I'm trying to integrate with a payment gateway (PagSeguro), according to the documentation, I must use the Accept Header "application/vnd.pagseguro.com.br.v3+json;charset=ISO-8859-1".
Trying with the code not work:
HttpClient.DefaultRequestHeaders.Clear();
HttpClient.DefaultRequestHeaders.Add("Accept", "application/vnd.pagseguro.com.br.v3+json;charset=ISO-8859-1");
var content = new StringContent(json, Encoding.Default, "application/json");
var response = await HttpClient.PostAsync(enderecoPreApprovals, content);
var responsestr = await response.Content.ReadAsStringAsync();
I also tried using the same code from documentation:
var client = new RestClient(url) {Timeout = -1};
var request = new RestRequest(Method.POST);
request.AddHeader("Content-Type", "application/json");
request.AddHeader("Accept", "application/vnd.pagseguro.com.br.v3+json;charset=ISO-8859-1");
request.AddParameter("application/json", content, ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
and using flurl:
var response = await addresPreApprovals
.WithHeader("Accept", "application/vnd.pagseguro.com.br.v3+json;charset=ISO-8859-1")
.WithHeader("Content-Type", "application/json")
.PostJsonAsync(adesaoDto);
All the responses are Accept header field is mandatory.. It's like Accept Header is not recognized.
The problem is not in API why i tried using Postman and Insomnia and it's works perfectly.
The problem occurs because of the space between the semicolon (;) and the word charset. We were unable to make it work in .NET 3.1 and there is even an issue on github, indicating that it is not a problem, an implementation of the RFC 7231 specification. Whenever a string "var1 = val1; var2 = val2", o is indicated. NET converts to "var1 = val1; var2 = val2". However, in .NET 5.0, an implementation was released that allows entering a raw string. Another option, according to an old post, is to create something with .NET Framework 4.5
In .NET 5.0
var acceptValue = "application/vnd.pagseguro.com.br.v1+json;charset=ISO-8859-1";
var requestMessage = new HttpRequestMessage(HttpMethod.Post, urlApprovals);
requestMessage.Headers.TryAddWithoutValidation("accept", acceptValue);

Probably duplicate question but I couldn't find an answer for my problem. I have this code to call a web service:
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://172.21.122.1:5001/autocomplete");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
//tried this too: httpWebRequest.Accept = "gzip, deflate";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
streamWriter.Write("{ \"message\" : \"mü\" }");
streamWriter.Flush();
streamWriter.Close();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
response = "";
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
response = streamReader.ReadToEnd();
}
But no matter what Encoding I tried with StreamReader() c'tor, I get this response or worse: {"words":["m\u00fc\u015fteri","m\u00fc\u015fterisiyim""]}
When I use Postman or SoapUI to call the same service with the same request: {"message": "mü"},
response looks ok: {"words": ["müşteri","müşterisiyim"]}
Strange thing is: The same code works OK with many other services. It is only this specific service that the reponse is not correctly encoded. We believe there is a programming error with the service, but what I wonder is how Postman or SoapUI handles this. There should be a control in their code and if the response contains "\uxxxx", then Postman or SoapUI decodes it again.
I've checked all request / response headers in Postman and SoapUI with no luck. What can be the reason?
You have to make sure that your request is encoded correctly:
Set the Content Type to:
httpWebRequest.ContentType = "application/json;charset=UTF-8";
Check if request body is also UTF-8 encoded. Set the StreamWriter encoding to UTF-8 as well:
...
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream(), Encoding.UTF8))
...
If you are getting the request content from other source, make sure to read it also using UTF-8 encoding.
Regex.Unescape(response) worked like a charm, thanks JosefZ!
Im using ASP.Net Core 2. I need to update a user in a Azure AD with Microsofts Graph API. The API documentation states that i should send the properties of the user in the body and specify the user in the URL like so:
https://graph.windows.net/myorganization/users/{user_id}?api-version
The documentation states that it should be a PATCH request. But HTTPRequestMessage does not accept PATCH as a HttpMethod. What is the proper way to make a PATCH request with asp.net core 2?
When i google i find that all answers suggests using JsonPatch, but that is a format that is not supported by Microsoft Graph API.
This is what i have so far....
var client = new HttpClient();
var requestUri = $"{_azureAdOptions.GraphInstance}/{_azureAdOptions.GraphVersion}/{_azureAdOptions.Domain}/users/me";
var request = new HttpRequestMessage(HttpMethod., requestUri);
var accessToken = await _authenticationHelper.GetAccessTokenAsync();
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
var response = await client.SendAsync(request);
var responseString = await response.Content.ReadAsStringAsync();
Given the nature of Http, and the craziness of developers, you can create your own http server with custom methods. The class HttpMethod was created with this in mind allowing you to specify the method as string:
var method = new HttpMethod("PATCH"); // Patch
var request = new HttpRequestMessage(method , requestUri); // Use patch
Note: The new version of HttpClient comes with Patch method by default.
I have implemented the custom security on my reporting services 2016 and it displays the login page once the URL for reporting services is typed on browser URL bar (either reports or reportserver)
I am using the following code to pass the Credentials
when i use the code WITHOUT my security extension it works and looks like this
ICredentials _executionCredentials;
CredentialCache myCache = new CredentialCache();
Uri reportServerUri = new Uri(ReportServerUrl);
myCache.Add(new Uri(reportServerUri.GetLeftPart(UriPartial.Authority)),
"NTLM", new NetworkCredential(MyUserName, MyUserPassword));
_executionCredentials = myCache;
when i use the code WITH the security extension it doesnt work and looks like this
ICredentials _executionCredentials;
CredentialCache myCache = new CredentialCache();
Uri reportServerUri = new Uri(ReportServerUrl);
myCache.Add(new Uri(reportServerUri.GetLeftPart(UriPartial.Authority)),
"Basic", new NetworkCredential(MyUserName, MyUserPassword));
_executionCredentials = myCache;
and i get an Exception saying "The response to this POST request did not contain a 'location' header. That is not supported by this client." when i actually use this credentials
Is "basic" the wrong option ?
Have anyone done this ?
Update 1
Well it turns out that my SSRS is expecting an Authorisation cookie
which i am unable to pass (according to fiddler, there is no cookie)
HttpWebRequest request;
request = (HttpWebRequest)HttpWebRequest.Create("http://mylocalcomputerwithRS/Reports_SQL2016/api/v1.0");
CookieContainer cookieJar = new CookieContainer();
request.CookieContainer = cookieJar;
Cookie authCookie = new Cookie("sqlAuthCookie", "username:password");
authCookie.Domain = ".mydomain.mylocalcomputerwithRS";
if (authCookie != null)
request.CookieContainer.Add(authCookie);
request.Timeout = -1;
HttpWebResponse myHttpWebResponse = (HttpWebResponse)request.GetResponse();
That's how I got it (SSRS 2017; api v2.0). I took the value for the "body" from Fiddler:
var handler = new HttpClientHandler();
var httpClient = new HttpClient(handler);
Assert.AreEqual(0, handler.CookieContainer.Count);
// Create a login form
var body = new Dictionary<string, string>()
{
{"__VIEWSTATE", "9cZYKBmLKR3EbLhJvaf1JI7LZ4cc0244Hpcpzt/2MsDy+ccwNaw9hswvzwepb4InPxvrgR0FJ/TpZWbLZGNEIuD/dmmqy0qXNm5/6VMn9eV+SBbdAhSupsEhmbuTTrg7sjtRig==" },
{"__VIEWSTATEGENERATOR", "480DEEB3"},
{ "__EVENTVALIDATION", "IS0IRlkvSTMCa7SfuB/lrh9f5TpFSB2wpqBZGzpoT/aKGsI5zSjooNO9QvxIh+QIvcbPFDOqTD7R0VDOH8CWkX4T4Fs29e6IL92qPik3euu5QpidxJB14t/WSqBywIMEWXy6lfVTsTWAkkMJRX8DX7OwIhSWZAEbWZUyJRSpXZK5k74jl4x85OZJ19hyfE9qwatskQ=="},
{"txtUserName", "User"},
{"txtPassword", "1"},
{"btnLogin","Войти"}
};
var content = new FormUrlEncodedContent(body);
// POST to login form
var response = await httpClient.PostAsync("http://127.0.0.1:777/ReportServer/Logon.aspx", content);
// Check the cookies created by server
Assert.AreEqual(HttpStatusCode.OK, response.StatusCode);
var cookies = handler.CookieContainer.GetCookies(new Uri("http://127.0.0.1:777/ReportServer"));
Assert.AreEqual("sqlAuthCookie", cookies[0].Name);
// Make new request to secured resource
var myresponse = await httpClient.GetAsync("http://127.0.0.1:777/Reports/api/v2.0/Folders");
var stringContent = await myresponse.Content.ReadAsStringAsync();
Console.Write(stringContent);
As an alternative you can customize SSRS Custom Security Sample quite a bit.
