Rails 4集成Google：无需认证在网页展示评论可行吗？

Great question—you’re right that most Google admin-focused auth methods are overkill for just showing public reviews. Here are two straightforward, no-admin-account-needed approaches:

1. Embed Google’s Official Review Widget (No Code/API Required) #

This is the simplest option by far. Google lets you embed a fully functional map card for any business that includes public reviews, no authentication of any kind required:

• Go to Google Maps, search for the business you want to display reviews for.
• Click the Share button (usually near the top of the business page).
• Select the Embed a map tab, choose your preferred size, then copy the generated HTML code.
• Paste that code directly into your webpage’s source. The embedded card will automatically show public reviews, and users can interact with them just like on Google Maps.

2. Use the Google Places API (With a Free API Key, No Admin Account) #

If you need more control over how reviews are styled or displayed (instead of using Google’s pre-built widget), the Places API works for public review data—you only need a basic API key (not a Google Admin account):

• Head to the Google Cloud Console, create a new project (free to start), then enable the Places API for that project.
• Generate a standard API key (no OAuth or admin permissions needed).
• Use the Place Details endpoint to fetch reviews. Here’s a sample request structure:

  GET https://maps.googleapis.com/maps/api/place/details/json?place_id=YOUR_BUSINESS_PLACE_ID&fields=reviews&key=YOUR_API_KEY
  

• You can find the business’s place_id by searching for it on Google Maps, then checking the URL or using the Places API’s Text Search endpoint to look it up programmatically.

Important note: The Places API has a free usage tier, so you won’t get charged unless you exceed the monthly limit. And again—this doesn’t require any access to a Google Admin account, since you’re only accessing public, non-restricted data.
