curl get命令行下请求正常，c++请求失败

Question

一个http get请求的用法

curl工具命令行运行正常，请求网址返回welcome to the photoshop API

请问怎么用c++怎么实现？下面执行出来是空的,什么也没获取到，写法有没有什么问题呢

#include <iostream>
#include <curl/curl.h>
using namespace std;
/* 不考虑任何异常的情况, 简单的get请求 */
/***
 *  buffer 		接收数据所在的缓冲区
 * 	size		要读取的字节数
 *  count		读写size长度的数据count次
 *  response	用户自定义文件指针
 */
size_t getUrlResponse(char* buffer, size_t size, size_t count, string* response) {
	size_t recv_size = size * count;
	response->clear();
	response->append(buffer);
	return recv_size;
}

string get(const string& url) {
	// 请求数据
	string response;
	// easy handle声明
	CURL *handle;
	// 初始化handle
	handle = curl_easy_init();
	// 设置url

	//设置curl的请求头

        if (0 == strncmp(url, "https:", 6))
        {
            curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, false);
            curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, false);
        }

如果是https，需要添加这些配置，最简单的就是不验证证书
