API

EffectCameraStream.offPlay

基础库 2.19.0 开始支持本方法,低版本需做兼容处理

取消监听相机开启事件,取消后 EffectCameraStream.onPlay 中的回调参数将不被触发。

语法

EffectCameraStream.offPlay(callback)

参数说明

function callback

回调参数

代码示例

预期表现:点击按钮后弹出相机授权弹窗(如果未曾授权),授权后相机开启,但无弹窗提示。

<button type="primary" bindtap="requestEffectCamera">打开相机</button>
Page({
  onShow: function (options) {
    this.effectCameraStream = tt.createEffectCameraStream(this);
    this.effectCameraStream.onError(this.onError);
    this.effectCameraStream.onRequest(this.onRequest);
    this.effectCameraStream.offRequest(this.onRequest);
    this.effectCameraStream.onPlay(this.onPlay);
    this.effectCameraStream.offPlay(this.onPlay);
  },
  requestEffectCamera() {
    this.effectCameraStream.request({
      orientation: "front",
    });
  },
  onError(error) {
    console.log("onError", error);
    const { type, errMsg } = error;
    tt.showModal({
      title: `onError ${type}`,
      content: errMsg,
    });
  },
  onRequest() {
    console.log("相机资源申请成功");
    this.effectCameraStream.play();
  },
  onPlay(cameraVideo) {
    tt.showToast({
      title: "相机打开",
    });
    console.log("相机数据", cameraVideo);
  },
});
