什么是语法摆脱Android的一个Blob存储上传的网址是什么？ [英] What is the syntax to get a Blobstore upload url from Android?

问题描述

我Blob存储上传的GWT的工作，但现在我需要我的Andr​​oid应用程序上传到Blob存储区。我看到这个帖子里面介绍了如何上传一次，我有URL，但它并不显示获得的网址：
<一href=\"http://stackoverflow.com/questions/6177243/using-google-blobstore-with-an-android-application\">Using谷歌BLOBSTORE与Android应用程序

I have Blobstore uploads working for GWT, but now I need my Android app to upload to Blobstore. I saw this post which explains how to upload once I have the URL, but it does not show getting the URL: Using Google BlobStore with an Android application

我的问题是：

1. 请我送什么网址去？


2. 什么是获得Blob存储区？
的语法

感谢

推荐答案

我有这样的：

控件presenter.java：

Widget.presenter.java:

uploadButton.addClickHandler(new ClickHandler() {
 @Override
 public void onClick(ClickEvent event) {
 //init action
 imageService.getBlobStoreUploadUrl(new AsyncCallback<String>() {
      @Override
      public void onFailure(Throwable caught) {
        Window.alert("Oups Error at ImageUploaderPresenter");
      }
      @Override
      public void onSuccess(String result) {
        uploadForm.setActionUpload(result);
        uploadForm.submit();
      }
    }
  });
}

ImageServiceImpl.java：

ImageServiceImpl.java:

@Override
public String getBlobStoreUploadUrl() {
    //Map the UploadURL to the uploadservice which will be called by
    //submitting the FormPanel
    return blobstoreService.createUploadUrl("/imageUpload");
}
