Question

我正在尝试获取paypal的访问令牌。

我有下一个参数：EndPoint，Client Id，secret，api username，api signature，api password，application Id

我需要PayPal客户才能这样做吗？

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

并尝试：

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！

我建议使用RestSharp（只需抓住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);

有点迟到，但是遇到了类似的问题。最后，我不得不使用“基本”身份验证实现来从PayPal中获取详细信息。这是我的令牌收集器类。唯一真正需要做的就是用我的Paypal设置中生成的2个paypal client_Id和Secret字符串替换我的PayPal选项注入。

忽略我的AccessToken返回类型，它只是我编写的PoCo，而ReadToObject只是使用newtonsoft的简单反序列化器。真正的好东西返回到“结果”字符串。

希望这会有所帮助！

    public sealed class PaymentTokenServer : IPaymentTokenServer
{
    private readonly List<KeyValuePair<string, string>> tokenServerPairs = new List<KeyValuePair<string, string>>();

    private PayPalOptions payPalOptions;

    public PaymentTokenServer(IOptions<PayPalOptions> paypalOptions)
    {
        this.payPalOptions = paypalOptions.Value;

       this.tokenServerPairs.Add(new KeyValuePair<string, string>("grant_type", "client_credentials"));
    }

    public AccessToken GetToken()
    {
        var content = new FormUrlEncodedContent(this.tokenServerPairs);
        ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;

        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri(this.payPalOptions.TokenServerUrl);
            client.DefaultRequestHeaders.AcceptLanguage.Add( new StringWithQualityHeaderValue("en_US"));

            var base64String = Convert.ToBase64String(Encoding.ASCII.GetBytes($"{this.payPalOptions.ClientId}:{this.payPalOptions.Secret}"));
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", base64String);

            var response = client.PostAsync("", content).Result;

            var result = response.Content.ReadAsStringAsync().Result;

            return result.ReadToObject<AccessToken>();
        }
    }
}
