this.Request_url = url;
GetAPIToken(Username, Password, Request_url);
}
private static async void GetAPIToken(string userName, string password, string apiBaseUri)
{
try
{
using (var client = new HttpClient())
{
//setup client
client.BaseAddress = new Uri(apiBaseUri);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.ASCII.GetBytes($"{userName}:{password}")));
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
//send request
var responseMessage = await client.GetStringAsync(apiBaseUri);
}
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
}
}
}
}

you need to get RestSharp for this to work 您需要获得RestSharp才能运行
var client = new RestClient("https://api.intrinio.com/companies?ticker=AAPL");
var request = new RestRequest(Method.GET);
request.AddHeader("cache-control", "no-cache");
request.AddHeader("authorization", "Basic MGU0NWIxZmIwZDFlMGNkMDEzY2Y2Y2I5MmRlNjk2N2M6MjNjYjM3OTQ3ZmFmMjQ0OWI1MWRjMWQ1NGU2ZGE1Zjc=");
IRestResponse response = client.Execute(request);
and you can try to convert it to an object by 您可以尝试通过以下方式将其转换为对象
try
{
dynamic x = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(response.Content, new Newtonsoft.Json.JsonSerializerSettings() { NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore });
return x;
}
catch (Exception ex)
{
Console.WriteLine(ex);
return null;
}
and i do recommend of using http://json2csharp.com/ to create your C# Object 我建议使用http://json2csharp.com/创建您的C#对象

To get the Value that is used for authorization you can use this method 要获取用于授权的值,可以使用此方法
public static string Base64Encode(string key)
{
var value = System.Text.Encoding.UTF8.GetBytes(key);
return System.Convert.ToBase64String(value);
}
to get the exact value make sure the username and password are concatenated, (username first , password second) and then passed to the method 要获取确切的值,请确保用户名和密码已连接(首先是用户名,然后是密码),然后将其传递给方法
