Question
Answer and Explanation
When integrating a Spring Boot application with Yahoo services, such as using Yahoo Finance API or other Yahoo APIs, the application.properties file requires specific configuration options. These options typically pertain to API keys, OAuth settings, and other connection details. Here's a breakdown of the common configuration properties you might encounter:
1. API Keys and Credentials:
- If you are using a Yahoo API that requires an API key, you'll need to store this in the configuration. This ensures that your application can authenticate with Yahoo’s services. Example:
yahoo.api.key=YOUR_YAHOO_API_KEY
2. OAuth 2.0 Configuration:
- For services that use OAuth 2.0, you'll need the client ID, client secret, authorization URI, token URI, and redirect URI. These are necessary to get tokens required to call the Yahoo API. Example:
yahoo.oauth2.client.id=YOUR_CLIENT_ID
yahoo.oauth2.client.secret=YOUR_CLIENT_SECRET
yahoo.oauth2.authorization.uri=https://api.login.yahoo.com/oauth2/request_auth
yahoo.oauth2.token.uri=https://api.login.yahoo.com/oauth2/get_token
yahoo.oauth2.redirect.uri=http://localhost:8080/oauth2/callback
3. Yahoo API Endpoints:
- The base URL or specific endpoints of the Yahoo APIs you intend to use. Example:
yahoo.api.base.url=https://query1.finance.yahoo.com/v7/finance/
yahoo.api.quotes.endpoint=/quote
4. Connection Settings (Optional):
- If you have specific connection parameters for making requests, you can configure timeouts, connection pool sizes etc. Example:
yahoo.api.connection.timeout=5000
yahoo.api.read.timeout=10000
5. Other Yahoo Specific Configurations:
- Other parameters related to specific Yahoo API like the region, language etc. Example:
yahoo.api.region=US
Example of a full application.properties with these configurations:
yahoo.api.key=YOUR_YAHOO_API_KEY
yahoo.oauth2.client.id=YOUR_CLIENT_ID
yahoo.oauth2.client.secret=YOUR_CLIENT_SECRET
yahoo.oauth2.authorization.uri=https://api.login.yahoo.com/oauth2/request_auth
yahoo.oauth2.token.uri=https://api.login.yahoo.com/oauth2/get_token
yahoo.oauth2.redirect.uri=http://localhost:8080/oauth2/callback
yahoo.api.base.url=https://query1.finance.yahoo.com/v7/finance/
yahoo.api.quotes.endpoint=/quote
yahoo.api.connection.timeout=5000
yahoo.api.read.timeout=10000
yahoo.api.region=US
In a real Spring Boot application, these values would typically be injected into a Spring component using @Value annotations. It is highly recommended to store sensitive information like API keys and client secrets in environment variables or secure vaults, rather than directly in the properties file.
