我有一个软件的身份验证系统，我向服务器发送GET请求以验证它，然后回显true或false。每当我使用Winsock发送HTTP请求时，我会收到错误：400错误请求并且下面是openresty。任何帮助都将受到赞赏！

void main() {
    WSADATA wsaData;
    SOCKET Socket;
    SOCKADDR_IN SockAddr;
    int lineCount = 0;
    int rowCount = 0;
    struct hostent* host;
    locale local;
    char buffer[10000];
    int i = 0;
    int nDataLength;
    string website_HTML;

    // website url
    string url = "www.mysitewebsite.com/auth/auth.php?hwid=" + hwidPro +
                 "&username=" + Username + "&password=" + Password;

    // HTTP GET
    string get_http =
        "GET / HTTP/1.1\r\nHost: " + url + "\r\nConnection: close\r\n\r\n";

    if(WSAStartup(MAKEWORD(2, 2), &wsaData) != 0) {
        cout << "WSAStartup failed.\n";
        system("pause");
        // return 1;
    }

    Socket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    host = gethostbyname("www.mysite.com");

    SockAddr.sin_port = htons(80);
    SockAddr.sin_family = AF_INET;
    SockAddr.sin_addr.s_addr = *((unsigned long*)host->h_addr);

    if(connect(Socket, (SOCKADDR*)(&SockAddr), sizeof(SockAddr)) != 0) {
        cout << "Could not connect";
        system("pause");
        // return 1;
    }

    // send GET / HTTP
    send(Socket, get_http.c_str(), strlen(get_http.c_str()), 0);

    // recieve html
    while((nDataLength = recv(Socket, buffer, 10000, 0)) > 0) {
        int i = 0;
        while(buffer[i] >= 32 || buffer[i] == '\n' || buffer[i] == '\r') {
            website_HTML += buffer[i];
            i += 1;
        }
    }

    closesocket(Socket);
    WSACleanup();

    const char* result = website_HTML.c_str();
    Log::Msg(result);
    if(website_HTML == "true") {
        authsucsess();

    } else {
        Log::Fatal(result);
        Log::Fatal("无效的登录或HWID");
        exit(0);
    }
}

我已编辑我的帖子，让它成为一个最小的、可复现的例子。希望它更好修改2：我已添加HTTP响应：

你的 GET 请求格式不正确，这是你当前发送的请求：

GET / HTTP/1.1
Host: www.mysitewebsite.com/auth/auth.php?hwid=[...]&username=[...]&password=[...]
Connection: close

应该是这样的：

GET /auth/auth.php?hwid=[...]&username=[...]&password=[...] HTTP/1.1
Host: www.mysitewebsite.com
Connection: close

尝试使用以下代码：

string s_host = "www.mysitewebsite.com";
string s_resource = "/auth/auth.php";
string s_query = "?hwid=" + hwidPro + "&username=" + Username + "&password=" + Password;

string url = s_host + s_resource + s_query;

string get_http = "GET " + s_resource + s_query + " HTTP/1.1\r\n"
    "Host: " + s_host + "\r\n"
    "Connection: close\r\n"
    "\r\n";

...

host = gethostbyname(s_host.c_str());

...

send(Socket, get_http.c_str(), get_http.size(), 0);

...

while((nDataLength = recv(Socket, buffer, sizeof(buffer), 0)) > 0)
{
    website_HTML.append(buffer, nDataLength);
}

...
