d3.js - D3 doesn't load a CSV file from an external URL

Question

I'm trying to load a CSV file using D3.csv(MY_EXTERNAL_URL) function,but it doesn't load. Seems that it doesn't find the file itself.

Here is my code.

d3.csv ("http://localhost:8080/SOME_LINK", function (tuples) {
console.log(tuples);
//tuples is empty
});

However, when I copy/paste MY_EXTERNAL_URL on browser it downloads the CSV file instantly.

Any help would be much appreciated.

I'm thinking maybe I miss some headers?

Thanks in advance.

“外部”是指来自另一个域/网站？

我猜你遇到了浏览器的同源策略。您不能向另一个域发出 ajax 请求，这是您的浏览器禁止的。

您确定您使用的是 d3.csv 函数吗？因为您的代码说您正在使用 d3.json 函数。如果这不起作用，您可能需要将“.csv”结尾添加到文件中，然后将其打开为 SOME_LINK.csv
