将Javascript用于Dropbox核心API

Question

I am not a js programmer. But for some reason, I have to write a js program to get the access token so that the program can use the dropbox core api.

what I have tried is the following:

         var xhr = new XMLHttpRequest();
         xhr.open("POST", "https://api.dropbox.com/1/oauth/request_token?oauth_consumer_key=qxxxxxxxx&oauth_consumer_secret=axxxxxxxxx", false);
         xhr.send();
         console.log("status: " + xhr.statusText);
         console.log("response: " + xhr.responseText);

This is not work...I need help~

response: {"error": "Unauthorized"} this is the error message I received

Answer 1

The call to request_token has to be signed with OAuth. You should be passing an Authorization header that looks something like this (using a PLAINTEXT signature):

OAuth oauth_version="1.0", oauth_signature_method="PLAINTEXT", oauth_consumer_key="<app key>", oauth_signature="<app secret>&"

But, before you go down this path, you should really use OAuth 2 instead. It's simpler than OAuth 1. The only reason I can see to use OAuth 1 is if you're app can't be hosted on HTTPS. (OAuth 2 requires an HTTPS redirect URI.)

And, before you build that all by hand, you should just use dropbox-js . Then your code would be something like this:

var client = new Dropbox.Client({key: '<app secret>'});
client.authenticate();
