Sending data from javascript/html page to Express NodeJS server

问题 I'm working on a cordova application, using html5 and javascript. The architecture is the following one : the phone application requests something to the server, which asks a firebird database. The database answers to the server which gives the asked data to the phone application (in html5 / javascript). I've been able to send the data from the server to the phone with JSON, and I thought it would be the same to send some data from the phone app to the server. However, I have no idea how to

Check that write()/send() can process whole buffer without block, fail otherwise (no partial write)

由 北战南征 提交于 2019-12-07 09:40:22
问题 I am using SOCK_SEQPACKET connection, and it is critical for me to ensure that whole buffer is sent with single write()/send() call. I am also operating with device driver that is designed to handle a complete block of data with single call. At the same time I want to handle the situation when write()/send() blocks due to buffer overflow, i.e. I want to have a feedback whether current implementation gets a bottleneck here. I'm working with glibc, Linux 2.6. I need to implement a method that

Send_mail in Django, works in shell, works locally, not in view

由 a 夏天 提交于 2019-12-07 05:04:39
问题 I'm not even sure how to debug this: I'm using send_mail in one of my views in Django. It works fine when using the app locally (using the same SMTP settings I use in production), and it works fine from the shell in production (again, using the same settings). But when I actually use the app in production, the message doesn't send. Any idea how to troubleshoot? I won't paste in the whole view, but here's the relevant section. if request.method == 'POST': message, form = decideform(request

Is there a way for the application to track who was in the To: line if and when the user actually pushes Send? Thanks very much! Nick 回答1: No. At least not currently... If you

What is the point of using “send” instead of a normal method call?

由 自作多情 提交于 2019-12-06 18:34:54
问题 as far as I understand 'send' method, this some_object.some_method("im an argument") is same as this some_object.send :some_method, "im an argument" So what is the point using 'send' method? 回答1: It can come in handy if you don't know in advance the name of the method, when you're doing metaprogramming for example, you can have the name of the method in a variable and pass it to the send method. It can also be used to call private methods, although this particular usage is not considered to
