I have a Web API service that I'm trying to access via the console using RestSharp. My RestSharp code looks like this:
RestClient client = new RestClient(baseUrlString);
RestRequest request = new RestRequest("controllername/actionname");
request.RequestFormat = DataFormat.Json;
ProcessQuestion model = new ProcessQuestion()
{
Id = "123456",
InstanceId = "123",
UniqueId = "bfb16a18-d0d6-46ab-a5b3-2f0ebbfe8626",
PostedAnswer = new Dictionary<string, string>() { { "question_7907_1", "selected" }, { "question_7907_2", "selected" } }
};
request.AddBody(model);
var response = client.Execute(request)
My Web API action takes a model that has the same parameters as the above model. When the call executes, the binding fails and the parameter is null. I suspect this is due to the RestRequest.AddBody method prepending application/json to the body value as shown below:
{application/json={"Id":"123456","InstanceId":"123","UniqueId":"bfb16a18-d0d6-46ab-a5b3-2f0ebbfe8626","PostedAnswer":{"question_7907_1":"selected","question_7907_2":"selected"}}}
If I post using Fiddler the body binds to the model properly. Below is the body value I provided in Fiddler:
{'Id':'123456','InstanceId':'123','Uniqueid':'bfb16a18-d0d6-46ab-a5b3-2f0ebbfe8626','PostedAnswer':{'question_7907_1':'selected','question_7907_2':'selected'}}
Note that the body value in fiddler is the same with the exception of prepending the application/json key.
Also to note: I've tried what seems like everything...I've separated the parameters out in the action, used FromBody and FromUri attributes, tried custom DictionaryModelBinder's, tried custom ValueBinders, tried changing the way I'm using RestSharp (AddParameter with a RequestBody parameter, AddObject, different URL styles, etc.).
Has anyone else encountered this, and if so, did you solve it? I chose Web API for this service with hopes the model binding would work as it does in MVC, but I'm seeing that isn't the case.
Thanks
EDIT (resolved):
RestSharp automatically uses the JsonSerializer for objects passed in the AddBody method. I figured I was missing something simple, and indeed I was... Adding the Method.Post parameter to the RestRequest instantiation solved the problem.
Specify the method when creating the request:
RestRequest request = new RestRequest("controllername/actionname", Method.POST);
Not sure what the default serializer is for body - you can try making it explicit:
request.AddBody(request.JsonSerializer.Serialize(model));
I'm not sure where the 'application/json' is coming from - that's the Content-Type header you should be sending with your request, definitely not part of the body. So do this instead:
request.AddHeader("Content-type", "application/json; charset=utf-8");
If this doesn't help, try making your code as similar to the example on their site as possible. Try removing complexity (even if it means changing the required functionality) - get it to a point when it works and build additional functionality on that.

I'm new to AWS AppSync and I am trying to access certain body property(from HTTP response) in my resolver's response mapping template.
For example: I am able to present the response as is via $util.toJson($ctx.result.body), but when I try to get some of the nested body properties it fails.
For example, imagine the body looks like this:
{
about:{
"firstName":"Chuck",
"lastName":"Norris"
}
}
and $util.toJson($ctx.result.body.about) returns null. Any thoughts?
I found a way extract the parsed body in the following way:
#set ($parsed_body = $util.parseJson($ctx.result.body))
And then I am able to access the properties via dot notation:
parsed_body.about.firstName
The part I was missing is $util.parseJson(<json-string>)
It seems that the body is a JSON string.
I am using SOAP UI 5.7.0 to mock a REST service and it is working fine. Only, when I want to access the body of a POST request with mockRequest.requestContent, the correct content is returned only in the first call, but from then on, it always returns the empty string.
I tried the call in OnRequestScript and in the POST requests own Dispatch script but the behavior is the same in both cases. I have the suspicion, that the Stream of the request is already read somewhere else and so does not return any more content. But I don't know what to do about it.
I wonder what is the correct way to read the content of a POST request.
Thank you
Appears to be a known issue, see posts in the community forum here and here.
this seems to be an old bug of PUT operation in REST mocks.
Unfortunately, this is a bug. There is an internal defect of SOAP-2344 for this issue. This applies for the PUT and DELETE methods for a REST mock service.
I have the same issue with a PATCH request.
Use the following trick to get the body of the PUT and DELETE requests:
mockRequest.with {
if (method.toString() == 'PUT' || method.toString() == 'DELETE') {
InputStreamReader isr = new InputStreamReader(request.getInputStream(), "UTF-8")
BufferedReader br = new BufferedReader(isr)
StringBuilder sb = new StringBuilder()
while ((s=br.readLine())!=null) {
sb.append(s)
}
def requestBody = new groovy.json.JsonSlurper().parseText(sb.toString())
log.info "requestBody: " + requestBody
}
}
I use it on the project but I don't really remember how where I got the snippet from. I had to change some parts to make it work as far as I remember. Give it a try.
