Navigating string primitives when using AngularJS and $http: Tips and Tricks

A function in ASP.NET Web Api is returning a simple string as JSON data.

However, when calling this function from AngularJS, the returned value is surrounded by quotes instead of being a plain string:

return $http.post('/api/orders', data).then(function (results) {
        return result.data;

The value of result.data appears as "my string", enclosed in quotes. This is because the response is a string primitive and not an object. What is the recommended approach to handle this issue? Should we remove the quotes using a JavaScript function? Or should we modify the server to return an object instead of a primitive? Are there any specific configurations that need to be tweaked?

UPDATE:

The server utilizes a Web Api controller that directly returns a string:

 public IHttpActionResult SaveOrder() {return Ok("this is a test");}

This has the same effect as:

 public string  SaveOrder() {return "this is a test";}

The problem here is that the JSON value returned is not structured as an object; it's simply the raw string primitive.

Answer №1

Encountered a similar issue before. The problem arises when the controller returns a string. The method probably looks something like this:

public string ControllerAction(..) {...}

Instead of returning a string, you should return a HttpResponseMessage with the following structure:

public HttpResponseMessage ControllerAction() 
{
    var myContent = "my content";
    return new HttpResponseMessage()
    {
        Content = new StringContent(myContent, Encoding.UTF8, "text/html")
    };
}
