What is Cross-Origin Cross-origin is a browser-specific concept that refers to JavaScript code accessing sites other than its own origin. For example, if JavaScript code on site A’s webpage requests data from site B, that is cross-origin. For A and B to be considered the same origin, they must have the same protocol (e.g., http and https cannot work together), the same domain name, and the same port number. If you are building apps, mini-programs, or other non-H5 platforms, you will not encounter cross-origin issues. A slight exception is iOS’s WKWebView. In 5+App, or uni-app’s web-view component and renderjs, cross-origin issues can arise due to WKWebView restrictions. For more details, see the special article: https://ask.dcloud.net.cn/article/36348. In uni-app, regular JavaScript code in the App does not run under Webview, so there is no cross-origin issue. Since uni-app uses a standard front-end and back-end separation pattern, when developing H5 applications, if the front-end code and back-end API are not deployed on the same domain server, the browser will report a cross-origin error. # If the Front-end Needs to Call Functions to Connect to UniCloud Cloud Functions In H5 pages, calling functions will be cross-origin. At this time, you need to configure the......

A TikTok order program modification where the frontend doesn’t reflect the changes. FastAdmin development – need to click “Clear Cache” here after every modification. It seems the configuration file update isn’t taking effect. This might be due to ThinkPHP’s configuration cache. Let’s solve it through the following steps: First, confirm the configuration file location and content are correctly modified: “`php // In application/config.php or config/config.php return [ ‘recharge_money_list’ => ‘3610/5000/10000/30000/50000/100000’, // Other configurations… ]; “` Force update the configuration in the controller: “`php public function recharge() { // Force set new configuration \think\Config::set(‘recharge_money_list’, ‘3610/5000/10000/30000/50000/100000’); // Clear cache \think\Cache::clear(); // Print to check configuration dump(config(‘recharge_money_list’)); // Original code… $uid = session(‘user_id’); $this->userInfo = $userInfo = Db::name(‘xy_users’)->where(‘id’, $uid)->field(‘tel,balance,level,all_recharge_num’)->find(); // …other code } “` Or directly override the configuration in the controller: “`php public function recharge() { $money_list = ‘3610/5000/10000/30000/50000/100000’; $list = explode(‘/’, $money_list); $this->assign(‘list’, $list); // Original code… $uid = session(‘user_id’); $this->userInfo = $userInfo = Db::name(‘xy_users’)->where(‘id’, $uid)->field(‘tel,balance,level,all_recharge_num’)->find(); // … } “` If it still doesn’t work, you can try: – Delete cache files under the runtime directory – Restart the PHP service – Check if there are other places overriding this configuration In the template, you can first print to check the......

Record of a Cross-Domain Problem, Micro Disk Frontend uniapp, Backend thinkphp The frontend connects to the API and also uses CDN. I copied solutions from the internet and consulted various AIs. CDN settings: Response header: Access-Control-Allow-Origin Value: * This didn’t work. Modified the Nginx website configuration file in BT panel: add_header Access-Control-Allow-Origin *; add_header Access-Control-Allow-Methods ‘GET,POST’; add_header Access-Control-Allow-Headers ‘DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization’; This also didn’t work. Finally discovered it was because the domain name was too long. You can all try the methods above once. 2025.4.5 Put the compiled frontend and backend in the same directory. The frontend src can be set to an absolute path: /...
