我正在尝试使用chat API、在whatsApp聊天中发送图像
通过引用：https://blog.chat-api.com/manuals_and_tutorials/api_whatsapp_send_file_php/
在这种情况下，代码如下：
$data = json_encode(array(
'chatId'=>$phone.'@c.us',
'body'=>'URL of the image',
'filename'=>'picture.jpg',
'caption'=>'Hey! There is a file!'
));
我从html表单发送chartId,filename and caption，我的html表单如下：
<?php
if(isset($_POST['submit'])){
$apiURL = 'api.chat-api.com/instanceXXXXX/';
$token = 'abcdefgABCDEFG';
$phone = $_POST['phone_no'];
$file_name = $_POST['file_name'];
$caption = $_POST['caption'];
$data = json_encode(array(
'chatId'=>$phone.'@c.us',
'body'=>'URL of the image', //how can i make my local image to this URL
'filename'=>$file_name,
'caption'=> $caption
));
$url = $apiURL.'sendFile?token='.$token;
$options = stream_context_create(['http' => [
'method' => 'POST',
'header' => 'Content-type: application/json',
'content' => $data
]
]);
$response = file_get_contents($url,false,$options);
echo $response; exit;
}
?>
<html>
<body>
<form action = '' method = ''>
<input type = "text" name = "phone_no" id = "phone_no" />
<img src = "#" name = "img" id = "img" /> // here local(from my desktop) image is i am displaying
<input type = "text" name = "file_name" id = "file_name" />
<input type = "text" name = "caption" id = "caption" />
<input type = "submit" name = "submit" value = "Send" />
</form>
</body>
</html>
这里我的问题是如何将我的本地图像发送到聊天中，我们是否将本地图像转换为URL。我不理解在这件事上帮我。
非常感谢。注意$data中的URL如下：图像的地址(https://test.com/PHP/picture.jpg)
请转换为基数64，
$photoPath = 'folder/path.jpg';
$getExtension = explode(".",$photoPath);
$base64 = 'data:image/'.$getExtension[1].';base64,'.file_get_contents($photoPath);
$data = json_encode(array(
'chatId'=>$phone.'@c.us',
'body'=> $base64, //how can i make my local image to this URL
'filename'=>$file_name,
'caption'=> $caption
));
