如何在Google Go中为QuickBooks API调用正确添加OAuth标头

问题描述：

I am just trying to get a proof of concept working to test a connection to the QB api for a QB Online account. I have never tried to make an OAuth connection before like this, so I'm not sure that I am doing it right. Here's what I have so far, and it makes the request but I get a 401 error returned from QB's server (Unauthorized OAuth Token: signature_invalid401SERVER):

client := &http.Client{}
if req, err := http.NewRequest("GET", "https://qbo.intuit.com/qbo1/resource/customers/v2/717594130", nil); err != nil {
    //handle error
} else {
    req.Header.Add("Authorization", "OAuth oauth_token=\"MY_TOKEN\",oauth_nonce=\"7758caa9-e1f4-4fa1-84c5-5759fd513a88\",oauth_consumer_key=\"MY_KEY\",oauth_signature_method=\"HMAC-SHA1\",oauth_timestamp=\"1369259523\",oauth_version=\"1.0\",oauth_signature=\"MY_SIG\"")
    if resp, err := client.Do(req); err != nil {
        //handle error
    } else {
        defer resp.Body.Close()
        contents, err := ioutil.ReadAll(resp.Body)
        if err != nil {
            //handle error
        }
        myOutput := string(contents)
    }
}

Could the problem may be with my settings on my QB account instead? There is a setting for "Host Name Domain" that I think it might only allow connections from what I have entered there (which is currently intuit.com). If that is the case, how do I set that to allow connections from my dev app on my localhost?

Are you using the correct OAuth algorithm to generate the signature?

Can you post an actual request/response that shows the outgoing signature/OAuth header, and the response you get back from Intuit?

Your code doesn't show any of that, and it doesn't look like you're using an Intuit DevKit, so that's probably the place to start. My guess would be that the signature you're sending isn't valid. I would highly recommend you find a OAuth library, and use that OAuth library, rather than try to roll your own OAuth algorithm.

As far as this goes:

That is not likely to be the problem... but to get any further than a simple test request, you will need to set that to your host name. If it's a local dev box, you can enter your local dev boxes hostname (e.g. http://localhost/ or http://192.168.1.2/ or anything like that is fine - whatever URL you use to hit your dev box)
