C语言运行HTTP代码示例

1. #include
2. #include
3. #include
4. #include"curl/curl.h"
5. usingnamespace std;
6. staticsize_tWriteMemoryCallback(void* ptr,size_t size,size_t nmemb,void* stream){
7. size_t nsize = size * nmemb;
8. string* strdata =(string*)stream;
9. if(strdata)
10. strdata->append((constchar*)ptr, nsize);
11. return nsize;
12. }
13. voidProxy(string& resp){
14. CURL* curl = curl_easy_init();
15. CURLcode res;
16. if(curl){
17. curl_easy_setopt(curl, CURLOPT_URL,"https://ip.cn/api/index?ip=&type=0");
18. curl_easy_setopt(curl, CURLOPT_PROXY,"http://代理IP:端口号");
19. curl_easy_setopt(curl, CURLOPT_PROXYUSERPWD,"请改成您的Key:请改成您的AuthPwd");
20. curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION,WriteMemoryCallback);
21. curl_easy_setopt(curl, CURLOPT_WRITEDATA,&resp);
22. res = curl_easy_perform(curl);
23. curl_easy_cleanup(curl);
24. if(res != CURLE_OK){
25. fprintf(stderr,"request failed: %s\n", curl_easy_strerror(res));
26. }
27. }
28. }
29. int main(){
30. string response;
31. Proxy(response);
32. cout << response << endl;
33. return0;
34. }
35. 嵌入即可使用HTTP隧道
