;
import java.util.HashMap;
import java.util.Map;
import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
import android.os.Handler;
import android.util.Log;
import com.ljq.utils.FormFile;
import com.ljq.utils.SocketHttpRequester;
public class MainActivity extends Activity {
private File file;
private Handler handler;
private static final String TAG="MainActivity";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Log.i(TAG, "onCreate");
file = new File(Environment.getExternalStorageDirectory(), "123.rmvb");
Log.i(TAG, "照片文件是否存在:"+file);
handler=new Handler();
handler.post(runnable);
}
Runnable runnable=new Runnable() {
public void run() {
Log.i(TAG, "runnable run");
uploadFile(file);
handler.postDelayed(runnable, 5000);
}
};
/**
* 上傳圖片到服務(wù)器
*
* @param imageFile 包含路徑
*/
public void uploadFile(File imageFile) {
Log.i(TAG, "upload start");
try {
String requestUrl = "http://192.168.1.101:8083/upload/upload/execute.do";
//請求普通信息
Map params = new HashMap();
params.put("username", "張三");
params.put("pwd", "zhangsan");
params.put("age", "21");
params.put("fileName", imageFile.getName());
//上傳文件
FormFile formfile = new FormFile(imageFile.getName(), imageFile, "image", "application/octet-stream");
SocketHttpRequester.post(requestUrl, params, formfile);
Log.i(TAG, "upload success");
} catch (Exception e) {
Log.i(TAG, "upload error");
e.printStackTrace();
}
Log.i(TAG, "upload end");
}
}
5)、修改清單文件
<?xml version="1.0" encoding="utf-8"?>
