的NodeJS：如何使用异步/ AWAIT来处理HTTP请求油门的错误？

我米试图建立一个搜索API这需要的位置作为参数，并返回该位置的经度和纬度。我米使用。例如：/?locate=Warsaw,Poland&json=1这将返回该位置所需要的经度和纬度。

这是代码片段我有：

const url = '/?locate=Warsaw,Poland&json=1';
const getData = async url => {
try {
  const response = await fetch(url);
  const json = await response.json();
  console.log(json);
} catch (error) {
  console.log(error);
}
};
getData(url);

有了这个，这是我看到的错误：

node geocode.js
{success: false, error: { code: '006', message: 'Request Throttled.'}}

我猜的错误是因为我需要节流被击中API 。我不知道如何使用率限制器异步/等待。任何帮助，将不胜感激。

编辑：基于下面的答案，我仍然看到“请求经过调节”

var request = require('request');
const fetch = require("node-fetch");

const requester = {
    lastRequest: new Date(),
    makeRequest: async function(url) {
        // first check when last request was made
        var timeSinceLast = (new Date()).getTime() - this.lastRequest.getTime();
        if (timeSinceLast < 2000) {
            this.lastRequest = new Date(this.lastRequest.getTime() + (2000 - timeSinceLast));
            await new Promise(resolve => setTimeout(resolve, 2000-timeSinceLast));
          //  await new Promise(resolve => setTimeout(resolve, timeSinceLast));
        }
        const response = await fetch(url);
        const json = await response.json();
        return json;
    }
};
requester.makeRequest('/?locate=Warsaw,Poland&json=1')
.then(console.log)

我还在原地得到同样的错误：

{ success: false, error: { code: '006', message: 'Request Throttled.' } }

这是因为geocode pricing的？有什么办法来限制从用户端请求的速度？

也许你认为是用于发送所有请求了一个对象，该对象可以跟踪最后一次有人要求时的感觉。例如

const requester = {
    lastRequest: new Date(2000,0,1),
    makeRequest: async function (url) {
        // first check when last request was made
        var timeSinceLast = (new Date()).getTime() - this.lastRequest.getTime();
        this.lastRequest = new Date();
        if (timeSinceLast < 1000) {
            this.lastRequest = new Date(this.lastRequest.getTime() + (1000 - timeSinceLast));
            await new Promise(resolve => setTimeout(resolve, 1000-timeSinceLast));
        }

        // make request here and return result
        const response = await fetch(url);
        const json = await response.json();
        return json;
    }
};

如果你使用requester.request，它只是让你做一个请求，每秒一次，并等待足够长的时间（甚至连续请求）服从这个速度极限
