for循环内的axios [英] Axios inside for loop

问题描述

我正在尝试在 for 循环内执行 axios 请求，但该循环甚至在 axios 之前完成.以下是我的代码:

I am trying to axios requests inside a for loop but the loop is being completed even before the axios. Following is my code:

let findEmail = async() => {
 for (var i = 0; i < csvData.length; i++){
    axios.post('https://email-finder.herokuapp.com/find', {
        "first_name": "Irinaa",
        "last_name": "xyz",
        "domain": "xyxz.com"
    }).then((response) => {
        if(response.status === 500){
            console.log('no email found');
        }
        else{
            console.log(response.data);
        }
    }, (error) => {
        console.log('no email found ', i);
    });
      console.log('axios request done');
 }
} 

我希望循环一直等到请求完成，然后再增加 i 变量.任何帮助将非常感激.谢谢

I want the loop to wait until the request is complete and then go to increment the i variable. Any help would be much appreciated. Thank you

推荐答案

当您使用异步函数时，请尝试使用 await 而不是 then.它将使您的 for 循环同步运行.

As you are in async function try using await instead of then. It will make your for loop behave synchronously.

let findEmail = async () => {
      for (var i = 0; i < csvData.length; i++) {
        try {
          let response = await axios.post(
            "https://email-finder.herokuapp.com/find",
            {
              first_name: "Irinaa",
              last_name: "xyz",
              domain: "xyxz.com"
            }
          );
          if (response.status === 500) {
            console.log("no email found");
          } else {
            console.log(response.data);
          }
        } catch (error) {
          console.log("no email found ", i);
        }
        console.log("axios request done");
      }
    };
