微信小程序获取当前页面路径及参数的代码如下：
const pages = getCurrentPages()
const currentPage = pages[pages.length - 1]
const url = currentPage.route
const options = currentPage.options
let urlargs = `/${url}?`
for (let key in options) {
const value = options[key]
urlargs += `${key}=${value}&`
}
urlargs = urlargs .substring(0, urlargs .length - 1)
console.log(urlargs) // /pages/index/task/task?identityTask=2&taskId=e92d6acf95f54ea494a73e443df7c45e
