d3.js从以下网址获得JSON [英] d3.js get JSON from url

问题描述

的情况是，我试图让D3读取存储在Windows Azure的Blob存储一个JSON文件。如果我的网址粘贴到浏览器然后将文件下载到我的机器。我希望能够得到与D3的URL JSON文件，但没有图形产生这使我相信，D3是无法读取该文件。

The situation is that i am trying to get d3 to read a JSON file which is stored in Windows Azure Blob storage. If i paste the url into a browser then the file is downloaded to my machine. I would like to be able get the JSON file from the url with d3, but no graph is produced which leads me to believe that the d3 is unable to read the file.

下面是code的一个片段：

Here is a snippet of the code:

            var url = "http://storageName.blob.core.windows.net/containerName/file.json";

            d3.json("url", function (json) {

             //code here
            })

我已经设置了容器在Azure上公开的，所以我认为它应该是与URL的任何人访问。有什么建议？

I have set the container to public on Azure, so i believe that it should be accessible to anyone with the url. Any suggestions?

推荐答案

你必须设置Content-Type HTTP头对你的blob应用/ JSON。

you'll have to set the Content-Type http header to "application/json" on your blob.

可以编程方式或使用REST API，或者使用免费的实用工具一样莓探险的蔚蓝Blob存储。

It can be done programmatically or using the rest API, or using a free utility like cloudberry explorer for azure blob storage.
