I have a Grails controller that receives a DefaultMultipartHttpServletRequest like so:
def myController() {
DefaultMultipartHttpServletRequest proxyRequest = (DefaultMultipartHttpServletRequest) request
}
This controller acts as a proxy by taking pieces of this request and then resends the request to another destination.
For non-multipart requests, this worked fine, I did something like:
IProxyService service = (IProxyService) clientFactory.create()
Response response = service.doPOST(proxyRequest.getRequestBody())
Where proxyRequest.getRequestBody() contains a JSON block containing the request payload.
However, I do not know how to get this to work with multipart request payload, since the request body is no longer a simple block of JSON, but something like the following (taken from Chrome devtools):
How can I can pass this request payload through using my proxy service above, where doPost takes a String?
Have you tried
def parameterValue = request.getParameter("parameterName")
to get the parameter value?
If you see the method signatures for DefaultMultipartHttpServletRequest you will see there are methods for getting the files and other parameters separately because the request body is getting used to both upload the file and to pass in other parameters.

I can not figure out what I'm doing wrong. I'm developing an App for BigCommerce and can not get the simple oAuth exchange to work correctly.
The initial get request is being made to https://www.my-app.com/oauth/bigcommerce/auth. This is the code in the controller for that request. It's a Laravel 5.6 app:
use Illuminate\Http\Request;
use Bigcommerce\Api\Client as Bigcommerce;
class BigcommerceOAuthController extends Controller
{
public function auth(Request $request)
{
$object = new \stdClass();
$object->client_id = 'my-client-id';
$object->client_secret = 'my-client-secret';
$object->redirect_uri = 'https://my-app.com/oauth/bigcommerce/auth';
$object->code = $request->get('code');
$object->context = $request->get('context');
$object->scope = $request->get('scope');
$authTokenResponse = Bigcommerce::getAuthToken($object);
$storeHash = str_replace('stores/', '', $request->get('context'));
Bigcommerce::configure(array(
'client_id' => 'my-client-id',
'auth_token' => $authTokenResponse->access_token,
'store_hash' => $storeHash
));
echo "<pre>";
print_r($authTokenResponse);
print_r(Bigcommerce::getTime());
echo "</pre>";
}
}
Every time I try to install my draft app from the BigCommerce control panel, I get an error because $authTokenResponse is not an object. When I debug further into the Bigcommerce\Api\Connection class, I can see that the response from the server is empty, and the status is a 401, which means "Unauthorized".
I can't figure out why I am getting this error. As far as I can see, I'm doing everything right. I've tried urlencoding the string retrieved from $request->get('scope'), since that string becomes unencoded by Laravel, but that didn't seem to help.
I am also confused how this is even supposed to work at all. In the BigCommerce docs, they show this example POST request, which uses application/x-www-form-urlencoded Content-Type and passes the request body as a url encoded string:
POST /oauth2/token HTTP/1.1 Host: login.bigcommerce.com Content-Type:
application/x-www-form-urlencoded Content-Length: 186
client_id={CLIENT_ID}&client_secret={CLIENT_SECRET}&code=qr6h3thvbvag2ffq&scope=store_v2_orders&grant_type=authorization_code&redirect_uri=https://app.example.com/oauth&context=stores/{STORE_HASH}
However, if you inspect what's going on in the Connection class, you can see that the Content-Type is being set to application/x-www-form-urlencoded as the docs say, but the request body is being passed in as a json string, not a url string. Shouldn't the request be a url encoded string as the docs suggest?
A couple of things here to check:
Do you have a public URL where you can receive the Auth Callback?
If so, did the store owner registered the app successfully? https://developer.bigcommerce.com/api/registration
When you have the client_id and secret_id. You should have all of the details needed to send a POST request to the BC Auth Token Service at https://login.bigcommerce.com/oauth2/token
The content uses URL encode Make sure to URL encode your content. Be careful of of the encoding of & and = signs when those are actually being used as separators.

HI I have been trying to call REST POST API using jersey REST Client. The API is docs is
URL:
METHOD: POST
Header Info:-
X-GWS-APP-NAME: XYZ
Accept: application/json or application/xml
My Sample Jersey client code is
Client client = Client.create();
WebResource resource=client.resource(URL);
resource.accept(javax.ws.rs.core.MediaType.APPLICATION_XML);
resource.type(javax.ws.rs.core.MediaType.APPLICATION_XML);
resource.type("charset=utf-8");
ClientResponse response = resource.post(ClientResponse.class,myReqObj);
I have been trying this code variation since last 1 week and it is not working. Any help in this regard is highly appreciated.
The tricky part is that the WebResource methods follows the Builder design pattern so it returns a Builder object which you need to preserve and carry on as you call further methods to set the full context of the request.
When you do resource.accept, it returns something you don't store, so it's lost when you do resource.type and therefore only your last call takes effect.
You'd typically set all the criterias in one line, but you could also save the output in a local variable.
