在 NodeJS 中连接 GET 请求和 POST 请求

Question

我仍然是 NodeJS 的初学者，可供参考的资源很少。如何将这两个脚本连接在一起？

getproductinfo.js 对 API 端点执行 GET 请求并获取 Saveproductinfo.js 执行 POST 请求所需的所有数据并将所有信息保存到数据库 API.

getProductinfo.js

var axios = require('axios');

var config = {
  method: 'get',
  url: 'http://localhost:3001/api/get-products?keywords=shirt&min_sale_price=1&max_sale_price=100&page_no=1',
  headers: { }
};

axios(config)
.then(function (response) {
  console.log(JSON.stringify(response.data));
})
.catch(function (error) {
  console.log(error);
});

saveProductinfo.js

    var axios = require('axios');
var qs = require('qs');
var data = qs.stringify({
  'product_id': '1',
  'product_title': 'vxzvxzvxz',
  'promotion_link': 'vxzvxzvxz',
  'sale_price': 'vxzvxzvxz',
  'first_level_category_id': 'vxzvxzvxz',
  'second_level_category_id': 'vxzvxzvxz',
  'second_level_category_name': 'vxzvxzvxz',
  'first_level_category_name': 'vxzvxzvxz',
  'original_price_currency': 'vxzvxzvxz',
  'lastest_volume': 'vxzvxzvxz',
  'shop_url': 'vxzvxzvxz',
  'product_detail_url': 'vxzvxzvxz',
  'original_price': 'vxzvxzvxz',
  'product_main_image_url': 'vxzvxzvxz',
  'product_small_image_urls': 'vxzvxzvxz' 
});
var config = {
  method: 'post',
  url: 'http://localhost:3000/api/product',
  headers: { 
    'Content-Type': 'application/x-www-form-urlencoded'
  },
  data : data
};

axios(config)
.then(function (response) {
  console.log(JSON.stringify(response.data));
})
.catch(function (error) {
  console.log(error);
});

Answer 1

如果您导出 POST 函数以便可以在其他地方的代码中访问它，您应该能够调用 GET 并在 then() 回调中调用 post，像这样：

首先修改你的POST函数接受数据参数：

async function postFunction(data){
 axios(config)
 .then(function (response) {
  console.log(JSON.stringify(response.data));
  })
 .catch(function (error) {
  console.log(error);
});
}

然后用GET函数的结果调用它：

import <yourPostFunction>
var axios = require('axios');

const config = {
  method: 'get',
  url: 'http://localhost:3001/api/get-products?keywords=shirt&min_sale_price=1&max_sale_price=100&page_no=1',
  headers: { }
};

axios(config)
.then(function (response) {
  //GET function has finished running
  const result=JSON.stringify(response.data); //Might need to await this data
const postResult= await postFunction(result);//call your post function

})
.catch(function (error) {
  console.log(error);
});

你可以这样做：

var axios = require('axios');

var qs = require('qs');
var data = qs.stringify({
  'product_id': '1',
  'product_title': 'vxzvxzvxz',
  'promotion_link': 'vxzvxzvxz',
  'sale_price': 'vxzvxzvxz',
  'first_level_category_id': 'vxzvxzvxz',
  'second_level_category_id': 'vxzvxzvxz',
  'second_level_category_name': 'vxzvxzvxz',
  'first_level_category_name': 'vxzvxzvxz',
  'original_price_currency': 'vxzvxzvxz',
  'lastest_volume': 'vxzvxzvxz',
  'shop_url': 'vxzvxzvxz',
  'product_detail_url': 'vxzvxzvxz',
  'original_price': 'vxzvxzvxz',
  'product_main_image_url': 'vxzvxzvxz',
  'product_small_image_urls': 'vxzvxzvxz' 
});

var productDetails = {};
async function getProductInfo() {
  var config = {
    method: 'get',
    url: 'http://localhost:3001/api/get-products?keywords=shirt&min_sale_price=1&max_sale_price=100&page_no=1',
    headers: { }
  };
  try {
    const result = axios(config);
    productDetails = result;
  } catch (error) {
    console.error(error);
  }
}

async function Saveproductinfo() {
  // before creating config data you can 
  // create data using productDetails and then save it
 // taking values based on schema you shared in the comment
  data = qs.stringify({
  'product_id': '1',
  'product_title': productDetails[0].product_title,
  'promotion_link': 'productDetails[0].promotion_link',
  'sale_price': 'productDetails[0].sale_price',
  'first_level_category_id': 'productDetails[0].first_level_category_id', // do similary for all properties
  'second_level_category_id': 'vxzvxzvxz',
  'second_level_category_name': 'vxzvxzvxz',
  'first_level_category_name': 'vxzvxzvxz',
  'original_price_currency': 'vxzvxzvxz',
  'lastest_volume': 'vxzvxzvxz',
  'shop_url': 'vxzvxzvxz',
  'product_detail_url': 'vxzvxzvxz',
  'original_price': 'vxzvxzvxz',
  'product_main_image_url': 'vxzvxzvxz',
  'product_small_image_urls': 'vxzvxzvxz' 
});
  var config = {
    method: 'post',
    url: 'http://localhost:3000/api/product',
    headers: { 
      'Content-Type': 'application/x-www-form-urlencoded'
    },
    data : data
  };
  
  try {
    const results = await axios(config)
  } catch (e) {
    console.error(`Error is ${e}`);
  }
}

module.exports = {getProductInfo, Saveproductinfo}

现在，您有两种方法可以很好地进行单元测试。您可以使用 async/await.

顺序导入它们并运行它们

const {getProductInfo, Saveproductinfo } = require('filepath');

await getProductInfo(); // await here will work if node v14 >
await Saveproductinfo();
