在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,我在互联网上找到了该脚本,但无法正常工作。

<?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);
?>

我在做什么错了?

谢谢。

编辑:经过大量测试,如果我回显$ data变量,则会收到此消息:

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

更新 我将在此处发布完整的工作代码。

<?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);
?>

初始部分取自此continue processing php after sending http response。这是将立即答复发送回Slack并避免出现“达到超时”消息的必要条件。

答案 0 :(得分:1)

缺少范围

您的令牌缺少必要的范围,这里为files:write:user

要添加其他范围:

假设您有一个Slack应用程序,请转到该应用程序的管理页面,然后将其添加到“ Ouath”子页面上,这里有一个作用域部分,您可以在其中添加它。这是您的应用程序的直接链接:https://api.slack.com/apps

此后,您需要将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显然仅适用于文件的绝对路径。 (see this answer)。快速修复将是这样的:

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