微博登錄php

『壹』 用官網的php SDK做的微博登錄API，登錄後一直出現500錯誤，求解（下面是callback的代碼）

500是服務端錯誤了

『貳』 如果用php語言獲取新浪微博某一網址的源碼

我試著用file_get_contents()來獲取了一下，是能獲取到源碼的。

var_mp((file_get_contents('http://weibo.com/p/1005051893289714/')));

不過確實顯示的如你說的那樣，只有頁面title顯示為「Sina Visitor System」，但是這個時候，因為使用了var_mp()來列印，可以看到頁面上還顯示了：string(5405) ""。

這說明file_get_contents返回了還是比較多的內容，再來查看一下源代碼，發現返回的是一些js語句，這些語句當然是不會顯示在頁面上的，裡面還有外部js，那麼你獲得源碼之後，因為js路徑不對(它使用的是相對地址)，所以也會引起js報錯，而導致js沒有運行：

<scripttype="text/javascript"src="/js/visitor/mini.js"></script>

正常情況下，我們打開http://weibo.com/p/1005051893289714/這個網頁之後，看到的其實是這個js執行之後的跳轉頁面。

『叄』 如何獲取新浪微博的登錄參數

1、用Chrome的開發者工具或者Firefox的Firebug來進行抓包
找到login.php文件，就可以看到此文件的一些請求參數，

『肆』 新浪微博網站接入，怎麼實現接入網站的

有一個代碼，加進來就可以了，需要你程序員添加

『伍』 php讓用戶使用新浪微博賬號登錄我的網站一般要保存那些參數到資料庫

uid針對你的網站是固定的，access_token可以說不是固定的，但是有效期很長，他是用來確定用戶授權的有效期，具體可參見官方文檔。
access_token
用於調用access_token，介面獲取授權後的access
token。
expires_in
access_token的生命周期，單位是秒數。
remind_in
access_token的生命周期（該參數即將廢棄，開發者請使用expires_in）。
uid
，當前授權用戶的UID。
