保存之前先download一下, 把返回的tempFilePath临时文件路径给wx.saveImageToPhotosAlbum的filePath参数wx.downloadFile({ url: 'https://ss0.bdstatic.com/5aV1bjqh_Q23odCf/static/superman/img/logo/logo_white_fe6da1ec.png', success: function (res) { wx.saveImageToPhotosAlbum({ filePath: res.tempFilePath, success(result) { console.log(result) } }) wx.saveFile({ tempFilePath: res.tempFilePath, success: function (res) { console.log(res.savedFilePath) } }) }})
wx.getImageInfo({ src: '../images/shareimg.jpg', success: function (res) { console.log(res.path) wx.getSetting({ success(res) { if (!res.authSetting['scope.writePhotosAlbum']) { wx.authorize({ scope: 'scope.writePhotosAlbum', success() { wx.saveImageToPhotosAlbum({ filePath: res.path, success(result) { console.log(result) } }) } }) } } }) }})
