1、授权打开摄像头
doTakePhoto() {
let that = this
wx.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。')
}
}
})
}
})
}
}
})
