C语言怎么使用爬虫ip代码示例

数据抓取工作必不可少的就是需要海量爬虫ip支持，那么使用爬虫ip怎么配合C语言来运行项目？下列文档的代码可以供大家参考下。

#include

#include

#include

#include "curl/curl.h"

using namespace std;

static size_t WriteMemoryCallback(void* ptr, size_t size, size_t nmemb, void* stream) {

 size_t nsize = size * nmemb;

 string* strdata = (string*)stream;

 if (strdata)

   strdata->append((const char*)ptr, nsize);

 return nsize;

}

void Proxy(string& resp) {

   CURL* curl = curl_easy_init();

   CURLcode res;

   if (curl) {

       curl_easy_setopt(curl, CURLOPT_URL, "https://jshk.com.cn/ip");

       curl_easy_setopt(curl, CURLOPT_PROXY, "http://219.151.125.106:31615");

       //代理IP地址和端口号

       curl_easy_setopt(curl, CURLOPT_PROXYUSERPWD, "895314XY:24D6YB309ZCB");

       //代理IP的AuthKey和AuthPwd

       curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteMemoryCallback);

       curl_easy_setopt(curl, CURLOPT_WRITEDATA, &resp);

       res = curl_easy_perform(curl);

       curl_easy_cleanup(curl);

       if (res != CURLE_OK) {

           fprintf(stderr, "request failed: %s\n", curl_easy_strerror(res));

       }

   }

}

int main()

{

   string response;

   Proxy(response);

   cout << response << endl;

       return 0;

}
