axios.interceptors中的死循环

Question

async getSessionID() { let params = { user_type: 3 } return http('get', '/api/webConnect', params); }, axios.interceptors.request.use( async config => { let sessionID = localStorage.getItem("sessionID") if (!sessionID) { // api.getSessionID().then(async(res) => { // console.log(res) // localStorage.setItem("sessionID", res.data.sessionid) // config.params.sessionid = res.data.sessionid // }) let resp = await api.getSessionID() sessionID = resp.data.sessionid; localStorage.setItem('sessionID',sessionID) } config.params.sessionid = sessionID if (config.method === 'post') { config.data = Qs.stringify(config.data); } // store.commit("isloading", { "isloading": true }) return config; }, err => { return Promise.reject(err); } ); 发送请求之前，判断有无token，如果没有就去请求token，把token作为参数发送到后端；现在这一步死循环，网页崩溃啦

Answer 1

axios.interceptors.request.use(
    config

config前面加上async
