1、授权打开摄像头

doTakePhoto() {let that = thiswx.getSetting({success(res) {// 第一次未授权if (res.authSetting['scope.camera'] === undefined) {wx.authorize({scope: 'scope.camera',success() {// 授权成功...}})}// 第二次未授权else if (!res.authSetting['scope.camera'] && res.authSetting['scope.camera'] != undefined) {wx.showModal({title: '温馨提示',content: `请授权打开您的摄像头，拒绝授权将无法使用该功能`,cancelText: "不授权",confirmText: "继续授权",confirmColor: "#a08250",success(res) {if (res.confirm) {wx.openSetting({withSubscriptions: true,success() {// 授权成功}})}}}, )}// 已授权else {...}},fail(res) {console.log("wx.getSetting调用失败")}})
}

2、授权保存相册

wx.saveImageToPhotosAlbum({filePath: this.data.shareImage,success(res) {wx.showToast({title: '保存图片成功',icon: 'success',duration: 2000})},fail(err) {console.log(err);if(err.errMsg === "saveImageToPhotosAlbum:fail:auth denied" || err.errMsg === "saveImageToPhotosAlbum:fail auth deny" || err.errMsg === "saveImageToPhotosAlbum:fail authorize no response") {wx.showModal({title: '提示',content: '需要您授权保存相册',showCancel: false,success: modalSuccess => {wx.openSetting({success(settingdata) {if(settingdata.authSetting['scope.writePhotosAlbum']) {console.log('获取权限成功，给出再次点击图片保存到相册的提示。')}}})}})}}
})
