Windows 安装方法：
CMake 1.32+，生成过程会将 vcpkg 下载好，配置到系统环境变量，然后用 vcpkg 安装依赖库（github 上有列出需要的依赖库）。
Github 上的示例不全面，一开始不知道如何序列化输出 json，经过一番研究和谷歌，这里给一个示例：
#include <cpprest/http_client.h>
#include <cpprest/filestream.h>
//#include <boost/regex.hpp>
#include <string>
//#pragma comment(lib, "C:/Program Files/boost_1_72_0/bin.v2/libs/regex/build/msvc-14.2/release/address-model-64/link-static/threading-multi/libboost_regex-vc142-mt-x64-1_72.lib")
#pragma comment(lib, "C:/cpprestsdk/Build_x64/Binaries/Debug/cpprest142_2_10d.lib")
using namespace utility;
using namespace web;
using namespace web::http;
using namespace web::http::client;
using namespace concurrency::streams;
int main()
{
http_client raw_client(U("https://message.bilibili.com/api/tooltip/query.list.do"));
http_request request(methods::GET);
request.headers().add(header_names::accept, L"application/json");
request.headers().add(header_names::user_agent, L"User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.130 Safari/537.36");
request.headers().add(header_names::accept_encoding, L"gzip, deflate, br");
pplx::task<json::value> requestTask = raw_client.request(request).then([](http_response response) { return response.extract_json(); });
std::wcout << requestTask.get().serialize() << std::endl;
return 0;
}
当然也可以不用 lambda 风格，直接：
std::wcout << raw_client.request(request)
.get().extract_json().get().serialize() << std::endl;
