- 首先下载ESP8266下载工具点击下载烧录固件工具地址
- 将ESP8266插入电脑中，打开工具 ,选择
然后选择烧录好的固件，先擦除
然后地址选为0x0000开始，点击烧录
- 然后下载上传下载文件的工具,uPyCraft下载以及使用
下载完成后，首先打开软件，点击连接串口，进入交互模式REPL
有>>>这个符号，表示成功进入Python环境
在下面的窗口可以输入print('hello world!')
就可以进入今天的主题了！
import urequests
import json
import network
#连接WiFi
sta_if = network.WLAN(network.STA_IF)
if not sta_if.isconnected():
print('connecting to network...')
sta_if.active(True)
sta_if.connect('!!wifiname', '!!passwd')
while not sta_if.isconnected():
pass
print('network config:', sta_if.ifconfig())
#get请求的头部信息
head = {
"User-Agent":'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.105 Safari/537.36'}
#B站获取用户信息的URL
url = 'https://api.bilibili.com/x/relation/stat?vmid=!!yourid&jsonp=jsonp'
#获取信息
r = urequests.get(url,headers = head)
#将信息中需要的部分弄出来
datadict = json.loads(r.text)['data']
print('follower is:' + str(datadict['follower']))
print('following is:' + str(datadict['following']))
#以下是具体返回回来的信息
#{"code":0,"message":"0","ttl":1,"data":{"mid":429xxxx,"following":59,"whisper":0,"black":0,"follower":21}}
注意代码中!!两个感叹号和后面的信息，需要换为你自己的信息，比如!!wifiname,要换位你自己的wifi名字
代码解读
首先是WiFi连接部分，这个自己看手册就OK了，很简单
然后是后面url，这个URL是b站的一个api
https://api.bilibili.com/x/relation/stat?vmid=!!yourid&jsonp=jsonp，其中!!yourid是你访问b站的时候，自己网页上后面的那部分，比如
也就是429xxxx这部分，可以测试一下，比如我放一个
返回的就是一个json字符串换
然后通过json.loads函数可以将json格式的字符串变为字典，后面就可以轻松输出了！
将以上代码复制到代码区
然后点击
下面是micropython输出
这不是我的粉丝数，我随意找了一个up的id放上去的。…

如果没有urequests.py,将下面的文件命名为urequests.py,移入设备文件内
