如何将Go语言HTTP请求返回的Unicode编码转换为可读的中文字符？

import (
    "encoding/json"
    "fmt"
    "log"
)

func convertUnicodeToChinese(unicodeString string) (string, error) {
    var data interface{}
    err := json.Unmarshal([]byte(unicodeString), &data) // 先将unicode字符串解析成JSON
    if err != nil {
        return "", fmt.Errorf("JSON unmarshal error: %w", err)
    }

    // 递归处理JSON数据结构，找到并转换Unicode字符串
    return convertUnicodeInJSON(data)
}


func convertUnicodeInJSON(data interface{}) (string, error) {
    switch v := data.(type) {
    case string:
        // 使用json.Unmarshal处理Unicode字符串
        var decodedString string
        err := json.Unmarshal([]byte(`"` + v + `"`), &decodedString)
        if err != nil {
            return "", fmt.Errorf("Unicode decoding error: %w", err)
        }
        return decodedString, nil
    case map[string]interface{}:
        result := make(map[string]interface{})
        for k, val := range v {
            convertedVal, err := convertUnicodeInJSON(val)
            if err != nil {
                return "", err
            }
            result[k] = convertedVal
        }
        jsonString, err := json.Marshal(result)
        if err != nil {
            return "", fmt.Errorf("JSON marshal error: %w", err)
        }
        return string(jsonString), nil
    case []interface{}:
        var result []interface{}
        for _, val := range v {
            convertedVal, err := convertUnicodeInJSON(val)
            if err != nil {
                return "", err
            }
            result = append(result, convertedVal)
        }
        jsonString, err := json.Marshal(result)
        if err != nil {
            return "", fmt.Errorf("JSON marshal error: %w", err)
        }
        return string(jsonString), nil
    default:
        return fmt.Sprintf("%v", data), nil
    }
}


func main() {
    headers := map[string]string{
        "user-agent": "test",
    }
    content, err := post("http://httpbin.org/post", headers, "")
    if err != nil {
        log.Fatal(err)
    }
    convertedContent, err := convertUnicodeToChinese(content)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(convertedContent)
}
