axios关于同步执行ajax请求方法

调用函数要申明前缀async  
内部函数调用要用await

// 上传图片 OK
        async UploadFile(file, fileList) {
        
          var that = this;
          //
          var api_dateitme = await ajax.ajax_tb(
            config.api_zt + "/api/sys/datetime",
            "get",
            {
        },
            null
          );
          // ajax.ShowJsonEq(api_dateitme.data.data)
          var t_datetime = api_dateitme.data.data;
          //同步获取日期后再使用t_datetime变量
          //....
       }

// 同步
    export async function ajax_tb_test(url, type, params, p_headers) {
        
      var result = await ajax_tb(url, type, params, p_headers)
      return result.data
    }
    // 定义ajax的promise函数
    export function ajax_tb(url, type, params, p_headers) {
        
      return new Promise((resolve, reject) => {
        
        if (!p_headers) {
        
          // p_headers={ "Content-Type": "application/json" };
          p_headers = {
         'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8' }
        }
        var tUrl = url
        if (type === 'post' || type === 'POST') {
        
          axios.post(tUrl, qs.stringify(params),{
         headers: p_headers }).then(r => {
        
            resolve(r)
          }).catch(r => {
        
            gotoLoginPage(r)
          })
        }
        if (type === 'get' || type === 'GET') {
        
          axios.get(tUrl, {
        
            params: params
          }).then(r => {
        
            resolve(r)
          }).catch(r => {
        
            gotoLoginPage(r)
          })
        }
        if (type === 'put' || type === 'PUT') {
        
          axios.put(tUrl, params).then(r => {
        
            resolve(r)
          }).catch(r => {
        
            gotoLoginPage(r)
          })
        }
        if (type === 'delete' || type === 'DELETE') {
        
          axios.delete(tUrl, {
        
            params: params
          }).then(r => {
        
            resolve(r)
          }).catch(r => {
        
            gotoLoginPage(r)
          })
        }
        if (type === 'patch' || type === 'PATCH') {
        
          axios.patch(tUrl, params).then(r => {
        
            resolve(r)
          }).catch(r => {
        
            gotoLoginPage(r)
          })
        }
      })
    }
