问题:
php的这段代码,不支持访问http时redirect到https,如:
访问:http://jtgl.beijing.gov.cn/jgj/lszt/659722/660341/index.html
307 Temporary Redirect导到:https://jtgl.beijing.gov.cn/jgj/lszt/659722/660341/index.html
请将该函数修改成能自动导到https并获取到相应body内容:
//发起https的get请求
function https_get($url,$timeout=120){
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_TIMEOUT,$timeout);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // 跳过检查
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); // 跳过检查
$res = curl_exec($curl);
curl_close($curl);
return $res; //返回json对象
}
回答:
要在PHP中自动将HTTP请求重定向到HTTPS并获取响应内容,您可以使用curl来检测HTTP响应头中的重定向,然后执行相应的HTTPS请求。以下是修改后的函数示例:
function https_get($url, $timeout = 120) {
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_TIMEOUT, $timeout);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true); // 启用重定向跟随
$response = curl_exec($curl);
$httpCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);
if ($httpCode == 301 || $httpCode == 302) {
$matches = array();
preg_match('/Location:(.*?)\n/', $response, $matches);
$newUrl = trim(array_pop($matches));
if (!empty($newUrl)) {
curl_setopt($curl, CURLOPT_URL, $newUrl);
$response = curl_exec($curl);
}
}
curl_close($curl);
return $response;
}
$url = "http://jtgl.beijing.gov.cn/jgj/lszt/659722/660341/index.html";
$response = https_get($url);
echo $response;
php -a 测试是OK的。
问题二:那直接在shell下用curl命令实现上面307的Location转向获取到转向后的内容,用什么参数实现呢?我记得好像是有相应参数的。
是的,您可以使用`curl`命令行工具来获取重定向后的内容。要实现HTTP 307重定向的自动跟随,您可以使用`-L`或`--location`参数,这会让`curl`自动跟随重定向并获取最终的内容。下面是示例:
使用`-L`参数,`curl`将自动处理HTTP 307 Temporary Redirect,并获取最终的内容。
3XX response code
-L, --location
(HTTP) If the server reports that the requested page has moved to a different location (indicated with a Location: header and a 3XX response code), this option will make
curl redo the request on the new place. If used together with -i, --include or -I, --head, headers from all requested pages will be shown. When authentication is used, curl
only sends its credentials to the initial host. If a redirect takes curl to a different host, it will not be able to intercept the user+password. See also --location-
trusted on how to change this. You can limit the amount of redirects to follow by using the --max-redirs option.
