Try adding an external module to pepper. For the time being, in requests.

Good evening n0bisuke. I'm taking notes of what I was addicted to in pepper development. (Last time => Note on creating your own Box with Pepper's Python)

For python, the request module is great. I want to use it positively when communicating with http ... However, pip cannot be used with pepper, so let's do it with the following procedure.

By the way, the photo is @ ukk0 who recently joined our team. It has nothing to do with the content of the article lol

Refer to Using Requests for HTTP communication of Pepper.

request module

A module that makes http requests nice. There is ʻurllib2`, but it's so easy that it's incomparable.

$ pip install requests

app.py


import requests

r = requests.get('http://qiita.com/n0bisuke/items/d07b5485f4e767bc6e20.json')
print r.json()["title"]

$ python app.py

I'll call you in two lines. It's easy.

Use with pepper

It seems that pip cannot be used with pepper, and it is common to insert the entire directory orz

Download it as a zip from github page and insert the contents requests folder into the choregraphe side.

Create a lib folder and put the requests folder in it. 

After that, edit Python Script like Last article.

app.py


class MyClass(GeneratedClass):
    def __init__(self):
        GeneratedClass.__init__(self)

    def onLoad(self):
        self.framemanager = ALProxy("ALFrameManager")
        self.folderName = None

    def onUnload(self):
        import sys
        if self.folderName and self.folderName in sys.path:
            sys.path.remove(self.folderName)
        self.folderName = None

    def onInput_onStart(self):
        import sys, os
        self.folderName = os.path.join(self.framemanager.getBehaviorPath(self.behaviorId), "../lib")
        if self.folderName not in sys.path:
            sys.path.append(self.folderName)

    def onInput_onStop(self):
        self.onUnload()
        self.onStopped()

self.framemanager.getBehaviorPath (self.behaviorId)," ../ lib ", etc. are like specifying the path to the lib folder created earlier.

I'm not familiar with python, so I won't mention it anymore.

app.py


class MyClass(GeneratedClass):
    def __init__(self):
        GeneratedClass.__init__(self)

    def onLoad(self):
        self.framemanager = ALProxy("ALFrameManager")
        self.folderName = None

    def onUnload(self):
        import sys
        if self.folderName and self.folderName in sys.path:
            sys.path.remove(self.folderName)
        self.folderName = None

    def onInput_onStart(self):
        import sys, os
        self.folderName = os.path.join(self.framemanager.getBehaviorPath(self.behaviorId), "../lib")
        if self.folderName not in sys.path:
            sys.path.append(self.folderName)
        import requests
        r = requests.get('http://qiita.com/n0bisuke/items/d07b5485f4e767bc6e20.json') #← Addendum
        title = r.json()["title"].encode("utf-8") #← Addendum
        self.logger.info(title) #← Addendum

    def onInput_onStop(self):
        self.onUnload()
        self.onStopped()

Now you can finally ʻimport requests`. The rest is the same as the python code I wrote at the beginning.

If you execute it and the parsed character string is displayed in the dialog of the collegraph, it is successful.
