地理编码客户端未向地理编码发送请求 api

Question

我正在尝试在 Firebase Cloud Function 上使用 Node.js 中的 google-maps-services javascript library。我希望从街道地址获取 (lat, lng)。出于测试目的，我是运行一个可调度的 firebase 函数，并从那里调用库函数。但是，只有我的错误路径被执行。以下是我使用的环境细节和代码片段

环境详情

平台：Node.js v8
地理编码API版本：2.0.2

重现步骤

运行一个从地理编码请求 (lat, lng) 的异步函数 api。函数体（index.js内部）在

下方

async function getDriverLocationNearAddress(streetAddress){
const geocodingClient = new Client({});
let params = {
        address: streetAddress,
        components: 'country:US',
        key: API_KEY_GEOCODING
    }; 
    console.log('retrieving lat, lng for ' + streetAddress);
    return geocodingClient.geocode(params)
    .then((response)=>{
        console.log('status: ' + response.data.status);
        console.log(response.data.results[0].geometry.location.lat);
        console.log(response.data.results[0].geometry.location.lng);
        return response;
    })
    .catch((error)=>{
        console.log('error retrieving geocoded results');
    });
}

已执行以下初始化

API_KEY_GEOCODING='*******************************'; // key not shown
const Client = require("@googlemaps/google-maps-services-js").Client;

我运行这个函数定期使用调度程序API每 1 分钟

exports.scheduledUpdateDriverLocations = functions.pubsub.schedule('every 1 minutes').onRun( (context) => {
    return getDriverLocationNearAddress('1042 Middlefield Rd, Redwood City, CA');
});

控制台日志显示我的 getDriverLocationsNearAddress 一直在触发 catch 语句，但没有在 then 部分打印任何日志。

但是，如果我尝试使用浏览器访问地理编码 API，它可以正常工作我的 google 云 api 控制台显示我没有收到任何 api 请求，除了使用浏览器发送的请求。在下图中，我只看到一个请求，尽管我每分钟发送一次请求，即在指定事件发生后的几分钟。

这是错误日志。看来我的请求格式不正确，但不确定为什么会这样

Answer 1

可能，我看到的是您无法从您的网络服务器调用 API（跨源请求）。找到您的网络服务器名称（例如 localhost:8080）并将其添加为授权的 javascript 来源。有关必须遵循的确切步骤的信息，您可以找到 here.

当您可以使用浏览器访问，但无法从 (javascript) 代码中访问 API 时，通常会出现这种情况。我还建议打印确切的错误而不是日志语句，或者只在 catch 块中打印两者。像这样：

.catch((error)=>{
    console.log('Error retrieving geocoded results: ' + error);
});

Answer 2

在运行来自 google-map-services library for node.js 的海拔高度 API 的最小示例之后，我能够弄清楚与如何向 [=12= 提供参数有关的问题] 函数。

我把node.js代码改成如下

之前：我没有提供字段名称params

async function getDriverLocationNearAddress(streetAddress){
const geocodingClient = new Client({});
let params = {
        address: streetAddress,
        components: 'country:US',
        key: API_KEY_GEOCODING
    }; 
    console.log('retrieving lat, lng for ' + streetAddress);
    return geocodingClient.geocode(params)
    .then((response)=>{
        console.log('status: ' + response.data.status);
        console.log(response.data.results[0].geometry.location.lat);
        console.log(response.data.results[0].geometry.location.lng);
        return response;
    })
    .catch((error)=>{
        console.log('error retrieving geocoded results');
    });
}

之后：

async function getDriverLocationNearAddress(streetAddress){
const geocodingClient = new Client({});
let params = {
        address: streetAddress,
        components: 'country:US',
        key: API_KEY_GEOCODING
    }; 

    console.log('retrieving lat, lng for ' + streetAddress);
    geocodingClient.geocode({
        params:params
    })
    .then((response)=>{
        console.log('status: ' + response.data.status);
        console.log(response.data.results[0].geometry.location.lat);
        console.log(response.data.results[0].geometry.location.lng);
        return response;
    })
    .catch((error)=>{
        console.log('error retrieving geocoded results');
    });
}
