问题:

With the google places api, it is possible to get details related to user reviews of a place. Looking at the documentation and it seems that I can get the following details:

rating: 0-5 based on user rates and this is the average of all submitted reviews
last 5 user ratings

However, there doesn't seem to be any reference to

total number of reviews
count total for each rating ie, 5/5: 5 reviews, 4/5: 23 reviews, ...

Anyone have an idea on where to get this information?

回答1:

There is a new, yet to be documented, details result key user_ratings_total. I believe this is the number of ratings that have contributed to the overall rating.

I don't believe the API currently provides count totals for each rating value. You could request this enhancement (if it hasn't been already) at gmaps-api-issues.

it is possible now to get total number of reviews using Place Details Place APIs call: https://developers.google.com/places/web-service/details#fields

as of Jan 2019, it returns user_ratings_total field: https://developers.google.com/maps/documentation/javascript/releases#335
