在文档中:

http://cran.r-project.org/web/packages/httr/httr.pdf,它只说:

Further parameters, such as query, path, etc, passed on to modify_url. These parameters must be named.

然后在 modify_url 部分中,它说:

components of the url to change

还有一个例子:

# You might want to manually specify the handle so you can have multiple
# independent logins to the same website.
google <- handle("http://google.com")
GET(handle = google, path = "/")
GET(handle = google, path = "search")

path = "/"但是(就像 R 文档中的许多示例一样,LOL!),该示例并没有说明使用vs之间的区别path = "search"

那么,是path为了什么?
