Web API Get Method with Complex Object as Parameter

Question

How to send a Complex Object( Which may have huge data) to a Web API Get Method? I know I can user \'FromUri\' option, but since the data is too large I can\'t use that opti

Answer 1

You need to create a method similar to the below:

[HttpPost]
public HttpResponseMessage MyMethod([FromBody] MyComplexObject body)
{
    try
    {
        // Do stuff with 'body'
        myService.Process(body);
    }
    catch (MyCustomException)
    {
        return new HttpResponseMessage(HttpStatusCode.BadRequest) { Content = new StringContent("FAILED") };
    }

    return new HttpResponseMessage(HttpStatusCode.OK) { Content = new StringContent("OK") };
}

If your POSTing data larger than 4MB, then you'll need to adjust your web.config to configure IIS to accept more, the below example sets the maxRequestLength and maxAllowedContentLength to 10MB:
