How to get json data in REST endpoint C#

i set the Transaction response callback url of an API to : https://requestb.in/st4fz3st and it gives me a response ok, on debugging the response process by checking the link https://requestb.in/st4fz3st?inspect the results shown in the image below.
i want to get the json data so i wrote this c# code
string GET(string url)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
try
{
WebResponse response = request.GetResponse();
using (Stream responseStream = response.GetResponseStream())
{
StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
return reader.ReadToEnd();
}
}
catch (WebException ex)
{
WebResponse errorResponse = ex.Response;
using (Stream responseStream = errorResponse.GetResponseStream())
{
StreamReader reader = new StreamReader(responseStream, Encoding.GetEncoding("utf-8"));
String errorText = reader.ReadToEnd();
return errorText;
}
throw;
}
}
protected void Page_Load(object sender, EventArgs e)
{
x = GET(" https://requestb.in/st4fz3st");
Response.Write(x);
}
But what i get is the ok not the RAW BODY which is marked in red.

You can use the api. For example in your case: https://requestb.in/api/v1/bins/st4fz3st/requests
You can parse the result with Newtonsoft.Json. The 'raw body' is body property

How to get http content using an given api key like this in C#?

http://ssw.com/profile/?apikey = skdwkdkfkkdj
I tried to use
public async Task<string> GetFromUriAsync(string requestUri, string token)
{
var client = new HttpClient();
client.BaseAddress = new Uri(BaseUri);
client.DefaultRequestHeaders.Authorization =
new AuthenticationHeaderValue("apikey", "=" + token);
HttpResponseMessage response = await client.GetAsync(requestUri);
response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
return responseBody;
}
Then it returns null
Am I missing something or is it just totally wrong?
Thanks

You're trying to pass the API key in the header information of your HTTP request. What you need to do is just pass that whole URL without any additional header information.
IE: use "http://ssw.com/profile?apikey=abcdef" as the requestUri and send token as null. Also, remove the setting of the client.DefaultRequestHeaders.Authorization property. Authorization was meant to be a user/pass system and not a token-based system.
To test this, download Fiddler 4 (https://www.telerik.com/download/fiddler). Once you have fiddler installed, on the "Composer" tab, you can test different queries you need by putting the URL directly into the URL box and clicking "Execute". You'll then be able to use the inspectors to see the responses and figure out where you need to go from there.
Here are the classes I use for HTTP GET and POST operations:
public static string HTTPGET(string url)
{
try
{
HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url);
request.Timeout = 100000;
HttpWebResponse response = (HttpWebResponse) request.GetResponse();
Stream responseStream = response.GetResponseStream();
if (responseStream != null)
using (StreamReader resStream = new StreamReader(responseStream))
return resStream.ReadToEnd();
return null;
}
catch (Exception e)
{
Console.WriteLine(url);
Console.WriteLine(e);
return null;
}
}
public static string HTTPPOST(string url, string postData)
{
try
{
HttpWebRequest webRequest = (HttpWebRequest) WebRequest.Create(url);
webRequest.Method = "POST";
webRequest.ContentType = "x-www-form-urlencoded";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
using (Stream requestStream = webRequest.GetRequestStream())
requestStream.Write(byteArray, 0, byteArray.Length);
using (Stream responseStream = webRequest.GetResponse().GetResponseStream())
if (responseStream != null)
using (StreamReader responseReader = new StreamReader(responseStream))
return responseReader.ReadToEnd();
return null;
}
catch (Exception e)
{
Console.WriteLine(url);
Console.WriteLine(postData);
Console.WriteLine(e);
return null;
}
}

The magic number in GZip header is not correct. Make sure you are passing in a GZip stream getting this error

i am working on asp.net webform to passing json string on a url for authenticate but getting error in Gzip.
here is my method to post data
private static string GetResponse(string requestData, string url)
{
string responseXML = string.Empty;
try
{
byte[] data = Encoding.UTF8.GetBytes(requestData);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";
request.ContentType = "application/json";
request.Headers.Add("Accept-Encoding", "gzip");
Stream dataStream = request.GetRequestStream();
dataStream.Write(data, 0, data.Length);
dataStream.Close();
WebResponse webResponse = request.GetResponse();
var rsp = webResponse.GetResponseStream();
if (rsp == null)
{
//throw exception
}
using (StreamReader readStream = new StreamReader(new GZipStream(rsp, CompressionMode.Decompress)))
{
responseXML = JsonConvert.DeserializeXmlNode(readStream.ReadToEnd()).InnerXml;
}
}
catch (WebException webEx)
{
//get the response stream
WebResponse response = webEx.Response;
Stream stream = response.GetResponseStream();
String responseMessage = new StreamReader(stream).ReadToEnd();
}
finally
{
}
return responseXML.ToString();
}
getting this error while i am passing the json object and url
enter image description here

