如何使用 servlet 将我的 Phonegap 应用程序的图片上传到服务器?
我的功能如下所示:
function uploadPhoto(imageURI) {
var options = new FileUploadOptions();
options.fileKey="file";
options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
options.mimeType="image/jpeg";
var params = new Object();
params.value1 = "test";
params.value2 = "param";
options.params = params;
options.chunkedMode = true;
var ft = new FileTransfer();
ft.upload(imageURI, "http://131.246.37.167**/upload**", win, fail, options);
我的servlet是这样的:
公共类 FileUploadHandler 扩展 HttpServlet { private final String UPLOAD_DIRECTORY = "C:/uploads";
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//process only if its multipart content
if(ServletFileUpload.isMultipartContent(request)){
try {
List<FileItem> multiparts = new ServletFileUpload(
new DiskFileItemFactory()).parseRequest(request);
for(FileItem item : multiparts){
if(!item.isFormField()){
String name = new File(item.getName()).getName();
item.write( new File(UPLOAD_DIRECTORY + File.separator + name));
}
}
//File uploaded successfully
request.setAttribute("message", "File Uploaded Successfully");
} catch (Exception ex) {
request.setAttribute("message", "File Upload Failed due to " + ex);
}
}else{
request.setAttribute("message",
"Sorry this Servlet only handles file upload request");
}
request.getRequestDispatcher("/result.jsp").forward(request, response);
}
}
Der web.xml(Tomcat 日食)。
....
<servlet>
<servlet-name>FileUploadHandler</servlet-name>
<servlet-class>FileUploadHandler</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>FileUploadHandler</servlet-name>
<url-pattern>**/upload**</url-pattern>
</servlet-mapping>
....
请问有人有想法吗?
