循环将API请求与Node.js中的Axios链接-不能按顺序工作

如何解决循环将API请求与Node.js中的Axios链接-不能按顺序工作

编辑： 尝试了以下建议以及更多内容，现在这是代码，我几乎已经使所有内容异步等待，而不是然后捕获...

makeNextAccount();
  

  console.log("Making :" + merchantsToCreate.length + " Accounts")

async function makeNextAccount(currentIndex) {
    for (const item of merchantsToCreate) {

try{
    let accId = "";
    
    var createAccBody = JSON.stringify(
        {
        "email":emails[item],"firstName":"sdd","lastName":"dgdg"
    });
    
    
    var createAcc = {
      method: 'post',url: url1,headers: awsHeaders,data : createAccBody
    };

    const createdAccResult = await axios(createAcc); // wait for the request to finish

    await Promise.all(createdAccResult);
    console.log('Done!');

    accId = createdAccResult.data.accountId;
    console.log(JSON.stringify("ACCOUNT CREATED:" + accId));
} catch(err) {
    console.log("ERROR Create acc:" + err );
  }

  try{
    var initUnAuthBody = JSON.stringify(
        {
            "accountId": accId
        });
    
    var initUnAuth = {
      method: 'post',url: url2,data : initUnAuthBody
    };
    
    const initUnAuthResult = await axios(initUnAuth); // wait for the request to finish
    console.log(JSON.stringify("Init unAuth for:" +accId+",with response:" + initUnAuthResult.status));

  }catch(err) {
    console.log("ERROR unautinit:" + err);
  }

  try{
    var provisionBody = JSON.stringify(
        {
            "name":  accId,"active": "1"

        });
    
    var provision = {
      method: 'post',url: url3,data : provisionBody
    };

    const provisionResult = await axios(provision); // wait for the request to finish
    console.log(JSON.stringify("Provision for:" + accId+",with response:" +  provisionResult.status));

}catch(err) {
    console.log("ERROR provision:" + err);
  }

  try{
    var salesForceRecordody = JSON.stringify(
        {
            "email": emails[item],"accountId":  accId,});
    
    var salesForceRecord = {
      method: 'post',url: url4,data : salesForceRecordody
    };

    const salesForceRecordResult = await axios(salesForceRecord); // wait for the request to finish

    console.log(JSON.stringify("SalesForce Record for:" +accId+",with response:" + salesForceRecordResult.status));

    accCreatedList.push(accId); // Push to created list only when all steps are done
}catch(err) {
    console.log("ERROR Salesforce:" + err);
  }

    }
 }

其结果是，如您所见，返回400错误，但我不知道如何在axios中使用异步等待时如何从服务器获得完整响应，它在使用then和抓住，但我只能得到这个简单的答复。

在控制台中打印正文/标题时，一切似乎都很好，这与我之前所做的请求相同，但是由于某种原因在这里失败...

解决方法

使用async / await相对简单：

for(...) {
   const result = await axios(...); // wait for the request to finish
   // do something with your result
}

,

基本上，您需要让函数返回axios正在创建的Promise。很难说出样本的间距，但是看起来像在该行中添加return即可：

return axios(createAcc)

然后，您无需进行setTimeout并循环，而是需要进行第一个调用，等待其结束，然后在then()方法中，如果有一个调用，则进行下一个调用：

var merchantsToCreate = getFromSomewhere();
var currentIndex = 0;

function makeNextAccount() {
  if (currentIndex < merchantsToCreate.length - 1) {
    currentIndex++;
    accountCreationFlow(merchantsToCreate[i],emails[i])
      .then(makeNextAccount); // <- will make the next account
  }
}

makeNextAccount(); // kick off the "loop"

,

我唯一可以用来解决此问题的解决方案是：

1. 使用位于异步函数中的For..in循环
2. 使用这种请求方式：const ProvisionResult =等待axios（provision）
