前言

本专栏为【H5】，主要介绍前端知识点。

一、技术介绍

跨越介绍

二、问题描述

vue2与netcore webapi跨越问题解决

三、问题解决

3.1 方法一：前端Vue修改

配置代理转发，加URL拦截，转换成新的URL
vue.config.js文件，加一下代码：

    proxy:{'/api': { // api表示拦截以/api开头的请求路径target: 'http://localhost:5296/api', //跨域的域名changeOrigin:true,//是否开启跨域pathRewrite:{ '^/api':'' // 重写请求，把/api变为空字符}}}

3.2 方法二：后端允许Cors跨越访问

Program.cs文件

//配置跨域
builder.Services.AddCors(c =>
{c.AddDefaultPolicy(policy =>{policy.AllowAnyOrigin()//允许所有来源的访问.AllowAnyHeader()//允许所有类型的请求头.AllowAnyMethod();//允许所有类型的请求});
});

启动跨越，在run之前

app.UseCors();
app.UseHttpsRedirection();

vue.config.js文件

'use strict'
const path = require('path')
const defaultSettings = require('./src/settings.js')function resolve(dir) {return path.join(__dirname, dir)
}const name = defaultSettings.title || 'vue Admin Template' // page title// If your port is set to 80,
// use administrator privileges to execute the command line.
// For example, Mac: sudo npm run
// You can change the port by the following methods:
// port = 9528 npm run dev OR npm run dev --port = 9528
const port = process.env.port || process.env.npm_config_port || 9528 // dev port// All configuration item explanations can be find in https://cli.vuejs.org/config/
