如何最小化HTTP请求中的大量数据？

Question

I have an application made in Java for Android platforms, and I need to send quite a lot of data, the data I am sending is the previous weeks SMS messages received and sent. That includes the following data:

• Sent by Phone number
• Sent by Name
• Sent to Phone number
• Sent to Name
• Time sent
• Message

And you can imagine this data can be really big for some people so I need a way to minimize/encrypt it on one side, and then using an HTTP request I can send it over to my server, and decrypt this data with PHP. What is the best method to do this? What size limit does HTTP POST have?

Answer 1

I think you should zip+encrypt(say, using aes) the data on Android side before sending the data to your server and decrypt+unzip it on the server side.

Post size depends on the config on the server side -> What is the size limit of a post request? .

ps why would anyone want to send all their sms messages to your server? :)

Answer 2

You'll want to send the data using an HTTP POST. The limit on the HTTP POST size depends on the server receiving the data. For example a PHP server has the post_max_size property that (I think) by default is 16M. In terms of encryption start by making sure the request is being sent over HTTPS.

Answer 3

Do you have Gzip option turn on in your Apache HTTPD server?

This way the web server will compress and serve slightly packed files to and bro your browser.
