电报Api错误503服务不可用

Question

我在主机上有一个电报机器人。

一天后...机器人无法正常工作。

getwebhookinfo是说：

has_custom_certificate:false

pending_update_count:1

last_error_date:1504179338

last_error_message:Wrong response from the webhook: 503 Service Unavailable

max_connections:40

我也使用PHP测试ping api.telegram.org，

<?php
$wait = 1; // wait Timeout In Seconds
$host = 'api.telegram.org';
$ports = [
    'http'  => 80,
    'https' => 443,
    'ftp'   => 21,
];
foreach ($ports as $key => $port) {
    $fp = @fsockopen($host, $port, $errCode, $errStr, $wait);
    echo "Ping $host:$port ($key) ==> ";
    if ($fp) {
        echo 'SUCCESS';
        fclose($fp);
    } else {
        echo "ERROR: $errCode - $errStr";
    }
    echo PHP_EOL;
}

Ping api.telegram.org:80 (http) ==> SUCCESS Ping api.telegram.org:443 (https) ==> SUCCESS Ping api.telegram.org:21 (ftp) ==> ERROR: 110 - Connection timed out

如何解决呢？

新更新

添加添加print_r调试curl到我的机器人代码：

$curl = curl_init('https://api.telegram.org/bot'.$token.'/sendMessage');
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_HEADER, 1);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($param));
$response = curl_exec($curl);
$code = curl_getinfo($curl);
curl_close($curl);
print "\n=========\n".$response."\n\n";======>for debug
print_r($code);======>for debug
print "\n\n";======>for debug

接下来，我在笔记本电脑（os：gnu / linux）上运行此命令。

$ curl --tlsv1 -v -k -X POST -H "Content-Type: application/json" -H "Cache-Control: no-cache"  -d '{
> "update_id":10000,
> "message":{
>   "date":1441645532,
>   "chat":{
>      "last_name":"Test Lastname",
>      "id":381078330,
>      "first_name":"Test",
>      "username":"Test"
>   },
>   "message_id":1365,
>   "from":{
>      "last_name":"Test Lastname",
>      "id":381078330,
>      "first_name":"Test",
>      "username":"Test"
>   },
>   "text":"/start"
> }
> }' "********"

同样在运行此命令后，我从我的机器人收到消息！

如何解决？

您可以通过将类似的数据发布到服务器来发现问题， 这里有一些数据可以在curl -d JSON ，只需将其复制并在自己的服务器上运行即可。

顺便说一句，检查您的CDN配置（如果您已在该服务器上应用），暂时禁用泛洪或进行任何检查。
