我如何处理邮件请求？

Question

有人能帮我处理POST请求吗?我读了文档，但我不清楚如何处理从页面发送到vibed服务器的POST请求。

我写了下一段代码：

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.
}

但是我应该用什么方法来做req呢？据我所知，POST机构正在发送大量其他数据。

POST请求是用JQuery发送的：

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

所以我需要得到这个JSON，然后用vibed发送给DB。但问题是我不知道该怎么处理。

Answer 1

主要是：

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;

    // ...
}

或者你可以使用registerRestInterface。

Answer 2

下面是演示如何从vibe.d读取POST参数的示例代码：

主要职能：

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"
