使用WooCommerce REST API获取商品详情返回异常，请求排查问题

Let’s walk through exactly what’s wrong with your current request and how to fix it:

• Missing Resource Endpoint
  WooCommerce REST API v3 requires you to specify which resource you’re targeting. Your URL only ends at wc-api/v3 — there’s no indication that you want product data! You need to add the /products endpoint (for a product list) or /products/{product_id} (for a single specific product) to tell the API what data to return.

• Incorrect Field Selection Format
  You’re trying to specify fields by listing them as top-level parameters (id&name&...), but that’s not how WooCommerce API works. To filter returned fields, you need to use the fields parameter with a comma-separated list of field names. Your current approach makes the API treat each field name as a separate parameter with no value, which it can’t parse correctly.

• Invalid URL Encoding for Ampersands
  The & in your URL is an HTML entity. For API requests, you should use raw & characters to separate parameters. While some clients might auto-convert this, using & directly can cause the API to misinterpret your parameter list.

• Potential Missing Authentication
  WooCommerce REST API requires authentication (either OAuth 1.0a or Basic Auth) to access product data. If you haven’t included authentication headers or credentials in your request, the API will likely return empty or unauthorized responses even if the URL is fixed.

Example of a Corrected Request URL #

For fetching a list of products with your desired fields:

https://squatwolf.com/wp-json/wc/v3/products?fields=id,name,permalink,short_description,price,sale_price

For fetching a single product (replace {product_id} with the actual ID):

https://squatwolf.com/wp-json/wc/v3/products/{product_id}?fields=id,name,permalink,short_description,price,sale_price

Note: Make sure you’re using the correct API base path — wp-json/wc/v3 is the standard for WooCommerce REST API v3, whereas wc-api/v3 refers to the older Legacy API which has different syntax.
