为什么GorillaMux不允许我传入URL作为参数？ [英] Why is GorillaMux not allowing me to pass in a URL as a parameter?

问题描述

我正在构建一个URL shortener API，我试图使用GorillaMux将一个URL传递给一个函数。路由处理器就像这样：

I'm building a URL shortener API and I'm trying to pass a URL into a function using GorillaMux. The route handler is like so:

router.HandleFunc("/new/{url}", createURL)

唯一的是，如果我传入： https://www.google.com （如localhost：8080 / new / https://www.google.com ），那么它会以 404页未找到的方式进行响应，并且该URL将更改为https：/www.google.com 。

The only thing is, if I pass in: https://www.google.com (as in localhost:8080/new/https://www.google.com) then it responds with 404 page not found and the URL is changed to https:/www.google.com.

我尝试在{url}位中添加正则表达式模式，如下所示：{url：[a-zA-Z0-9 /] +}但这似乎并没有工作，似乎有点矫枉过正，因为我检查的网址在其他地方是正确的。

I've tried adding a regexp pattern in with the {url} bit like so: {url:[a-zA-Z0-9/]+} but that didn't seem to work and seems a bit overkill since I'm checking the url is correct elsewhere.

推荐答案

以便对参数中的斜线不会混淆为url的一部分：

You need to encode it so that the slash in the parameter was not confused as a part of the url:

localhost:8080/new/https%3A%2F%2Fwww.google.com
