解析HTTP响应中的复杂JSON数据
来源：stackoverflow
时间：2024-03-26 18:57:35 354浏览 收藏
本文介绍了如何解析包含复杂 JSON 数据的 HTTP 响应。该 JSON 数据具有多层嵌套结构，包括列表和映射。为了从该 JSON 数据中提取特定信息，可以使用自定义函数 `findNested` 来递归地遍历映射并查找指定的键。`findNested` 函数会返回一个布尔值，指示该键是否找到，以及找到的值。利用此函数，可以轻松地提取所需字段，例如每个站点的 site_id、ip 和域名。

api 文档：https://docs.imperva.com/bundle/cloud-application-security/page/api/sites-api.htm#list
对于我来说，理解 go 似乎非常痛苦，因为我才刚刚开始。 从我读到的内容来看，我应该用我期望的格式定义一个 struct 类型的对象。 有什么办法可以让我更轻松地解决这个问题吗？我有兴趣为每个单独的站点提取一些项目，例如 site_id / ips / 域。
不确定我应该如何解决这个问题。我一直在尝试了解 https://github.com/buger/jsonparser 但我无法真正理解如何使用它。
到目前为止我一直在做的是：
func main() {
fmt.Println("Starting this..")
formData := url.Values{
"api_id": {keyid},
"api_key": {apikey},
"page_size": {"100"},
"page_num": {"0"},
}
response, err := http.PostForm("https://my.imperva.com/api/prov/v1/sites/list", formData)
if nil != err {
fmt.Println("Ooops..", err)
}
log.Println(response.Status)
bodyBytes, err := ioutil.ReadAll(response.Body)
if err != nil {
log.Fatal(err)
}
var results map[string]interface{}
fmt.Println(string(bodyBytes))
json.Unmarshal([]byte(bodyBytes), &results)
defer response.Body.Close()
}解决方案
如果您只需要提取几个字段，则实际上不需要定义复杂的 struct 类型来描述整个结构。您可以使用 stdlib 将 json 解组到 map[string]interface{}，然后使用类似此函数的功能来查找有趣的键：
// findNested looks for a key named s in map m. If values in m map to other
// maps, findNested looks into them recursively. Returns true if found, and
// the value found.
func findNested(m map[string]interface{}, s string) (bool, interface{}) {
// Try to find key s at this level
for k, v := range m {
if k == s {
return true, v
}
}
// Not found on this level, so try to find it nested
for _, v := range m {
nm, ok := v.(map[string]interface{})
if ok {
found, val := findNested(nm, s)
if found {
return found, val
}
}
}
// Not found recursively
return false, nil
}
此代码仅处理嵌套映射。您可以稍微调整它以透视切片等。
