用用户名和密码调用rest api - 如何

Question

我是新来的api's并通过.NET调用它们

我有一个api:https://sub.domain.com/api/operations？ param = value & param2 = value

api的注释说要授权我需要使用基本的访问身份验证 - 我该怎么做？

我目前有这个代码:

        WebRequest req = WebRequest.Create(@"https://sub.domain.com/api/operations?param=value&param2=value");
        req.Method = "GET";
        //req.Credentials = new NetworkCredential("username", "password");
        HttpWebResponse resp = req.GetResponse() as HttpWebResponse;

但是我得到了401未经授权的错误.

我缺少什么,如何使用基本访问身份验证形成api呼叫？

Answer 1

如果API说要使用HTTP基本身份验证,则需要在请求中添加Authorization标头.我会改变你的代码看起来像这样:

    WebRequest req = WebRequest.Create(@"https://sub.domain.com/api/operations?param=value&param2=value");
    req.Method = "GET";
    req.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes("username:password"));
    //req.Credentials = new NetworkCredential("username", "password");
    HttpWebResponse resp = req.GetResponse() as HttpWebResponse;

当然,更换"username"并"password"使用正确的值.

例如，您还可以使用 RestSharp 库

var userName = "myuser";
var password = "mypassword";
var host = "170.170.170.170:333";
var client = new RestClient("https://" + host + "/method1");            
client.Authenticator = new HttpBasicAuthenticator(userName, password);            
var request = new RestRequest(Method.POST); 
request.AddHeader("Accept", "application/json");
request.AddHeader("Cache-Control", "no-cache");
request.AddHeader("Content-Type", "application/json");            
request.AddParameter("application/json","{}",ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
