问题
What's wrong with this request? I cannot come up with this issue.
https://maps.googleapis.com/maps/api/place/nearbysearch/json?rankby=distance&location=49.4456945,10.1120762&language=IT&sensor=true&key=my-api-key
If I delete the rankby parameter and add radius, it works.
PS: instead of my-api-key there is a valid api key, declared in the console.
回答1:
As the documentation states under 'Optional parameters > rankby > distance', "One or more of keyword, name, or types is required." Add one or more of those parameters to your request and the server will send an OK response.
回答2:
As pushbit say,
If rankby=distance is specified, then one or more of keyword, name, or types is required.
If you want to retieve each place use "type=establishment"
https://maps.googleapis.com/maps/api/place/nearbysearch/json?types=establishment&rankby=distance&location=49.4456945,10.1120762&language=IT&sensor=true&key=your-key
回答3:
rankby — Specifies the order in which results are listed. Note that rankby must not be included if radius (described under Required parameters above) is specified.

回答4:
If you use rankby=distance, you need to add at least name or types. I suggest to add types=point_of_interest.
Ps: types=establishment is deprecated, see: Place Types for more details.
回答5:
&key=my-api-key
You need to add API_KEY from Google API console
