API請求響應使用curl php發送0（零）

Question

我正在嘗試在multipart / form-data中發送圖像URL的請求，但是當我嘗試使用@進行轉換時，我得到0作為響應。 請幫我解決這個問題

$img='http://mai.com/images/DC/Avanti.png';
    $imagedata = array(
        "name"=>'@'.$img,
        "image_collection_id"=>$fid
    );
    $headers2= array('Accept: application/json','Content-Disposition: form-data','Referer: https://pro.avio.com/advert','Origin: https://pro.avio.com','Content-Type: multipart/form-data',"Authorization: Bearer " . $access_token,'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36'); 
    $ch2 = curl_init();
    curl_setopt($ch2, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch2, CURLOPT_URL, 'https://api-pro.avio.com/api/image');
    curl_setopt($ch2, CURLOPT_POST, true);
    curl_setopt($ch2, CURLOPT_HEADER, true);
    curl_setopt($ch2, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch2, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch2, CURLINFO_HEADER_OUT, true);//
    curl_setopt($ch2, CURLOPT_HTTPHEADER, $headers2);
    curl_setopt($ch2, CURLOPT_POSTFIELDS,$imagedata);
    $response2 = curl_exec($ch2);
    $err = curl_error($ch2);
    $resultStatus = curl_getinfo($ch2, CURLINFO_HTTP_CODE);
    curl_close($ch2);
    echo $resultStatus;

開發人員給出的示例請求是

"request": {
    "method": "POST",
    "url": "https://api-pro.avio.com/api/image",
    "httpVersion": "unknown",
    "headers": [
        {
            "name": "Accept",
            "value": "application/json"
        },
        {
            "name": "Referer",
            "value": "https://pro.avio.com/advert"
        },
        {
            "name": "Origin",
            "value": "https://pro.avio.com"
        },
        {

        },
        {
            "name": "Authorization",
            "value": "Bearer xxxxxx"
        },
        {
            "name": "Content-Type",
            "value": "multipart/form-data; boundary=----WebKitFormBoundaryq3A6Lz2bINdfNick"
        }
    ],

    "bodySize": 295,
    "postData": {
        "mimeType": "multipart/form-data; boundary=----WebKitFormBoundaryq3A6Lz2bINdfNick",
        "text": "------WebKitFormBoundaryq3A6Lz2bINdfNick\r\nContent-Disposition: form-data; name=\"name\"; filename=\"shippable.png\"\r\nContent-Type: image/png\r\n\r\n\r\n------WebKitFormBoundaryq3A6Lz2bINdfNick\r\nContent-Disposition: form-data; name=\"image_collection_id\"\r\n\r\n175\r\n------WebKitFormBoundaryq3A6Lz2bINdfNick--\r\n"
    }
}

嘗試使用CURLFile （ 在此處檢查）

不要在文件名前添加@符號，而應執行以下操作

$img='http://mai.com/images/DC/Avanti.png';
$imagedata = new CURLFile($img);

您將其余部分保持不變，並按以下方式調用POST字段：

curl_setopt($ch2, CURLOPT_POSTFIELDS, $imagedata);

您可以在此處找到有關@運算符的更多信息。 您應該專門檢查CURLOPT_SAFE_UPLOAD選項。