c# catch empty Json / 404 error

I have the following code for accessing a Api which returns a Json value. Now it's possible that i try to access the api but nothing is being returned, aka the given ID its trying to search doesnt exist. This ofcourse returns a 404 but i do not know how to handle this error so the code continious on going, now it breaks the program and crashes.
public RootObject GetApi(string url)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
try{
WebResponse response = request.GetResponse();
using (Stream responseStream = response.GetResponseStream()){
StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
var jsonReader = new JsonTextReader(reader);
var serializer = new JsonSerializer();
return serializer.Deserialize<RootObject>(jsonReader);
}
}
catch (WebException ex){
WebResponse errorResponse = ex.Response;
using (Stream responseStream = errorResponse.GetResponseStream()){
StreamReader reader = new StreamReader(responseStream, Encoding.GetEncoding("utf-8"));
String errorText = reader.ReadToEnd();
// log errorText
}
throw;
}
}
This is the button click event where the Url of the api is given.
private void button1_Click(object sender, EventArgs e)
{
result_rTBox.Text = "";
api_Handler api_Handler = new api_Handler();
string spidyApi_itemSearch = "http://www.gw2spidy.com/api/v0.9/json/item-search/";
string Gw2Api_allListings = "https://api.guildwars2.com/v2/commerce/listings/";
string userInput_itemName = userSearchInput_tBox.Text;
string spidyApi_searchIdByName = spidyApi_itemSearch + userInput_itemName;
if (!string.IsNullOrWhiteSpace(userSearchInput_tBox.Text)){
var spidyApi_searchIdByName_result = api_Handler.GetApi(spidyApi_searchIdByName);
var Gw2Api_isItemIdinListing_result = api_Handler.GetApi(Gw2Api_allListings + spidyApi_searchIdByName_result.results[0].data_id);
//result_rTBox.Text = Gw2Api_isItemIdinListing_result.results[0].data_id.ToString();
}
}
First i access the api with string "spidApi_itemSearch" and after that I have and ID that i need to check if exists in the api Gw2Api_allListings. If it doesnt exist, which will happen quite often, it returns nothing with a 404 error. How do i get around of making the code continue even if it returns nothing?
EDIT: code that i have now, still crashes on the break.
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
try
{
var requesting = WebRequest.Create(url);
using (var response = request.GetResponse())
{
using (var responseStream = response.GetResponseStream())
{
StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
var jsonReader = new JsonTextReader(reader);
var serializer = new JsonSerializer();
return serializer.Deserialize<RootObject>(jsonReader);
}
}
}
catch (WebException ex)
{
if (ex.Status == WebExceptionStatus.ProtocolError &&
ex.Response != null)
{
var resp = (HttpWebResponse)ex.Response;
if (resp.StatusCode == HttpStatusCode.NotFound){
}
}
throw;
}
}

Use the HttpStatusCode Enumeration, specifically HttpStatusCode.NotFound
Instead of WebResponse, try using HttpWebResponse
HttpWebResponse errorResponse = we.Response as HttpWebResponse;
if (errorResponse.StatusCode == HttpStatusCode.NotFound) {
// handle the error here
}
Where we is a WebException

Web service request time out issue

I want to interact with a web service, and for this purpose I am using this code.
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(#"http://192.168.2.51/loodappSrv/LoodAppsrv.svc/company/insertcompany?Validation_Token=dc6f3d5e-22c7-405f-abb6-4491de140e7e");
req.Method = "POST";
req.ContentType = #"text/json";
JsonComapnyFormat jcf = new JsonComapnyFormat();
string data = jcf.data();//data in json Format {"companyName":"Alpha","departmentId":3}
using (Stream requestStream = req.GetRequestStream())
{
StreamWriter streamWriter = null;
try
{
//streamWriter = new StreamWriter(requestStream, System.Text.Encoding.Default);
streamWriter = new StreamWriter(requestStream, System.Text.Encoding.Default);
streamWriter.Write(data);
}
catch (Exception ex)
{
throw ex;
}
finally
{
try
{
streamWriter.Close();
requestStream.Close();
streamWriter.Dispose();
streamWriter = null;
requestStream.Dispose();
}
catch
{
}
}
}
HttpWebResponse response = (HttpWebResponse)req.GetResponse();
Stream stream = response.GetResponseStream();
StreamReader reader = new StreamReader(stream);
var result = reader.ReadToEnd();
ViewBag.ABC = result;
return View();
If I Use Fiddler to send POST data on the given URL, it is perfect (sudden response comes out). But when I send same date on the same URL then the message return in an exception "The operation has timed out" at HttpWebResponse response = (HttpWebResponse)req.GetResponse();. Please suggest solutions.

Have you tried what SLaks mentioned ?
The MIME media type for JSON text is application/json.
As can be seen here
