在 GAE Go 中上传文件 [英] Upload file in GAE Go

问题描述

我正在尝试在我的 GAE 应用中上传文件.如何使用 Go 和使用 r.FormValue() 在 Google App Engine 中上传文件?

I am trying to upload a file in my GAE app. How do I the upload of a file in Google App Engine using Go and using the r.FormValue()?

推荐答案

我设法通过使用中间返回参数其他"来解决我的问题.下面的这些代码在上传处理程序中

I managed to solve my problem by using the middle return param, "other". These code below are inside the upload handler

blobs, other, err := blobstore.ParseUpload(r)

然后分配对应的formkey

Then assign corresponding formkey

file := blobs["file"]
**name := other["name"]** //name is a form field
**description := other["description"]** //descriptionis a form field

并在我的结构值赋值中像这样使用它

And use it like this in my struct value assignment

newData := data{
  Name: **string(name[0])**,
  Description: **string(description[0])**,
  Image: string(file[0].BlobKey),          
}

datastore.Put(c, datastore.NewIncompleteKey(c, "data", nil), &newData )

不是 100% 确定这是正确的，但这解决了我的问题，它现在正在将图像上传到 blobstore 并将其他数据和 blobkey 保存到数据存储区.

Not 100% sure this is the right thing but this solves my problem and it is now uploading the image to blobstore and saving other data and blobkey to datastore.

希望这也可以帮助其他人.
