如何从ASP.NET C＃中的URL使用json get方法获取响应 [英] How to get response using json get method from a URL in ASP.NET C#

问题描述

我发布了一个json字符串进行付款，付款后重定向到我的成功页面，

在我的成功页面上我需要获取交易详情

按照付款文件我需要使用json Get Method来获取交易细节，传递代码如

I post a json string for payment , after payment it redirects to my success page,
On my success page i need get transaction details
So as per Payment Documentation i need use json Get Method to get the transaction details , passing a code like

"https://sb-open.revenuemonster.my/v3/payment/transaction/qrcode/" + Session["QrCodeWc"].ToString() + "/transactions"

示例链接下面可以看到此网址上的Json数据

https://sb-open.revenuemonster.my/v3/payment/transaction/qrcode / c6c2df354c1e5274a1adc462ffbd96b3 / transactions [ ^ ]



我把代码放在会话中



现在我想知道如何把代码写到Ge t方法从上面的URL获得回复



这是文件Instuction

Example Link Below can see Json data on this url
https://sb-open.revenuemonster.my/v3/payment/transaction/qrcode/c6c2df354c1e5274a1adc462ffbd96b3/transactions[^]

where i put code trough Session

Now i want to know how to write code to Get method to get responses from above URL

This is document Instuction

感谢任何帮助



我尝试过：

Appreciate any help

What I have tried:

string reqUrl = "https://sb-open.revenuemonster.my/v3/payment/transaction/qrcode/" + Session["QrCodeWc"].ToString() + "/transactions";

       var httpWebRequestQR = (HttpWebRequest)WebRequest.Create(reqUrl);
        httpWebRequestQR.ContentType = "application/json";
        httpWebRequestQR.Method = "GET";
        
        using (var streamWriterQR = new
        StreamWriter(httpWebRequestQR.GetRequestStream()))
        {
            string jsonQR = new JavaScriptSerializer().Serialize(new
            {

            });

            streamWriterQR.Write(jsonQR);
        }

        var httpResponseQR = (HttpWebResponse)httpWebRequestQR.GetResponse();
        using (var streamReader = new StreamReader(httpResponseQR.GetResponseStream()))
        {
            var resultsign = streamReader.ReadToEnd();
            string jsonStringsign = resultsign;

            JsonData json = JsonMapper.ToObject(jsonStringsign);
            string tranId = json["item"]["transactionId"].ToString();
           
            
            lblMsg.Text = tranId;
        }

推荐答案

如果您返回了JSON数据，请阅读本文，因为它是为了回答Q& A而写的这些问题：在C＃中使用JSON& VB [ ^ ]

If you have the JSON data returned, then read this article as it was written to answer Q&A questions like these: Working with JSON in C# & VB[^]

我解决了这个问题，一旦使用获取方法就不需要添加Get Streams

以下是解决方案。

I solved the issue, No need to add Get Streams once use Get Methods
Here are the solutions.

var httpWebRequestQR = (HttpWebRequest)WebRequest.Create(reqUrl);
httpWebRequestQR.ContentType = "application/json";
httpWebRequestQR.Method = "GET";
httpWebRequestQR.Headers.Add("Authorization", "Bearer " + accToken);
httpWebRequestQR.Headers.Add("X-Signature", signatureWc);
httpWebRequestQR.Headers.Add("X-Nonce-Str", nonce);
httpWebRequestQR.Headers.Add("X-Timestamp", timestampStr);

var httpResponseQR = (HttpWebResponse)httpWebRequestQR.GetResponse();
using (var streamReader = new StreamReader(httpResponseQR.GetResponseStream()))
{
    var resultQR = streamReader.ReadToEnd();
    string jsonStringsign = resultQR;

    JsonData json = JsonMapper.ToObject(jsonStringsign);
    string txnId = json["items"]["transactionId"].ToString();
    string storeId = json["items"]["store"]["id"].ToString();
    string curType = json["items"]["currencyType"].ToString();
    int ttfee = (int) json["items"]["order"]["amount"];
}
