问题

We have mobilefirst adapter its working properly in swagger tool but when we are trying to invoke from client side its giving error for unsupported media type-errorcode 415.Environment mobilefirst 8.0 with ibm cloud object storage .

server side java adapter code below like that,
    -----------------------------------------
    @POST
    @Path("/uploadImageToObjectStorage")
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    @OAuthSecurity(enabled = false)
    public String uploadImage(@QueryParam(value="imageName") String imageNameWithExtn, @QueryParam(value="imageMimeType") String imageMimeType, @FormParam(value="imageDataInBase64Str") String imageBase64String){

    /// do to


    }

    cordova ionic 2 calling adapter or invoke adapter like that,
    -------------------------------------------------------------
    var resourceRequest = new WLResourceRequest("/adapters/Test/TestAdp/upload",WLResourceRequest.POST);
     resourceRequest.send().then((response) => {
        resourceRequest.setQueryParameter("imageName", 'store');
        resourceRequest.setQueryParameter("imageMimeType",'image/png'); 
        resourceRequest.setQueryParameter("imageDataInBase64Str",this.imageDataInBase64Str);  
        },
    function(error){
        console.log(error);
    });

回答1:

You should set the Content-Type of your resourceRequest to application/ x-www-form-urlencoded.

回答2:

Add this line in your code

resourceRequest.setHeader('Content-Type','application/x-www-form urlencoded');

I was implementing the device token adapter using IBM Work light and i got same error :

unsupported media (45) type error

when i used this :

request?.setHeaderValue("application/json" as NSObject, forName: "Content-Type")

Resolved my issue , try this.
