如何从.net控制台调用JSON WebService

本文关键字：调用 JSON WebService 控制台 net | 更新日期: 2023-09-27 18:17:51

我正在尝试在c#控制台应用程序中使用JSON web服务。web服务使用HTTP基本身份验证。我无法在控制台应用程序中访问。

代码示例……

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(@"https://0000.000.0.000:0000/hrms/rest/login");
request.Method = "POST";
request.ContentType = @"application/json";
//request.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes("sharads:hrms123"));
HttpWebResponse resp = request.GetResponse() as HttpWebResponse;

如何从.net控制台调用JSON WebService

可以使用HttpClient向JSON Webservice发送HTTP请求。例如

HttpClient httpClient = new HttpClient();
httpClient.BaseAddress = new Uri(url);
httpClient.DefaultRequestHeaders.Authorization = 
    new AuthenticationHeaderValue(
        "Basic", 
        Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(string.Format("{0}:{1}", "yourusername", "yourpwd"))));

HttpResponseMessage reponse = httpClient.GetAsync("api/enumproducts/GetAll").Result;
if (reponse.IsSuccessStatusCode)
{
var enumProducts = reponse.Content.ReadAsAsync<List<EnumProduct>>().Result;
}

HttpClient也支持POST动作。要了解更多细节，您可以查看这篇博客文章
