[英]Google Apps Script OAuth2 Library Error for Service Accounts if private Key is not stored in apps script file directly
[英]Supply API key to avoid Hit Limit error from Maps Service in Apps Script
我有一個Google表格,可以通過Maps Service獲取兩個緯度/經度之間的行駛距離。 下面的函數有效,但是矩陣是4,500個單元格,因此出現“命中限制”錯誤。
如何在此處提供我的付費帳戶的API密鑰?
自定義功能
function drivingMeters(origin, destination) {
if (origin=='' || destination==''){return ''}
var directions = Maps.newDirectionFinder()
.setOrigin(origin)
.setDestination(destination)
.getDirections();
return directions.routes[0].legs[0].distance.value ;
}
使用示例:
A1: =drivingMeters($E10,G$9)
Where E10 = 42.771328,-91.902281
and G9 = 42.490390,-91.1626620
根據文檔,您應在調用其他方法之前使用身份驗證詳細信息初始化Maps服務 :
您的客戶ID和簽名密鑰可以從Google Enterprise支持門戶獲取。 將這些值設置為
null
可返回使用默認配額限額。
我建議將這些值存儲在PropertiesService
並使用CacheService
來提供快速訪問。 使用這種方法,而不是在腳本項目的主體中編寫它們,意味着如果您的腳本以庫的形式發布,它們將不會被其他編輯器無意復制,推送到共享代碼存儲庫或其他開發人員可見。
此外,我建議重寫自定義函數以接受數組輸入並返回適當的數組輸出-這將有助於加快其執行速度。 Google在自定義功能頁面上提供了一個示例: https : //developers.google.com/apps-script/guides/sheets/functions#optimization
使用道具/緩存的示例:
function authenticateMaps_() {
// Try to get values from cache:
const cache = CacheService.getScriptCache();
var props = cache.getAll(['mapsClientId', 'mapsSigningKey']);
// If it wasn't there, read it from PropertiesService.
if (!props || !props.mapsClientId || !props.mapsSigningKey) {
const allProps = PropertiesService.getScriptProperties().getProperties();
props = {
'mapsClientId': allProps.mapsClientId,
'mapsSigningKey': allProps.mapsSigningKey
};
// Cache these values for faster access (max 6hrs)
cache.putAll(props, 21600);
}
// Apply these keys to the Maps Service. If they don't exist, this is the
// same as being a default user (i.e. no paid quota).
Maps.setAuthentication(props.mapsClientId, props.mapsSigningKey);
}
function deauthMaps_() {
Maps.setAuthentication(null, null);
}
// Your called custom function. First tries without authentication,
// and then if an error occurs, assumes it was a quota limit error
// and retries. Other errors do exist (like no directions, etc)...
function DRIVINGMETERS(origin, dest) {
if (!origin || !destination)
return;
try {
return drivingMeters_(origin, dest);
} catch (e) {
console.error({
message: "Error when computing directions: " + e.message,
error: e
});
// One of the possible errors is a quota limit, so authenticate and retry:
// (Business code should handle other errors instead of simply assuming this :) )
authenticateMaps_();
var result = drivingMeters_(origin, dest);
deauthMaps_();
return result;
}
}
// Your implementation function.
function drivingMeters_(origin, dest) {
var directions = Maps.newDirectionFinder()
...
}
