vue 针对多端口的情况下文件上传处理方法
在一个项目中,可能会存在多个端口号,因为不同的业务作为区分,需要多个端口号:
解决方案,
·1.在特定的端口号中api 接口中进行加入特定的字符
2.针对api的形式,使用formData来进行上传
3.增加针对formdata的数据进行上传方式
实例:
1.在request.js中添加针对文件上传的方式
if(config.url.indexOf("?extra_myself=test")!=-1){
let url = config.baseURL;
url = url.replace('48080/admin-api','48081/bus-api');
config.baseURL = url;
}
console.log(config)
里面的48080/admin-api 和48081/bus-api 就是不同的端口号和接口信息
