PHP curl CURLOPT_RESOLVE 不工作

Question

我在两台不同的服务器上有 example.com，我使用 php curl 连接到一台服务器，执行一些任务，然后尝试连接到另一台服务器并执行其他一些任务，但它第二次不遵守 CURLOPT_RESOLVE正如您在详细输出中看到的那样。

我尝试将 CURLOPT_DNS_CACHE_TIMEOUT 设置为 0，但仍然连接到旧 IP。

知道我该如何解决吗？

不幸的是，我无法直接连接到 ip。

* Added example.com:80:207.230.220.255 to DNS cache
* Hostname was found in DNS cache
*   Trying 207.97.92.288...
* Connected to example.com (207.97.92.288) port 80 (#0)
> GET /example.php HTTP/1.1

Host: example.com

Accept: */*

添加代码:

$check_ping_resolve = ["example.com:80:207.230.220.255"];

$check_ping = "http://example.com/123.php";

$check_ping_verbose = fopen(dirname(__FILE__) . '/ping.txt', 'w');

$check_ping_curl = curl_init();
curl_setopt($check_ping_curl, CURLOPT_SSL_VERIFYHOST,0);
curl_setopt($check_ping_curl, CURLOPT_SSL_VERIFYPEER,0);
curl_setopt($check_ping_curl, CURLOPT_RETURNTRANSFER,1);
curl_setopt($check_ping_curl, CURLOPT_DNS_CACHE_TIMEOUT, 0);
curl_setopt($check_ping_curl, CURLOPT_RESOLVE, $check_ping_resolve);
curl_setopt($check_ping_curl, CURLOPT_URL, $check_ping);
curl_setopt($check_ping_curl, CURLOPT_VERBOSE, 1);
curl_setopt($check_ping_curl, CURLOPT_STDERR, $check_ping_verbose);

$check_ping_curl_result = curl_exec($check_ping_curl);

我有同样的问题，我通过添加这个选项解决了它:

curl_setopt($ch, CURLOPT_DNS_USE_GLOBAL_CACHE, false);
