在 PHP 中使用 files.upload 将文件上传到 slack

Upload a file to slack with files.upload in PHP

我正在尝试使用 files.upload 方法将文件上传到 Slack,但到目前为止我只收到一条空白消息。

这是代码,我在网上找到了这个脚本,但它不起作用。

<?php
include '../connessione.php';

$slacktoken = "myToken"; //this is not the real token ofc
$header = array();
$header[] = 'Content-Type: multipart/form-data';
$file = new CurlFile('../tmp/slack_icon.png', 'image/png');

$postitems =  array(
    'token' => $slacktoken,
    'channels' => "test_channel",
    'file' =>  $file,
    'text' => "This is my photo",
    'title' => "Photo title",
    'filename' => "myIcon.jpg"
);

$curl = curl_init();
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
curl_setopt($curl, CURLOPT_URL, "https://slack.com/api/files.upload");
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS,$postitems);

//Execute curl and store in variable
$data = curl_exec($curl);
?>

我做错了什么?

谢谢。

编辑:经过大量测试后,如果我回显 $data 变量,我会收到此消息:

{"ok":false,"error":"missing_scope","needed":"files:write:user","provided":"identify,commands"}

更新 我将在此处 post 提供完整的工作代码。

<?php
include '../connessione.php';

    // Buffer all upcoming output...
    ob_start();

    // Send your response.
    echo "Here be response";

    // Get the size of the output.
    $size = ob_get_length();

    // Disable compression (in case content length is compressed).
    header("Content-Encoding: none");

    // Set the content length of the response.
    header("Content-Length: {$size}");

    // Close the connection.
    header("Connection: close");

    // Flush all output.
    ob_end_flush();
    ob_flush();
    flush();

    // Close current session (if it exists).
    if(session_id()) session_write_close();


$channel = $_POST['channel_id'];
$slacktoken = "myToken";
$header = array();
$header[] = 'Content-Type: multipart/form-data';
$file = new CurlFile('slack_icon.png', 'image/png');



$postitems =  array(
        'token' => $slacktoken,
        'channels' => "test_channel",
        'file' =>  $file,
        'text' => "This is my photo",
        'title' => "Photo title",
        'filename' => "myIcon.jpg"
    );

$curl = curl_init();
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
curl_setopt($curl, CURLOPT_URL, "https://slack.com/api/files.upload");
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $postitems);

//Execute curl and store in variable
$data = curl_exec($curl);
?>

开头部分取自此。这需要立即回复 Slack 并避免 "Timeout was reached" 消息。

缺少范围

您的令牌缺少必要的范围,此处:files:write:user

要添加其他范围:

假设您有一个 Slack 应用程序,转到您的应用程序的管理页面,然后将其添加到 "Ouath" 子页面上,您可以在其中添加一个范围部分。这是直接 link 到您的应用程序:https://api.slack.com/apps

之后您需要将您的应用程序重新安装到工作区,以便更改生效。

使用 CurlFile

另一个潜在的陷阱是 CurlFile 显然只适用于文件的绝对路径。 (see this answer)。快速修复是这样的:

$file = new CurlFile(realpath(dirname(__FILE__) . '/../tmp/slack_icon.png'), 'image/png');
