1、在config.js中配置不同的base路径 

2、在request.js中设置axios不同的实例

// 创建axios实例
const service1 = axios.create({
  baseURL: window.g.SERVICE_CONTEXT_PATH,
});
const service2 = axios.create({
  baseURL: window.g.SERVICE_CONTEXT_PATH2,
});

3、在封装的方法中通过不同的实例去调取

export function post(url,data){
  return new Promise((resolve,reject) => {
    service1.post(url,data)
        .then(response => {
          resolve(response.data);
        },err => {
          reject(err)
        })
  })
}

export function post2(url,data){
  return new Promise((resolve,reject) => {
    service2.post(url,data)
        .then(response => {
          resolve(response.data);
        },err => {
          reject(err)
        })
  })
}

搞定
