Chrome扩展程序中的chrome.identity用户身份验证

问题描述

我试图编写一个需要用户身份验证的Chrome扩展。

I'm trying to write a chrome extension that requires user authentication.
Google's tutorial suggests that I need to upload to the web store first to get a key:

I uploaded a non-functioning version to just get the key, but it's hanging there pending for over a week now. How could I get that key or somehow inspire Google to approve this app that I don't want on the Web Store? Am I doing this all wrong?

You don't have to upload an extension to the Chrome Web Store in order to use the chrome.identity API. It suffices to have a valid extension ID. The easiest way to get started is to copy the 32-character extension ID from chrome://extensions/ to your project's credentials section at the API console .
Though if you ever want to publish the extension or use it in a different profile or computer, then you'd better choose an extension ID that you control. This can be done by setting the "key" key in the manifest file. See Obtaining Chrome Extension ID for development for a detailed answer on generating these keys.

For example, try out the following extension, using a key that I just generated. It will print your user info in a dialog.

manifest.json

{
    "key": "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA0W0/YVPvLrj2cWBOXfPBBYwPp56R+OJb9QLudyMpigF+V4DFV0NEUnbo9iA6m+7cVPiD6YbhbIaiAoHSdtqEKwaYvrEJRGuGsLjDq+RMwG2x+FcGIsO4ny0BuZaZ/Q2+DaL33NBUl2h9dIi1xa0Suq6qpoJ4yykTu9y7Q6rB9ulJze6DiZL7LWU5NzHCEWt21zAhpLZOqvYY8wzY69pMf+P0+uOLuy87x84rvCRNegbSmEYLC5f4y6ikjVnFUxJBxMlpMg3bByxbrLVBFPuHj4khkr6adUXgks2vBBHFcrRh5EYXopI+PLwUJPfFtzyN8+L7swen9kcK8gXMwX28KwIDAQAB",

    },

        "identity"
    ],

        "scopes": ["profile"]
    }
}

background.js

chrome.identity.getAuthToken({
    interactive: true
}, function(token) {
    if (chrome.runtime.lastError) {
        alert(chrome.runtime.lastError.message);
        return;
    }
    var x = new XMLHttpRequest();
    x.open('GET', 'https://www.googleapis.com/oauth2/v2/userinfo?alt=json&access_token=' + token);
    x.onload = function() {
        alert(x.response);
    };
    x.send();
});
