REST Hammock not adding content to post body - rest

I've been fiddling a POST request that isn't working. What I've found is that the content of the request is empty even though I believe I'm adding it correctly (even though there aren't any docs available that I can find).
var json = JsonConvert.SerializeObject(payload);
var client = new RestClient
{
Authority = "",
Credentials = OAuthCredentials.ForProtectedResource(Registration.ClientKey,
Registration.ClientSecret,
AuthorizationToken.Token,
AuthorizationToken.Secret),
Method = WebMethod.Post,
Path = url
};
var request = new RestRequest();
request.AddHeader("Accept", ContentType);
request.AddHeader("Content-Type", ContentType);
request.AddPostContent(Encoding.UTF8.GetBytes(json));
response = client.Request(request);
I'm not having any trouble with authorization. I just kept getting a 400 error. After capturing the request with Fiddler, I noticed that content-length was 0. What am I missing? Do I need to do something in addition to AddPostContent? When I check the request object right before executing, there is content in PostContent, but it's as if Hammock isn't adding it to the request. I am using the latest full nuget (not ClientProfile).

Calling API from Saleforce is giving error code 500

I have a REST API to callout from Salesforce.
The authorization of the API is through access token.
I am able to get the access token through POST request in Salesforce. Also tested from Postman through that token and able to get a successful response.
I am using the below code to callout the API using the access token:
String endpoint_x = '*****';//Putting my endpoint here
Http httpObject;
HttpResponse response;
String accessToken;
accessToken = MyUtilityClass.getAccessToken();
jsonBody = json.serializePretty('', true);//Yes, My JSON is empty
HttpRequest request = new HttpRequest();
request.setEndpoint(endpoint_x);
request.setHeader('Authorization', 'Bearer '+accessToken);
request.setMethod('POST');
request.setBody(jsonBody);
httpObject = new Http();
response = httpObject.send(request);
System.debug('Response=' + response);
Getting Response value as below:
System.HttpResponse[Status=Internal Server Error, StatusCode=500]
I have tried putting '{}' in the Jsonbody. Added 'Content-Type' in header but nothing worked.
Where should I lookout for this?
In the Postman, I was not putting anything in the body, and getting a successful response.
To get the same behaviour, I was using empty string in Apex, like this:
jsonBody = json.serializePretty('', true);
But the parser was not working correctly.
To solve this, I created a class without any field:
class ClassForEmptyBody{
}
And used object of that class in the serializer:
ClassForEmptyBody classForEmptyBodyObject = new ClassForEmptyBody();
jsonBody = json.serializePretty(classForEmptyBodyObject , true);
Why are you passing json body if nothing is in there. Just skip setbody code and try.

StreamReader reads \u00fc but Postman reads OK

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!

