使用 C# 调用我的 REST API

Question

我正在尝试使用简单的 C# GUI 应用程序调用我自己的返回 JSON 的 REST API，并且正在寻找最简单的方法：

http://danielmiessler.com:44821/token/dGVxdWllcm8=

我正在打开一个包含令牌的文件并逐行读取内容以获取 URL 的最后部分：

StreamReader input = new StreamReader(openFileDialog1.OpenFile());

while ((line = input.ReadLine()) != null) {

这将回到文本框：

textBox2.Text += ("\t" + result + "\r\n");

这是我要重现的 Ruby 代码：

# Get our libraries 
require 'httparty'
require 'json'

# Get our input from the command line
input = ARGV[0]

# Loop through the file
File.open("#{input}", "r").each_line do |line|
    # Request the URL
    response = HTTParty.get("http://danielmiessler.com:44821/token/#{line.chomp}")
    # Go through the responses
    case response.code
    when 400
        print "Improper input…\n"
        # Feel free to remove this line if you want to reduce output.
    when 200
        json = JSON.parse(response.body)
        print "Your input is #{json['type']} of the word: #{json['value']}\n"
    when 404
        print "There is no meaning in your token…\n"
        # Feel free to remove this line if you want to reduce output.
    end
end

任何想法如何根据文件中的标记进行调用并输出到文本框？

您可以为此使用HttpClient。

这是一个minimal example，可以帮助您入门：

static void Main(string[] args) 
{ 
    HttpClient client = new HttpClient(); 

    client.GetAsync(_address).ContinueWith( 
        (requestTask) => 
        { 
            HttpResponseMessage response = requestTask.Result; 
            response.EnsureSuccessStatusCode(); 
            response.Content.ReadAsAsync<JsonArray>().ContinueWith( 
                (readTask) => 
                { 
                    Console.WriteLine(
                     "First 50 countries listed by The World Bank..."); 
                    foreach (var country in readTask.Result[1]) 
                    { 
                        Console.WriteLine("   {0}, Country Code: {1}, " +
                            "Capital: {2}, Latitude: {3}, Longitude: {4}", 
                            country.Value["name"], 
                            country.Value["iso2Code"], 
                            country.Value["capitalCity"], 
                            country.Value["latitude"], 
                            country.Value["longitude"]); 
                    } 
                }); 
        }); 
    Console.WriteLine("Hit ENTER to exit..."); 
    Console.ReadLine(); 
}
