問題描述
事實(shí):我運(yùn)行一個(gè)簡單的網(wǎng)站，其中包含文章、通過抓取第三方網(wǎng)站/博客等動(dòng)態(tài)獲取的文章(新文章每半小時(shí)左右到達(dá)我的網(wǎng)站)、文章我想在我的 facebook 頁面上發(fā)帖.每篇文章通常包括一張圖片、一個(gè)標(biāo)題和一些文字.
Facts: I run a simple website that contains articles, articles dynamically acquired by scraping third-party websites/blogs etc (new articles arrive to my website every half an hour or so), articles which I wish to post on my facebook page. Each article typically includes an image, a title and some text.
問題:我在 Facebook 上發(fā)布的大部分(幾乎所有)文章都沒有正確發(fā)布 - 缺少圖片.
Problem: Most (almost all) of the articles that I post on Facebook are not posted correctly - their images are missing.
低效解決方案:使用 Facebook 的調(diào)試器(這個(gè))我向它提交了一篇文章的 URL(來自我網(wǎng)站的 URL，而不是原始來源的 URL)，然后 Facebook 掃描/抓取 URL 并正確提取所需的信息(圖像、標(biāo)題、文本等).執(zhí)行此操作后，文章可以正確發(fā)布到 Facebook 上 - 不會丟失圖片或任何內(nèi)容.
Inefficient Solution: Using Facebook's debugger (this one) I submit an article's URL to it (URL from my website, not the original source's URL) and Facebook then scans/scrapes the URL and correctly extracts the needed information (image, title, text etc). After this action, the article can be posted on Facebook correctly - no missing images or anything.
目標(biāo):我所追求的是一種創(chuàng)建過程的方法，該過程將向 Facebook 的調(diào)試器提交 URL，從而迫使 Facebook 掃描/抓取 URL，以便隨后可以正確發(fā)布.我相信我需要做的是創(chuàng)建一個(gè)包含 URL 的 HTML POST 請求并將其提交給 Facebook 的調(diào)試器.這是正確的方法嗎?如果是，因?yàn)槲乙郧皼]有使用 CURL 的經(jīng)驗(yàn)，那么在 PHP 中使用 CURL 的正確方法是什么?
Goal: What I am after is a way to create a process which will submit a URL to Facebook's debugger, thus forcing Facebook to scan/scrape the URL so that it can then be posted correctly. I believe that what I need to do is to create an HTML POST request containing the URL and submit it to Facebook's debugger. Is this the correct way to go? And if yes, as I have no previous experience with CURL, what is the correct way to do it using CURL in PHP?
旁注:作為旁注，我應(yīng)該提到我的文章使用的是短 URL，盡管我認(rèn)為這不是問題的原因，因?yàn)榧词乖谖沂褂靡?guī)范的 URL.
Side Notes: As a side note, I should mention that I am using short URLs for my articles, although I do not think that this is the cause of the problem because the problem persists even when I use the canonical URLs.
此外，Open Graph 元標(biāo)記設(shè)置正確(og:image、og:description 等).
Also, the Open Graph meta tags are correctly set (og:image, og:description, etc).
推薦答案
您可以使用帶有 PHP-cURL 的 Facebook 圖形 API 調(diào)試圖形對象，方法是執(zhí)行 POST
You can debug a graph object using Facebook graph API with PHP-cURL, by doing a POST to
https://graph.facebook.com/v1.0/?id={Object_URL}&scrape=1
為了更簡單，我們可以將調(diào)試器包裝在一個(gè)函數(shù)中:
to make thing easier, we can wrap our debugger within a function:
function facebookDebugger($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/v1.0/?id='. urlencode($url). '&scrape=1');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$r = curl_exec($ch);
return $r;
}
雖然這會更新 &為傳遞的 URL 清除 Facebook 緩存，打印出每個(gè)鍵有點(diǎn)困難它的內(nèi)容并同時(shí)避免錯(cuò)誤，但是我建議使用 var_dump() 或 print_r() 或 PHP-ref
though this will update & clear Facebook cache for the passed URL, it's a bit hard to print out each key & its content and avoid errors in the same time, however I recommended using var_dump() or print_r() OR PHP-ref
使用 PHP-ref
r( facebookDebugger('http://retrogramexplore.tumblr.com/') );
