我有这个网址模式
http://dev.virtualearth.net/REST/v1/Locations?
addressLine={0}&
adminDistrict={1}&
locality={2}&
countryRegion={3}&
postalCode={4}&
userLocation={5}&
inclnb=1&
key={6}
让我们这么说locality
并且userLocation
没有价值
http://dev.virtualearth.net/REST/v1/Locations?
addressLine=Main&
adminDistrict=WA&
locality=&
countryRegion=US&
postalCode=98001&
userLocation=&
inclnb=1&
key=BingKey
然后我想删除所有等于“ &
”的参数,
例如:' locality=&
'和' userLocation=&
'
应该是这样的:
http://dev.virtualearth.net/REST/v1/Locations?
addressLine=Main&
adminDistrict=WA&
countryRegion=US&
postalCode=98001&
inclnb=1&
key=BingKey
最终输出:
http://dev.virtualearth.net/REST/v1/Locations?addressLine=Main&adminDistrict=WA&countryRegion=US&postalCode=98001&inclnb=1&key=BingKey