I forked Microsoft's Custom Security Sample to do just what you are describing (needed the functionality at a client long ago and reimplemented as a shareable project on GitHub).
https://github.com/sonrai-LLC/ExtRSAuth
I created a YouTube walkthrough as well to show how one can extend and debug SSRS security with this ExtRSAuth SSRS security assembly https://www.youtube.com/watch?v=tnsWChwW7lA
TL; DR; just bypass the Microsoft example auth check in Login.aspx.cs and put your auth in Page_Load() or Page_Init() event of Login.aspx.cs- wherever you want to perform some custom logging check- and then immediately redirect auth'd user to their requested URI.
I'm quite new to Unity and facing some problems about RESTFul in Unity.
I want to update some data on the server by using HTTP PUT, but as what I received when search the web, the WWWW class in Unity doesn't support HTTP PUT. I also tried some HttpWebRequest example related to HTTP PUT but always received error code 400: Bad Request.
How can I solve this problem?
Do I have to list out all the key-value pairs when updating or just need to list the pairs I want to change the value ?
If you're not looking for a 3rd party plugin and assuming your server supports it then one method you could look at using is the "X-HTTP-Method-Override" HTTP header. Your client sends the data to the server via POST, but the server handles this as the value in the X-HTTP-Method-Override header (such as PUT).
I've used this before to great effect where our server supported it. An example of using this in Unity3d would be along the lines of:
string url = "http://yourserver.com/endpoint";
byte[] body = Encoding.UTF8.GetBytes(json);
Dictionary<string, string> headers = new Dictionary<string, string>();
headers.Add( "Content-Type", "application/json" );
headers.Add( "X-HTTP-Method-Override", "PUT" );
WWW www = new WWW(url, body, headers);
I recommend looking at BestHTTP package instead of default WWW class. It's cheap (almost all Unity3d assets are, compared to typical middleware prices in game industry) and it's pretty decent, judging by personal experience.
Alternatively, you can use standard .NET sockets.
I made it worked by the following codes using HttpWebRequest
void updatePlayer(){
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://yourAPIUrl");
httpWebRequest.ContentType = "text/json";
httpWebRequest.Method = "PUT";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = "{" +
"'ID': '100'," +
"'ClubName': 'DEF'," +
"'Number': 102," +
"'Name': 'AnNT'," +
"'Position': 'GK'," +
"'DateOfBirth': '2010-06-15T00:00:00'," +
"'PlaceOfBirth': 'Hanoi'," +
"'Weight': 55," +
"'Height': 1.55," +
"'Description': 'des'," +
"'ImageLink': 'annt.png'," +
"'Status': false," +
"'Age': '12'" +
"}";
streamWriter.Write(json);
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var responseText = streamReader.ReadToEnd();
//Now you have your response.
