CURLOPT_WRITEDATA 传递指针给libcurl,该指针表明CURLOPT_HEADERFUNCTION 函数的stream指针的来源。 CURLOPT_READFUNCTION CURLOPT_READDATA libCurl需要读取数据传递给远程主机时将调用CURLOPT_READFUNCTION指定的函数,函数原型是:size_t function(void *ptr, size_t size, size_t nmemb,void *stream). CURLOPT_READDA...

1)CURLOPT_HEADERFUNCTION设置接收到http头的回调函数,原型为: size_t function(void *ptr,size_t size,size_t nmemb, void *stream); libcurl一旦接收到http 头部数据后将调用该函数。 2)CURLOPT_HEADERDATA传递指针给libcurl,该指针表明CURLOPT_HEADERFUNCTION函数的stream指针的来源。

()函数实现对特定页面发起请求的功能,其中curl_slist_append()用于增加新的请求头数据,在调用curl_easy_setopt()函数时,分别传入了CURLOPT_HTTPHEADER设置请求头,CURLOPT_WRITEFUNCTION设置回调,CURLINFO_PRIMARY_IP获取目标IP地址,CURLINFO_RESPONSE_CODE获取目标返回代码,此处的write_data()函数直接返回0则表示屏蔽...
