Solution to the failure of uniapp to send a post request Method:

Regarding the cross-domain issue in uni-app, some people use browser plug-ins to lift the chrome browser CORS restrictions, some people modify manifest.json to achieve cross-domain purposes, and some people use it Intermediate plug-ins are used to complete it. But no matter which method is used, I hope everyone will always remember that everything remains the same. All operations are a collection of basic requests and data operations. Therefore, this note uses uni-app and jquery. Mixed use.

1. First introduce jQuery into the Vue file.

import jQuery from "@../../common/js/jquery-3.4.1.min.js";

2. jQuery initiates an Ajax request.

//请求接口数据
                var postData = {"account":mobile,"password":passwd};
                jQuery.ajax({
                    url:this.apiUrl+'index/login',
                    type:"post",
                    dataType:"json",
                    data:postData,
                    success:function(data){
                        if(data.code == 0){
                            uni.hideLoading();
                            uni.showToast({
                                title:"登陆成功",
                                icon:"none"
                            })
                            //将用户数据写入本地并执行跳转
                            uni.setStorage({
                                key:'user_info',
                                data:data.data,
                            })
                            uni.navigateTo({
                                url:'../index/index'
                            })
                        }else{
                            uni.showToast({
                                title:data.msg,
                                icon:none
                            })
                        }
                    },
                    error:function(){
                        uni.showToast({
                            title:"请求异常",
                            icon:none
                        })
                    }
