解码/解组复杂的嵌套 JSON 数据结构

php editor Strawberry introduces you to a powerful technique, which is to decode/unmarshal complex nested JSON data structures. In modern web applications, JSON data structures are widely used, but when the data structure becomes complex, it becomes difficult to parse and extract the required information. This article will share some practical tips and methods to help you easily cope with this challenge. Whether you are a beginner or an experienced developer, this article will provide you with valuable knowledge and practical tips. Let’s decode and unmarshal complex nested JSON data structures together!

Question content

I'm trying to process some JSON data returned from an API. However, it's not exactly a simple structure. It has a bunch of nested keys/values. I want to unmarshal it into a Go struct.

Is there an easy way to use go?

{ "http_buffered_trace": { "request": { "headers": [ { "key": ":authority", "value": "server.localhost:9443", "raw_value": "" }, { "key": ":path", "value": "/get_data", "raw_value": "" }, { "key": ":method", "value": "POST", "raw_value": "" }, { "key": ":scheme", "value": "https", "raw_value": "" }, { "key": "user-agent", "value": "curl/8.1.2", "raw_value": "" }, { "key": "content-length", "value": "1059", "raw_value": "" }, { "key": "accept", "value": "application/json", "raw_value": "" }, { "key": "authorization", "value": "auth data here ! ", "raw_value": "" }, { "key": "content-type", "value": "application/json", "raw_value": "" }, { "key": "x-forwarded-for", "value": "10.42.0.1", "raw_value": "" }, { "key": "x-forwarded-host", "value": "server.localhost:9443", "raw_value": "" }, { "key": "x-forwarded-port", "value": "9443", "raw_value": "" }, { "key": "x-forwarded-proto", "value": "https", "raw_value": "" }, { "key": "x-forwarded-server", "value": "traefik-64f55bb67d-6bbjl", "raw_value": "" }, { "key": "x-real-ip", "value": "10.42.0.1", "raw_value": "" }, { "key": "accept-encoding", "value": "gzip", "raw_value": "" }, { "key": "x-apache-internal", "value": "true", "raw_value": "" }, { "key": "x-request-id", "value": "995f0028-432e-499b-8bb9-c102834e150d", "raw_value": "" }, { "key": "x-apache-expected-rq-timeout-ms", "value": "15000", "raw_value": "" } ], "body": { "as_string": "Request body in here !", "truncated": false }, "trailers": [] }, "response": { "headers": [ { "key": ":status", "value": "200", "raw_value": "" }, { "key": "content-type", "value": "application/json; charset=UTF-8", "raw_value": "" }, { "key": "date", "value": "Wed, 01 Nov 2023 13:36:05 GMT", "raw_value": "" }, { "key": "x-apache-upstream-service-time", "value": "4", "raw_value": "" }, { "key": "server", "value": "envoy", "raw_value": "" } ], "body": { "as_string": "Response body in here!", "truncated": false }, "trailers": [] } } }

Solution

Here is a simple method:

type Header struct { Key string `json:"key"` Value string `json:"value"` RawValue string `json:"raw_value"` } type Trailer = Header type Body struct { Truncated bool `json:"truncated"` AsString string `json:"as_string"` } type Request struct { Headers []Header `json:"headers"` Body Body `json:"body"` Trailers []Trailer `json:"trailers"` } type Response = Request type HttpBufferedTrace struct { HttpBufferedTrace struct { Request Request `json:"request"` Response Response `json:"response"` } `json:"http_buffered_trace"` } func main() { h := HttpBufferedTrace{} json.Unmarshal([]byte(jsonStr), &h) fmt.Println(h) }
