![PlaceResult]( "PlaceResult")
本文介绍了Google Maps API v3 Places库返回未定义的utc_offset的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在开发一个时间和位置感知应用程序，并且google maps v3 api库库几乎包含了我需要的所有内容。但是，当针对特定地址执行textSearch（）并尝试为其中一个返回的PlaceResult项目调用getDetails（）时，getDetails（）返回的PlaceResult.utc_offset属性未定义（我需要的所有其他PlaceResult属性均返回正确，而不是utc_offset）。
这很奇怪，因为如果我为像pizza这样的通用术语执行textSearch（），然后为返回的PlaceResult项目之一调用getDetails（），则PlaceResult从getDetails（）返回的.utc_offset属性将有一个值。
有谁知道为什么utc_offset是为通用搜索的结果填充的，但不是在搜索具体的地址，或者我做错了什么？ 解决方案
。我所做的是，如果它是未定义的，我打电话给Google TimeZone API来获取信息。我已经在下面提供了一个代码示例，但您也可以在GitHub上看到我的解决方案， p>
if（place.utc_offset === void 0）{
timeStamp =（Date.now（）|| new Date （）.getTime（））/ 1000;
timeZoneApiRequestUrl =https://maps.googleapis.com/maps/api/timezone/json?location=+
place.geometry.location.lat（）+，+ place.geometry .location.lng（）+
& timestamp =+ timeStamp +& key = YOUR_API_KEY
$ b $ .get（timeZoneApiRequestUrl，function（data）{
var utcOffset =（data.rawOffset + data.dstOffset || 0）/ 3600;
console.log（UTC offset is+ utcOffset +hours）
}）; / /扩大这个来处理错误，只是做一个成功的现在作为一个POC
}
I'm developing a time and location aware application and the google maps v3 api places library has almost everything I need. However, when doing a textSearch() for specific addresses, and attempting to call getDetails() for one of the returned PlaceResult items, the PlaceResult.utc_offset property returned from getDetails() is undefined (all the other PlaceResult properties I need are returned fine, just not the utc_offset).
It's strange, because if I do a textSearch() for a generic term like "pizza" and then call getDetails() for one of the returned PlaceResult items, the PlaceResult.utc_offset property returned from getDetails() will have a value.
Does anyone know why the utc_offset is populated for the results of a generic search, but not when searching for a specific address, or what am I doing wrong?
解决方案
As you mentioned in only works when there are generic terms like "pizza". What I've done is if it is undefined, I call the Google TimeZone API to get the info. I've put a code sample below, but you can see my solution on GitHub as well, https://github.com/pushpickup/pushpickup/blob/master/client/views/games/creategame/select-location.js#L13
if (place.utc_offset === void 0) {
timeStamp = (Date.now() || new Date().getTime())/1000;
timeZoneApiRequestUrl = "https://maps.googleapis.com/maps/api/timezone/json?location=" +
place.geometry.location.lat() + "," + place.geometry.location.lng() +
"×tamp=" + timeStamp + "&key=YOUR_API_KEY"
$.get(timeZoneApiRequestUrl, function( data ) {
var utcOffset = (data.rawOffset + data.dstOffset || 0) / 3600;
console.log("UTC offset is " + utcOffset + " hours")
}); // expand this to handle errors, just doing a get with success for now as a POC
}
