首先在这里向您提供帮助！这是一个很好的地方，可以学到很多东西！
我的问题：我想从一个地址返回地理坐标。喜欢这里：https://www.myengineeringworld.net/2014/06/geocoding-using-vba-google-api.html
我创建了一个API密钥，这个代码运行良好！但我们有一个防火墙，防火墙在"request.send"点上阻止Excel与谷歌地图服务器的通信(我找不到IP范围或你可以放在白名单上的东西(，你的浏览器有机会获取XML代码吗？因为我可以使用"Request.Open"GET中的链接，并且我可以在Internet Explorer中看到XML内容。除了请求，还有其他方法吗？发送
谢谢你们！
代码：
Function GetCoordinates(Address As String) As String
'-----------------------------------------------------------------------------------------------------
'This function returns the latitude and longitude of a given address using the Google Geocoding API.
'The function uses the "simplest" form of Google Geocoding API (sending only the address parameter),
'so, optional parameters such as bounds, language, region and components are NOT used.
'In case of multiple results (for example two cities sharing the same name), the function
'returns the FIRST OCCURRENCE, so be careful in the input address (tip: use the city name and the
'postal code if they are available).
'NOTE: As Google points out, the use of the Google Geocoding API is subject to a limit of 40,000
'requests per month, so be careful not to exceed this limit. For more info check:
'https://cloud.google.com/maps-platform/pricing/sheet
'In order to use this function you must enable the XML, v3.0 library from VBA editor:
'Go to Tools -> References -> check the Microsoft XML, v3.0.
'If you don't have the v3.0 use any other version of it (e.g. v6.0).
'2018 Update: In order to use this function you will now need a valid API key.
'Check the next link that guides you on how to acquire a free API key:
'https://www.myengineeringworld.net/2018/02/how-to-get-free-google-api-key.html
'2018 Update 2 (July): The EncodeURL function was added to avoid problems with special characters.
'This is a common problem with addresses that are from Greece, Serbia, Germany and other countries.

结束函数
您可以尝试检测代理设置并将其添加到XMLHTTP请求中。
