Discord Webhooks 与 C++

Question

因此，我接受了在 C++ 中进行 Webhooks 的挑战，并且我想获得一些有关发布请求的帮助。这是我目前的代码，我想通过 C++ 中的 post 请求发送嵌入。 这是我的代码以及错误和所有内容，如果您想自己测试一下，网络钩子仍然处于活动状态。我试图故意使用 Windows 库来保留这一切。

#include <winsock2.h>
#include <ws2tcpip.h>
#include <string>

#pragma warning(disable:4996) 
#pragma comment(lib, "ws2_32.lib")

using namespace std;

int Plug(string address, string port, SOCKET* csock) {
    WSADATA WSAData;
    WSAStartup(MAKEWORD(2, 0), &WSAData);

    PADDRINFOA result;
    ADDRINFOA hints;
    ZeroMemory(&hints, sizeof(ADDRINFO));
    hints.ai_family = AF_INET;
    hints.ai_socktype = SOCK_STREAM;
    hints.ai_protocol = IPPROTO_TCP;
    int res = getaddrinfo(address.c_str(), port.c_str(), &hints, &result);
    *csock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    if (SOCKET_ERROR == connect(*csock, (SOCKADDR*)result->ai_addr, sizeof(SOCKADDR))) return WSAGetLastError();
    return 0;
}

void Unplug(SOCKET* csock) {
    closesocket(*csock);
    WSACleanup();
}


string PostRequest(string host, string query, string data) {
    string req = "POST " + query + " HTTP/1.1" + "\r\n";
    req += "Host: " + host + "\r\n";
    req += "Content-Type: application/x-www-form-urlencoded\r\n";
    req += "Content-Length: " + to_string(data.length()) + "\r\n";
    req += "Connection: Close";
    req += "\r\n\r\n" + data + "\r\n\r\n";
    SOCKET s;;
    Plug(host, "80", &s);
    Send(&s, req);
    while (GetAvailable(&s) == 0) Sleep(10);
    string result = Receive(&s);
    //if (result.find("\r\n\r\n") == string::npos && DEBUG) return result;
    //if (result.find("\r\n\r\n") == string::npos) return "PR_INVALID_RESPONSE";
    //result = result.substr(result.find("\r\n\r\n") + 4, string::npos);
    Unplug(&s);
    return result;
}
int main() {
    //https://discordapp.com/api/webhooks/705211476553629747/zwzqZMnTTgLtHBm3kc_DvvD71IW9FfE4ur-PQlkgeZhd56cT7UjSJCWI-V8wPiEUWV2w
    std::cout<<PostRequest("162.159.129.233","/api/webhooks/705249405141516360/s8ioXr6IZEeuPnMi1O37CmY3o5pUZcu6ho7aIJdieSAqgGyTXOZjkOZdMNe1uJre6dto","{'embeds': [{'description': '**ERROR**: `TESTSTRING`\n', 'color': 4508791}]}");
}

但是，当我发出帖子请求时，它无法发送我的内容，而是返回 400。我尝试了更多操作，但我想知道这是否是我的查询？

假设我使用不和谐的实际IP而不是解决它，我最终得到 代替这个

如果你有任何想法，请不要犹豫，把它们写在下面，我对此迷失了很长时间。

您可以使用 D++ 发布到 webhooks：

https://dpp.dev/classdpp_1_1webhook.html

事实上，您可以使用此库做所有事情，而不是滚动自己的解决方案。
