How to get JSON content from a RESTful server to a Android client?
提问by jan
I've built a REST server that automatically retrieves data from my database and returns it as JSON. I want to know, how I can get this JSON content to my mobile and turn it into a string so that I can store this in the mobile's database.
我构建了一个 REST 服务器，它自动从我的数据库中检索数据并将其作为 JSON 返回。我想知道，如何将这个 JSON 内容发送到我的手机并将其转换为字符串，以便我可以将其存储在手机的数据库中。

First you need to be able to parse your JSON string. For a simple parser I gave an answer earlier here: getting Json result in AndroidJust parse through the list and add them to the database. There are different database tutorials out there.
首先，您需要能够解析 JSON 字符串。对于一个简单的解析器，我之前在这里给出了一个答案： 在 Android 中获取 Json 结果只需解析列表并将它们添加到数据库中。那里有不同的数据库教程。

To make it as easy as possible try to find out small tutorials for different sub tasks like REST to JSON and database handler.
为了尽可能简单，尝试找出不同子任务（如 REST 到 JSON 和数据库处理程序）的小教程。
Here is a tutorial for JSON parsing from a REST webservice:
