Axios是否有能力检测重定向? [英] Does Axios have the ability to detect redirects?

问题描述

Fetch API的响应界面具有<一个href ="https://developer.mozilla.org/zh-CN/docs/Web/API/Response/redirected" rel ="noreferrer">只读标志，redirected，它指示是否还是响应不是重定向请求的结果.

The Response interface of the Fetch API has a read-only flag, redirected, which indicates whether or not the response was the result of a request that was redirected.

axios 库是否具有类似的功能?我能找到的最好的是maxRedirects，它设置了要遵循的最大重定向数.但是，我只是想确定它是否发生(以便我可以专门处理重定向)，而不是阻止它发生.

Does the axios library have a similar capability? The best I could find is maxRedirects which sets the maximum number of redirects to follow. However, I am simply looking to determine if it happened or not (so I can handle redirects specially), not prevent it from happening.

推荐答案

如果axios公开了与获取API的 response 相同的功能.url，您可以将代码中的请求网址与响应网址；如果这些不相等，则说明请求已重定向.

If axios exposes the equivalent of the fetch API’s response.url, you can compare the request URL from your code with the response URL; if those aren’t equal, you know the request was redirected.

状态码为200，这是规范所要求的；无论您使用哪种API，都不会向浏览器中运行的前端JavaScript公开任何中间状态代码.另请参见 http://stackoverflow.com/a/46031800/441757

As far as the status code being 200, that’s what’s required by the spec; no intermediate status codes are exposed to frontend JavaScript running in a browser — regardless of which API you use. See also the answer at http://stackoverflow.com/a/46031800/441757
