使用方法：
//1、在页面引用
import {http} from '../../common/js/request.js'
//2、发起请求
//要传给后台的参数
let params = {
    admin_id: this.adminId,
    clean_log_id: this.cleanlogId
}
http('POST','请求的url',params).then(res => {
    if(res){
        uni.showToast({
            title: res.value,
            icon: 'none',
            duration: 1500
        })
    }
    this.showSure = false;
})
