1.esp8266AP模式初始化

版型选择arduino esp8266

上传代码后,esp8266会发射一个ESP开头的热点打开手机wifi

连接ESP开头的热点会跳入一个配置WiFi的页面(每个esp8266的后缀数字都不一样,但是前缀”ESP”都是一样的)

点击配置WiFi,点击你所知道的WiFi,输入密码

现在esp8266已连接网络了

AP模式的优势是可以随时配置WiFi,而不需要改代码

2.api接口获取网络数据(以网络时间为例)

搜索引擎搜索”时间api”

我们选择”苏宁”的api:http://quan.suning.com/getSysTime.do

点击该网址我们得到一串JSON数据{“sysTime2″:”2021-04-07 17:30:25″,”sysTime1″:”20210407173025”}.我们现在需要将该数据传输到esp8266中

API-url状态码:正确的状态码是”200″,返回其他的都是不正常的.我们可以打开浏览器的F12查看

这样就获取网络时间了

arduino 代码

#define BLINKER_ESP_SMARTCONFIG
#include <ESP8266WiFi.h>
#include <DNSServer.h>
#include <ESP8266WebServer.h>
#include <WiFiManager.h>
#include <FlagHTTPClient.h>
#include <ArduinoJson.h>
#include <FlagJSON.h>

void configModeCallback (WiFiManager *myWiFiManager) {
Serial.println(WiFi.softAPIP());
Serial.println(myWiFiManager->getConfigPortalSSID());
}

FlagHTTPClient _httpClient;
int _httpGET(String url) {
_httpClient.end();
_httpClient.begin(url);
_httpClient.setTimeout(30000);
return _httpClient.GET();
}

JsonVariant _jsonRoot;
DynamicJsonBuffer _jsonBuffer;

void setup(){
  Serial.begin(115200);
  WiFiManager wifiManager;
  wifiManager.setAPCallback(configModeCallback);
  if(!wifiManager.autoConnect()) {
  Serial.println("failed to connect and hit timeout");
  ESP.reset();
  delay(1000);
}
Serial.println("connected...yeey");

  Serial.begin(9600);
}

void loop(){
  Serial.println(_httpGET("http://quan.suning.com/getSysTime.do"));
  Serial.println(_httpClient.getString());
  _jsonBuffer.clear();
  _jsonRoot = _jsonBuffer.parse(_httpClient.getString());
  Serial.println(_jsonRoot.success());
  Serial.println(flagJSON.getJSONDataAsString(_jsonRoot,"sysTime2"));
  delay(10000);
