Question

我有这项任务，我必须向外部网站发送POST请求，以便PHP更改和检索一些数据。这是它的工作原理：

首先我去this site。然后，使用Google Chrome浏览器检查网站，然后转到“网络”标签。打开此窗口时，我将 Varmepumpe - luft til luft 从 INGEN 更改为实际网站上的 LITEN 。名称 Energi 现在显示在Network tab。

中

点击 Energi 后，我在标题下看到以下内容：

在请求有效负载下，有大量与能源相关的参数用于计算房屋的节能和类似的东西。您可以更改区域，更改构建年份，更改使用的加热系统等。如何在PHP中使用POST请求更改这些参数，以便将它们发送进行重新计算，以便我可以从外部站点的Network as JSON下的Preview选项卡中检索信息？

以下是预览标签的示例：

CO2Emissions: "380"
energy: {,…}
energyConsumption: "2 881"
energyCost: "2 592"
energyCostAsString: "kr 2 592"
lifetimeCO2Emissions: "11 400"
lifetimeEnergyConsumption: "86 430"
lifetimeSavings: 77760
liftetimeEnergyCostAsString: "kr 77 760"
optimalInitiativeId: "-1"
presentCO2Emissions: "2 343"
presentEnergy: {,…}
presentEnergyConsumption: "24 338"
presentEnergyCost: "21 904"
presentEnergyCostAsString: "kr 21 904"
presentEnergyCostSummary: "..."
presentEnergyRatingImage: "D_5.png"
recommendedInitiativeIds: []
saving: 2592
savingsAsString: "kr 2 592"
tek10Energy: {,…}
upgradedEnergyCostSummary: "..."
upgradedEnergyRatingImage: "C_4.png"

我想将此数据检索为JSON，但看到此数据由请求有效负载下的值更改，我还必须能够在中发送带有新值的请求请求有效负载以检索所需的JSON结果。

这是我到目前为止所尝试的内容，代码主要来自this link。

$url = 'http://energiportalen.no/Energianalyse/MinBolig/?municipality=0111&area=187&yoc=1989&type=2';
$data = array('Area' => '199', 'initiatives' => '["1"]');

// use key 'http' even if you send the request to https://...
$options = array(
    'http' => array(
        'header'  => "Content-type: application/json\r\n",
        'method'  => 'POST',
        'content' => http_build_query($data),
    ),
);
$context  = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) { /* Handle error */ }

var_dump($result);

这样做的结果是 bool（false），因为它可能是错误的代码。

我认为我必须更改＆＃39;标题＆＃39; =＆GT; ＆＃34;内容类型：application / x-www-form-urlencoded \ r \ n＆＃34;，到 application / json ，因为这是我在下看到的“网络”标签中的“请求标题”。如果这是正确的，我真的不知道。

我还添加了

$data = array('Area' => '199', 'initiatives' => '["1"]');

我希望上面的代码行更改请求有效负载下的区域和计划设置，以便我可以检索下的新值网络中的预览。

所以我的问题是：

我如何send参数对此网址发出POST请求并检索位于网络＆gt;下的数据？ Energi＆gt;使用外部网站在Chrome中预览JSON结果。

我位于一个单独的网站上，我想要检索这些数据。

这甚至可能吗？任何帮助表示赞赏。

Answer 1

我认为你要求的是一个PHP方法，它将发布到输出JSON的服务。

这可以在PHP的帮助下完成。示例功能：

  sayHeroName(hero: Hero) {
    hero.speak();
  }

发送POST请求以使用PHP
