一,前后端分离跨域解决,nginx反向代理。
1,安装配置
现在我们已经把前端页面和后端接口都给写好了,但是取请求的时候就会跨域,报错。
怎么解决呢?可以使用nginx反向代理。
我们先下载一下nginx。
nginx下载地址,http://nginx.org/en/download.html。
下载安装就行了。
打开安装的目录,进入conf文件,我们要对其进行修改配置,适应我们的项目。
//找到location 注释掉,然后再下面加这三个配置端口。 # location / { # root html; # index index.html index.htm; # } location / { proxy_pass http://localhost:8080; } location /qadmin-1.2/ { proxy_pass http://localhost:8888; } location /api/ { proxy_pass http://localhost:3000; proxy_set_header Host $host; }

修改完成后保存,进入cmd,进入nginx文件夹,开启服务。
cd C:\nginx-1.16.1 start nginx

什么是nginx呢?
简单的说就是一个web服务器,它能够统一你本机的所有服务,做成一个方向的路口,并且根据请求的路径给它选择正确的响应服务。
1,如果我们的请求的是后台接口,那它就会把请求分配给node后台。
2,如果我们请求的是前端页面,那它就会把请求分配给前端界面。
二,编写前端api 1,user.js
