带有文件附件的PHP Curl post；自定义内容类型标题

我必须将一个文件和几个post参数一起发布到服务器。我从这个服务器管理员那里收到的文档显示了post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）：

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();

告诉cURL上载文件时，
内容类型
标题将自动设置为
多部分/表单数据
。对于文档中的请求，您必须手动上载文件

尝试从根目录运行代码，并使用
$filename=realpath（“tests/test1234qwerty.csv”）看看这是否有帮助。我以前在文件夹名称前面使用
/
以及使用这种路径时遇到过类似的问题。感谢您的快速回复和建议。我刚刚试过，不幸的是，我仍然看到关于文件附件的相同响应。不客气。对不起，我怀疑我能帮上什么忙。祝你一切顺利，干杯谢谢你，先生！我对您感激不尽。@mishanon是的，两次–一次是主表单数据，另一次是附加的CSV文件。这两个内容类型标题都出现在POST数据中–主内容类型标题设置为
multipart/x-api-remote-integration
。