ClientResponse response = client.resource(URL)
.accept(MediaType.APPLICATION_XML)
.type(MediaType.APPLICATION_XML)
.post(ClientResponse.class,myReqObj);
I do like that.
Response response = webTarget.request(MediaType.APPLICATION_JSON_TYPE)
.accept(MediaType.APPLICATION_JSON_TYPE)
.post(Entity.entity(a, "application/json; charset=UTF-8"));
here, 'a' is account class instance which like
#XmlRootElement
public class account {
...
...
}
How do I invoke a Service Operation in WCF from iOS?
I have a Service Operation defined in my WCF Data Service (tied to a stored procedure in my DB schema) that I need to invoke from iOS. Say I've got the following declaration in my .svc.cs file:
[WebInvoke(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
public IQueryable<Foo> GetFoos(int param1, DateTime param2, string param3)
{
return CurrentDataSource.GetFoos(param1, param2, param3).AsQueryable();
}
And I've got it set up with the proper rights in InitializeService:
config.SetServiceOperationAccessRule("GetFoos", ServiceOperationRights.AllRead);
When I try to invoke this via HTTP POST from iOS, I get back an error wrapped in JSON:
Bad Request - Error in query syntax.
It seems like it doesn't like how I'm passing my parameters. I'm passing them JSON-encoded (using NSJSONSerialization to turn an NSDictionary into a JSON string) in the request body of a POST request. The same method works on another web service (.svc) not connected to WCF that has operations annotated the same way.
An answer to another question of mine in a similar vein suggests that data formats can be negotiated between client and server, and I've read that dates are a pain to format, so maybe it's my DateTime parameter that's a problem. But I've tried both the JSON format (\/Date(836438400000)\/ and /Date(836438400000)/) and the JSON Light format (1996-07-16T00:00:00) to no avail.
So my question is this: what is the proper way to invoke this operation? If I need to have my app tell the server what format to expect, how do I do that?
Update: I tried using the format datetime'1996-07-16T00:00:00' as mentioned in this question. Same error.
Update 2: The MSDN page for Service Operations seems to suggest that nothing besides Method = "POST" is supported when annotating the WebInvoke for a Service Operation. I tried removing everything from what is quoted in the above code and setting the method to POST. Same error.
Update 3: On Pawel's suggestion, I made a new Service Operation on my Data Service just like this:
[WebInvoke(Method = "POST")]
public IQueryable<string> GetFoos()
{
List<string> foos = new List<string>();
foos.Add("bar");
return foos.AsQueryable();
}
I was able to make it work in Fiddler's Composer pane by setting the method to POST, adding accept:application/json;charset=utf-8 and Content-Length:0 to the headers. Then I added a single int parameter to the operation (called param1). I set the body of my request in Fiddler to {"param1":"1"} and ran it (and Fiddler automatically updated my content-length header), and got the same error. I changed the type of my parameter to string and ran my request again and it worked. So my problem seems to be non-string types.
You need to send parameters in the Url and not in the request body.
I have this request that comes in like this:
Parameters: {"kpi"=>{"action"=>"create", "users"=>[{"las_name"=>"Doe", "user_id"=>"123", "first_name"=>"John"}, {"las_name"=>"Smith", "user_id"=>"456", "first_name"=>"Anna"}, {"user_id"=>"789", "last_name"=>"Jones", "first_name"=>"Peter"}], "controller"=>"api/kpis"}, "users"=>[{"las_name"=>"Doe", "user_id"=>"123", "first_name"=>"John"}, {"las_name"=>"Smith", "user_id"=>"456", "first_name"=>"Anna"}, {"user_id"=>"789", "last_name"=>"Jones", "first_name"=>"Peter"}]}
but it comes as JSON in a POST request so I am not sure how to get it into a local variable.
Any idea how to do that?
Thanks!
The fact that the parameters are showing up like that means that your create action is properly set up to handle JSON as a transport mechanism. Based on that snippet, you can access these parameters via the params hash.
kpi = params[:kpi]
#users = kpi["users"]
I am making a POST request with RestSharp (on windows phone 7.1 client). I sent string to a service in a request body. Looks like the service is successfully called and it returns proper value (integer), however response object is null:
client.ExecuteAsync<T>(request, (response) => {
data = response.Data; // response is null in debugger
});
I cant understand why is that so.
<T> isn't a valid value for that call. I'm not sure that would even build there unless you've wrapped it in a generic method.
Also, is the response coming back as plain text? What's the Content-Type returned? Most likely, you should just use ExecuteAsync(request, callback) without the generic parameter and grab the data out of response.Content which is a string of the response body. response.Data is for the automatically deserialized XML or JSON (or custom) response if you use the generic method overload that specifies a type to deserialize to.
This seems to be an ongoing issue with RestSharp asynchronous calls - for HTTP transport errors ErrorException object is useless (returns null). Check the StatusCode property if it returns with anything but HttpStatusCode.OK. StatusDescription is not extremely useful either as it doesn't match complete status message from server response payload.
