页面nginx配置
1,前端页面放在域名根目录,比如,http://www.xuecheng.com/ ,对应的nginx配置:
#门户location / {alias D:/Z_lhy/SpringCloud/xuecheng_online/www/xc-ui-pc-static-portal/;index index.html;}
页面目录:
接口nginx配置
2,前端请求接口路径,在域名后面加一个目录
url : "http://www.xuecheng.com/api/auth/oauth/token",//发送请求的地址
function login(){var uname = $("#username").val();var pwd = $("#password").val();$.ajax({url : "http://www.xuecheng.com/api/auth/oauth/token",//发送请求的地址 type: "post",dataType: "json",data : "username="+uname+"&password="+pwd+"&grant_type=password",beforeSend:function (request) {// 如果后台没有跨域处理,这个自定义request.setRequestHeader("Authorization","Basic RG9jV2ViQXBwOjEyMzQ1Ng==");// 禁用按钮,防止重复提交$("#submit").attr({ disabled: "disabled" });},error : function() {alert("error occured!!!");//请求失败时弹出的信息},success : function(data) {//返回的信息展示出来alert(JSON.stringify(data))}});};
nginx 对api接口配置
location /api/ {add_header 'Access-Control-Allow-Origin' $http_origin;add_header 'Access-Control-Allow-Credentials' 'true';add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';add_header 'Access-Control-Allow-Headers' 'DNT,Authorization,Accept,Origin,Keep-Alive,User-Agent,X-Mx-ReqToken,X-Data-Type,X-Auth-Token,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';if ($request_method = 'OPTIONS') {add_header 'Access-Control-Max-Age' 1728000;add_header 'Content-Type' 'text/plain; charset=utf-8';add_header 'Content-Length' 0;return 204;}proxy_pass http://apiserver/; proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_set_header X-Forwarded-Proto $scheme;proxy_connect_timeout 5;}
其中的
$http_origin
$http_origin并不是nginx的内置参数,nginx支持取自定义的参数值,$http_XXX这个格式是nginx取请求中header的XXX的值的。这里取的是origin,而一般跨域请求都会将请求的来源放在origin中(浏览器会往跨域请求的header上面加origin这个header)。
这样配置的话,前端页面在域名下:www.xuecheng.com,而访问的接口则是www.xuecheng.com/api/xxx ,这样就不存在跨域问题了,
其实nginx不配置 Access-Control-Allow-Origin也没事,因为前后端在一个域下了。
注意事项
如果你前后端访问存在跨域问题,而且你需要使用cookie,后端要想获取到前端携带过来的cookie,前后端都要做配置:
前端:
var xhr = new XMLHttpRequest() xhr.withCredentials = true xhr.open('GET', 'http://localhost:8888/', true) xhr.send(null)
后端:
Access-Control-Allow-Origin: http://www.abc.com(这里必须域名不能是*) Access-Control-Allow-Credentials: true
