Below mentioned code is for getting cookie from the login url, I am trying to login and saving cookie to send it for further interaction, but I am not getting any cookie that can be passed. Please help
// My Login method::
void login()

webRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), webRequest);
}

string postData = "client_key=" + Constants.CLIENT_KEY + "&email=" + username + "&password=" + password;
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// Add the post data to the web request
postStream.Write(byteArray, 0, byteArray.Length);

How can I retrieve campaign's placements from AdWords through api(.net)?
I'd seen this piece of code, but I can't do something similar via c#.
Also I try to get links through report PLACEMENT_PERFORMANCE_REPORT, but I can't.
public static string GetReport(AdWordsUser user, string customerId)
{
string postData = string.Format("__rdxml={0}", System.Web.HttpUtility.UrlEncode(#"<reportDefinition xmlns=""https://adwords.google.com/api/adwords/cm/v201506"">
<selector>
<fields>CampaignId</fields>

<fields>Clicks</fields>
<fields>Cost</fields>
<fields>FinalUrls</fields>
<predicates>
<field>Impressions</field>
<operator>GREATER_THAN</operator>
<values>0</values>
</predicates>
</selector>
<reportName>Custom Campaign Performance Report</reportName>
<reportType>PLACEMENT_PERFORMANCE_REPORT</reportType>
<dateRangeType>ALL_TIME</dateRangeType>
<downloadFormat>XML</downloadFormat>
</reportDefinition>"));
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("https://adwords.google.com/api/adwords/reportdownload/v201506");
request.Headers.Add("Authorization", "Bearer " + user.OAuthProvider.AccessToken);
request.Headers.Add("developerToken", "MyToken");
request.Headers.Add("clientCustomerId", customerId);
request.Headers.Add("skipReportSummary", "true");
request.Headers.Add("skipReportHeader", "true");
request.Method = "POST";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
request.ContentType = "application/x-www-form-urlencoded";
var requestWriter = request.GetRequestStream();
requestWriter.Write(byteArray, 0, byteArray.Length);
requestWriter.Close();
string responseData = "";
try
{
StreamReader responseReader = new StreamReader(request.GetResponse().GetResponseStream());
responseData = responseReader.ReadToEnd();
responseReader.Close();
request.GetResponse().Close();
}
catch (Exception ex)

I'm new to c#. I'm trying to login to a website, using a c# post request.
Does this code save the cookie actually to the CookieContainer and would it let me use this cookie in other requests also? How would I for example post a get request now with the cookie I saved from the login?
My main code:
private void button1_Click(object sender, EventArgs e)
{
try
{
string userName = textBox1.Text;
string passWord = textBox2.Text;
string postData = "username=" + userName + "&password=" + passWord;
string requestUrl = "http://registration.zwinky.com/registration/loginAjax.jhtml";
post botLogin = new post();
botLogin.postToServer (postData ,requestUrl);
}
catch (Exception ex)
{
MessageBox.Show("Error :" + ex.Message);
}
}
My post class:
public class post
{
public void postToServer(string postData, string requestUrl)
{
HttpWebRequest myHttpWebRequest = (HttpWebRequest)HttpWebRequest.Create(requestUrl);
myHttpWebRequest.Method = "POST";
byte[] data = Encoding.ASCII.GetBytes(postData);
myHttpWebRequest.CookieContainer = new CookieContainer();
myHttpWebRequest.ContentType = "application/x-www-form-urlencoded";
myHttpWebRequest.ContentLength = data.Length;
Stream requestStream = myHttpWebRequest.GetRequestStream();
requestStream.Write(data, 0, data.Length);
requestStream.Close();
HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
Stream responseStream = myHttpWebResponse.GetResponseStream();
StreamReader myStreamReader = new StreamReader(responseStream, Encoding.Default);
string pageContent = myStreamReader.ReadToEnd();
myStreamReader.Close();
responseStream.Close();
myHttpWebResponse.Close();
MessageBox.Show(pageContent);
}
}
You need to share the CookieContainer between the requests and the responses. I have similar code currently working:
public YourClass
{
private CookieContainer Cookies;
public YourClass()
{
this.Cookies= new CookieContainer();
}
public void SendAndReceive()
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(...);
....
request.UserAgent = agent;
request.Method = "GET";
request.ContentType = "text/html";
request.CookieContainer = this.Cookies;
....
this.Cookies = (HttpWebResponse)request.GetResponse().Cookies;
}
}
i'm trying to POST audio file to my Web Service and get Response from Server. I search on Google but no answer for Windows Phone 8. So please help me.
Update 1 Here my code to try Upload Audio file but have error on server
byte[] buffer;
void Upload(Stream fileStream)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri("http://localhost:11111/api/SpeechRecognition?dataType=json"));
request.Method = "POST";
request.ContentType = "multipart/form-data";
request.UseDefaultCredentials = true;
buffer = new byte[(int)fileStream.Length];
request.BeginGetRequestStream(new AsyncCallback(ReadCallback), request);
}
private void ReadCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
// End the operation.
Stream postStream = request.EndGetRequestStream(asynchronousResult);
postStream.Write(buffer, 0, buffer.Length);
postStream.Close();
request.BeginGetResponse(new AsyncCallback(ResponseCallback), request);
}
private void ResponseCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
HttpWebResponse resp = (HttpWebResponse)request.EndGetResponse(asynchronousResult);
Stream streamResponse = resp.GetResponseStream();
StreamReader streamRead = new StreamReader(streamResponse);
string responseString = streamRead.ReadToEnd();
Dispatcher.BeginInvoke(new Action(() => { MessageBox.Show(responseString); }));
// Close the stream object.
streamResponse.Close();
streamRead.Close();
// Release the HttpWebResponse.
resp.Close();
}
In server ASP.NET 4.5 have error that line
await Request.Content.ReadAsMultipartAsync(provider);
I need to make the following code async and awaitable.
I need to get a lot of data from the web server, and then this data will be used to populate the xaml page in my application.
So, I need the DefLogin() method to be awaitable.
Is it possible?
public void DefLogin()
{
postData = "My Data To Post";
var url = new Uri("Url To Post to", UriKind.Absolute);
webRequest = WebRequest.Create(url);
webRequest.Method = "POST";
webRequest.ContentType = "text/xml";
webRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), webRequest);
}
public void GetRequestStreamCallback(IAsyncResult asynchronousResult)
{
webRequest = (HttpWebRequest)asynchronousResult.AsyncState;
Stream postStream = webRequest.EndGetRequestStream(asynchronousResult);
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
postStream.Write(byteArray, 0, byteArray.Length);
postStream.Close();
Debug.WriteLine("Start BEGINGetResponse");
webRequest.BeginGetResponse(new AsyncCallback(GetResponseCallback), webRequest);
}
public void GetResponseCallback(IAsyncResult asynchronousResult)
{
try
{
HttpWebRequest webRequest = (HttpWebRequest)asynchronousResult.AsyncState;
HttpWebResponse response;
response = (HttpWebResponse)webRequest.EndGetResponse(asynchronousResult);
Stream streamResponse = response.GetResponseStream();
StreamReader streamReader = new StreamReader(streamResponse);
string Response = streamReader.ReadToEnd();
streamResponse.Close();
streamReader.Close();
response.Close();
if (Response == "")
{
//show some error msg to the user
Debug.WriteLine("ERROR");
}
else
{
//Your response will be available in "Response"
Debug.WriteLine(Response);
}
}
catch (WebException)
{
//error
}
}
I saw this question on StackOverflow: Converting ordinary Http Post web request with Async and Await, but I could not understand the answer properly.
Please can anyone help? I would be really grateful!
You can use TaskFactory.FromAsync to convert APM to TAP, making a lot of tiny extension methods like this:
public static Task<Stream> GetRequestStreamAsync(this WebRequest request)
{
return TaskFactory.FromAsync(request.BeginGetRequestStream, request.EndGetRequestStream, null);
}
and do the same for WebRequest.GetResponse and (if necessary) Stream.Write, Stream.Flush, etc.
Then you can write your actual logic using async and await without any callbacks:
public async Task DefLoginAsync()
{
postData = "My Data To Post";
var url = new Uri("Url To Post to", UriKind.Absolute);
webRequest = WebRequest.Create(url);
webRequest.Method = "POST";
webRequest.ContentType = "text/xml";
using (Stream postStream = await webRequest.GetRequestStreamAsync())
{
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
await postStream.WriteAsync(byteArray, 0, byteArray.Length);
await postStream.FlushAsync();
}
try
{
string Response;
using (var response = (HttpWebResponse)await webRequest.GetResponseAsync());
using (Stream streamResponse = response.GetResponseStream())
using (StreamReader streamReader = new StreamReader(streamResponse))
{
Response = await streamReader.ReadToEndAsync();
}
if (Response == "")
{
//show some error msg to the user
Debug.WriteLine("ERROR");
}
else
{
//Your response will be available in "Response"
Debug.WriteLine(Response);
}
}
catch (WebException)
{
//error
}
}
How to access the login authentication by the POST DATA in the below and it get from the httpFox to login the website.
