获取方式
ESP8266发起HTTP请求+解析json数据
获取粉丝API:
https://api.bilibili.com/x/relation/stat?vmid=349513188
API浏览器测试返回结果

实际结果
开发方式/硬件平台
Arduino IDE + ESP8266 NODEMCU板子
实现步骤
-
安装ArduinoIED 开发发环境
这个非常简单，直接搜官网地址下载即可。https://www.arduino.cc/en/software
-
添加开发板
链接地址：
https://arduino.esp8266.com/stable/package_esp8266com_index.json -
安装项目需要的库
#include <ESP8266WiFi.h> // 本程序使用ESP8266WiFi库
#include <WiFiClient.h>
#include <ESP8266HTTPClient.h>
#include <WiFiClientSecureBearSSL.h>
#include <ArduinoJson.h>
其中ArduinoJson 库需要单独安装，其他选好开发板就会自动安装
- CV大法
这个过程比较漫长就不一一记录了，反正遇到了挺多坑，也学到了很多知识
直接上最终版本代码
#include <ESP8266WiFi.h> // 本程序使用ESP8266WiFi库
#include <WiFiClient.h>
#include <ESP8266HTTPClient.h>
#include <WiFiClientSecureBearSSL.h>
#include <ArduinoJson.h>
const char* ssid = "AQST"; // 连接WiFi名
const char* password = "123456789"; // 连接WiFi密码（此处使用123456789为示例）
const String host = "https://api.bilibili.com";
const String path = "/x/relation/stat?vmid=";
const String uid = "349513188";
const unsigned char fingerprint[] = {0x00,0xb3,0x57,0x0f,0xaa,0x95,0xc7,0x03,0xeb,0x78,0x30,0xd9,0xfc,0xd8,0x2b,

代码解释
- GPIO2是开发板自带的一颗LED灯
- AQST是我电脑开的热点名字
- 123456789是电脑开的热点的密码
