结构体
cpp
struct HttpRequestMsg
{
    EHttpTypes requestType;//请求类型
    std::string requestBody;//请求报文的body内容
    std::unordered_map<std::string, std::string> requestHeader;//请求报文的头部信息，Host为必须项
    std::string requestUri;//请求报文的Uri
    size_t receiveSize = 4096;//接收信息的最大长度
};
struct HttpResponseMsg
{
    int responseCode;//响应码
    std::unordered_map<std::string, std::string> responseHeader;//响应报文头部信息
    std::string responseBody;//响应报文body内容
    std::string version;//版本号
    std::string status;//状态
};
接口参数描述
void SetHttpType(EHttpTypes type);
EHttpTypes GetHttpType();		type：http请求类型，如Get、Post设置/获取Http请求类型
void SetHttpRequestHeader(std::unordered_map<std::string, std::string> requestHeader);
std::unordered_map<std::string, std::string> GetHttpRequestHeader();		requestHeader：请求报文头部信息，Host为必须项设置/获取请求报文头部信息
void SetHttpRequestBody(std::string& body);
std::string GetHttpRequestBody();		body：请求报文body内容设置/获取请求报文body内容
void SetHttpRequestUri(std::string& uri);
std::string GetHttpRequestUri();		uri：请求报文uri设置/获取uri
HttpResponseMsg Start(std::error_code& ec);进行Http请求
void Start(std::function<void(const HttpResponseMsg&, const std::error_code&)> callback);callback：异步回调函数进行http异步请求
HttpResponseMsg Start(HttpRequestMsg request, std::error_code& ec);request：自定义请求报文信息进行Http请求
std::string BuildRequestPacket();构建请求报文
void SetServerType(std::string& value);value：服务类型，“http”或“https”设置请求服务类型

描述：可通过自定义报文信息进行Http或Https请求 示例代码：

cpp
void Http::HttpsGet()
{
	std::error_code ec;
	NHttpClientPtr m_HttpClient = NNetWorkManager::CreateHttpClient();
	m_HttpClient->SetHttpType(EHttpTypes::HT_GET);
	std::string uri = "http://www.example.com";
	m_HttpClient->SetHttpRequestUri(uri);
	std::unordered_map<std::string, std::string> header1;
	header1["Host"] = "www.example.com";
	header1["Connection"] = "close";
	m_HttpClient->SetHttpRequestHeader(header1);
	std::string type = "https";
	m_HttpClient->SetServerType(type);
	HttpResponseMsg hr = m_HttpClient->Start(ec);
}
cpp
void Http::HttpsGetAsync(NActorPtr actor)
{
    std::error_code ec;
    NHttpClientPtr m_HttpClient = NNetWorkManager::CreateHttpClient();
    m_HttpClient->SetHttpType(EHttpTypes::HT_GET);
    std::string uri = "http://www.baidu.com";
    m_HttpClient->SetHttpRequestUri(uri);
    std::unordered_map<std::string, std::string> header1;
    header1["Host"] = "www.baidu.com";
    header1["Connection"] = "close";
    m_HttpClient->SetHttpRequestHeader(header1);
    std::string type = "https";
    m_HttpClient->SetServerType(type);

    m_HttpClient->Start(std::bind(&Http::HttpHandle, this, std::placeholders::_1, std::placeholders::_2));
}
void Http::HttpHandle(const HttpResponseMsg& msg, const std::error_code& ec)
{
    if (!ec)
    {
        LogEngine("Version: %s", msg.version.c_str());
        LogEngine("Response Code: %d", msg.responseCode);
        LogEngine("Status: %s", msg.status.c_str());
        LogEngine("Header: ");
        for (auto header : msg.responseHeader) {
            LogEngine("%s : %s", header.first.c_str(), header.second.c_str());
        }

        if (msg.responseBody.length() < 500)
        {
            LogEngine("Body: %s", msg.responseBody.c_str());
        }
        else
        {
            LogEngine("The content of the request body is too long. If you want to view it, please enable log output in the code");
            //LogEngine("Body: %s", msg.responseBody.c_str());
        }
    }
    else
    {
        LogEngine("异步操作异常， 错误码:%s", ec.message().c_str());
    }
