问题描述
我正在尝试使用URLComponents组成一个URL，因为这似乎是它的用途.
I'm trying to use URLComponents to compose a URL as that appears to be what it's for.
但是，当我随后访问组件的url属性时，它为nil.
However, when I then access the url property of the components it is nil.
示例...
var urlComponents = URLComponents(string: "http://google.com")!
urlComponents.path = "auth/login"
那我就...
print(urlComponents)
输出...
scheme: http host: google.com path: auth/login
- scheme : "http"
- host : "google.com"
- path : "auth/login"
但是然后...
print(urlComponents.url)
输出nil.
我在这方面做错什么了吗?如何从所有这些内容中获取格式完整的URL?谢谢
Am I doing something wrong with this? How do I get the fully formed URL from all this? Thanks
推荐答案
看来path参数的字符串必须以/开头.
It looks like path parameter's string must start with /.
因此将"auth/login"更改为"/auth/login"即可.
