[英]How to send data from an android application (client) to a python flask (backend) remote server
First of all bear with me as I'm new to both android applications and python flask. 首先要忍受我,因为我是android应用程序和python flask的新手。
I found sample code (java) on the web, which sends json data from an android application to a php web page ( http://hmkcode.com/android-send-json-data-to-server/ ). 我在网上找到了示例代码(java),该示例代码将android程序中的json数据发送到php网页( http://hmkcode.com/android-send-json-data-to-server/ )。 What I want to do is to use this sample android code to send the data to a remote VPS server and use python flask as backend to receive and save the data .
我想做的是使用此示例android代码将数据发送到远程VPS服务器,并使用python flask作为后端来接收和保存数据。
As far as I understand the first thing that I have to replace is the php-address http://hmkcode.appspot.com/jsonservlet with my server's IP address (99.99.999.99) in the java code, 据我了解,我必须替换的第一件事是在Java代码中使用服务器IP地址(99.99.999.99)的php-address http://hmkcode.appspot.com/jsonservlet ,
switch(view.getId()){
case R.id.btnPost:
if(!validate())
Toast.makeText(getBaseContext(), "Enter some data!", Toast.LENGTH_LONG).show();
// call AsynTask to perform network operation on separate thread
//new HttpAsyncTask().execute("http://hmkcode.appspot.com/jsonservlet");
new HttpAsyncTask().execute(99.99.999.99);
break;
}
Then I have to add the python flask code which will receive the data. 然后,我必须添加将接收数据的python flask代码。
Concerning flask I found the following code which might apply to my issue, https://github.com/javierchavez/Android-with-flask-backend/blob/master/Backend/wsgi.py . 关于flask我发现以下代码可能适用于我的问题: https://github.com/javierchavez/Android-with-flask-backend/blob/master/Backend/wsgi.py 。
Thus my questions are : 因此,我的问题是:
1st Is it correct to only replace the php-address with my VPS IP address, or do I also have to add the path to the flask file in my remote's server home directory. 1st仅将php-address替换为我的VPS IP地址是否正确,或者我还必须在远程服务器的主目录中添加flask文件的路径。
2nd what would be the actual flask code, which will receive the data from the application and save it to the remote server (as far as I understand the python flask file will be saved in the VPS's home directory) 第二个实际的flask代码是什么,它将从应用程序接收数据并将其保存到远程服务器(据我了解,python flask文件将保存在VPS的主目录中)
3rd do I also have to take into consideration the password required to access my VPS remote server when modifying the android and flask code? 第三 ,修改Android和Flask代码时,我还必须考虑访问VPS远程服务器所需的密码吗?
Thank you in advance 先感谢您
回答第一个问题,仅在烧瓶服务器的根(“ /”)路径上声明了您要执行的操作时才指定IP是正确的,否则您必须附加在@app中指定的路径.route()标记。
