推荐答案

查看您的帐户，看来没有任何数据源可通过

Taking a look into your account it doesn't look like there is any data source that can be accessed at

http://spatial.virtualearth.net/REST/v1/数据/20181f26d9e94c81acdf9496133d4f23/petrolbunk/petrolbunk

您是否创建了数据源?如果有，请在Bing Maps门户中，转至数据源"->查看数据源"信息.找到您要访问的数据源并复制完整的URL(您无需将其分解为多个部分，即accessId，数据源名称，实体名称).

Have you created a data source? If you have, in the Bing Maps portal, go to Data Sources -> View Data source information. Find the data source you want to access and copy the complete URL (you don't need to break it up into pieces i.e. accessId, data source name, entity name).

如果要访问Bing Maps中的兴趣点数据源之一，请查看NAVTEQNA数据源:

If you want to access one of the point of interest data sources in Bing Maps, then take a look at the NAVTEQNA data source: https://msdn.microsoft.com/en-us/library/hh478192.aspx
