微信推送消息

我们先那测试环境试一下 和真实环境几乎无差别（微信公众开发平台）

测试环境： 

https://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=sandbox/login 

 

 

其实很多东西都是固定的  

和个人发消息：

import json

import requests

# 其实就好比我们的cookie一样 需要给你关注的用户一个token

# 1. 伪造浏览器向 https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential... 发送GET请求，并获取token
r1 = requests.get(
    url = "https://api.weixin.qq.com/cgi-bin/token",
    params = {
        "grant_type": "client_credential",
        "appid":"wxe022764ef61336e9",     #这个是你的信息
        "secret": "29def1418cdd8c8317fd5ad39a127890"   #也oypXF000rxnm9-5PTTaVM851sXL4是捏信息
    },
)


access_token = r1.json().get('access_token')
print(access_token)




wx_id = "oypXF000rxnm9-5PTTaVM851sXL4"  # 这个是关注你的微信的别人的id

body = {
    "touser": wx_id,
    "msgtype": "text",
    "text": {
        "content": '老王'  # 这个是你要给别人发送的信息
    }
}
r2 = requests.post(
    url="https://api.weixin.qq.com/cgi-bin/message/custom/send",
    params ={
        'access_token': access_token,

    },
    data=bytes(json.dumps(body, ensure_ascii=False), encoding='utf-8')
)
print(r2.text)

如果要发模板信息就要先去开发平台增加模板内容

r1 = requests.get(
    url = "https://api.weixin.qq.com/cgi-bin/token",
    params = {
        "grant_type": "client_credential",
        "appid":"wxe022764ef61336e9",
        "secret":"29def1418cdd8c8317fd5ad39a127890"
    }
)
access_token = r1.json().get('access_token')

wx_id = "oypXF000rxnm9-5PTTaVM851sXL4"

body = {
    "touser": wx_id,
    "template_id": 'dD0dm09eqDra4TlbFjXiPlO5fb00Fjz0IL_cyprIkJM',  # 这个是你的在微信开发平台设置的模板id
    "data": {
        "user": {
            "value": "老王",  # 这个是拼接的内容  可以给你的模板中凭借内容
            "color": "#173177"  # 颜色
        }
    }
}

r2 = requests.post(
    url="https://api.weixin.qq.com/cgi-bin/message/template/send",
    params={
        'access_token': access_token
    },
    data=json.dumps(body)
)

print(r2.text)

我们来写一个微信可以推送信息的界面

 views：

    return render(request,"login.html",{"msg":"用户名或密码错误"})
