Amazon web services 使用amazon mqtt从esp8266发布按键

在mongoose操作系统中，我有以下代码打印到我的串行控制台。我可以在amazon aws和mdash中在线查看该设备。我从发布中返回了一个0，但它从未向aws mqtt发送消息。我已在mqtt的测试中订阅了该主题，因此不确定我做错了什么

load("api_gpio.js");
load("api_mqtt.js");
load("api_sys.js");
let pin = 0;
GPIO.set_button_handler(
  pin,
  GPIO.PULL_UP,
  GPIO.INT_EDGE_NEG,
  50,
  function (x) {
    let topic = "mOS/topic1";
    let message = JSON.stringify({
      total_ram: Sys.total_ram(),
      free_ram: Sys.free_ram(),
    });
    let ok = MQTT.pub(topic, message, message.length);
    let test = ok;
    let res = MQTT.pub("mOS/topic1", JSON.stringify({ a: 1, b: 2 }), 1);

    print(res);
    print("Published:", res ? "yes" : "no");
  },
  true
);
print("Flash button is configured on GPIO pin", pin);
print("Press the flash button now!");

MQTT.sub(
  "mOS/topic1",
  function (conn, topic, msg) {
    print("Topic:", topic, "message:", msg);
  },
  null
);

我确信我已经满足了所有这些要求

有效连接

有效且有效的证书

允许所需连接和操作的策略

我有一个mos默认策略，包含以下内容

{
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "iot:*",
      "Resource": "*"
    }
  ],
  "Version": "2012-10-17"
}

有以下的mos.yml文件。我在应用程序中有aws.crt.pem和aws.key.pem文件

    apply:

        ESP_IDF_SDKCONFIG_OPTS: >
          ${build_vars.ESP_IDF_SDKCONFIG_OPTS}
          CONFIG_FREERTOS_UNICORE=y

返回false，我不确定如何调试此

我遵循了这里的每一条指示，包括互联网按钮视频

好，它又开始工作了，我需要在amazon中删除设备，然后再次运行mos aws设置命令

所以真正的问题是，每次我更新代码时，我的设备都会闪烁，这会覆盖我的wifi设置、aws设置和mdash设置

多亏了另一家公司的帮助，这帮我解决了这个问题

Use mos call FS.List to get a directory listing of the files in your device
Use mos get to retrieve your credentials and save them locally in your fs dir.
E.g.:

$ mos get aws-esp32_807A98.key.pem > fs/aws-esp32_807A98.key.pem
$ mos get aws-esp32_807A98.crt.pem > fs/aws-esp32_807A98.crt.pem
$ mos get ca.pem > fs/ca.pem
Use mos config-get to read your config, or just copy from that verbose output you get when you initialize your device. Save those to mos.yml.
E.g.:

["aws.thing_name", ""]
["mqtt.enable", true]
["mqtt.server", "a1234b5678cde-ats.iot.us-east-2.amazonaws.com:8883"]
["mqtt.ssl_ca_cert", "ca.pem"]
["mqtt.ssl_cert", "aws-esp32_807A98.crt.pem"]
["mqtt.ssl_key", "aws-esp32_807A98.key.pem"]
So, when you re-flash, you re-write your credentials and configure your device with the same data again.
