text .net核心调用api（使用oauth 2.0）

Posted 2021-05-02

call api:

public TokenModelResponse GetToken(string clientId, string secret)
{

    string url = _configuration.GetSection("AppConfig")["TokenApiUrl"];
    HttpClient client = new HttpClient();
    client.BaseAddress = new Uri(url);

    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(
        new MediaTypeWithQualityHeaderValue("application/json"));

    TokenModel tokenModel = new TokenModel()
    {
        ClientId = clientId,
        Secret = secret
    };
    var tokenPostModel = JsonConvert.SerializeObject(tokenModel);
    // List data response.
    HttpResponseMessage response = client.PostAsync("/api/Token/Authenticate", new StringContent(tokenPostModel.ToString(), Encoding.UTF8, "application/json")).Result;  // Blocking call! Program will wait here until a response is received or a timeout occurs.
    if (response.IsSuccessStatusCode)
    {
        // Parse the response body.
        var dataObjects = response.Content.ReadAsAsync<TokenModelResponse>().Result;  //Make sure to add a reference to System.Net.Http.Formatting.dll
        return dataObjects;
    }
    else
    {
        Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
        return new TokenModelResponse { Message = "Fail to get token from server" };
    }

    //Make any other calls using HttpClient here.

    //Dispose once all HttpClient calls are complete. This is not necessary if the containing object will be disposed of; for example in this case the HttpClient instance will be disposed automatically when the application terminates so the following call is superfluous.
    
}

call api with oauth 2.0:

public ValidateLoginPassword GetUserDetails(ValidateLoginPassword.In input)
{
    string url = _configuration.GetSection("AppConfig")["TokenApiUrl"];
    HttpClient client = new HttpClient();
    client.BaseAddress = new Uri(url);

    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(
        new MediaTypeWithQualityHeaderValue("application/json"));

    ValidateLoginPassword.In inputModel = new ValidateLoginPassword.In()
    {
        in_password = input.in_password,
        in_accountcode = input.in_accountcode,
        in_login_id = input.in_login_id
    };

    var postModel = JsonConvert.SerializeObject(inputModel);

    var request = new HttpRequestMessage()
    {
        RequestUri = new Uri(url+"/api/DickerData/GetUserDetails"),
        Method = HttpMethod.Get,
        Content = new StringContent(postModel.ToString(), Encoding.UTF8, "application/json"),
    };

    TokenModelResponse token = GetToken("client", "RGlja2VyITIzUGFzc3cwcmQ=");

    request.Headers.Add("Authorization", $"{token.Token_Type} {token.Access_Token}");

    // List data response.
    HttpResponseMessage response = client.SendAsync(request).Result;
    client.Dispose();
    if (response.IsSuccessStatusCode)
    {
        // Parse the response body.
        var dataObjects = response.Content.ReadAsAsync<ValidateLoginPassword>().Result;
        return dataObjects;
    }
    else
    {
        Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
        return new ValidateLoginPassword { System_msg = "Fail to get user details from api" };
    }
