nginx: How to keep double slashes in urls

问题:

I have web service which takes several filter parameters, something like :

http://mydomain.com/filter1/value1/filter2/value2/filter3/value3

The tricky thing is sometimes some of the filter variables are absent, so urls as such could be passed to this service:

http://mydomain.com/filter1//filter2//filter3/value3

Now I need to configure my nginx (or fastcgi) to keep the double slashes. Currently it's replacing double slashes to single ones. I'm new to nginx & fastcgi configuration and I don't know how to do that. I captured the request_uri from my php script when I requested the second url, and I got

http://mydomain.com/filter1/filter2/filter3/value3

Plz help me. Thanks in advance.

回答1:

syntax: merge_slashes [on|off]
default: merge_slashes on
context: http, server

You must use: merge_slashes off;

I had a similar issue with nginx+passenger (for Ruby on Rails / Rack / etc.), and I confirm that by default, multiple slashes are collapsed (in both PATH_INFO and REQUEST_URI).

Adding merge_slashes off; in the server context of the nginx configuration fixed it (I now see multiple slashes alright).

Also, make sure you don't have a trailing slash in the proxy_pass line!

• GOOD: proxy_pass http://localhost:3000;

• BAD: proxy_pass http://localhost:3000/;

As per previous answers, the solution is to use merge_slashes off; in your Nginx config. However, if you use virtual hosts, then it looks like you need to include it in your first host. That is the case on v1.4.1 and v1.4.6.
