I'm to work with goo.gl for URL shortening. I need to make the following request:

POST https://www.googleapis.com/urlshortener/v1/url
Content-Type: application/json

    <button type="submit"> submit </button>
</form>

我如何在这里添加'content-type'和json？

how do i add the 'content-type' and json here?

推荐答案

浏览器不支持JSON作为表单提交的媒体类型（支持的类型是在规范中列出。

Browsers do not support JSON as a media type for form submissions (the supported types are listed in the spec).

从网页发出此类请求的唯一方法是使用XMLHttpRequest对象。

The only way to make such a request from a web page is to use the XMLHttpRequest object.

Google提供一个JavaScript库（包装XMLHttpRequest），可以与网址缩短API 。

Google provide a JavaScript library (which wraps XMLHttpRequest) that can interact with their URL Shortener API.
