saveHB: function () { console.log('保存海报'); // wx.navigateTo({ // url: '/pages/hualang/shengchenghb/taskCardPost', // }) var that =this; wx.showLoading({ title: '保存中...', }) wx.downloadFile({ url: that.data.iteminfo.framed_url, success: function (res) { wx.hideLoading() var imageFilePath = res.tempFilePath; if (imageFilePath!='') { wx.saveImageToPhotosAlbum({ filePath: imageFilePath, success: function (data) { wx.showToast({ title: "保存成功", }) }, fail: function (err) { if (err.errMsg === "saveImageToPhotosAlbum:fail:auth denied" || err.errMsg === "saveImageToPhotosAlbum:fail auth deny" || err.errMsg ==="saveImageToPhotosAlbum:fail authorize no response") { // 这边微信做过调整,必须要在按钮中触发,因此需要在弹框回调中进行调用 wx.showModal({ title: '提示', content: '需要您授权保存相册', showCancel: false, success:modalSuccess=>{ wx.openSetting({ success(settingdata) { console.log("settingdata", settingdata) if (settingdata.authSetting['scope.writePhotosAlbum']) { wx.showModal({ title: '提示', content: '获取权限成功,再次点击图片即可保存', showCancel: false, }) } else { wx.showModal({ title: '提示', content: '获取权限失败,将无法保存到相册哦~', showCancel: false, }) } }, fail(failData) { console.log("failData",failData) }, complete(finishData) { console.log("finishData", finishData) } }) } }) } }, complete(res) { wx.hideLoading() } }) } }, }) },
上面的代码是解决权限问题的,还有一个坑就是真机调试是好的,体验版本保存不了,后来发现是图片路径的域名不合法。
