How do we log contents of JSON responses?

[tansongyang]

I tried turning on logContentsOfXhrCalls in our application. Request bodies get sent just fine, but response bodies are not.

The problem appears to be here. This guard checks if the responseType is empty string or 'text'. If so, the response text is included. Otherwise, we get the default text 'N/A for non text responses', which is what I'm seeing. And it's because I'm dealing with responseType === 'blob', specifically a JSON blob.

What is the guidance here?

Hi @tansongyang,

Thanks for reporting this issue. We have some updates planned to this library, so I'll investigate expanding the supported response types for logContentsOfXhrCalls as part of this work.

As it stands I don't think logging blob responses is currently possible with raygun4js. One workaround would be to add another wrapper to XMLHttpRequest to log these response bodies, following the same style as the raygun.network-tracking.js file linked.

@Widdershin Thanks for the quick response! Good to know about the workaround.