//or false depending on information in the response
Debug.Log(responseText);
}
}
Do I need to install ASP.NET Web API Client Libraries (as this article indicates) in order to post data to a Web API server? If so, can I do so in Visual Studio 2008 from a Windows CE project?
The reasons I wonder are:
0) The client is a Windows CE project, for which I'm using Visual Studio 2008, and I don't know if ASP.NET Web API Client Libraries are available for that version; I know I don't have the NuGet Package Manager in that environment.
1) I am successfully querying data from my RESTful Web API methods without installing ASP.NET Web API Client Libraries, using code like this:
while (true)
{
deptList.departments.Clear();
string uri = String.Format("http://platypi:28642/api/Duckbills/{0}/{1}", lastIdFetched, RECORDS_TO_FETCH);
var webRequest = (HttpWebRequest) WebRequest.Create(uri);
webRequest.Method = "GET";
using (var webResponse = (HttpWebResponse)webRequest.GetResponse())
{
if (webResponse.StatusCode == HttpStatusCode.OK)
{
var reader = new StreamReader(webResponse.GetResponseStream());
string jsonizedDuckbills = reader.ReadToEnd();
List<Duckbill> duckbills = JsonConvert.DeserializeObject<List<Duckbill>>(jsonizedDuckbills);
if (duckbills.Count <= 0) break;
foreach (Duckbill duckbill in duckbills)
{
duckbillList.duckbills.Add(duckbill);
lastIdFetched = duckbill.Id;
}
} // if ((webResponse.StatusCode == HttpStatusCode.OK)
} // using HttpWebResponse
int recordsAdded = LocalDBUtils.BulkInsertDuckbills(duckbillList.duckbills);
totalRecordsAdded += recordsAdded;
} // while (true);
I'm stuck on posting, though, and the cleanest example I've seen so far for doing so is at that link already shown above.
I got an answer to my question on how to post here, but that hasn't made me smart enough yet to actually accomplish it. It's a step in the right direction, perhaps, although I reckon, based on how my client query code looks, that the client posting code would be of similar "style" (like the previously referenced article here, and unlike the likewise previously referenced answer here).
UPDATE
If I'm already providing the data in the uri string itself, as I am, like this:
string uri = String.Format("http://shannon2:28642/api/Departments/{0}/{1}", onAccountOfWally, moniker);
...why would I need to also specify it in postData? Or could I set postData (if that's just a necessary step to get the length) to those values...something like:
postData = String.Format("{0}, {1}", onAccountOfWally, moniker);
?
To talk to ASP.NET Web API, you do not necessarily need the client library, although it makes the life easier. After all, one of the benefits of HTTP services is the platform reach. Literally you can use any library that gives you HTTP capabilities. So, using WebRequest, you can do something like this. I'm using JSON in the payload. You can use XML and application/www-form-urlencoded as well. Just that you need to format the request body accordingly. Also, for complex objects, you will be better off using JSON.NET unlike formatting the JSON manually.
var request = System.Net.WebRequest.Create("http://localhost:12345/api/values");
request.Method = "POST";
string postData = "{\"firstName\":\"Steven\"," + "\"lastName\":\"Waugh\"}";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
request.ContentType = "application/json";
request.ContentLength = byteArray.Length;
using (var requestStream = request.GetRequestStream())
{
requestStream.Write(byteArray, 0, byteArray.Length);
}
using (var response = request.GetResponse())
{
using (var responseStream = response.GetResponseStream())
{
using (var reader = new System.IO.StreamReader(responseStream))
{
string responseFromServer = reader.ReadToEnd();
Console.WriteLine(responseFromServer);
}
}
}
EDIT
If you are specifying data in URI, you do not need to specify the same in the request body. To let web API bind the parameters for you from URI, you will need to specify the route accordingly so that the placeholders are set for onAccountOfWally and moniker. Then you will need to use a simple type like string as action method parameters for web API to bind. By default, simple types are bound from URI path and query string and complex types from request body.
