Cannot get json from the server

[mark goldin]

Here is my request:

Key Value

Request POST /services/reports_ws.asmx/getData HTTP/1.1

Accept application/json, text/plain, */*

Content-Type plain/text

I am getting the result as an xml while the server returns json string. I would specify Content-Type json but then my call simply fails.

Please help.

Thanks

Forgot to say I am doing cross domain.

Is there an angular JS question in here somewhere?

Open dev tools in your browser and check the payload you are receiving from the server. If you're expecting JSON, and receiving XML, then you server is broken, or your expectations are wrong ;)

It is an Angular question. My server returns json.

Sorry, I still don't understand the issue. You are trying to get JSON, and your server is returning JSON?
Maybe I'm dumb but can you explain in another way, or provide a plnker perhaps? http://plnkr.co/edit/rQvx8CXtmkCKR89jWn8T

Maybe you need to convert your response payload into a json object instead of a string?
JSON.parse(serverResponsePayload)

[mark goldin]

Here is what the server returns:

<string xmlns="something here/">{"assets":44,"projects":382}</string>

My server code is this:

[WebMethod(EnableSession = true)]

    virtual public string getCurrentSummaryWeb()

    {

        string json = JsonConvert.SerializeObject(getCurrentSummary());

        return json;

    }

The server is not returning Json; it's returning Xml. You need to change the method's expected and return format to Xml, e.g. maybe the URL should be like http://asdf/resource.json. The fact that then inner data is Json is misleading.

See this Rails example - http://edgeapi.rubyonrails.org/classes/ActionController/Responder.html

The web server needs to know about request formats and have separate responders for these formats.

I checked my server. Under MIME type I do see .json. Is that what you meant?

[Thomas Fee]

Tell me this: Suppose you make one request, in which you ask for JSON. Then a second request, in which you ask for XML. How do the two requests differ? Does the server respond differently?

[mark goldin]

I think that would be based on content-type?

<Does the server respond differently?

Dont have a tinniest idea.

[Thomas Fee]

I think the requested content type is supposed to only be a suggestion. I think the requested format must be more securely specified than that, e.g. .../posts.xml versus .../posts.json versus .../posts.html -- I think your web server needs some investigation.

Dont understand your last message. Are you saying I need to send a parameter to tell my code to return json? It's doing it already, it's somewhere on way back to the client it's changed into xml. I think.

[Thomas Fee]

It was just a discussion of the various options for distinguishing result format. Your web server may be using a method other than an Accept header. And btw, I was wrong about the header being only a suggestion.

BTW, that server code you showed didn't look right to my eyes. It isn't doing a "case" on the requested type and sending back different type depending on the request, i.e. I expect to see code that looks like this: http://stackoverflow.com/questions/2566759/how-can-i-generate-json-from-respond-to-method-in-rails

Here is what helped.

1. Mark web service as [ScriptService]

2. Mark method as [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
