最近Y cheung 遇到了兩個典型 CORS error問題，XMLHttpRequest 和 Fetch 請求了跨來源資源被瀏覽器阻擋，記錄一下解決方法。 什麼是Cross-Origin Resource Sharing (CORS) 跨來源資源共用？ # Cross-Origin Resource Sharing (CORS) is an HTTP-header based mechanism that allows a server to indicate any origins (domain, scheme, or port) other than its own from which a browser should permit loading resources. CORS also relies on a mechanism by which browsers make a “preflight” request to the server hosting the cross-origin resource, in order to check that the server will permit the actual request. In that preflight, the browser sends headers that indicate the HTTP method and headers that will be used in the actual request.

Drupal 9 多語言站點啟用 Paragraphs 模組，如果在 custom block 中使用了 paragraphs 類型的字段 ，會遇到字段內文字的翻譯無法顯示問題。該 paragraphs 字段的內容始終加載的是 default 的語言內容（通常是英文），需要在custom module 代碼中使用 hook_preprocess_block() 修改一下。

安裝並設置好 Fail2ban 後（可以參考Y Cheung 之前寫的『Fail2ban 配置 Nginx filter』），可以看到在 /etc/fail2ban/filter.d/nginx-badbots.conf 內容如下： 1# /etc/fail2ban/filter.d/nginx-badbots.conf 2# Fail2Ban configuration file 3# 4# Regexp to catch known spambots and software alike. Please verify 5# that it is your intent to block IPs which were driven by 6# above mentioned bots. 7 8[Definition] 9 10badbotscustom = EmailCollector|WebEMailExtrac|TrackBack/1\.02|sogou music spider|(?:Mozilla/\d+\.\d+ )?Jorgee 11 12badbots = Atomic_Email_Hunter/4\.0|atSpider/1\.0|autoemailspider|bwh3_user_agent|China Local Browse 2\.6|ContactBot/0\.2|ContentSmartz|DataCha0s/2\.0|DBrowse 1\.4b|DBrowse 1\.4d|Demo Bot DOT 16b|Demo Bot Z 16b|DSurf15a 01|DSurf15a 71|DSurf15a 81|DSurf15a VA|EBrowse 1\.4b|Educate Search VxB|EmailSiphon|EmailSpider|EmailWolf 1\.00|ESurf15a 15|ExtractorPro|Franklin Locator 1\.8|FSurf15a 01|Full Web Bot 0416B|Full Web Bot 0516B|Full Web Bot 2816B|Guestbook Auto Submitter|Industry Program 1\.0\.x|ISC Systems iRc Search 2\.1|IUPUI Research Bot v 1\.9a|LARBIN-EXPERIMENTAL \(efp@gmx\.net\)|LetsCrawl\.com/1\.0 \+http\://letscrawl\.com/|Lincoln State Web Browser|LMQueueBot/0\.2|LWP\:\:Simple/5\.803|Mac Finder 1\.0\.xx|MFC Foundation Class Library 4\.0|Microsoft URL Control - 6\.00\.8xxx|Missauga Locate 1\.0\.0|Missigua Locator 1\.9|Missouri College Browse|Mizzu Labs 2\.2|Mo College 1\.9|MVAClient|Mozilla/2\.0 \(compatible; NEWT ActiveX; Win32\)|Mozilla/3\.0 \(compatible; Indy Library\)|Mozilla/3\.0 \(compatible; scan4mail \(advanced version\) http\://www\.peterspages\.net/?scan4mail\)|Mozilla/4\.0 \(compatible; Advanced Email Extractor v2\.xx\)|Mozilla/4\.0 \(compatible; Iplexx Spider/1\.0 http\://www\.iplexx\.at\)|Mozilla/4\.0 \(compatible; MSIE 5\.0; Windows NT; DigExt; DTS Agent|Mozilla/4\.0 efp@gmx\.net|Mozilla/5\.0 \(Version\: xxxx Type\:xx\)|NameOfAgent \(CMS Spider\)|NASA Search 1\.0|Nsauditor/1\.x|PBrowse 1\.4b|PEval 1\.4b|Poirot|Port Huron Labs|Production Bot 0116B|Production Bot 2016B|Production Bot DOT 3016B|Program Shareware 1\.0\.2|PSurf15a 11|PSurf15a 51|PSurf15a VA|psycheclone|RSurf15a 41|RSurf15a 51|RSurf15a 81|searchbot admin@google\.com|ShablastBot 1\.0|snap\.com beta crawler v0|Snapbot/1\.0|Snapbot/1\.0 \(Snap Shots&#44; \+http\://www\.snap\.com\)|sogou develop spider|Sogou Orion spider/3\.0\(\+http\://www\.sogou\.com/docs/help/webmasters\.htm#07\)|sogou spider|Sogou web spider/3\.0\(\+http\://www\.sogou\.com/docs/help/webmasters\.htm#07\)|sohu agent|SSurf15a 11 |TSurf15a 11|Under the Rainbow 2\.2|User-Agent\: Mozilla/4\.0 \(compatible; MSIE 6\.0; Windows NT 5\.1\)|VadixBot|WebVulnCrawl\.unknown/1\.0 libwww-perl/5\.803|Wells Search II|WEP Search 00 13 14failregex = ^<HOST> -.*"(GET|POST|HEAD).*HTTP.*"(?:%(badbots)s|%(badbotscustom)s)"$ 15 16ignoreregex = 17 18datepattern = {^LN-BEG}%%ExY(?P<_sep>[-/.])%%m(?P=_sep)%%d[T ]%%H:%%M:%%S(?:[.,]%%f)?(?:\s*%%z)? 19 ^[^\[]*\[({DATE}) 20 {^LN-BEG} 21 22# DEV Notes: 23# List of bad bots fetched from http://www.user-agents.org 24# Generated on Thu Nov 7 14:23:35 PST 2013 by files/gen_badbots. 25# 26# Author: Yaroslav Halchenko 如果沒有找到這個文件，請新建一個，或者將 apache-badbots.conf 拷貝並重命名。

默認情況下，crond 會將所有的輸出或者錯誤信息通過email發送給執行用戶。Y CHEUNG 一個沒注意就超過mailgun的每月免費額度，2個月了，趕緊查找問題解決它。

因需找出了多年不用的移動硬碟SSD，結果win 10 無法讀取！檢查了驅動什麼的都沒問題，也看到有這個硬碟了，就是不能正常加載出來，著急。 原本還以為是TOSHIBA的問題，因為看到網上有說win 10更新後無法正常使用東芝硬碟的，但是那都是2018年的事情了啊，應該早修復了呀。
