if (window.__wxjs_is_wkwebview) {

if (window.entryUrl === '' || window.entryUrl === undefined) {

var url = `${location.origin}${to.fullPath}`

window.entryUrl = url

}

})

async setJsSign(fn) {

const baseUrl = process.env.VUE_APP_BASE_URL === '/' ? '' : process.env.VUE_APP_BASE_URL

let url = window.location.origin + baseUrl + this.$route.fullPath
