php的curl请求带formdata,带有ContentDisposition的PHPcURL：formdata

我将这个Instagram cURL转换成PHP看起来很迷惑&＃xff0c;如下所示&＃xff1a;

curl -F &＃39;client_id&＃61;CLIENT_ID&＃39; \

-F &＃39;client_secret&＃61;CLIENT_SECRET&＃39; \

-F &＃39;grant_type&＃61;authorization_code&＃39; \

-F &＃39;redirect_uri&＃61;AUTHORIZATION_REDIRECT_URI&＃39; \

-F &＃39;code&＃61;CODE&＃39; \

https://api.instagram.com/oauth/access_token这是我当前的代码&＃xff0c;有一个错误

{

"error_type": "OAuthException",

"code": 400,

"error_message": "You must provide a client_id"

}带样本值的当前代码&＃xff1a;

$client_id &＃61; "7d60c47cdwe249069cdb07a0f28e19cb";

$client_secret &＃61; "de5awwe3ebf1443d8dcf0fbc88e5ab1b";

$ch &＃61; curl_init();

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

//format URL to grant access to email and sitename passed

$data &＃61; &＃39;{"client_id":"&＃39;.$client_id.&＃39;","client_secret":"&＃39;.$client_secret.&＃39;","grant_type":"&＃39;.$grant_type.&＃39;","redirect_uri":"&＃39;.$redirect_uri.&＃39;","code":"&＃39;.$code.&＃39;"}&＃39;;

curl_setopt($ch, CURLOPT_URL, &＃39;https://api.instagram.com/oauth/access_token&＃39;);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_HTTPHEADER, array(&＃39;Content-Type: application/json&＃39;));

curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");

//execute cURL call and get template data

$output &＃61; curl_exec($ch);

curl_close($ch);

echo $output;
