关于vue 里发请求报错的问题

Question

jquery-3.3.1.js:9600 POST https://localhost:8020/ net::ERR_CONNECTION_REFUSED
koalii_new.js:103 [ERR] NetworkError,Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'https://localhost:8020/'.
/dist/#/user/contractList:1 Failed to launch 'zheshang://' because the scheme does not have a registered handler.
index.vue:186 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'split')
at index.vue:186

报错信息是这些 想问一下是不是跨域问题或者后端的问题 刚刚还好好的

Answer 1

index .vue 186行看看
无法读取未定义的属性（读取“split”）。

split是字符串方法所以 你调用这个时的对象不是字符串你打印一下看看

JavaScript split() 方法 https://www.w3school.com.cn/js/jsref_split.asp
