## springboot开发微信环境搭建 ##

--------------------

需要用到IntelliJ IDEA、[微信公号测试平台][Link 1]、springboot、内网穿透（本地开发比较方便，这里我用的是小米球内网穿透）  
请自行建立springboot项目  
首先我们需要登录到微信测试开发平台,接口配置信息如下图:

我们在配置的时候需要建立springboot项目,将项目运行起来才可以配置成功，我们先去建立controller类，类里面的请求方法：

@Controller
    public class WechatController {
    	@GetMapping("/wx")
        @ResponseBody
        public String login(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) {
            String signature = httpServletRequest.getParameter("signature");
            String timestamp = httpServletRequest.getParameter("timestamp");
            String nonce = httpServletRequest.getParameter("nonce");
            String echostr = httpServletRequest.getParameter("echostr");
            if (CheckUntil.checkSignatures(signature, timestamp, nonce)) {
                return echostr;
            }
            return null;
        }
        }

建立微信工具类和SHA1加密类：

public class CheckUntil {
    
        private static final String token = "这里写的你的token";
    
        public static boolean checkSignatures(String signature, String timestamp, String nonce) {
            String[] strings = new String[]{nonce, token, timestamp};
            Arrays.sort(strings);
            StringBuffer stringBuffer = new StringBuffer();
            for (String string : strings) {
                stringBuffer.append(string);
            }
            if (SHA1.encode(stringBuffer.toString()).equals(signature)) {
                return true;
            }
            return false;
        }
    }
    
    public final class SHA1 {
    
        private static final char[] HEX_DIGITS = {'0', '1', '2', '3', '4', '5',
                '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};
    
        /**
         * Takes the raw bytes from the digest and formats them correct.
         *
         * @param bytes the raw bytes from the digest.
         * @return the formatted bytes.
         */
        private static String getFormattedText(byte[] bytes) {
            int len = bytes.length;
            StringBuilder buf = new StringBuilder(len * 2);
            // 把密文转换成十六进制的字符串形式
            for (int j = 0; j < len; j++) {
                buf.append(HEX_DIGITS[(bytes[j] >> 4) & 0x0f]);
                buf.append(HEX_DIGITS[bytes[j] & 0x0f]);
            }
            return buf.toString();
        }
    
        public static String encode(String str) {
            if (str == null) {
                return null;
            }
            try {
                MessageDigest messageDigest = MessageDigest.getInstance("SHA1");
                messageDigest.update(str.getBytes());
                return getFormattedText(messageDigest.digest());
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
        }
    }

这时候运行项目之后，我们就可以继续配置微信接口，。
