https://developers.weixin.qq.com/miniprogram/dev/api/canvas/Canvas.html [图片] iphone15promax不能画出连续的线，只能一段一段的。 [图片]iphone13 可以画出连续的线。 代码如下： //wxml <canvas canvas-id="signCanvas" class="canvasStyle"      bindtouchstart="onTouchStart"      bindtouchmove="onTouchMove"      bindtouchend="onTouchEnd"></canvas> //script Page({     startX: 0, // Starting X coordinate     startY: 0, // Starting Y coordinate     isDrawing: false, // Flag to check if drawing is happening     ctx: null, // Canvas context     onLoad: function() {         this.ctx = wx.createCanvasContext('signCanvas', this);     },     onTouchStart: function(e) {         this.isDrawing = true;         this.startX = e.touches[0].x;         this.startY = e.touches[0].y;     },     onTouchMove: function(e) {         if (!this.isDrawing) return;         let x = e.touches[0].x;         let y = e.touches[0].y;         this.ctx.moveTo(this.startX, this.startY);         this.ctx.lineTo(x, y);         this.ctx.stroke();         this.startX = x;         this.startY = y;         this.ctx.draw(true); // Add true to keep drawing on the same canvas without clearing previous content     },     onTouchEnd: function(e) {         this.isDrawing = false;     },     clearCanvas: function() {         this.ctx.clearRect(0, 0, 300, 200);         this.ctx.draw();     },     saveCanvas: function() {         wx.canvasToTempFilePath({             canvasId: 'signCanvas',             success: function(res) {                 // res.tempFilePath is the temporary file path of the canvas image                 console.log(res.tempFilePath);                 // You can save this path or upload the image as needed             }         }, this);     } }); //css .canvasStyle {     border: 1px solid #000; /* Basic border for visibility */     width: 300px; /* Width of the canvas */     height: 200px; /* Height of the canvas */ }

已解决：微信8.0.22导致的。更新到最新版本8.0.23就可以了。 通用识别用了快1年了，今天用户反应识别无响应。 身份证识别没问题，但通用识别会报错。 windows开发者工具通用识别没问题，但是IOS真机通用识别报错。 [图片] 代码： wx.chooseImage({         async success (res) {             const tempFilePaths = res.tempFilePaths             let ocr_type=1;             if(_self.SpecialDrug.cardtype===2)ocr_type=8                         let img_url = new wx.serviceMarket.CDN({                         type: 'filePath',                         filePath: res.tempFilePaths[0],                     })                     console.log(ocr_type, img_url)             try {                 wx.showLoading({                   title: '加载中',                   mask: true                 })                 const invokeRes = await wx.serviceMarket.invokeService({                     service: 'wx79ac3de8be320b71',                     api: 'OcrAllInOne',                     data: {                     // 用 CDN 方法标记要上传并转换成 HTTP URL 的文件                       data_type: 3,                       img_url,                       ocr_type                     },                 }) 报错： sale.vue:1365 invokeService fail {message: "invokeService:fail 103 . requestID MLxWDRj8_tTcZ1yLJDZOqQkwzirqocjxOR38_R527Fb8wLO8O7h8lCXvu-U9doTCBVw, error message unknown (callid 0.3930072186727026_1653460060436)", errCode: 103, errMsg: "invokeService:fail 103 . requestID MLxWDRj8_tTcZ1yLJDZOqQkwzirqocjxOR38_R527Fb8wLO8O7h8lCXvu-U9doTCBVw, error message unknown (callid 0.3930072186727026_1653460060436)", requestID: "MLxWDRj8_tTcZ1yLJDZOqQkwzirqocjxOR38_R527Fb8wLO8O7h8lCXvu-U9doTCBVw", line: 2, …}
