如何在React Native fetch中使用Authorization Header来使用Yelp API发出get请求

Question

我正在尝试在react-native中使用FETCH发布帖子请求。我收到验证错误。我在这里缺少什么？

if(!isset($errMSG))
    {


        $stmt = $user_home->runQuery("INSERT INTO cam_info (userID,
                                                            cam_name,
                                                cam_model,
                                            pixels,
                                    photoshoot,
                                    cam_rent,
                                    cam_img,
                                    mobile,
                                    state,
                                    address,
                                    upd_date,
                                    code )
                                                            VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) ");

        $stmt->bindParam(1,$id);
        $stmt->bindParam(2,$cam_name);
        $stmt->bindParam(3,$modelname);
        $stmt->bindParam(4,$pixel);
        $stmt->bindParam(5,$photoshoot);
        $stmt->bindParam(6,$rentpday);
        $stmt->bindParam(7,$userpic);
        $stmt->bindParam(8,$usermob);
        $stmt->bindParam(9,$state);
        $stmt->bindParam(10,$useraddrs);
        $stmt->bindParam(11,$upd_date);
        $stmt->bindParam(12,$ucode);

        if($stmt->execute())
        {

            $successMSG = "Record saved success";
        }
        else
        {
            $errMSG = "error while inserting....";
        }

谢谢。

getAccessToken() {

    let formData  = new FormData();
    formData.append('grant_type', 'client_credentials')
    formData.append('client_id', 'yourID')
    formData.append('client_secret', 'yourSecret')
    let headers = new Headers();

    return fetch('https://yourBaseUrl/oauth2/token/', {
        method: 'POST',
        headers: headers,
        body: formData,
    })
    .then((response) => response.json())      
}
