In this article, the example tells about the WeChat public number group sending picture and text message function realized by Python. Shared for your reference, as follows:
In WeChat public development, the use of api are to attach access_token content. Therefore, first you need to get access_token. as follows:
#get microsoft access_token
def get_token():
payload_access_token={
'grant_type':'client_credential',
'appid':'xxxxxxxxxxxxx',
'secret':'xxxxxxxxxxxxx'
}
token_url='/cgi-bin/token'
r=(token_url,params=payload_access_token)
dict_result= (())
return dict_result['access_token']
The media_id of the image that has been uploaded is required when group posting images.Note that the interface must be used when group posting images:/cgi-bin/material/add_material。
# Get the media_ID of the uploaded file
# Group images must use the media_ID provided by the api
def get_media_ID(path):
img_url='/cgi-bin/material/add_material'
payload_img={
'access_token':get_token(),
'type':'image'
}
data ={'media':open(path,'rb')}
r=(url=img_url,params=payload_img,files=data)
dict =()
return dict['media_id']
Subscription number for group sending, must be through the grouping id, first need to get all the users grouping situation.
# Query all user group information
def get_group_id():
url="/cgi-bin/groups/get"
payload_id={
'access_token':get_token()
}
r=(url=url,params=payload_id)
result=()
return result['groups']
You need to select a group for mass mailing, here I select the first valid group for mass mailing (i.e., the first group where the number of users is not 0).
#Returns the first valid group group id.
def get_first_group_id():
groups =get_group_id()
group_id =0
for group in groups:
if(group['count']!=0):
group_id=group['id']
break;
return group_id
The following code is used to send a group text message to the first valid group:
def send_txt_to_first_group(str='Hello World!'):
group_id =get_first_group_id()
pay_send_all={
"filter":{
"is_to_all":False,
"group_id":group_id
},
"text":{
"content":str
},
"msgtype":"text"
}
url="/cgi-bin/message/mass/sendall?access_token="+get_token()
# Need to specify the json encoding will not be transcoded to unicode, otherwise the message will be displayed as unicode code, can not be displayed correctly.
r=(url=url,data=(pay_send_all,ensure_ascii=False,indent=2))# This parameter must be specified here
result=()
# Judge success based on whether the content of the return code is 0 or not
return result['errcode']==0
The following code is used to group images to the first valid grouping.
def send_img_to_first_group(path='/home/fit/Desktop/'):
group_id =get_first_group_id()
pay_send_all={
"filter":{
"is_to_all":False,
"group_id":group_id
},
"image":{
"media_id":get_media_ID(path)
},
"msgtype":"image"
}
url="/cgi-bin/message/mass/sendall?access_token="+get_token()
r=(url=url,data=(pay_send_all))
result=()
# Judge success based on whether the content of the return code is 0 or not
return result['errcode']==0
Here are all the codes:
# -*- coding: utf-8 -*-
import requests
# First get the access_token
import json
#get microsoft access_token
def get_token():
payload_access_token={
'grant_type':'client_credential',
'appid':'xxxxxxxxxx',
'secret':'xxxxxxxxx'
}
token_url='/cgi-bin/token'
r=(token_url,params=payload_access_token)
dict_result= (())
return dict_result['access_token']
# Get the media_ID of the uploaded file
# Group images must use the media_ID provided by the api
def get_media_ID(path):
img_url='/cgi-bin/material/add_material'
payload_img={
'access_token':get_token(),
'type':'image'
}
data ={'media':open(path,'rb')}
r=(url=img_url,params=payload_img,files=data)
dict =()
return dict['media_id']
# Query all user group information
def get_group_id():
url="/cgi-bin/groups/get"
payload_id={
'access_token':get_token()
}
r=(url=url,params=payload_id)
result=()
return result['groups']
#Returns the first valid group group id.
def get_first_group_id():
groups =get_group_id()
group_id =0
for group in groups:
if(group['count']!=0):
group_id=group['id']
break;
return group_id
def send_img_to_first_group(path='/home/fit/Desktop/'):
group_id =get_first_group_id()
pay_send_all={
"filter":{
"is_to_all":False,
"group_id":group_id
},
"image":{
"media_id":get_media_ID(path)
},
"msgtype":"image"
}
url="/cgi-bin/message/mass/sendall?access_token="+get_token()
r=(url=url,data=(pay_send_all))
result=()
print result
# Judge success based on whether the content of the return code is 0 or not
return result['errcode']==0
def send_txt_to_first_group(str='Hello World!'):
group_id =get_first_group_id()
pay_send_all={
"filter":{
"is_to_all":False,
"group_id":group_id
},
"text":{
"content":str
},
"msgtype":"text"
}
url="/cgi-bin/message/mass/sendall?access_token="+get_token()
# Need to specify the json encoding will not be transcoded to unicode, otherwise the message will be displayed as unicode code, can not be displayed correctly.
r=(url=url,data=(pay_send_all,ensure_ascii=False,indent=2))# This parameter must be specified here
result=()
# Judge success based on whether the content of the return code is 0 or not
return result['errcode']==0
if(send_txt_to_first_group("I wish you joy and happiness for your family!")):
print 'success!'
else:
print 'fail!'
Appendix: When using the WeChat Test Subscription to test the mass image interface, the return code is as follows:
{u'errcode': 45028, u'errmsg': u'has no masssend quota hint: [OKvFdA0813ge12]'}
This is because the test subscription doesn't have permission to send group graphic messages, not because of an error in the interface call.
