微信小程序将拍摄的图片转为base64字符串

1.将相机拍摄的转为base64字符串

takePhoto: function() {const ctx &＃61; wx.createCameraContext()ctx.takePhoto({quality: &＃39;high&＃39;,success: (res) &＃61;> {console.log(wx.getFileSystemManager().readFileSync(res.tempImagePath, "base64"))}})}

2.将用户从本地相册选取的转为base64字符串

transformBase(res) {let that &＃61; this;var FSM &＃61; wx.getFileSystemManager();//循环将得到的图片转换为Base64for (let r in res.tempFilePaths) {// console.log(res.tempFilePaths[r])FSM.readFile({filePath: res.tempFilePaths[r],encoding: "base64",success: function(data) {let Working &＃61; data.data;that.getBase64ImageUrl(Working)}});}},
