You are reporting a cross-domain error. Please check if there is any problem with the interface first!

Solution 1: Backend engineers are required to cooperate in setting Access-Control-Allow-Origin to *
一定要设置 {emulateJSON: true},不然跨域不成功. 如果Web服务器无法处理编码为application/json的请求，你可以启用emulateJSON选项。启用该选项后，请求会以application/x-www-form-urlencoded作为MIME type，就像普通的HTML表单一样
Solution 2: this.$http.jsonp('...', { credentials: true }) Use JSONP
