I m 试图利用Facebook图表普朗,从公共网页获得最新地位,请说。

http://developers.facebook.com/tools/explorer/?method=GET&path=microsoft%2Fstatuses”rel=“noreferer” http://developers.facebook.com/tools/explorer/?method=GET&path=microsoft%2Fstatuses。 - 我需要打字。由于微软网页是公开的,这无疑是这种情况吗? 难道我没有办法获得这些公共地位,没有机会得到证明?

如果是这样,那么如何为我的网站打造出入通道的正确方法? 然而,我有一份申请索引,但所有实例见:。描述处理用户标识。我只想获得微软网页的最新状况,并在我的网站上展示。

Answer 1

This is by design. Once it was possible to fetch the latest status from a public page without access token. That was changed in order to block unidentified anonymous access to the API. You can get an access token for the application (if you don t have a Facebook application set for your website - you should create it) with the following call using graph API:

https://graph.facebook.com/oauth/access_token?
client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&
grant_type=client_credentials

这称为App Access Token。然后,你使用从上述照相机进行实际的APIC电话。

希望这一帮助

Answer 2

You can use AppID and Secret key to get the public posts/feed of any page. This way you don t need to get the access-token. Call it like below.

https://graph.facebook.com/PAGE-ID/feed?access_token=APP-ID|APP-SECRET

并且获得职位。

https://graph.facebook.com/PAGE-ID/posts?access_token=APP-ID|APP-SECRET

Answer 3

It s no more possible to use Facebook Graph API without access token for reading public page statuses, what is called Page Public Content Access in Facebook API permissions. Access token even is not enough. You have to use appsecret_proof along with the access token in order to validate that you are the legitimate user. https://developers.facebook.com/blog/post/v2/2018/12/10/verification-for-individual-developers/. If you are individual developer, you have access to three pages of the data (limited), unless you own a business app.

You can get the posts by simply requesting the site that your browser would request and then extracting the posts from the HTML.

在NodeJS,你可以这样做:

// npm i request cheerio request-promise-native
const rp = require( request-promise-native ); // requires installation of `request`
const cheerio = require( cheerio );

function GetFbPosts(pageUrl) {
    const requestOptions = {
        url: pageUrl,
        headers: {
             User-Agent :  Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:64.0) Gecko/20100101 Firefox/64.0 
        }
    };
    return rp.get(requestOptions).then( postsHtml => {
        const $ = cheerio.load(postsHtml);
        const timeLinePostEls = $( .userContent ).map((i,el)=>$(el)).get();
        const posts = timeLinePostEls.map(post=>{
            return {
                message: post.html(),
                created_at: post.parents( .userContentWrapper ).find( .timestampContent ).html()
            }
        });
        return posts;
    });
}
GetFbPosts( https://www.facebook.com/pg/officialstackoverflow/posts/ ).then(posts=>{
    // Log all posts
    for (const post of posts) {
        console.log(post.created_at, post.message);
    }
});

我在数周内有类似的使用案例,我使用了该软件。

I could fetch all posts and comments in some minutes, worked quite well for me.
