如何判断Google的Streetview图像API是否返回“对不起，我们这里没有图像” （即NULL）结果？ [英] How can I tell if Google's Streetview Image API Returns "Sorry, we have no imagery here" (ie. NULL) Result?
问题描述
Google街景视图图像API 可让您嵌入静态（非交互式）街景全景或缩略图到您的网页，而不使用JavaScript。

+问题+
如果我给它一个地址它没有Streetview，它会返回一个图片，上面写着对不起，我们这里没有图片。
基于当前的API，我无法检测是否找到了街景视图。任何人都有一个黑客或建议，以弄清楚这一点？
+示例+

基本上，您需要做的是创建一个StreetViewService对象，该对象将尝试根据位置查找全景图，使用 getPanoramaByLocation（latlng：LatLng，radius：number，callback：function（StreetViewPanoramaData，StreetViewStatus））方法。 >在回调函数中，有一个条件参数将检查数据可用性 if（status == google.maps.StreetViewStatus.OK）。基于布尔返回，执行所需的操作。我提供的第一个链接是使用这些方法的一个很好的例子。
注意：我还注意到您有基于地址的位置。这可以使用地理编码服务简单地转换为LatLng（ https://developers.google.com / maps / documentation / javascript / geocoding ）
The Google Street View Image API lets you embed a static (non-interactive) Street View panorama or thumbnail into your web page, without the use of JavaScript.

+The Problem+
If I give it an address for which it doesn't have a Streetview, it returns an image that says, "Sorry, we have no imagery here".
Based on the current API, I have no way of detecting if it found a Streetview or not. Anyone have a hack or suggestion for figuring this out?
+Examples+
Proper Streetview: http://maps.googleapis.com/maps/api/streetview?size=300x300&sensor=false&location=100+Highland+Ave+Baltimore,+MD+21224
Sorry Streetview: http://maps.googleapis.com/maps/api/streetview?size=300x300&sensor=false&location=1600+Pennsylvania+Ave,+Washington,+DC+20500
Consider using StreetViewService and StreetViewStatus objects in Google Maps: https://developers.google.com/maps/documentation/javascript/streetview#StreetViewService
Essentially what you'll have to do is create a StreetViewService object that will try to find a panorama based on location, using the getPanoramaByLocation(latlng:LatLng, radius:number, callback:function(StreetViewPanoramaData, StreetViewStatus)) method.
In the callback function, have a conditional argument that will check for the data availability if (status == google.maps.StreetViewStatus.OK). Based on the boolean return, execute the desired actions. The first link I provided got a great example of the use of these methods.
Note: I also notice you've got locations based on addresses. This can be simply converted to LatLng using the Geocoding Service ( https://developers.google.com/maps/documentation/javascript/geocoding )
