上传文件以减少文件的数量。用PHP上传

2022-06-14 00:00:00 slack-api slack php

我正在尝试使用files.Upload方法将文件上载到Slack,但到目前为止只收到了一条空消息。

这就是代码,我在Internet上找到了此脚本,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:在多次测试后,如果我回显$DATA变量,则收到此消息:

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

更新 我将在此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continue processing php after sending http response。这是向Slack发送即时回复并避免出现"已达到超时"消息所必需的。


解决方案

缺少作用域

您的令牌缺少必要的作用域,此处:files:write:user

添加其他作用域:

假设你有一个Slack应用程序,转到你的应用程序的管理页面,然后在"Ouath"子页面上添加它,在那里有一个范围部分,你可以在那里添加它。以下是指向您的应用程序的直接链接:https://api.slack.com/apps。

之后,您需要将应用程序重新安装到工作区,以使更改生效。

使用CurlFile

另一个潜在的缺陷是CurlFile显然只适用于文件的绝对路径。(see this answer)。一个简单的解决办法是:

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