php - 如何使用 php curl 7.68 修复缺少的 Content-Length？

Question

背景：我是一名 Roku 开发人员，使用 PHP 来打包我的应用程序。在我从 Ubuntu 18.04 升级到 20.04 之前，我的 PHP 代码一直运行良好。一旦 curl 升级到 7.68，我的脚本就坏了。当我使用 curl 来访问硬件设备时，我没有更改服务器代码的选项。

问题：使用 PHP curl 时，由于没有 Content-Length，我现在收到 HTTP 411 错误。但是当我使用 curl 命令行时，它工作正常。如何为 curl 7.68 解决此问题？

实际PHP代码：

function remove() {
    global $E;
    pl("Removing dev app from host $E[ROKU_DEV]");
    home();
    $data = [
        'mysubmit'=>'Delete',
        'archive'=>"",
        'passwd'=>""
    ];
    $response = curl_post("http://$E[ROKU_DEV]/plugin_install", $data, $E['USERPASS']);
    $output = filterString($response, "Roku.Message", "trigger('Set message content', '", "').trigger('Render', node);");
    finish("Remove: $output");
}

function curl_post($url, $data = '', $digest = '') {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_VERBOSE, true);
    curl_setopt($ch, CURLOPT_POST, true);
    if(!empty($digest)) {
        curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
        curl_setopt($ch, CURLOPT_USERPWD, $digest);
    }
    $result = curl_exec($ch);
    $info = curl_getinfo($ch);
    $errno = curl_errno($ch);
    if($errno) {
        $result = sprintf("cURL Error (%d): %s\n", $errno, curl_strerror($errno));
    } else if($info['http_code'] >= 300) {
        $result = sprintf("HTTP Error (%d): %s\n", $info['http_code'], httpStatusString($info['http_code']));
    }
    curl_close($ch);
    return $result;
}

这将返回：

这是我的 curl 命令行：

curl --digest -urokudev:$ROKU_PASS -v -X POST -F 'mysubmit=Delete' -F 'passwd=' -F 'archive=' http://$ROKU_DEV/plugin_install

这是结果：

Note: Unnecessary use of -X or --request, POST is already inferred.
