vibed:如何处理 POST 请求?

vibed: How can I handle POST request?

谁能帮我处理 POST 请求,我读了 docs,但我不清楚如何处理 POST 请求,我从页面发送到振动服务器。

我写了下一个代码:

import vibe.d;
import std.stdio;

void main()
{

    auto router = new URLRouter;
    router.any("*", &accControl);
    router.any("/my", &action);

    auto settings = new HTTPServerSettings;
    settings.port = 8080;
    settings.bindAddresses = ["::", "127.0.0.1"];

    listenHTTP(settings, router);
    runEventLoop();
}

void accControl(HTTPServerRequest req, HTTPServerResponse res)
{
    res.headers["Access-Control-Allow-Origin"] = "*";
}


void action(HTTPServerRequest req, HTTPServerResponse res)
{
    // how get string from POST request here. And how get JSON object, if server send it.
}

但是我应该使用什么方法来请求?据我了解,expect POST body 正在发送大量其他数据。

POST 请求正在发送 JQuery:

$.post("http://127.0.0.1:8080", "\"answers_result\":777");

所以我需要得到这个 JSON 并将它与 vibed 一起发送到数据库。但是我无法理解如何处理的问题。

主要内容:

auto router = new URLRouter;
router.post("/url_to_match", &action);

listenHTTP(settings, router);

操作:

void action(HTTPServerRequest req, HTTPServerResponse res)
{
    auto answers_result = req.json["answers_result"].to!int;

    // ...
}

或者您可以使用 registerRestInterface.

这是一个示例代码,展示了如何从 vibe.d 中读取 POST 参数:

主要功能:

shared static this()
{
   auto router = new URLRouter;
   router.post("/url_to_match", &action);

   auto settings = new HTTPServerSettings;
   settings.port = 3000;
   listenHTTP(settings, router);
}

操作:

void action(HTTPServerRequest req, HTTPServerResponse res)
{
    // Read first POST parameter named "first_name"
    auto firstName = req.form["first_name"];

    // Read second POST parameter named "last_name"
    auto lastName = req.form["last_name"];

    // Prepare output to be sent to client.
    auto name = "Hello %s, %s".format(lastName, firstName);

    // Send data back to client
    res.writeBody(name);
}

构建程序并 运行 它,要在您的本地计算机上试用它,您可以执行以下简单的 curl 请求:

curl --data "first_name=kareem&last_name=smith" "http://localhost:3000/url_to_match"
