// Authorization: <schema> <token> $url_parts = parse_url($url); $canonical_url = ($url_parts['path'] . (!empty($url_parts['query']) ?

这段代码看起来像是一个使用OpenSSL对HTTP请求进行签名的过程，其中包括了HTTP请求方法、请求路径、时间戳、随机字符串、请求体等信息，以及商户的私钥和证书序列号等参数。这个过程可能是为了保证请求的安全性和可靠性，防止请求被篡改或伪造。这是针对微信支付的，有关微信支付更多的信息可以参考微信支付官方文档。

在GoFrame 2.4.3框架中，你可以重写代码如下：

package controller

import (
    "github.com/gogf/gf/v2/encoding/gjson"
    "github.com/gogf/gf/v2/frame/g"
    "github.com/gogf/gf/v2/net/ghttp"
)

type AudienceController struct{}

func (c *AudienceController) GetAudiencePackage(r *ghttp.Request) {
    url := "https://ad.oceanengine.com/open_api/2/audience_package/get/"
    filtering := g.Map{
        "landing_type":   r.Get("landing_type"),
        "delivery_range": r.Get("delivery_range"),
        "ad_type":        "ALL",
    }
    data := g.Map{
        "advertiser_id": 1748895409387534,
        "page":          r.Get("page"),
        "page_size":     r.GetInt("page_size"),
        "filtering":     filtering,
    }
    for k, v := range data {
        if !gconv.IsString(v) {
            data[k] = gjson.New(v).MustToJsonString()
        }
    }
    requestURL := url + "?" + ghttp.BuildQuery(data)
    token := "01c0dd4bef2fc5a2c38eac3f07eb1915bb338a7f"
    client := ghttp.NewClient()
    response, err := client.SetHeader("Authorization", "Bearer "+token).Get(requestURL)
    if err != nil {
        g.Log().Error(err)
        r.Response.WriteJson(g.Map{
            "code":    -1,
            "message": "Request failed",
            "data":    nil,
        })
        return
    }
    list := gjson.New(response.ReadAllString()).MustToJson()
    r.Response.WriteJson(g.Map{
        "code":    0,
        "message": "Request success",
        "data":    list,
    })
}

以上代码是一个AudienceController的示例，你可以将其添加到goframe2.4.3框架的控制器中。在该示例中，我们使用`ghttp`包发送HTTP请求，`gjson`包处理JSON数据，`g`包提供了日志记录功能。

请注意，你可能需要根据实际情况调整代码中的导入语句和其他细节，以适应你的项目。

public function handle(array $arrParam = []) { $arrDeveloper = $this->getDeveloper($this->intAdvChannel); $strClientId = $arrDeveloper['client_id']; $strClientSecret = $arrDeveloper['client_secret']; $strCode = $arrParam['authorization_code'] ?? ''; $intAdvertiserRole = $arrParam['state'] ?? 2; $arrRequestData = [ 'client_id' => $strClientId, 'client_secret' => $strClientSecret, 'grant_type' => 'authorization_code', 'authorization_code' => $strCode, 'redirect_uri' => sprintf($this->getAuthCallbackUri(), Enum::GDT), //传入的地址需要与获取 authorization_code 时，传入的回调地址保持一致 ]; $arrOption = [ RequestOptions::QUERY => $arrRequestData, 'method' => 'GET', ]; $arrSelfResponse = Utils::doRequest($this->strAccessTokenUrl, $arrOption); if ($arrSelfResponse['code'] != 200) { return $this->errorArr($arrSelfResponse['code'], $arrSelfResponse['msg']); } $arrResponse = $arrSelfResponse['data'] ?? []; if (!isset($arrResponse['code']) || $arrResponse['code'] != 0) { Log::get($this->strChannelName)->error($this->strChannelName . "-获取access_token失败", [ 'url' => $this->strAccessTokenUrl, 'request' => $arrRequestData, 'response' => $arrResponse ]); return $this->errorArr(ErrorCode::OAUTH_GET_ACCESS_TOKEN_FAIL, $arrResponse['message']); } $arrAccessToken = $arrResponse['data']; $result = $this->setOAuthToken($arrAccessToken, $intAdvertiserRole, $arrParam['auth_request_id']); if ($result) { return $this->successArr(); } return $this->errorArr(); }在goframe框架中实现以上代码

在 GoFrame 框架中，可以在某个控制器中创建一个 handle 方法，并将代码放入其中，例如：

func (c *Controller) handle(r *ghttp.Request) {
	arrDeveloper := c.getDeveloper(c.intAdvChannel)
	strClientId := arrDeveloper["client_id"].(string)
	strClientSecret := arrDeveloper["client_secret"].(string)
	strCode := r.GetString("authorization_code", "")
	intAdvertiserRole := r.GetInt("state", 2)
	arrRequestData := g.Map{
		"client_id":       strClientId,
		"client_secret":   strClientSecret,
		"grant_type":      "authorization_code",
		"authorization_code": strCode,
		"redirect_uri":    fmt.Sprintf(c.getAuthCallbackUri(), Enum.GDT),
	}
	arrOption := ghttp.RequestOptions{
		Query:  arrRequestData,
		Method: "GET",
	}
	arrSelfResponse := Utils.doRequest(c.strAccessTokenUrl, arrOption)
	if arrSelfResponse["code"].(int) != 200 {
		c.jsonErrorArr(arrSelfResponse["code"].(int), arrSelfResponse["msg"].(string))
	}
	arrResponse := arrSelfResponse["data"].(g.Map)
	if _, ok := arrResponse["code"]; !ok || arrResponse["code"].(int) != 0 {
		g.Log().Error(c.strChannelName + "-获取access_token失败", g.Map{
			"url":      c.strAccessTokenUrl,
			"request":  arrRequestData,
			"response": arrResponse,
		})
		c.jsonErrorArr(ErrorCode.OAUTH_GET_ACCESS_TOKEN_FAIL, arrResponse["message"].(string))
	}
	arrAccessToken := arrResponse["data"].(g.Map)
	result := c.setOAuthToken(arrAccessToken, intAdvertiserRole, r.GetString("auth_request_id", ""))
	if result {
		c.jsonSuccessArr()
	} else {
		c.jsonErrorArr()
	}
}

其中，`c.getDeveloper` 方法和 `c.getAuthCallbackUri` 方法需要根据具体情况进行实现。`c.jsonSuccessArr` 和 `c.jsonErrorArr` 方法可以在控制器中自定义实现，用于返回成功或者失败的结果。
