使用httpClient進行上傳至遠程服務器，具體代碼如下：
1、客戶端代碼，需要髮指定參數傳至服務器
/**
*
* 需要傳遞四個參數：url,remoteFilePath,fileName,localFilePathName;
* url:http://192.168.0.125:8080/gagb/remoteFileUpload
* remoteFilePathName:\upload\intelligence\201701\03\006301\77c39cc1-1b7e-4d57-b745- a475cbdad256
* localFilePathName: D:\Apache\apache-tomcat- 6.0.45\webapps\upload\intelligence\201701\03\006301\77c39cc1-1b7e-4d57-b745-a475cbdad256
*/
public static String submitPost(String url,String remoteFilePathName, String localFilePathName){
HttpClient httpclient = new DefaultHttpClient();
try {
HttpPost httppost = new HttpPost(url);
FileBody bin = new FileBody(new File(localFilePathName));
//FileBody bin2 = new FileBody(new File(filepath + File.separator + filename2));
StringBody comment1 = new StringBody(remoteFilePathName);
//StringBody comment = new StringBody(fileName);
MultipartEntity reqEntity = new MultipartEntity();
// 先傳遞屬性，在傳遞文件
reqEntity.addPart("remoteFilePath", comment1);//filename1爲請求後臺的普通參數;屬性
//reqEntity.addPart("fileName", comment);//filename1爲請求後臺的普通參數;屬性
reqEntity.addPart("file1", bin);//file1爲請求後臺的File upload;屬性
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
int statusCode = response.getStatusLine().getStatusCode();
if(statusCode == HttpStatus.SC_OK){
System.out.println("服務器正常響應.....");
HttpEntity resEntity = response.getEntity();
System.out.println(EntityUtils.toString(resEntity));//httpclient自帶的工具類讀取返回數據
System.out.println(resEntity.getContent());
EntityUtils.consume(resEntity);
return "success";
} else {
return "fail";
}
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return "fail";
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return "fail";
} catch (Exception e) {
e.printStackTrace();
return "fail";
}finally {
try {
httpclient.getConnectionManager().shutdown();
} catch (Exception ignore) {
ignore.printStackTrace();
return "fail";
}
}
}
2、服務器端代碼，該服務器端的代碼寫在一個servlet中；
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
System.out.println("============進入遠程上傳方法servlet==================");
PrintWriter out = null;
response.setContentType("text/html;charset=UTF-8");
// 獲取遠程服務器的上下文路徑
String contextPath = request.getSession().getServletContext().getRealPath(String.valueOf(File.separatorChar));
File realPath1File = new File(contextPath);
String webappsPathString = realPath1File.getParent();
Map map = new HashMap();
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
File directory = null;
List<FileItem> items = new ArrayList<FileItem>();
try {
items = upload.parseRequest(request);
// 得到所有的文件
Iterator<FileItem> it = items.iterator();
while (it.hasNext()) {
FileItem fItem = (FileItem) it.next();
String fName = "";
Object fValue = null;
String fPath = null;
if (fItem.isFormField()) { // 普通文本框的值
fName = fItem.getFieldName();
// fValue = fItem.getString();
fValue = fItem.getString("UTF-8");
map.put(fName, fValue);
} else { // 獲取上傳文件的值
fName = fItem.getFieldName();
fValue = fItem.getInputStream();
map.put(fName, fValue);
String name = fItem.getName();
if(name != null && !("".equals(name))) {
name = name.substring(name.lastIndexOf(File.separator) + 1);
// //String stamp = StringUtils.getFormattedCurrDateNumberString();
//String timestamp_Str = TimeUtils.getCurrYearYYYY();
//String timestamp_Str = UUID.randomUUID().toString();
String remoreFilePath = (String)map.get("remoteFilePath");
String direcPath = remoreFilePath.substring(0, remoreFilePath.indexOf(name));
directory = new File(webappsPathString+direcPath);
if (!directory.exists()) {
directory.mkdirs();
}
//String filePath = ("e://test")+ timestamp_Str+ File.separator + name;
String filePath = ("e://test")+File.separator + name;
String allPath = webappsPathString+remoreFilePath;
map.put(fName + "FilePath", allPath);
InputStream is = fItem.getInputStream();
FileOutputStream fos = new FileOutputStream(allPath);
byte[] buffer = new byte[1024];
while (is.read(buffer) > 0) {
fos.write(buffer, 0, buffer.length);
}
fos.flush();
fos.close();
map.put(fName + "FileName", name);
}
}
}
} catch (Exception e) {
System.out.println("讀取http請求屬性值出錯!");
// e.printStackTrace();
}
// 數據處理
try {
out = response.getWriter();
out.print("{success:true, msg:'接收成功'}");
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
