调用payurestapi返回html而不是json响应

我试图发布一个订单到PayuPaymentGateway,使用Rest客户端工具,比如PostMan,我也遇到了同样的问题。

我试着用C#发布,订单创建成功,但是响应并不像预期的那样,它应该是一个json对象,包含插入的订单id和重定向url,但当前是html响应!

代码响应:

 public IRestResponse<CreateOrderResponseDTO> CreateOrder(CreateOrderDTO orderToCreate)
    {

        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

        var actionUrl = "/api/v2_1/orders/";

        var client = new RestClient(_baseUrl);

        var request = new RestRequest(actionUrl, Method.POST)
        {
            RequestFormat = DataFormat.Json
        };

        request.AddJsonBody(orderToCreate);


        request.AddHeader("authorization", $"Bearer {_accessToken}");
        request.AddHeader("Content-Type", "application/json");

        var response = client.Execute<CreateOrderResponseDTO>(request);

        if (response.StatusCode == HttpStatusCode.OK)
        {
            return response;
        }

        throw new Exception("order not inserted check the data.");


    }

我的C代码使用内置 WebRequest 同时返回相同的html:

 public string Test(string url, CreateOrderDTO order)
    {
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
        httpWebRequest.ContentType = "application/json";
        httpWebRequest.Accept = "application/json";

        httpWebRequest.Method = "POST";
        httpWebRequest.Headers.Add(HttpRequestHeader.Authorization, "Bearer " + _accessToken);

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {

            streamWriter.Write(new JavaScriptSerializer().Serialize(order));
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }
    }

有人能告诉我这里遗漏了什么吗?

经过一些尝试,我发现payurestapi返回 302 (找到)也 ResponseUri OK 200 一如预期。

默认情况下,rest客户端会自动重定向到这个url,因此我收到了支付页面的html内容。

解决方案是:

client.FollowRedirects = false;

另外,我想补充一点,上面Mohammad的回答是正确的,因为我们需要将AllowAutoRedirect设置为false。我一直试图在一个控制台应用程序中实现PayU LatAM WebCheckout,我也面临着类似的问题。我从这里给出的答案中得到了一些启发: How to get Location header with WebClient after POST request

根据答案,我写了一个示例代码:

public class NoRedirectWebClient : WebClient
{
    protected override WebRequest GetWebRequest(Uri address)
    {
        var temp = base.GetWebRequest(address) as HttpWebRequest;
        temp.AllowAutoRedirect = false;
        return temp;
    }
}

在创建了上面的类之后,我在Main方法中编写了以下代码:

var request = MakeRequestLocation(new NoRedirectWebClient());
var psi = new ProcessStartInfo("chrome.exe");

psi.Arguments = request.ResponseHeaders["Location"];
Process.Start(psi);

我现在在同一个类中调用函数MakeRequestLocation。

private static WebClient MakeRequestLocation(WebClient webClient)
{
    var loginUrl = @"https://sandbox.checkout.payulatam.com/ppp-web-gateway-payu/";
    NameValueCollection formData = new NameValueCollection
    {
        {"ApiKey", "4Vj8eK4rloUd272L48hsrarnUA" },
        {"merchantId", "508029" },
        {"accountId", "512321" },
        {"description", "Test PAYU" },
        {"referenceCode", "SomeRandomReferenceCode" },
        {"amount", "2" },
        {"tax", "0" },
        {"taxReturnBase", "0" },
        {"currency", "USD" },
        {"signature", "Signature generated via MD5 sum" },
        {"buyerFullName", "test" },
        {"buyerEmail", "test@test.com" },
        {"responseUrl", @"http://www.test.com/response" },
        {"confirmationUrl",  @"http://www.test.com/confirmation" }
    };
    webClient.UploadValues(loginUrl, "POST", formData);

    return webClient;
}

在postman中,解决方案是关闭重定向,如下图所示:
