c# - 获取我的 Paypal AccessToken 请求

Question

我正在尝试获取我的 paypal 访问 token 。

我有下一个参数:EndPoint, Client Id, secret, api username, api签名，api密码，应用程序Id。

我需要一个 paypal 客户端才能这样做吗？

我点击了这个链接:https://developer.paypal.com/docs/integration/direct/make-your-first-call/

并尝试过:

private string getAccessToken() {
    var ppClient; // = new paypalClient(); // create a paypal client

    Dictionary<string, object> parameters = new Dictionary<string, object>();

    parameters.Add("Accept", "application/json");
    parameters.Add("Accept-Language", "en_US");
    parameters.Add("grant_type", "client_credentials");

    var result = ppClient.Get("https://api.sandbox.paypal.com/v1/oauth2/token", parameters);

    string accessToken = result["access_token"];
    return accessToken;
}

谢谢大家!

我会推荐使用 RestSharp(只需获取 NuGet 包):-

        if (ServicePointManager.SecurityProtocol != SecurityProtocolType.Tls12) ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; // forced to modern day SSL protocols
        var client = new RestClient(payPalUrl) { Encoding = Encoding.UTF8 };
        var authRequest = new RestRequest("oauth2/token", Method.POST) {RequestFormat = DataFormat.Json};
        client.Authenticator = new HttpBasicAuthenticator(clientId, secret);
        authRequest.AddParameter("grant_type","client_credentials");
        var authResponse = client.Execute(authRequest);