I have a class that models exactly the entity I have in the database. I have a stored procedure that takes in parameters for a new row and returns all the settings in the table which in turn populates my repository. I am able to see the results of GET, PUT and DELETE in the List of type Setting that is in memory. I am noticing first that even when I close Visual Studio and reopen and run the project, sometimes, the List is still in the state it was before. It is not repopulating from the database so I'm not sure why that is first of all... Secondly, I can't seem to get POST to work from Fiddler unlike the other HTTP verbs. I DO see the values from Fiddler show up in the code below but I get the error: Invalid URI: The format of the URI could not be determined. I get the same error if I pass an ID or not.
Here is what I put into Fiddler:
POST localhost:54852/api/settings
Request Headers
User-Agent: Fiddler
Content-type: application/x-www-form-urlencoded
Host: localhost:54852
Content-Length: 149
Request Body
ID=0&Category=Dried%20Goods&Sub_Category=Other&UnitSize=99&UnitOfMeasureID=999&Facings=true&Quantity=true&EverydayPrice=999.99&PromotionPrice=111.11
PostSetting function within my SettingsController
public HttpResponseMessage PostSetting(Setting item)
{
item = repository.Add(item);
var response = new HttpResponseMessage<Setting>(item) { StatusCode = HttpStatusCode.Created };
string uri = Url.Route("DefaultApi", new { id = item.ID });
response.Headers.Location = new Uri(uri);
return response;
}
Should I create a new procedure that gets the MAXID from the database and use that as the NEW ID in the line above where a new ID is created?
You need to create a JSON representation of the Setting class or item that you are wanting to test with use Fiddler (now a Telerik product) and use the Composer tab.
Next you will want to perform a POST to the following URL:
http://[your base url]/api/settings
and pass the JSON formatted setting class.
You can see an example of this here: ASP.NET Web API - Scott Hanselman
Here is a short video showing how to achieve it easily
get and post to webapi from fiddler
Recently I was using RestSharp to consume my Restful Resouce. and expected exchanging data with JSon between server and client. Below is my C# code.
var client = new RestSharp.RestClient();
var request = new RestRequest(sUrl,Method.POST);
request.RequestFormat = DataFormat.Json;
request.Timeout = TIME_OUT_MILLISECONTS ;
request.AddHeader("Content-Type", "application/json");
request.AddBody(new { appID = sAppId, loginName = sUserName, password=sPassword });
var response = client.Execute(request);
string s=response.Content;//It is always XML format.
The result is not what I expected for(Json data format), although I had set the RequestFormat Json and add Http header Content-Type. So I decided to use the .Net Reflector to found out What happened in the RestClient.Execute method. Here is the code of the method.
public RestClient()
{
...
this.AddHandler("application/json", new JsonDeserializer());
this.AddHandler("application/xml", new XmlDeserializer());
this.AddHandler("text/json", new JsonDeserializer());
this.AddHandler("text/x-json", new JsonDeserializer());
this.AddHandler("text/javascript", new JsonDeserializer());
this.AddHandler("text/xml", new XmlDeserializer());
this.AddHandler("*", new XmlDeserializer());
...
}
I have some questions about it:
As the RestClient adds many kinds of Content-Type into the HttpWebRequest. Is it right way to build a Request? And I think Maybe that is the reason why Response.Content always XML.
I don't know why the RestClient needs to build a HttpWebRequest like that. Any meaning to do that?
If we specified both JSon and XMl message format in a Http Request, which one works finally? Is it allowed?
Thanks. Have a good day.
RestSharp will use the correct handler based on the content type of the response. That's what those AddHandlers are doing; its configuring the RestClient to accept certain content types in the response and mapping those types to deserializers. Normally you would want to set an accept header for the json content type which notifies the server to send json in the response.
request.AddHeader("Accept", "application/json")
Of course, this assumes that the server you are hitting is configured to respond with json.
I am developing a new REST-full webservice for our application,I wanted to send the reqest data in requestHeader instead of sending as query param, as my request data is large.
I have My jquery code like below to add json to the request header and call the REST service GET method.
$.ajax({
beforeSend: function(req) {
req.setRequestHeader("test", "{name:mouli, id:918}");},
type : "GET",
data :'',
dataType : "jsonp",
url : 'http://localhost:29801/RestFulJSONExample/rest/jobdesc?callback=?',
success : function(data) {
alert("invoked");
}
});
});
And my GET method in my REST service is like
#GET
#Produces("application/javascript")
public JSONWithPadding getJobDescription(#Context HttpHeaders headers) {
List<String> requestHeader = headers.getRequestHeader("test");
//some logic here.
}
i could able to get the JSON object from the request header which i have added in the jquery request.
My question is ..
Can i follow this approach? is it secure and safe?
If not please tell me the other way?
What appears at the right side of the ":" in a header is mostly free. You have to take into account character set restriction in HTTP, and possible carriage returns in the JSON value (you know, headers of more than one line have a specific syntax). If your JSON examples are relatively simple, then I see no problem in that. It is just another way of organizing the actual value of a header line.
