android中如何上傳圖片到FTP服務(wù)器
android客戶(hù)端實(shí)現(xiàn)FTP文件需要用到 commons-net-3.0.1.jar
創(chuàng)新互聯(lián)是一家專(zhuān)業(yè)提供八宿企業(yè)網(wǎng)站建設(shè),專(zhuān)注與網(wǎng)站建設(shè)、做網(wǎng)站、HTML5、小程序制作等業(yè)務(wù)。10年已為八宿眾多企業(yè)、政府機(jī)構(gòu)等服務(wù)。創(chuàng)新互聯(lián)專(zhuān)業(yè)網(wǎng)站制作公司優(yōu)惠進(jìn)行中。
先將jar包復(fù)制到android libs目錄下
復(fù)制以下實(shí)現(xiàn)代碼
以下為實(shí)現(xiàn)代碼:
/**

* @param password 密碼
* @param remotePath 上到ftp服務(wù)器的磁盤(pán)路徑
* @param fileNamePath 要上傳的文件路徑
* @param fileName 要上傳的文件名
* @return
*/
public String ftpUpload(String url, String port, String username,String password, String remotePath, String fileNamePath,String fileName) {
FTPClient ftpClient = new FTPClient();
FileInputStream fis = null;
String returnMessage = "0";
try {
ftpClient.connect(url, Integer.parseInt(port));
boolean loginResult = ftpClient.login(username, password);
int returnCode = ftpClient.getReplyCode();
if (loginResult FTPReply.isPositiveCompletion(returnCode)) {// 如果登錄成功
ftpClient.makeDirectory(remotePath);
// 設(shè)置上傳目錄
ftpClient.changeWorkingDirectory(remotePath);
ftpClient.setBufferSize(1024);
ftpClient.setControlEncoding("UTF-8");
ftpClient.enterLocalPassiveMode();
fis = new FileInputStream(fileNamePath + fileName);
ftpClient.storeFile(fileName, fis);
returnMessage = "1"; //上傳成功
} else {// 如果登錄失敗
returnMessage = "0";
}
} catch (IOException e) {
e.printStackTrace();
throw new RuntimeException("FTP客戶(hù)端出錯(cuò)！", e);
} finally {
//IOUtils.closeQuietly(fis);

android如何實(shí)現(xiàn)圖片批量上傳？？
首先，以下架構(gòu)下的批量文件上傳可能會(huì)失敗或者不會(huì)成功：
1.android客戶(hù)端+springMVC服務(wù)端：服務(wù)端采用org.springframework.web.multipart.MultipartHttpServletRequest作為批量上傳接收類(lèi)，這種搭配下的批量文件上傳會(huì)失敗，最終服務(wù)端只會(huì)接受到一個(gè)文件，即只會(huì)接受到第一個(gè)文件?？赡芤?yàn)镸ultipartHttpServletRequest對(duì)servlet原本的HttpServletRequest類(lèi)進(jìn)行封裝，導(dǎo)致批量上傳有問(wèn)題。
2.android客戶(hù)端+strutsMVC服務(wù)端：
上傳成功的方案：
采用android客戶(hù)端+Servlet（HttpServletRequest）進(jìn)行文件上傳。
Servlet端代碼如下：
[java] view plaincopyprint?
DiskFileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
try
{
List items = upload.parseRequest(request);
Iterator itr = items.iterator();
while (itr.hasNext())
{
FileItem item = (FileItem) itr.next();
if (item.isFormField())
{
System.out.println("表單參數(shù)名:" + item.getFieldName() + "，表單參數(shù)值:" + item.getString("UTF-8"));
}
else
{
if (item.getName() != null !item.getName().equals(""))
{
System.out.println("上傳文件的大小:" + item.getSize());
System.out.println("上傳文件的類(lèi)型:" + item.getContentType());
// item.getName()返回上傳文件在客戶(hù)端的完整路徑名稱(chēng)
System.out.println("上傳文件的名稱(chēng):" + item.getName());
File tempFile = new File(item.getName());
// 上傳文件的保存路徑
File file = new File(sc.getRealPath("/") + savePath, tempFile.getName());
item.write(file);
request.setAttribute("upload.message", "上傳文件成功！");
} else
{
request.setAttribute("upload.message", "沒(méi)有選擇上傳文件！");
}
}
}
}
catch (FileUploadException e)
{
e.printStackTrace();
}
catch (Exception e)
{
e.printStackTrace();
request.setAttribute("upload.message", "上傳文件失?。?);
}
request.getRequestDispatcher("/uploadResult.jsp").forward(request, response);
android端代碼如下：
[java] view plaincopyprint?
public class SocketHttpRequester {
/**

android 客戶(hù)端開(kāi)發(fā) 如何同時(shí)上傳多張照片
1、在微博頁(yè)面點(diǎn)擊左上角發(fā)布按鈕后，點(diǎn)擊“照相機(jī)”標(biāo)識(shí)或“圖片”標(biāo)識(shí);
2、選擇圖片進(jìn)行上傳，選定后點(diǎn)擊右下角的綠色“確認(rèn)”按鈕
3、多圖上傳最多支持9張圖片，如果還需添加可點(diǎn)擊“十”字繼續(xù)選擇上傳，如果添加完畢可點(diǎn)擊右上角的藍(lán)色“發(fā)布”即可。
