我必须将文件连同一些帖子参数一起发布到服务器。我从该服务器管理员收到的文档显示了发布请求应该是什么样子的示例（*注意 POST “multipart/x-api-remote-integration”的自定义内容类型）：

POST /gateway/remote_send HTTP/1.0

Content-Type: multipart/x-api-remote-integration; boundary=ABC1234

Content-Length: 323

--ABC1234

Content-Type: application/x-www-form-urlencoded

profile_name=username&profile_pw=password1234&attached_type=action_1

--ABC1234

Content-Type: text/csv

Content-Disposition: attachment; filename="attachment.csv"
row1
row2
row3

--ABC1234--

下面是php代码：

<?php
function post(){
    $base_api_url = "https://hostserver.com/gateway/remote_send";

    $filename = realpath("/home/username/tests/test1234qwerty.csv");

    $payload['profile_name'] = "username";
    $payload['profile_pw'] = 'password1234';
    $payload['attached_type'] = 'action_1';
    $payload['filename'] = "@" . $filename . ";type=text/csv;";

    $curl_options = array(
        CURLOPT_URL => $base_api_url,
        CURLOPT_POST => true,
        CURLOPT_POSTFIELDS => http_build_query( $payload ),
        CURLOPT_HTTP_VERSION  => 1.0,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_VERBOSE => true,
        CURLOPT_HEADER => false,
    );

    $curl = curl_init();
    curl_setopt_array( $curl, $curl_options );
    $result = curl_exec( $curl );
    curl_close ($curl);
    echo $result;
  }

post();

从我从服务器收到的信息来看，似乎帖子字段已正确接收。但是，它是未收到的文件。我不确定我做错了什么。非常感谢任何输入。

我知道服务器读取的用户名和密码数据是正确的，因为我用错误的信息进行了测试并收到了凭据错误。

当您告诉 cURL 上传文件时，Content-Type标头会自动设置为multipart/form-data. 对于文档中的请求，您必须手动上传文件。

<?php
$url     = 'https://hostserver.com/gateway/remote_send';
$payload = array(
    'profile_name'  => 'username',
    'profile_pw'    => 'password1234',
    'attached_type' => 'action_1'
);
$file = realpath('/home/username/tests/test1234qwerty.csv');

// build multipart
$payload = http_build_query($payload);
$params  = "--ABC1234\r\n"
    . "Content-Type: application/x-www-form-urlencoded\r\n"
    . "\r\n"
    . $payload . "\r\n"
    . "--ABC1234\r\n"
    . "Content-Type: text/csv\r\n"
    . "Content-Disposition: attachment; filename=\"attachment.csv\"\r\n"
    . "\r\n"
    . file_get_contents($file) . "\r\n"
    . "--ABC1234--";

$first_newline      = strpos($params, "\r\n");
$multipart_boundary = substr($params, 2, $first_newline - 2);
$request_headers    = array();
$request_headers[]  = 'Content-Length: ' . strlen($params);
$request_headers[]  = 'Content-Type: multipart/x-api-remote-integration; boundary='
    . $multipart_boundary;

// send the request now

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);
curl_setopt($ch, CURLOPT_HTTPHEADER, $request_headers);

$reply = curl_exec($ch);

那样有用吗？
