如何擷取微信開放平台的預授權碼？

怎樣擷取開放平台的預授權碼？是通過填寫的哪個url進入擷取的？

報錯：

array(2) { ["errcode"]=> int(41002) ["errmsg"]=> string(13) "appid missing" } 

代碼部分：

    $ch = curl_init();    $url="https://api.weixin.qq.com/cgi-bin/component/api_component_token";    $data=array(        'component_appid'=>$APPID,        'component_appsecret'=>$SECRET,        'component_verify_ticket'=>$ticket['ticket']    );    $data=http_build_query($data);    //var_dump($data);    $ch = curl_init();//開啟    curl_setopt($ch, CURLOPT_POST, true);    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);    curl_setopt($ch, CURLOPT_URL, $url);    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);    $response  = curl_exec($ch);    curl_close($ch);//關閉    $result = json_decode($response,true);

appid missing
你沒有定義$APPID變數

是$data傳值的問題，已經解決了

遇到同樣問題，傳參的時候是json格式 之前直接post 3個參數一直{"errcode":41002,"errmsg":"appid missing"} 這個錯誤。json_encode(['component_appid'=>,'component_appsecret'=>,'component_verify_ticket'=>]);

$data 要以JSON格式提交
