【问题描述】：

我正在尝试使用Whatsapp Cloud API 发送图像。使用PHP，我可以成功发送普通短信。

浏览文档时，“MEDIA_OBJECT_ID”是什么意思？举个例子就好了。

curl -X  POST \
 'https://graph.facebook.com/v13.0/FROM_PHONE_NUMBER_ID/messages' \
 -H 'Authorization: Bearer ACCESS_TOKEN' \
 -d '{
  "messaging_product": "whatsapp",
  "recipient_type": "individual",
  "to": "PHONE_NUMBER",
  "type": "image",
  "image": {
    "id" : "MEDIA_OBJECT_ID"
  }
}'

谢谢

我猜您首先需要上传媒体文件，从响应中获取媒体对象 ID，然后在发布消息时使用该 ID？

标签： php whatsapp

【解决方案1】：

您需要将媒体上传到https://graph.facebook.com/v13.0/FROM_PHONE_NUMBER_ID/media

响应将为您提供“MEDIA_OBJECT_ID”

或

改用图片链接

curl -X  POST \
 'https://graph.facebook.com/v13.0/FROM_PHONE_NUMBER_ID/messages' \
 -H 'Authorization: Bearer ACCESS_TOKEN' \
 -d '{
  "messaging_product": "whatsapp",
  "recipient_type": "individual",
  "to": "PHONE_NUMBER",
  "type": "image",
  "image": {
    "link" : "Image URL"
  }
}'

我建议您从 Developer Dashboard 下载 WhatsApp Cloud API Postman 合集，以备日后疑虑：

转到https://developers.facebook.com/apps/
选择您的 WhatsApp 应用程序在左侧边栏中，转到 WhatsApp -> 入门点击“在 Postman 中运行”按钮以打开完整的 API 示例集合

顺便说一句，我建议您为 WhatsApp Cloud API 安装 PHP SDK：

compose require netflie/whatsapp-cloud-api

首先，您需要将媒体文件上传到 WhatsApp 服务器，然后 WhatsApp 会回复 MEDIA_OBJECT_ID

$target="/home/rishabh/uploads/myImage.png";
$mime=mime_content_type('myImage.png')
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/v13.0/FROM_PHONE_NUMBER_ID/media');

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, file_get_contents($target));
$headers = array();
$headers[] = "Authorization:Bearer $YOUR_WHATSAPP_ACCESS_TOKEN";
$headers[] = "Content-Type: $mime";
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = json_decode(curl_exec($ch), true);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

$MEDIA_OBJECT_ID = $result['media'][0]['id']; //MEDIA OBJECT ID

现在，您将获得媒体对象 ID。您需要从 API 发送媒体

$FileName="Caption Name or Image Name";
$messageBody = [
                "recipient_type" => "individual",
                "to" => "$to_number",
                "type" => "image",
                "image" => [
                    "id" => $MEDIA_OBJECT_ID, // MEDIA OBJECT ID
                    "caption" => $FileName,
                ]
            ];

$curl = curl_init();
    curl_setopt_array($curl, array(
        CURLOPT_URL => 'https://graph.facebook.com/v13.0/FROM_PHONE_NUMBER_ID/messages',
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_ENCODING => '',
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_TIMEOUT => 0,
        CURLOPT_FOLLOWLOCATION => true,
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => 'POST',
        CURLOPT_POSTFIELDS => json_encode($messageBody),
        CURLOPT_HTTPHEADER => array(
            "Authorization:Bearer $YOUR_WHATSAPP_ACCESS_TOKEN",
            'Content-Type: application/json'
        ),
    ));
    $response = json_decode(curl_exec($curl), true);
    $status_code = curl_getinfo($curl, CURLINFO_HTTP_CODE);
    curl_close($curl);

这是不同类型的媒体 JSON

 // for mp3
     $messageBody = [
                    "recipient_type" => "individual",
                    "to" => "$to_number",
                    "type" => "audio",
                    "audio" => [
                        "id" => $MEDIA_OBJECT_ID, // MEDIA OBJECT ID
                    ]
                ];
    
    // for pdf, doc, apk etc
      $messageBody = [
                    "recipient_type" => "individual",
                    "to" => "$to_number",
                    "type" => "document",
                    "document" => [
                        "id" => $MEDIA_OBJECT_ID, // MEDIA OBJECT ID,
                        "caption" => $fileName,
                        "filename" => $fileName,
                    ]
                ];
    
     // for mp4
     $messageBody = [
                    "recipient_type" => "individual",
                    "to" => "$to_number",
                    "type" => "video",
                    "video" => [
                       "id" => $MEDIA_OBJECT_ID, // MEDIA OBJECT ID,
                        "caption" => $media['fileName'],
                    ]
                ];
    
    $RequestJSON = json_encode($messageBody)

我试图点击上传媒体来获取媒体对象 ID，但我得到一个异常代码 1 和 500 系列的状态代码。

解决办法是什么？
