無效的鄰居請求

Question

我發送的請求是這樣的：

https://maps.googleapis.com/maps/api/place/search/json?radius=30&location=37.7858742105946,-122.406341359019&rankby=distance&key=MYKEYHERE&type=establishment

但響應回來，因爲這：

{ 
    "html_attributions" : [], 
    "results" : [], 
    "status" : "INVALID_REQUEST" 
} 

什麼是錯我的要求就是它造成無效？

Answer 1

從文檔：

半徑 - 定義其範圍內返回地方結果的距離（以米爲單位）。允許的最大半徑是50000米。注意，如果指定了rankby = distance（在下面的可選參數下描述），則不得包含半徑。

從請求中刪除rankby=distance（對於30米半徑，它沒有任何意義）。

https://maps.googleapis.com/maps/api/place/search/json?radius=30&location=37.7858742105946,-122.406341359019&key=<KEY>&type=establishment
