How to fix a 'mixed content' warning after switching to HTTPS?
Jul 02, 2025 am 12:43 AM
瀏覽器提示“混合內(nèi)容”警告是因為HTTPS頁面中引用了HTTP資源，解決方法是：1.檢查網(wǎng)頁中的混合內(nèi)容來源，通過開發(fā)者工具查看控制臺信息或使用在線工具檢測；2.替換資源鏈接為HTTPS或相對路徑，將http://改為https://或使用//example.com/path/to/resource.js格式；3.更新CMS或數(shù)據(jù)庫中的內(nèi)容，逐個替換文章和頁面中的HTTP鏈接，或用SQL語句批量替換；4.設置服務器自動重寫資源請求，在服務器配置中加入規(guī)則強制跳轉(zhuǎn)HTTPS。
當你把網(wǎng)站從 HTTP 切換到 HTTPS 后，瀏覽器卻提示“混合內(nèi)容”警告，這通常是因為頁面中仍然引用了部分通過 HTTP 加載的資源。簡單來說，HTTPS 頁面里混用了 HTTP 的內(nèi)容，瀏覽器就會認為這個頁面不安全。
解決這個問題的核心是：找出所有使用 HTTP 的資源，并將它們改為 HTTPS 或相對協(xié)議。
1. 檢查網(wǎng)頁中的混合內(nèi)容來源
混合內(nèi)容通常來自以下幾種情況：
- 圖片、腳本（JS）、樣式表（CSS）使用的是
http://地址 - 第三方插件或廣告加載的是非 HTTPS 資源
- 網(wǎng)站數(shù)據(jù)庫中保存的舊鏈接仍為 HTTP
你可以通過瀏覽器開發(fā)者工具（F12 打開）查看控制臺（Console）標簽，會看到類似 “This page is trying to load mixed content” 的提示，里面會列出具體的 HTTP 請求地址。
建議做法：
- 用 Ctrl+F 或搜索功能在網(wǎng)頁源碼中查找
http:// - 使用在線工具如 Why No Padlock 來檢測你的網(wǎng)址是否存在混合內(nèi)容問題
2. 替換資源鏈接為 HTTPS 或使用相對路徑
找到這些 HTTP 鏈接后，下一步就是修改它們：
- 如果資源本身支持 HTTPS（大多數(shù)現(xiàn)代 CDN 和外部服務都支持），直接把
http://改成https:// - 如果不確定是否支持 HTTPS，可以先去掉協(xié)議部分，只保留
//example.com/path/to/resource.js，這樣瀏覽器會自動繼承當前頁面的協(xié)議（HTTP 或 HTTPS）
舉個例子：
<!-- 有問題 --> <script src="http://example.com/script.js"></script> <!-- 改成 HTTPS --> <script src="https://example.com/script.js"></script> <!-- 或者用相對協(xié)議 --> <script src="//example.com/script.js"></script>
3. 更新 CMS 或數(shù)據(jù)庫中的內(nèi)容
如果你的網(wǎng)站是用 WordPress、Shopify、Joomla 這類系統(tǒng)搭建的，很多內(nèi)容可能存儲在數(shù)據(jù)庫中，比如文章里的圖片鏈接、自定義 HTML 插入的內(nèi)容等。
這時候需要：
- 登錄后臺，逐個檢查文章和頁面內(nèi)容，替換里面的 HTTP 鏈接
- 使用 SQL 查詢語句批量替換數(shù)據(jù)庫中的鏈接（適用于熟悉數(shù)據(jù)庫操作的用戶）
例如，在 WordPress 中可以用如下 SQL 命令：
UPDATE wp_posts SET post_content = REPLACE(post_content, 'http://yourdomain.com', 'https://yourdomain.com');
注意備份數(shù)據(jù)庫后再執(zhí)行此類操作。
4. 設置服務器自動重寫資源請求（可選進階）
如果你不想手動一個個改鏈接，也可以考慮在服務器配置中加入規(guī)則，自動將資源請求重寫為 HTTPS。
比如在 Apache 的 .htaccess 文件中添加：
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]或者 Nginx 配置中設置強制跳轉(zhuǎn) HTTPS。
此外還可以使用 HTTP 響應頭 Content-Security-Policy 來阻止加載 HTTP 資源，但這更適合高級用戶。
基本上就這些方法。修復混合內(nèi)容其實不復雜，但容易因為遺漏某些靜態(tài)資源而反復出錯。關(guān)鍵是要耐心排查每個引用點，尤其是那些隱藏在代碼深處或數(shù)據(jù)庫里的鏈接。

Solution: urllib3 ProxySchemeUnknown(proxy.scheme)
Feb 29, 2024 pm 07:01 PM
The reason for the error is that the ProxySchemeUnknown(proxy.scheme) error of urllib3 is usually caused by the use of an unsupported proxy protocol. In this case, urllib3 does not recognize the proxy server's protocol type and therefore cannot use the proxy for network connections. To resolve this issue, you need to ensure that you are using a supported proxy protocol, such as HTTP or https. How to resolve To resolve this issue, you need to ensure that you are using a supported proxy protocol, such as HTTP or HTTPS. You can solve this problem by setting the proxy parameters of urllib3. If you are using an http proxy, the code example is as follows: importurllib3http

Using HTTPS for data transmission in Java API development
Jun 18, 2023 pm 10:43 PM
With the development of science and technology, network communication has become one of the important tools for information transmission in modern society. But at the same time, information transmission on the network faces the risk of malicious attacks and theft, so security is particularly important. Based on this, the HTTPS protocol came into being. It is a protocol that adds SSL/TLS encryption to the HTTP protocol to ensure network transmission security. As a language widely used in network development, Java naturally provides a rich API to support the HTTPS protocol. This article will
