很多時候我們都會遇到跨域問題，現在最普遍的解決問題的辦法就是nginx，不會安裝的請看我上一篇博客，nginx的簡單使用，本篇主要介紹本地的html文件如何訪問后端電腦的接口文件，或者訪問線上的接口地址文件
nginx配置
本地配置
location / {
root E:/nginxtext/index; //本地的項目地址
index index.html index.htm; //項目初始文件
}
轉發配置
location /api/ {
proxy_pass http://47.104.17.68:9091/hrsys/; //轉發到線上接口
proxy_set_header: Host $host;
}
注意：配置文件內不能出現注釋，否則會報錯。

<!-- 引入jq -->

<script>
getNginx()
function getNginx() {
let data = {
"passWord": "123456",
"userAccount": "123456"
}
$.ajax({
url: "/api/login", //請求的url地址 相當於http://47.104.17.68:9091/hrsys/queryUser
dataType: "json", //返回格式為json
async: true, //請求是否異步，默認為異步，這也是ajax重要特性
contentType: "application/json", //傳遞的格式為json格式
data:JSON.stringify(data), //參數值
type: "POST", //請求方式
beforeSend: function () {
//請求前的處理
},
success: function (req) {
//請求成功時處理
console.log(req)
},
complete: function () {
//請求完成的處理
},
error: function () {
//請求出錯處理
}
});
}
