【问题描述】：

我制作这个功能是为了可以向我的 google home mini 发送通知，但我不停地收到错误代码 400（错误请求）。我尝试使用多种方法。

在 Home-Assistant 中，我已经设置了我的 Google Home，并且可以通过它播放媒体，但是每当我使用 Home-Assistant 的“google_say”API 进行尝试时，它都不起作用。

我还尝试使用名为“API 客户端”的应用程序通过手机调用 Home-Assistant API，但得到了相同的响应。

    function ttsGoogleHome(text) {
    var ttsUrl = "http://127.0.0.1:8123/api/services/tts/google_say?api_password=<MY_PASSWORD>"
    var varToken = "<MY_TOKEN>"
    
    var postData = {"entity_id": "media_player.david", "message": `${text}`};
  
      let axiosConfig = {
        headers: {
            'authorization': `Bearer ${varToken}`,
            'Content-Type': 'application/json',
            "Access-Control-Allow-Origin": "*",
        }
      };
  
      axios.post(ttsUrl, postData, axiosConfig)
      .then((res) => {
        console.log("RESPONSE RECEIVED: ", JSON.stringify(res));
      })
      .catch((err) => {
        console.log("AXIOS ERROR: ", JSON.stringify(err));
      })
    }

这是我在服务器中得到的响应：

        {
          "message": "Request failed with status code 400",
          "name": "Error",
          "stack": "Error: Request failed with status code 400\n

【解决方案1】：

我发现了我的错误。

我用错了api链接

这是正确的调用方式。

function ttsGoogleHome(text) {
var ttsUrl = "http://127.0.0.1:8123/api/services/tts/google_translate_say?api_password=APIPASSWORD"
var varToken = "TOKEN"

var postData = `{"entity_id": "media_player.david", "message": "${text}", "language": "de"}`;

  let axiosConfig = {
    data: null,
    headers: {
        'authorization': `Bearer ${varToken}`,
        'Content-Type': 'application/json',
        "Access-Control-Allow-Origin": "*",
    }
  };

  axios.post(ttsUrl, postData, axiosConfig)
  .then((res) => {
      console.clear();
    console.info("RESPONSE RECEIVED: ", JSON.stringify(res));
  })
  .catch((err) => {
      console.clear();
    console.error("AXIOS ERROR: ", JSON.stringify(err));
  })

}

这里也是我的configuration.yaml：

# Configure a default steup of Home Assistant (frontend, api, etc)

# Text to speech
tts:
  - platform: google_translate
  - language: "de"
  - service_name: google_say
  -base_url: http://192.168.0.176:8123
group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml

homeassistant:
  auth_providers:
   - type: legacy_api_password
     api_password: !secret http_password
