在Razor網頁中使用JSON Web服務

我一直在關注Mike Brinds指南，以在網頁中使用JSON剃鬚刀。在Razor網頁中使用JSON Web服務

唯一的區別是，他的示例使用「foreach」循環，但我的JSON返回僅返回單個值參數。下面的代碼不會出錯，但它不會返回屏幕上的值。任何幫助，將不勝感激......

@{ 
var client = new WebClient(); 
var json = client.DownloadString("http://api.wunderground.com/api/xxxxxxxx/conditions/q/FL/Orlando.json"); 
var search = Json.Decode(json); 
} 

<!DOCTYPE html> 

<html lang="en"> 
<head> 
    <meta charset="utf-8" /> 
    <title></title> 
</head> 
<body> 

<h2>The current temperature is </h2> 
<h3>@search.temp_f</h3> 


</body> 
</html>

而這裏的JSON響應：

上面加入JSON – beauXjames

JSON響應提供返回值的副本。謝謝 – Gavin5511

您正在尋找在錯誤的地方的價值。 temp_f不是外部對象的一部分;它是current_observation對象的一部分。

改變這一行：

<h3>@search.temp_f</h3>

這樣：

<h3>@search.current_observation.temp_f</h3>
