问题
I have this rewrite rule:
<rule name="rentals by proptype+state+city+street test" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{UNENCODED_URL}" pattern="^/([a-zA-Z0-9\-+]+)/rent/province/([a-zA-Z\-+]+)/street/([a-zA-Z0-9%\-+]+)/([0-9a-zA-Z%\-+']+)$" />
</conditions>
<action type="Rewrite" url="search_new.aspx?proptype={C:1}&province={C:2}&city={C:3}&street={C:4}" appendQueryString="true" />
</rule>
I also tried:
<rule name="rentals by proptype+state+city+street test" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{UNENCODED_URL}" pattern="^/([a-zA-Z0-9\-+]+)/rent/province/([a-zA-Z\-+]+)/street/([a-zA-Z0-9%\-+]+)/([0-9a-zA-Z%\-+']+)$" />
<add input="{QUERY_STRING}" pattern=".*" />
</conditions>
<action type="Rewrite" url="search_new.aspx?proptype={C:1}&province={C:2}&city={C:3}&street={C:4}" appendQueryString="true" />
</rule>
This URL works: http://www.example.com/apartment/rent/province/texas/street/houston/mystreet
But when I add query string parameters, the URL throws a 404: http://www.example.com/apartment/rent/province/texas/street/houston/mystreet?rooms=3&pricemin=2500
I already checked here:
IIS URL Rewrite not working with query string
https://docs.microsoft.com/en-us/iis/extensions/url-rewrite-module/url-rewrite-module-configuration-reference
https://msdn.microsoft.com/en-us/library/ms972974.aspx
It seems I have to use a QUERY_STRING
server variable.
I actually just want to append the query string parameters, without having to write a special mapping for each parameter. I thought I could solve this through the appendQueryString="true"
property, but that apparently doesn't work.
How can I make sure my rewrite rule works also with query string parameters?
回答1:
When I look at your rule, I understand that you are looking for a complete match (^...$
) with URL Path.
However {UNENCODED_URL}
may contain query strings too. So this breaks your rule when the URL contains any query string, even if it's just a query separator (?
).
To fix this you should look for a match until the beginning of the query string instead, not till the end.
Try the following rule.
<rule name="rentals by proptype+state+city+street test" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{UNENCODED_URL}" pattern="^/([a-zA-Z0-9\-+]+)/rent/province/([a-zA-Z\-+]+)/street/([a-zA-Z0-9%\-+]+)/([0-9a-zA-Z%\-+']+)" />
</conditions>
<action type="Rewrite" url="search_new.aspx?proptype={C:1}&province={C:2}&city={C:3}&street={C:4}" appendQueryString="true" />
</rule>
