Read and write files with Slackbot ~ Bot development with Python ~

In this article, I will explain the process of reading and writing files with Slackbot created in Python.

" Control reading and writing files with Python " We will make it possible to call the logic implemented in in from Slackbot.

The basic logic for reading and writing files uses the following modules created in "Controlling reading and writing of files with Python".

import codecs

class FileReadWrite:

    #Method to read file
    def file_read(self, path):
        try:
            #Open file
            target_file = codecs.open(path, "r", "utf_8")
            #Read the file
            text = target_file.read()
            target_file.close()
        except:
            #Exception handling when an error occurs
            text = "ng"

        return text

    #Method to write file
    def file_write(self, path, text):
        try:
            target_file = codecs.open(path, "a", "utf_8")
            target_file.write(text)
            result = "ok"
            target_file.close()
        except:
            #Exception handling when an error occurs
            result = "ng"
        return result

Read " Create Slackbot in Python " for the basics of implementing Slackbot in Python. ..

Implementation of Slackbot write processing ◆ Operating specifications Call the write method from the above module and return a reaction depending on the result. If the write is successful, the reaction is ": ok:", and if the write is unsuccessful, the reaction is ": ng:".


from slackbot.bot import respond_to
from slackbot.bot import listen_to
from filereadwrite import FileReadWrite

@respond_to('^File write test$')
def write_test(message):
    #Instantiate a class
    f = FileReadWrite()
    #Write to file
    action = f.file_write("./test1.txt", "AIUEO\n")
    #React the result
    message.react(action)

◆ Execution result </ span> <img src = "https:: //miyabi-knock.com/tools/wp-content/uploads/2018/12/slackbot_write.png "width =" 500 "alt =" write file "class="alignnone size-large" />

Implementation of Slackbot loading process ◆ Operating specifications Call the loading method from the above module and return text or reaction depending on the result. If the reading is successful, the contents of the file will be output. If the reading fails, the reaction of ": ng:" is returned.

◆ Contents to be described in botmodule.py </ span> Add the reading logic.

@respond_to('^File read test$')
def read_test(message):
    #Instantiate a class
    f = FileReadWrite()
    #Read text from file
    text = f.file_read("./test1.txt")

    #When it fails, NG is returned as a reaction
    if text == "ng":
        message.react(text)
    else:
        #Returns text on success
        message.reply(text)

◆ Execution result </ span> <img src = "https:: //miyabi-knock.com/tools/wp-content/uploads/2018/12/slackbot_read.png "width =" 500 "alt =" execution result "class="alignnone size-large" />

This is the implementation of file read / write logic in Slackbot.
