邮件员使用raw在API上传文件

How do you upload a file on postman using raw mode.

I used a json entry like this:

{
    "inp_doc_uid": "750761691595cf3398da311004881705",
    "tas_uid": "71415152859433e07c33b11085554015",
    "app_doc_comment":"test upload",
    "form":"@/User/images.jpg"
}

the problem was the @ in php was deprecated and now recommended to use curlFile, how to do it in a json form?

Thanks.

Since you are sending the image as part of the JSON, you would need to encode it. Base64 encoding is a good choice. On the server side, you will need to decode it as well.

See this answer to How to convert an image to base64 encoding?:

$imagedata = file_get_contents("/path/to/image.jpg");
$base64 = base64_encode($imagedata);

Once you have the data, you can add it to the JSON:

{
    "inp_doc_uid": "750761691595cf3398da311004881705",
    "tas_uid": "71415152859433e07c33b11085554015",
    "app_doc_comment":"test upload",
    "form":"TWFuIGlzIGRpc3R..."
}
