我正在学习 Docker 和 Swoole。运行一个包含 2 个文件和一个空目录的 Docker 容器。在浏览器中访问 HTTP 服务器时，不显示图像（获取损坏的图像图标）。我已经从外部网页尝试了 PNG，该图像显示正确。我也试过“docker run -it hello-swoole sh”并确认容器显示data index.php image.png文件FROM php:7.2-fpmRUN apt-get update && apt-get install vim -y && \ apt-get install openssl -y && \ apt-get install libssl-dev -y && \ apt-get install wget -y RUN cd /tmp && wget https://pecl.php.net/get/swoole-4.2.9.tgz && \ tar zxvf swoole-4.2.9.tgz && \ cd swoole-4.2.9 && \ phpize && \ ./configure --enable-openssl && \ make && make installRUN touch /usr/local/etc/php/conf.d/swoole.ini && \ echo 'extension=swoole.so' > /usr/local/etc/php/conf.d/swoole.iniRUN mkdir -p /app/dataWORKDIR /appCOPY ./app /appEXPOSE 8101CMD ["/usr/local/bin/php", "/app/index.php"]索引.php<?php$http = new swoole_http_server("0.0.0.0", 8101);$http->on("start", function ($server) { echo "Swoole http server is started at http://127.0.0.1:8101\n";});$http->on("request", function ($request, $response) { $response->header("Content-Type", "text/html; charset=utf-8"); $response->end('<!DOCTYPE html><html><body><img src="image.png"></body></html>');});$http->start();知道为什么不显示 image.png 吗？更新 以下工作来显示图像，但没有显示任何 HTML。感觉爱德华的答案在这里是正确的，我还没有正确处理所有请求。现在可以肯定，这个问题更像是一个 Swoole 问题而不是 Docker 问题。<?php$http = new swoole_http_server("0.0.0.0", 8101);$http->on("start", function ($server) { echo "Swoole http server is started at http://127.0.0.1:8101\n";});$http->on("request", function ($request, $response) { $response->header('Content-Type', 'image/png'); $response->sendfile('image.png'); // code seems to stop executing here $response->header("Content-Type", "text/html; charset=utf-8"); $response->end('<!DOCTYPE html><html><body><img src="/image.png"></body></html>');});$http->start();

我设法在这里找到答案：https : //www.swoole.co.uk/docs/modules/swoole-http-server/configuration ...
只需要添加：
$http->set([
'document_root' => '/app',
'enable_static_handler' => true,
]);
完整更新代码
<?php
$http = new swoole_http_server("0.0.0.0", 8101);
$http->set([
'document_root' => '/app',
'enable_static_handler' => true,
]);
$http->on("start", function ($server) {
echo "Swoole http server is started at http://127.0.0.1:8101\n";
});
$http->on("request", function ($request, $response) {
$response->header("Content-Type", "text/html; charset=utf-8");
$response->end('<!DOCTYPE html><html><body><img src="image.png" height="200"></body></html>');
});
$http->start();
