Question

我无法在手机版本的android版本中上传手机拍摄的图像。对于iOS，它工作正常，但相同的代码不适用于使用手机间隙的Android版本

我收到200条响应代码，但服务器没有“成功”响应。

我使用的是cordova-1.7.0.js，目标SDK是Android 2.1。

以下是示例代码：

function imageUpload(imageURI)
{
    var options = new FileUploadOptions();
    options.fileKey="image";
    options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
    options.mimeType="image/jpeg";
    var params = new Object();
    var msg="test message";
    var token= "test token";
    params.message = msg;
    params.access_token = token;
    options.params = params;
    var ft = new FileTransfer();
    ft.upload(imageURI, "http://mydomain.info/demo/upload.php", win, fail, options,false);
}

另外不要忘记将相机权限添加到Android模拟器

首先确保调用doPost方法如果没有调用write doGet（）方法，那么调用内部会以下列方式发布

protected void doGet(HttpServletRequest request, HttpServletResponse response) {
    doPost(request,response);
}

然后，您需要将以下jar文件放在WEB-INF

下的lib文件夹中

公地文件上传-1.2.2.jar
公地文件上传-1.2-javadoc.jar
公地文件上传-1.2-sources.jar
公地-IO-1.3.2.jar

还将它们放在构建路径中。

现在我们在Cordova-1.9.0上也添加了apache库：commons-io-2.4.JARS

我一直在尝试将图像从phonegap android模拟器上传到servlet来存储图像

Servlet代码：uploadpic.java

private static final String BASE_DIRECTORY = "/Users/tshah/Pictures";

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

//  boolean isMultipart = ServletFileUpload.isMultipartContent(request);

    System.out.println("Do post....");

    /**
    * The base upload directory. In this directory all uploaded files will
    * be stored. With the applet param tag 'directory' you can create a
    * subdirectory for a user. 
    * See http://www.javaatwork.com/parameters.html#directory for more 
    * information about the 'directory' param tag. For a Windows environment 
    * the BASE_DIRECTORY can be e.g. * 'c:/temp' for Linux environment '/tmp'.
    */


    boolean isMultipart = ServletFileUpload.isMultipartContent(request);

    // check if the http request is a multipart request
    // with other words check that the http request can have uploaded files
    if (isMultipart) {

      //  Create a factory for disk-based file items
      FileItemFactory factory = new DiskFileItemFactory();

      //  Create a new file upload handler
      ServletFileUpload servletFileUpload = new ServletFileUpload(factory);

      // Set upload parameters
      // See Apache Commons FileUpload for more information
      // http://jakarta.apache.org/commons/fileupload/using.html
      servletFileUpload.setSizeMax(-1);

      try {

        String directory = "";

        // Parse the request
        List items = servletFileUpload.parseRequest(request);

        // Process the uploaded items
        Iterator iter = items.iterator();

        while (iter.hasNext()) {
          FileItem item = (FileItem) iter.next();

          // the param tag directory is sent as a request parameter to
          // the server
          // check if the upload directory is available
          if (item.isFormField()) {

            String name = item.getFieldName();

            if (name.equalsIgnoreCase("directory")) {

              directory = item.getString();
            }

            // retrieve the files
          } else {

            // the fileNames are urlencoded
            String fileName = URLDecoder.decode(item.getName());

            File file = new File(directory, fileName+".jpeg");
            file = new File(BASE_DIRECTORY, file.getPath());

            // retrieve the parent file for creating the directories
            File parentFile = file.getParentFile();

            if (parentFile != null) {
              parentFile.mkdirs();
            }

            // writes the file to the filesystem
            item.write(file);
          }
        }

      } catch (Exception e) {
        e.printStackTrace();
        response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
      }

      response.setStatus(HttpServletResponse.SC_OK);

    } else {
      response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
    }
}

Answer 4

我遇到了同样的问题。我用添加代码

修复了它

System.setProperty("http.keepAlive", "false");

在onCreate（）方法开头的主java文件中。这个错误是apache cordova的unresolved bug。

Answer 5

在这里查看我的答案，这对我来说是有用的（将图像和数据发送到django rest api）以获取完整的代码：

android phonegap camera and image uploading

我想诀窍在于：

options.chunkedMode = true; //this is important to send both data and files

也许这一个：

var url=encodeURI("http://your_url_for_the_post/");

使用url编码的url传递给FileTransfer

使用PhoneGap中的FileTransfer上传问题
