配置當前路徑映射到(arrive)其他(he)端口路徑上，解決跨域問題

gulp.task('server', function() {
    gulp.src(dist)
        .pipe(webserver({
            host: 'localhost',
            port: 80,
            path: '/',
            livereload: false,
            proxies: [{
                source: '/h5',
                target: 'http://localhost:8080/h5'
            }]
        }))
});
