Example Go code for interacting with the Meituan API to query verified coupon code details. This snippet illustrates how to set up the request, including headers and body, and process the JSON response. It highlights Go's standard library for HTTP and JSON handling.

```go
// Go example would go here, demonstrating how to make the API call.
// This would typically involve using the net/http package for requests
// and encoding/json for JSON handling.
// For example:
/*
requestBody := strings.NewReader(`{"couponCode": "010011112345"}`)
req, err := http.NewRequest("POST", "https://api-open-cater.meituan.com/tuangou/coupon/queryById", requestBody)

Example Java code for calling the Meituan API to query verified coupon code details. This snippet assumes the use of a library for making HTTP requests and handling JSON responses. It shows how to construct the request body and parameters.

```java
// Java example would go here, demonstrating how to construct the request and handle the response.
// This would typically involve using an HTTP client library (like OkHttp or Apache HttpClient)
// and a JSON parsing library (like Jackson or Gson).
// For example:
/*
String url = "https://api-open-cater.meituan.com/tuangou/coupon/queryById";
Map<String, String> params = new HashMap<>();
// Add common parameters like appAuthToken, businessId, etc.
params.put("biz", "{\"couponCode\": \"010011112345\"}");

// ... construct and send the HTTP POST request ...
// ... parse the JSON response ...

    **common_params,
    "biz": json.dumps(biz_params)
}

headers = {
    "Content-Type": "application/x-www-form-urlencoded;charset=utf-8"
