阅读更多关于 No documentation about AppSecret Proof for Server API calls?

问题 If I enable the option giving in Advanced Settings is gives me BAD Request or error code 400 If I enable this option, what is the required value of AppSecret_Proof parameter? 回答1: If you visit github and have a look at their PHP SDK's code, you'll find how they generate appsecret_proof's value. This part was recently added so you have to refer to the latest version of PHP SDK. To activate/inactivate, as you already know, you have to visit App Dashboard > Setting > Advanced.

Why can't server side and client side scripts interact?

阅读更多关于 Why can't server side and client side scripts interact?

问题 I'm new to client and server side scripts, and I was wondering, how come they can't interact? The major difference Code Conquest stated here is that: ... is called a client side language is because it runs scripts on your computer after you’ve loaded a web page. And A server side or back-end language runs its scripts before the HTML is loaded, not after. Even if the server side script (e.g. PHP) has already been executed, how come it can't be changed (with JavaScript) after the page has

iOS Push Notification SSL Certificate

阅读更多关于 iOS Push Notification SSL Certificate

Is the certificate generated to send push notifications specific to the server, or I can use it on any other server, if I change my server? Thank you. You can use it in any server. Apple push notification SSL certificate is not specific to any server. Example: parse.com, xtify.com etc. You can use it on any server -- its the certificate and its corresponding private key that matters, not the IP from which the connection is made. You can use it in any server. Apple push notification SSL certificate is not specific to any server. https://developer.apple.com/library/archive/documentation

Implementing Comet on the database-side

阅读更多关于 Implementing Comet on the database-side

This is more out of curiosity and "for future reference" than anything, but how is Comet implemented on the database-side? I know most implementations use long-lived HTTP requests to "wait" until data is available, but how is this done on the server-side? How does the web server know when new data is available? Does it constantly poll the database? What DB are you using? If it supports triggers , which many RDBMSs do in some shape or form, then you could have the trigger fire an event that actually tells the HTTP request to send out the appropriate response. Triggers remove the need to poll...

Web Application Internationalization, do it server-side or client-side?

阅读更多关于 Web Application Internationalization, do it server-side or client-side?

问题 We are looking to internationalize a web application. Is it best to output translation Server-side (it is written in .net 4 C#) or Client-side (Javascript)? We have already begun carrying this out Client-side by creating a JS file which contains a single object containing English phrases as the Keys (so developers understand what each message means in context), with values that are the string which is shown to the client for any alerts and prompts. We are thinking of extending this to all

Securing AJAX Requests via GUID

阅读更多关于 Securing AJAX Requests via GUID

问题 I'm writing a web app that will be making requests via AJAX and would like to lock down those calls. After a little research, I am considering using some form of random token (string) to be passed back along with the request (GUID?). Here's the important parts of my algorithm: Assign a token to a JavaScript variable (generated server-side). Also, store that token in a DB and give it a valid time period (i.e. 10 minutes). If the token has still not been used and is within it's valid time

Can you reliably set or delete a cookie during the server side processing of an Ajax (XHR) call?

阅读更多关于 Can you reliably set or delete a cookie during the server side processing of an Ajax (XHR) call?

问题 I have done a bit of testing on this myself (During the server side processing of a DWR Framework Ajax request handler to be exact) and it seems you CAN successfully manipulate cookies, but this goes against much that I have read on Ajax best practices and how browsers interpret the response from an XmlHttpRequest. Note I have tested on: IE 6 and 7 Firefox 2 and 3 Safari and in all cases standard cookie operations on the HttpServletResponse object during Ajax request handling were correctly

Does react-dom/server work on the client-side?

阅读更多关于 Does react-dom/server work on the client-side?

I need to render top-level html tags on the client-side (for example, <html><head>...</head><body></body></html> ). The result will be injected into an iframe. On the server, I would use the renderToStaticMarkup function from react-dom/server , but the client-only react-dom doesn't have this function. Will react-dom/server work on the client in the latest version of react (currently 15.3.0)? If so, is there any indication from the react dev team that it will continue to be supported on the client in future versions? tl;dr: yes. I verified that it works in react@15.3.0 .
