二维码url转二维码

#### 1、前端二维码url转二维码 ``` <html> <head>  <script type='text/javascript'src='http://cdn.staticfile.org/jquery/2.1.1/jquery.min.js'></script> <script type="text/javascript"src="http://cdn.staticfile.org/jquery.qrcode/1.0/jquery.qrcode.min.js"></script> </head> <body> <div id = "qrid"></div> </body> <script> $(function(){ var qrstr = "http://weixin.qq.com/x/YZ8dQIe7zyjeWazwBqzW"; $('#qrid').qrcode(qrstr);//不指定二维码大写 $('#qrid').qrcode({width: 280,height: 280,text: qrstr});//指定二维码大小 }); </script> </html> ``` #### 2、java二维码url转base64二维码 ``` # 引用依赖 <dependency> <groupId>com.google.zxing</groupId> <artifactId>core</artifactId> <version>3.3.0</version> </dependency> <dependency> <groupId>com.google.zxing</groupId> <artifactId>javase</artifactId> <version>3.3.3</version> </dependency> # java示例 public static String qrcodeToBase64(String url) { Map<EncodeHintType, Object> hints = new HashMap<EncodeHintType, Object>(); hints.put(EncodeHintType.MARGIN, 0); try { BitMatrix bitMatrix = new QRCodeWriter().encode(url, BarcodeFormat.QR_CODE, 256, 256, hints); int[] rec = bitMatrix.getEnclosingRectangle(); int resWidth = rec[2] + 1; int resHeight = rec[3] + 1; BitMatrix resMatrix = new BitMatrix(resWidth, resHeight); resMatrix.clear(); for (int i = 0; i < resWidth; i++) { for (int j = 0; j < resHeight; j++) { if (bitMatrix.get(i + rec[0], j + rec[1])) { resMatrix.set(i, j); } } } int width = resMatrix.getWidth(); int height = resMatrix.getHeight(); BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB); for (int x = 0; x < width; x++) { for (int y = 0; y < height; y++) { image.setRGB(x, y, resMatrix.get(x, y) == true ? Color.BLACK.getRGB() : Color.WHITE.getRGB()); } } ByteArrayOutputStream out = new ByteArrayOutputStream(); ImageIO.write(image, "png", out); base64Encoder base64Encoder = new BASE64Encoder(); return base64Encoder.encode(out.toByteArray()); } catch (Exception e) { log.error("url to qrcode error:{}", e); return null; } } ```
