在GET请求依赖于POST请求的地方发出http请求

Question

我目前正在节点中处理一个项目，我应该首先发送POST请求，然后发送GET请求，该请求取决于POST请求的响应。有人对此有什么建议吗？我在用axios和express。异步/同步的事情让我很紧张。

我的代码

const express = require("express");
const PORT = process.env.PORT || 3000;
var axios = require("axios");
const app = express();
app.set("view engine", "ejs");
app.use(express.static("Public"));
var url1 = "https://api.playground.klarna.com/checkout/v3/orders/";
var url2 = "https://api.playground.klarna.com/checkout/v3/orders/";
//POST
var axios = require("axios");
var data = JSON.stringify({
purchase_country: "SE",
purchase_currency: "SEK",
locale: "sv-SE",
order_amount: 50000,
order_tax_amount: 4545,
order_lines: [
{
type: "physical",
reference: "19-402-USA",
name: "Red T-Shirt",
quantity: 5,
quantity_unit: "pcs",
unit_price: 10000,
tax_rate: 1000,
total_amount: 50000,
total_discount_amount: 0,
total_tax_amount: 4545,
},
],
merchant_urls: {
checkout:
"https://atelierdecosmetique.herokuapp.com/checkout?sid={checkout.order.id}",
confirmation:
"https://atelierdecosmetique.herokuapp.com/confirmation?sid={checkout.order.id}",
push: "https://www.example.com/api/push",
},
});
var config = {
method: "post",
url: url1,
headers: {
"Content-Type": "application/json",
Authorization:
"",
},
data: data,
};
//GET
var axios = require("axios");
var data1 = "";
var config1 = {
method: "get",
url:
url2,
headers: {
"Content-Type": "application/json",
Authorization:
"",
},
data: data1,
};


axios(config)
.then(response => {

return axios(config1)
}).then(response => {

})
.catch(err => console.log(err))


app.listen(PORT);

由于您没有显示任何代码，我们只能从概念上回答。由于promise最容易使用async/await进行排序，所以我选择在这里向您展示的模型是：

async function someFunction() {
const postResult = await axios.post(someUrl, someData);
const getResult = await axios.get(someUrl2, {params: {can use postResult in here}});
// further processing
return something;
}
// call it like this
somefunction().then(finalResult => {
console.log(finalResult);
}).catch(err => {
console.log(err);
});

如果您显示实际代码，我们可以显示更多详细信息。
