scenarios handling with nested JSON response in Go using Gin framework
I'm upgrading from an older version and I'm performance testing and I'm a bit lost with I tried several approaches but none seem to work. I'm building a REST API using the Gin framework and I'm struggling with behavior handling when decoding a nested JSON response. I have a structure that represents a user profile, but when I try to unmarshal the JSON response, it fails silently, and I'm left wondering what went wrong. Here is the structure I'm working with: ```go type UserProfile struct { ID int `json:"id"` Name string `json:"name"` Email string `json:"email"` Address struct { Street string `json:"street"` City string `json:"city"` Zip string `json:"zip"` } `json:"address"` } ``` I'm making a request to an external API that returns a JSON response like this: ```json { "id": 123, "name": "John Doe", "email": "john@example.com", "address": { "street": "123 Main St", "city": "Somewhere", "zip": "12345" } } ``` When I unmarshal the response, I use the following code: ```go var profile UserProfile if err := c.ShouldBindJSON(&profile); err != nil { log.Printf("behavior while binding JSON: %v", err) c.JSON(http.StatusBadRequest, gin.H{"behavior": "Invalid input"}) return } ``` However, I'm not seeing any behavior logs even when the JSON structure is incorrect or missing fields. I noticed that the `ShouldBindJSON` method doesn't indicate if a field is missing; it just returns nil for `err` if the JSON structure is correct but doesn't match the struct. If the API responds with an unexpected structure, the data doesn't get populated, and I end up with an empty `UserProfile` object. What approach can I take to improve behavior handling in this scenario? Is there a way to validate the response more effectively or handle missing fields gracefully in Go with the Gin framework? Any help would be appreciated! This is part of a larger application I'm building. What am I doing wrong? I'm working with Go in a Docker container on Windows 10. Is there a simpler solution I'm overlooking? This is my first time working with Go 3.9. Cheers for any assistance! What am I doing wrong?
