代号一中的分段图像上传问题

Question

我正在使用此代码上传图像。它适用于模拟器，但在Android设备(OS 6.0(上总是失败

我的代码是

`private void uploadImage3(final String imagePath, String id){
        final Hashtable htArg = new Hashtable();
        htArg.put("pk1value", id);
        htArg.put("pk2value", "");
        htArg.put("pk3value", "");
        htArg.put("datatype", "6");
        htArg.put("module", "");
        htArg.put("action", "");
        try {
            htArg.put("thefile", FileSystemStorage.getInstance().openInputStream(imagePath));
        } catch (IOException ex) {
            Log.p("imgRequest.Error = " + ex.toString());
        }
        htArg.put("submit", "Submit");

        final String boundary = "-----------------------------0123456789012";

真实设备上跟踪的错误是，

不确定我错过了什么。

请有人可以帮助我。

谢谢

更新的代码

`private void uploadImage4(final String imagePath, String id){
        MultipartRequest request = new MultipartRequest(){

如果您在多部分请求中覆盖buildRequestBody，则会有效地禁用其功能...

所有这些代码都是不正确的，不应该存在。默认情况下，多部分适用于大文件。