Add flag to UnityWebRequest

I am trying to make a POST request to webpage that expects the --data field to be filled with some data to be processed. I'm pretty much trying to recreate this curl request, but with UnityWebRequest.
curl -X POST http://localhost:8000/clic/say?text=Make+the+gene+set --data '{"geneSetMembers":["UST"],"geneSetName":"selection0"}'
The UnityWebRequest documentation mentions that GET requests don't set any flags other than the url, but it's not clear if no other custom options exist for posts. Is there some way to format a WWWform or something that will hold the data such that the server will recognize it?
var form = new WWWForm();
// some way to plug in the jsonified data to the form
webRequest = UnityWebRequest.Post(url + route + to_say, form);
webRequest.downloadHandler = new DownloadHandlerBuffer();
webRequest.SetRequestHeader("Content-Type", "application/json");
webRequest.SendWebRequest();
// etc etc
I've tried just giving the form a field named "data" a la
form.AddField("data", "{ \"geneSetMembers\":[\"UST\"],\"geneSetName\":\"selection0\"}");
but the server does not like it, saying it "got error Invalid JSON literal name: data" So clearly that's the wrong syntax for it
EDIT: put lines in the same order they were in original code. Sorry, I have commented lines between them
Maybe your server doesn't like to receive the data as a field called data.
This ofcourse depends totally on the PHP code we don't see since you didn't share that part. b
But at least I can tell you that --data or also simply -d in curl refer to the entire data section and is not a field called data.
You could try to instead use a MultiPartFormDataSection passing just the data itself without a specific field name
var data = "{\"geneSetMembers\":[\"UST\"],\"geneSetName\":\"selection0\"}";
var form = new List<IMultiFormPart>{ new MultiPartFormDataSection(data) };
webRequest = UnityWebRequest.Post(url + route + to_say, form);
yield return webRequest.SendWebRequest();
which is now sent as content-type multipart/form-data though ...
Another alternative if your server really needs to receive a content-type application/json might be to "manually" compose the request e.g. like
var data = "{\"geneSetMembers\":[\"UST\"],\"geneSetName\":\"selection0\"}";
var request = new UnityWebRequest(url + route + to_say, "POST");
var bodyRaw = Encoding.UTF8.GetBytes(data);
request.uploadHandler = (UploadHandler) new UploadHandlerRaw(bodyRaw);
request.downloadHandler = (DownloadHandler) new DownloadHandlerBuffer();
request.SetRequestHeader("Content-Type", "application/json");
yield return request.SendWebRequest();
Though of you look close now this seems actually not to be the case since if you read the man curl
(HTTP) Sends the specified data in a POST request to the HTTP server, in the same way that a browser does when a user has filled in an HTML form and presses the submit button. This will cause curl to pass the data to the server using the content-type application/x-www-form-urlencoded
which is actually exactly the default content type used by the simple string version of UnityWebRequest.Post.
So thinking about it it should actually be as simple as using the pure string version of UnityWebRequest.Post:
var data = "{\"geneSetMembers\":[\"UST\"],\"geneSetName\":\"selection0\"}";
var request = UnityWebRequest.Post(url + route + to_say, data);
yield return request.SendWebRequest();

How to call SSRS Rest-Api V1.0 with custom security implemented (NOT SOAP)

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.

Azure encoding job via REST Fails

I am trying to upload a video and encode it via azure rest service.
I have now hit the step of encoding the video but I am having difficulties with the request.
The following code shows my request:
var joburl = res.RequestMessage.RequestUri + "Jobs";
client = new HttpClient();
client.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", "Bearer " + token);
client.DefaultRequestHeaders.Add("x-ms-version", "2.8");
client.DefaultRequestHeaders.Add("DataServiceVersion", "3.0");
client.DefaultRequestHeaders.Add("MaxDataServiceVersion", "3.0");
client.DefaultRequestHeaders.Add("x-ms-date", date);
//accept
t = new NameValueHeaderValue("odata", "verbose");
type = new MediaTypeWithQualityHeaderValue("application/json");
type.Parameters.Add(t);
client.DefaultRequestHeaders.Accept.Add(type);
result = await client.PostAsync(joburl,json);
the url:https://wamsamsclus001rest-hs.cloudapp.net/api/Jobs
the json:
{"Name":"khgfiuydencodingjob","InputMediaAssets":[{"__metadata":{"Uri":"https://wamsamsclus001rest-hs.cloudapp.net/api/Assets('nb%3acid%3aUUID%3ad037b321-cd1c-43a9-9607-c4910fa7a85b')"}}],"Tasks":[{"Configuration":"H264 Adaptive Bitrate MP4 Set 720p","MediaProcessorId":"nb:mpid:UUID:1b1da727-93ae-4e46-a8a1-268828765609","TaskBody":"<?xml version=\"1.0\"encoding=\"utf-8\"?><taskBody><inputAsset>JobInputAsset(0)</inputAsset><outputAsset>JobOutputAsset(0)</outputAsset></taskBody>"}]}
The bearer token works as I use it for other request.
But I get a bad request 400 with the followin error message:
{"error":{"code":"","message":{"lang":"en-US","value":"Parsing request content failed due to: Make sure to only use property names that are defined by the type"}}}
Can anyone spot the error.
Thank you for the help
Okay I got it to work. Needed a odata=verbose in my json/string content - like this:
var jobInJson = JsonConvert.SerializeObject(job);
json = new StringContent(jobInJson, Encoding.UTF8);//,
json.Headers.ContentType = MediaTypeHeaderValue.Parse("application/json;odata=verbose");
I tried this earlier however I got a error 500 but now it is working.
