我无法解决这个问题.

url = "www.mysite.com/?param1=abc"

redirect_to(url,:param2 => 'xyz')

### Should this go to - www.mysite.com/?param1=abc&param2=xyz

或者我错过了什么？它似乎不起作用？

解决方法

从 documentation：

redirect_to(options = {},response_status = {})

Redirects the browser to the target specified in options. This
parameter can take one of three forms:

Hash – The URL will be generated by calling url_for with the options.

Record – The URL will be generated by calling url_for with the
options,which will reference a named URL for that record.

String starting with protocol:// (like http://) or a protocol relative
reference (like //) – Is passed straight through as the target for
redirection.

你传递一个String作为第一个参数,所以它使用第三个选项.您的第二个参数被解释为response_status参数的值.

因此,如果您的重定向是内部重定向(到同一个应用程序),则无需指定方案和主机名.只是用

redirect_to root_url(param1 => 'abc',param2 => 'xyz')

如果是外部URL,请在重定向之前构建完整的URL：

url = "www.mysite.com/?param1=abc&params2=xyz"
redirect_to url
