我正在使用Google Places API標記兩個地點之間的路線。它對大多數路線都很好。但是，它不是爲少數路線標記路線。這是因爲「directionsService.route」請求正在爲某些路由返回「ZERO_RESULTS」狀態。下面是它不工作的輸入之一。Google Places API不標記某些地方的路線
源A：
South End Circle, Basavanagudi, Bangalore, Karnataka, India
目的地B：
Jayanagar 4 Block, Jayanagar, Bangalore, Karnataka, India
中間點C：
Tata Silk Farm, Jayanagar, Bangalore, Karnataka, India
下面是代碼：

下面是我所得到的，當我給上述地區的快照： 
它並不標誌着路線。可能是什麼問題呢？
有什麼問題嗎？ –
這些位置給了我一個結果。 – geocodezip
@geocodezip我已經更新了快照和完整代碼的問題。對於我在問題中給出的路線，它仍然沒有標記路線（對我來說）。 –
