将 PHP Curl 查询转换为 Python 请求

Question

我在尝试将以下 PHP curl 查询转换为 Python 请求时遇到了一些问题。

给定 PHP 代码

$cfile = new CURLFile($filePath,$fileType,$filename);
$request='{"signers":["abc@xyz.com"],"expire_in_days":10, "display_on_page":"all"}';
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array('authorization: Basic Base64encode(client_id:client_secret)'));
$post = array('file'=>$cfile,'request' =>$request);
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$res = curl_exec($ch)

我的 Python 代码版本

request_data = {}
request_data['signers'] = ['abc@xyz.com']
request_data['expire_in_days'] = 10
request_data['display_on_page'] = 'all'
temp_file_path = 'PdfTest.pdf'
files = {'file': open(temp_file_path, 'rb')}
headers = {}
headers['content-type'] = "multipart/form-data"
headers['authorization'] = 'Basic '+auth # auth contains b64 client:secret
r = requests.post(url, files=files, data={'request': request_data}, headers=headers)

考虑到我的请求 URL 和授权的 base 64 值相同。 PHP 代码从服务器返回正确的响应，但奇怪的是 Python 提供了一个响应告诉 "code":"UNSUPPORTED_MEDIA_TYPE"

Answer 1

经过更多检查，我似乎发现问题出在以下几行，files 需要强制 filetype 可以从 MimeTypes().guess_type(path)[0] 获得，request_data 应该是 json.dumps(request_data)

files = {'file': (temp_file_path, open(temp_file_path, 'rb'), filetype)}
# .... Other code
r = requests.post(url, files=files, data={'request': json.dumps(request_data)}, headers=headers)

    $url_0 = 'https://pranatrader.ir/services/LoginUser';
    $post_filed = 'username=0061625671&password=db00d9250ef8a9243e6d9bc1e960f09d1aaf517a&preferredClientID=Mobile&ip=undefined';

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, "$url_0");

    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1');
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_filed);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'cache-control: no-cache',
        'Content-Type: application/x-www-form-urlencoded',
        'Content-Length: 107',
        'Host: pranatrader.ir',
        'Connection: Keep-Alive',
        'User-Agent: okhttp/3.12.1'
    ));

    $server_output = curl_exec($ch);

    #echo '<xmp>' . print_r($server_output, true) . '</xmp>';

    $header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
    $header = substr($server_output, 0, $header_size);
    $body = substr($server_output, $header_size);


    $json_result = json_decode($body);

    echo '<xmp>' . print_r($json_result, true) . '</xmp>';

    curl_close($ch);
