1. Overview

As the old saying goes: take the top, get the middle; take the middle, get the bottom. So we might as well set a higher goal and work hard in order to get a better return.

two。 Using Nginx to implement redirection of URL 2.1 usage scenario

When we share a website address every day, we often have this effect. The same URL, which is opened in the browser of the computer, is an effect, while opening in the browser of the mobile phone will show another effect that is more suitable for the display of the mobile phone.

There are usually two ways to achieve this effect:

First, the use of adaptive H5 page implementation, according to the width of the window, automatically adjust the layout of the page.

Second, using Nginx, according to the terminal, jump to different pages, the computer opens, jumps to the web page used by the PC end, the mobile phone opens, and jumps to the web page used by the mobile phone.

Today we will talk about the second way, how to achieve it.

2.2 simple redirection

For some URL redirects, the new URL does not need to inherit the parameters of the original URL, such as the home page of the website. In this case, you can use return 302 in the location of the Nginx configuration file to jump.

Another situation is that the new URL needs to inherit the parameters of the original URL, in which case you need to use rewrite to rewrite the URL.

Location / {# determine whether the mobile if ($http_user_agent ~ "(MIDP) | (WAP) | (UP.Browser) | (Smartphone) | (Obigo) | (Mobile) | (AU.Browser) | (wxd.Mms) | (WxdB.Browser) | (CLDC) | (UP.Link) | (KM.Browser) | (UCWEB) | (SEMC-Browser) | (Mini) | (Symbian) | (Palm) | (Nokia) | (Panasonic) | | (MOT-) | (SonyEricsson) | (NEC-) | (Ericsson) | (BENQ) | (BenQ) | (Amoisonic) | (Amoi-) | (Capitel) | (PHILIPS) | (SAMSUNG) | (Lenovo) | (Mitsu) | (Motorola) | (WAPPER) | (LG-) | (LG/) | (EG900) | (CECT) | (Compal) | (kejian) | (Bird) | (BIRD) | (G900/V1.0) | (Arima) | (CTL) | ) | (TDG) | (Daxian) | (DAXIAN) | (Eastcom) | (EASTCOM) | (PANTECH) | (Dopod) | (Haier) | (HAIER) | (KONKA) | (KEJIAN) | (LENOVO) | (Soutec) | (SOUTEC) | (SAGEM) | (SEC-) | (SED-) | (EMOL-) | (INNO55) | (ZTE) | (iPhone) | (Android) | (Windows CE) | (Wget) | (Java) | (curl) | (Opera) ") {rewrite (\ w) -\ w +) | (\?. *) $https://www.zhuifengren.com/h6-$1-0.html$2 redirect } proxy_pass http://myUpstream;}

The syntax of rewrite is: rewrite URL redirect after regular expression rewriting

Where redirect means 302 temporary redirection, or the permanent keyword can be used to represent 301 permanent redirection.

Using rewrite to rewrite URL, you need to use the knowledge of regular expressions. After rewriting, $1 and $2 in URL represent the first string and the second string matched in the regular expression. Here you can learn about the regular expression without going into details.

The regular expression in the example (\ URL -\ w +) | (\?. *) $can change the original expression:

Https://www.zhuifengren.com/1001-1223.jsp?v=123456

Rewrite to

Https://www.zhuifengren.com/h6-1001-1223-0.html?v=123456

Add: Nginx redirects 1. 1 according to the url parameter. Judge the url path location / {if ($args ~ * "/ product-list?param1=val1¶m2=val2") {rewrite ^ http://www.mysite.com/product-list/$arg_param1/$arg_param2? Last;}} 2. Judge the url parameter if ($arg_path = 'abc') {proxy_pass http://127.0.0.1/abc/$arg_path;}

In particular, note that if is evil,nginx does not provide multi-if judgment, and there is no such judgment as or, so you can only use the following approach.

Location / api/ {if ($arg_token =') {proxy_pass http://127.0.0.1/abc} if ($http_token ='') {proxy_pass http://127.0.0.2/abc} if ($token = paraheader) {proxy_pass http://127 .0.0.3 / abc} proxy_pass http://127.0.0.1:8080/app/; Proxy_redirect off;} read here, this article "how to use Nginx to achieve URL redirection" article has been introduced, want to master the knowledge of this article still need to practice and use in order to understand, if you want to know more related articles, welcome to follow the industry information channel.
