使用gulp解决前端本地跨域请求代理

gulpfile.js

var gulp = require('gulp');
var concat = require('gulp-concat');
var uglify = require('gulp-uglify');
var autoprefixer = require('gulp-autoprefixer');
var useref = require('gulp-useref');
var connect = require('gulp-connect');
var proxyMiddleware = require('http-proxy-middleware');


// 跨域代理  将localhost:8088/api 映射到 https://api.shujumohe.com/  代理src目录
gulp.task('server', ['listen'], function() {
    var middleware = proxyMiddleware(['/api'], {
        target: 'https://api.shujumohe.com/',
        changeOrigin: true,
        pathRewrite: {
            '^/api': '/'
        }
    });
    connect.server({
        root: './src' ,
        port: 8088,
        livereload: true,
        middleware: function(connect, opt) {
            return [middleware]
        }

// 代理dist目录

        .pipe(autoprefixer({

        .pipe(gulp.dest('dist/vendors/css'));



    return gulp

gulp.task('js', function() {

            .pipe(connect.reload());
    });
