寻找使用JSON客户端库REST [英] Looking for a REST with JSON client library

问题描述

我需要连接到供应了JSON通过REST接口的端点。我真的不能找到任何组合这两种技术以协调一致的方式。

I need to connect to an endpoint that serves out JSON via REST interfaces. I can't really find anything that combines these 2 technologies in a coherent manner.

我要寻找那会让我上手很快的库。

I am looking for a library that will let me get started quickly.

推荐答案

您可以使用 Json.Net 库，这扩展类，它使用 DynamicObject

You can use Json.Net library and this extension class that makes use of DynamicObject

一些有用的例子：

public static void GoogleGeoCode(string address)
{
    string url = "http://maps.googleapis.com/maps/api/geocode/json?sensor=true&address=";
    dynamic googleResults = new Uri(url + address).GetDynamicJsonObject();

    foreach (var result in googleResults.results)
    {
        Console.WriteLine("[" + result.geometry.location.lat + "," + 
                                result.geometry.location.lng + "] " + 
                                result.formatted_address);
    }
}

public static void GoogleSearch(string keyword)
{
    string url = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&rsz=8&q=";
    dynamic googleResults = new Uri(url + keyword).GetDynamicJsonObject();

    foreach (var result in googleResults.responseData.results)
    {
        Console.WriteLine(
            result.titleNoFormatting + "\n" + 
            result.content + "\n" + 
            result.unescapedUrl + "\n");
    }
}

public static void Twitter(string screenName)
{
    string url = "https://api.twitter.com/1/users/lookup.json?screen_name=" + screenName;
    dynamic result = new Uri(url).GetDynamicJsonObject();
    foreach (var entry in result)
    {
        Console.WriteLine(entry.name + " " + entry.status.created_at);
    }
}

public static void Wikipedia(string query)
{
    string url = "http://en.wikipedia.org/w/api.php?action=opensearch&search=" + query +"&format=json";
    dynamic result = new Uri(url).GetDynamicJsonObject();

    Console.WriteLine("QUESTION: " + result[0]);
    foreach (var entry in result[1])
    {
        Console.WriteLine("ANSWER: " + entry);
    }
}

编辑：

下面是没有 DynamicObject

public static void GoogleSearch2(string keyword)
{
    string url = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&rsz=8&q="+keyword;

    using(WebClient wc = new WebClient())
    {
        wc.Encoding = System.Text.Encoding.UTF8;
        wc.Headers["User-Agent"] = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727; .NET4.0C; .NET4.0E)";
        string jsonStr = wc.DownloadString(url);
        JObject jObject = (JObject)JsonConvert.DeserializeObject(jsonStr);
        foreach (JObject result in jObject["responseData"]["results"])
        {
            Console.WriteLine(
                result["titleNoFormatting"] + "\n" +
                result["content"] + "\n" +
                result["unescapedUrl"] + "\n");
        }
    }
}
