将 API 请求与 Node 中的 Axios 链接起来.js循环 - 无法按顺序工作

Question

已编辑：尝试了以下建议以及更多内容，现在这就是代码，我几乎只是让它全部异步等待，而不是然后和捕获。。。

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,
headers: awsHeaders,
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,
headers: awsHeaders,
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,
headers: awsHeaders,
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);
}
}
}

结果是，正如你所看到的，返回了一个400的错误，但我不知道在axios中使用async wait时如何从服务器获得完整的响应，在使用then和catch时它很容易显示出来，但我只能得到这个简单的响应。

当在控制台中打印正文/标题时，一切似乎都很好，这与我以前的请求相同，但由于某种原因，它在这里失败了。。。

Answer 1

使用async/await，这相对简单：

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

Answer 2

基本上，您需要让您的函数返回axios正在创建的Promise。很难判断样本的间距，但看起来只需在这行中添加一个return就可以了：

return axios(createAcc)

然后，您不需要使用setTimeout和循环，而是需要进行第一个调用，等待它完成，然后在then()方法中，如果您有一个调用，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"

我能用来解决这个问题的唯一解决方案是：

1. 使用For。。放置在异步函数中的in循环
2. 使用这种请求方式：const provisionResult=await axios(provision(
