我有两个文件; server.js和scrape.js,下面是他们目前的代码片段.

server.js:

const scrape = require("./scrape");

async function start() {
    const response = await scrape.start();
    console.log(response);
}

start();

和scrape.js:

const cheerio = require("cheerio");
const request = require("request-promise");

go = async () => {

const options = {
  uri: "http://www.somewebsite.com/something",
  transform: function(body) {
    return cheerio.load(body);
  }
};

request(options)
  .then($ => {
    let scrapeTitleArray = [];
    $(".some-class-in-html").each(function(i, obj) {
      const data = $(this)
        .text()
        .trim();
      scrapeTitleArray.push(data);
    });
    return scrapeTitleArray;
  })
  .catch(err => {
    console.log(err);
  });
};

module.exports = {
  start: go …

目前正在尝试使用 fixer.io API 在 C# 中创建货币转换。

我在从 Twitter API 解析 JSON 时使用了与下面类似的方法，并且没有任何问题，我不完全确定这里发生了什么。

从 API 返回的 JSON 示例：
