Visual Stdio设置：
关闭预编译头：项目->属性->C/C++->预编译头->不使用预编译头
关闭安全警告：项目->属性->C/C++->预处理器->预处理器定义->添加 _CRT_SECURE_NO_WARNINGS

目前实现的http动作有：GET POST HEAD OPTIONS PUT DELETE

cout << resp.status << endl;
cout << resp.GetText() << endl;

Put上传文件

Response resp = Put("http://httpbin.org/put", "C:\\Users\\jack\\Desktop\\key.txt");
cout << resp.status << endl;
cout << resp.GetText() << endl;

Get带cookie访问网页

map<string, string> header;
string cookie = "BAIDUID=B066E871294A61BE394DE24FFA475653:FG=1; BIDUPSID=B066E871294A61BE9EF72E101F79BF87; PSTM=1578882286;";
Response resp = Get("https://pan.baidu.com/disk/home",header,cookie);
cout << resp.GetText() << endl;

设置代理

map<string, string> options;
map<string, string> header;
options["proxy"] = "http=http://122.51.49.88:8888";
try{
    Response resp = Get("http://pv.sohu.com/cityjson",header , "", options);
    cout << resp.status << endl;
}
catch (const char *msg){
    cout << msg << endl;
}

自定义Http Header

map<string, string> header;
map<string, string> options;
options["timeout"] = "5000";
header["name"] = "cpp";
header["age"] = "14"; header["User-Agent"] = "Cpp Brower"
Response resp = Get("http://httpbin.org/headers",header);
cout << resp.status << endl;
cout << resp.GetText() << endl;

上传文件

map<string, string> header;
map<string, string> data;
map<string, string> files;
data["key"] = "something";
data["submit"] = "Submit"; //form表单的其他要上传的数据，如账号密码。
files["file"] = "C:\stdafx.h"; //form表单中的文件字段。
Response resp = Post(url,data,files);
cout << resp.status << endl;
cout << resp.GetText() << endl;
