我有一个 wxWidgets 应用程序，我想为用户添加一种以简单(实现和使用)、可靠、跨平台和安全的方式提交反馈的方法。在 SSL 上使用 HTTP POST 似乎最符合这些要求(尽管我会考虑建议其他方法的答案)。然而，wxWidgets 对 HTTPS 的支持似乎有限。
以下是我考虑过的一些选项以及它们存在的问题:
最佳答案
我决定使用链接到 openssl 的 libCURL。这两个包都可以在大多数 Linux 系统上使用，并且可以相当容易地在 Windows 和 OS X 上构建。
这是发送反馈的示例 C 代码:
#include <stdio.h>
#include <string.h>
#include <curl/curl.h>
#include <curl/types.h>
#include <curl/easy.h>
int main(int argc, char *argv[])
{
CURL *curl;
CURLcode res;
struct curl_httppost *formpost=NULL;
struct curl_httppost *lastptr=NULL;
struct curl_slist *headerlist=NULL;
static const char buf[] = "Expect:";
curl_global_init(CURL_GLOBAL_ALL);
/* Fill in the name field */
curl_formadd(&formpost,
&lastptr,
CURLFORM_COPYNAME, "name",
CURLFORM_COPYCONTENTS, "John Doe",
CURLFORM_END);
/* Fill in the comments field */
curl_formadd(&formpost,
&lastptr,
CURLFORM_COPYNAME, "comments",
CURLFORM_COPYCONTENTS, "using HTTPS POST\nline 2\nline 3",
CURLFORM_END);
curl = curl_easy_init();
/* initalize custom header list (stating that Expect: 100-continue is not
wanted */
headerlist = curl_slist_append(headerlist, buf);
if(curl) {
/* what URL that receives this POST */
curl_easy_setopt(curl, CURLOPT_URL,
"https://some_host.com/path/feedback.php");
// Uncomment to disable certificate checks
//curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0);
//curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 0);
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headerlist);
curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost);
res = curl_easy_perform(curl);
printf("Curl result: %d\n", res);
/* always cleanup */
curl_easy_cleanup(curl);
/* then cleanup the formpost chain */
curl_formfree(formpost);
/* free slist */
curl_slist_free_all (headerlist);
}
return 0;
}
可以像这样在 Linux 上编译:
gcc post.c -lcurl -o post
这是接受该帖子的示例 PHP 代码:
<?php
$recipient = "john@some_host.com";
if (empty($_POST)) {
// We only accpet POSTs
header('HTTP/1.0 403 Forbidden');
exit;
} else {
// Handle a POST
$message .= "Submitted at ".date("F j, Y, g:i a")."\n\n";
$message .= "Name:\n";
$message .= $_POST['name']."\n\n";
$message .= "-------------------------------------------\n\n";
$message .= "Comments:\n\n";
$message .= $_POST['comments']."\n\n";
// Send message to email address
$sent = mail($recipient, "Feedback",
$message, "From: Feedback <noreply@some_host.com>\r\n");
if ($sent) {
?>
<html>
<body>
Got POST and sent email:
<pre><? echo $message; ?></pre>
</body>
</html>
<?php
} else {
// Return an error
header('HTTP/1.0 500 Internal Server Error', true, 500);
exit;
}
}
?>
