多部分/表单数据到数组中不处理 - multipart/form-data into array not processing

multipart/form-data into array not processing

基本上，我有这个表单数据，我试图使用 cURL 传递，这里它被硬编码到边界中并发送请求。

$postfields = '--Boundary+0xAbCdEfGbOuNdArY'."'r'n";
$postfields .= 'Content-Disposition: form-data; name="device_timestamp"'."'r'n'r'n";
$postfields .= (time() - (100 * rand(1,6)))."'r'n";
$postfields .= '--Boundary+0xAbCdEfGbOuNdArY'."'r'n";
$postfields .= 'Content-Disposition: form-data; name="photo"; filename="photo"'."'r'n";
$postfields .= 'Content-Type: image/jpeg'."'r'n'r'n";
$postfields .= file_get_contents($path)."'r'n";
$postfields .= '--Boundary+0xAbCdEfGbOuNdArY--'."'r'n";
$result = $this->curl_request('api.com/upload/',$postfields,array(
    CURLOPT_HTTPHEADER => array(
         'Content-type: multipart/form-data; boundary=Boundary+0xAbCdEfGbOuNdArY',
         'Content-Length: '.strlen($postfields),
         'Expect:'
    )
));

如何将这些数据传递到这样的函数中？

private function multipart_build_query($fields){
    $retval = '';
    foreach($fields as $key => $value){
        $retval .= "--".$this->boundary."'r'nContent-Disposition: form-data; name='"$key'"'r'n'r'n$value'r'n";
    }
    $retval .= "--".$this->boundary."--";
    return $retval;
}

我有点

猜测由于以下行，我必须修改我的multipart_build_query： Content-Type: image/jpeg

我尝试执行以下操作

$data_array = array(
    "device_timestamp" => (time() - (100 * rand(1,6))),
    "photo" => "@".$path,
);
$body = $curl->multipart_build_query($data_array);

还无济于事

我建议你做一个这样的数组：

$time  = (string) (time() - (100 * rand(1,6)));
$photo = file_get_contents($path);
$fields = array(
    array(
        'headers' => array(
            'Content-Disposition' => 'form-data; name="device_timestamp"',
            'Content-Length'      => strlen($time)
        ),
        'body' => $time
    ),
    array(
        'headers' => array(
            'Content-Disposition' => 'form-data; name="photo"; filename="photo"',
            'Content-Type'        => 'image/jpeg',
            'Content-Length'      => strlen($photo)
        ),
        'body' => $photo
    )
);

然后，该方法可以如下所示：

private function multipart_build_query($fields)
{
    $data = '';
    foreach ($fields as $field) {
        // add boundary
        $data .= '--' . $this->boundary . "'r'n";
        // add headers
        foreach ($field['headers'] as $header => $value) {
            $data .= $header . ': ' . $value . "'r'n";
        }
        // add blank line
        $data .= "'r'n";
        // add body
        $data .= $field['body'] . "'r'n";
    }
    // add closing boundary if there where fields
    if ($data) {
        $data .= $data .= '--' . $this->boundary . "--'r'n";
    }
    return $data;
}

您现在有一个非常通用的方法，它支持任何类型的字段。
