小编Pav*_*aju的帖子

我也搜索了谷歌,stackoverflow和其他来源.但到目前为止没有运气.

我正在开发一个GAE应用程序,后端是Java,另一端是android.现在服务器是在本地机器上设置的,它是由android通过wifi使用ip地址访问的.

在尝试上传图片时,我首先请求uploadUrl,我成功了.唯一的问题我看到有而不是PC的IP地址,它有个人电脑名称.所以现在我将pc名称替换为ip地址.

在我实际尝试发布多部分图像文件之后,它会抛出异常 java.lang.IllegalStateException: Must call one of set*BlobStorage() first

现在我无法通过这个障碍.我看到了可能的原因

1. 我正在将pc名称更改为ip地址 - 使链接无效altogather
2. 正如在某处读到的那样,这个网址只能被击中一次,但我只打了一次.
3. 开发环境是问题,只剩下解决方案就是部署它？

请帮帮我.对此严重困扰.非常感谢提前
