Question

我必须将一个文件发布到服务器旁边，并附带几个post params。我从此服务器管理员收到的文档显示了帖子请求应该是什么样子的示例（ * 注意POST的自定义内容类型“multipart / x-api-remote-integration”）：

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--

以下是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内容，似乎正在正确接收帖子字段。但是它是未收到的文件。我不确定我做错了什么。任何意见都非常感谢。

我知道服务器正在读取用户名和pw数据，因为我已经测试了错误信息并收到了凭据错误。

当您告诉cURL上传文件时，Content-Type标题会自动设置为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);

这有用吗？
