上面是我兩php文件的代碼，當(dāng)我點(diǎn)擊login.php輸出的鏈接后跳轉(zhuǎn)到第二個(gè)php里，就報(bào)錯(cuò)誤
【Graph returned an error: 無(wú)法加載網(wǎng)址: 這個(gè) URL 的域名未包含應(yīng)用的域名。為了能夠加載 URL，請(qǐng)?jiān)趹?yīng)用設(shè)置的應(yīng)用域名字段添加應(yīng)用的所有域和子域?！?/p>

我已經(jīng)在facebook開(kāi)發(fā)者平臺(tái)添加了這個(gè)域名，我也仔細(xì)檢查了url也沒(méi)發(fā)現(xiàn)不一樣的地方，不知道為什么還報(bào)這個(gè)錯(cuò)誤，麻煩弄過(guò)facebook登錄的朋友幫我看看。
