如何在vc ++中编写简单的请求响应程序 [英] how to write simple request response program in vc++
问题描述
您好我想在vc ++中制作简单的请求响应程序。这就像我在helloworld.jsp上的localhost那样输出hello world当我向hellowworld.jsp发送请求它应该给我输出hello world。我尝试了几件事，但它也有效，但它给了我helloworld.jsp整个网页的输出
Hi i want to make simple request response program in vc++. which is like on my localhost at helloworld.jsp there is output hello world when i send request to hellowworld.jsp it should give me output hello world. i try couple of things but it is also working but it gives me output of whole webpage of helloworld.jsp
#include "stdafx.h"
#include <stdio.h>
#include "curl/curl.h"
int main(void)
{
CURL *curl;
CURLcode res;
/* In windows, this will init the winsock stuff */
curl_global_init(CURL_GLOBAL_ALL);
/* get a curl handle */
curl = curl_easy_init();
if(curl) {
/* First set the URL that is about to receive our POST. This URL can
just as well be a https:// URL if that is what should receive the
data. */
curl_easy_setopt(curl, CURLOPT_URL, "http://localhost:8080/asigra_1/helloword.jsp");
/* Now specify the POST data */
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "name=daniel&project=curl");
/* Perform the request, res will get the return code */
res = curl_easy_perform(curl);
/* Check for errors */
if(res != CURLE_OK)
fprintf(stderr, "curl_easy_perform() failed: %s\n",
curl_easy_strerror(res));
/* always cleanup */
curl_easy_cleanup(curl);
}
curl_global_cleanup();
system("pause");
return 0;
}
i得到以下输出
i get following output for it
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.or
g/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
hello word
</body>
</html>Press any key to continue . . .
我应该如何才能获得输出在一行中就像hello world。
how should i get output only in one line which is like hello world.
推荐答案
最好的解决方案是在客户端使用HTML解析器，以便过滤掉消息。如果它很复杂，您只需使用HTML中未使用的标记包装您的消息即可。检查以下示例，
The best solution is use an HTML parser in client side so you can filter out the message. If it is complex you can simply wrap your message with a tag which is not used in HTML. Check the following example,
<body>
<message>hello word</message>
现在您可以找到内的内容;消息>< / message> 在c ++中使用字符串操作技术的标记。如果您愿意，也可以使用正则表达式。
now you can find for the content within the <message></message> tags with string manipulation techniques in c++. If you like you can use regular expressions too.
