single-page-application

问题 I'm working in a SPA in React that doesn't use React Router to create any Routes; I don't need to allow users to navigate to specific pages. (Think multi-page questionnaire, to be filled in sequentially.) But, when users press the back button on the browser , I don't want them to exit the whole app; I want to be able to fire a function when the user presses the back button that simply renders the page as it was before their last selection. (Each page is a component, and they're assembled in

问题 If the source code or function is changed in the SPA project, you must deploy it to the server again. If the service is deployed, it will continue to load the cached js value unless refreshed. How do I fix this? 回答1: Say all of your SPA code are two files: vendor.js and app.js . To miss the cache when updated, typically what is done is compute hashes of the contents and put it in the file name: vendor.<truncated md5 hash>.js and app.<truncated md5 hash>.js . Each time you build the project

问题 I am working on Single Page Architecture (SPA) Web application. I am have implemented functionality to dynamically load different pages of application. This is what my spa.js looks like var spa = { init: async () => { await import('./page.js') spa.data['page'].apply() }, register: (page, data) => { spa.data[page] = data }, data: {}, } window.onload = () => { spa.init() } And this is what my page.js looks like const pageData = { apply: () => { document.body.innerHTML = getMSG() } } function

问题 My understanding is that, if you include your login page in your SPA, then the user is receiving all of your code before they're even authenticated. And yet, it seems to be a very common practice. Isn't this incredibly insecure?? Why or why not? 回答1: An SPA would have all the page structures (html and javascript code for the design of pages), but obviously not data. Data would be downloaded in subsequent ajax requests, and that is the point. To download actual data, a user would have to be

问题 I want to get my UIWebView 's current location when browsing an SPA (single-page-application) website. (Yes, I am intentionally working with UIWebView instead of WKWebView .) I know that there are multiple approaches to getting the current URL, such as: webView.request?.url?.absoluteString webView.request?.mainDocumentURL?.absoluteString webView.stringByEvaluatingJavaScript(from: "window.location") However, for an SPA website, for each of the approaches above, I am getting the initial url,

问题 I've been reading the OAuth2 specs over and over, but I can't figure out one thing. Isn't the Authorization Code flow without Client Secret (which is now recommended for single page apps) highly insecure because it can easily be used for phishing? Let me explain: The Client redirects the Resource Owner to the Authorization Server, passing the Redirect URL and Client ID. The Resource Owner approves the request and the Authorization Server redirects him to the given Redirect URL and passes the

问题 I have the following asp.net core spa application configured (react-redux template) public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { app.UsePathBase(new PathString("/foo")); if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } else { app.UseExceptionHandler("/Error"); } app.UseStaticFiles(); app.UseSpaStaticFiles(); app.UseRouting(); app.UseEndpoints(endpoints => { endpoints.MapControllerRoute( name: "default", pattern: "{controller}/{action=Index}/{id?}"); }

问题 The Sanctum Auth system on my local machine works well and I have no errors. But my deployed app is having trouble with authorizing a user. When I login it sends a request to get the user data then redirects. After auth completes you are redirected and the app make a GET request for more data. This GET route is guarded using laravel sanctum. But the backend is not registering that the user has made a successful login attempt so it sends a 401 Unauthorized error. Here is some code... loadUser
