java - springmvc 如何配置微信公众号服务器controller。

Question

调用接口发送消息成功，那服务器配置肯定是对的，但是收不到微信推送的消息，比如关注事件。

    @RequestMapping(value = "/", method = {RequestMethod.GET})
    public String wx(@RequestParam String signature, @RequestParam String timestamp, @RequestParam String nonce, String echostr, HttpServletRequest request, HttpServletResponse response) {
        if (!wxMpService.checkSignature(timestamp, nonce, signature)) {
            LOGGER.info("非法请求， signature：{}", signature);
            return "非法请求";
        }

        if (StringUtils.isNotBlank(echostr)) {
            LOGGER.info("验证：{}", echostr);
            return echostr;
        }

        LOGGER.info("wx:", JSON.toJSONString(request));
        return null;
    }

    @RequestMapping(value = "/", method = {RequestMethod.POST})
    public String service( HttpServletRequest request, HttpServletResponse response) throws Exception {
        LOGGER.info("service, request: {},", JSON.toJSONString(request));

        WxMpXmlMessage inMessage = WxMpXmlMessage.fromXml(request.getInputStream());
        WxMpXmlOutMessage outMessage = wxMpMessageRouter.route(inMessage);
        if(outMessage == null) {
            LOGGER.info("outMessage is null");
            return "";
        }
        return outMessage.toXml();
    }
    

get请求验证配置是通过的，post请求接不到数据，求问题所在,谢谢了

Answer 1

很明显 你指定了 method = {RequestMethod.GET}

Answer 2

produces:指定返回的内容类型，仅当request请求头中的(Accept)类型中包含该指定类型才返回；

Answer 3

没试过request.getInputStream是什么效果，我是这么写的:

@ResponseBody
@RequestMapping(value = "/wechat-listener", method = RequestMethod.POST, produces = "application/xml")
public Message onResponse(HttpEntity<RequestMessage> httpEntity) {

    RequestMessage requestMessage = httpEntity.getBody();

    logger.info("from openid: " + requestMessage.getFrom() +
                "\n type: " + requestMessage.getType());

    return requestMessageHandler.handle(requestMessage);

}

刚刚帮你search了一下，用inputStream是不行的，因为spring-mvc已经把它消耗过了。

谢谢大家回答了，问题已经解决了，是因为项目里使用了security，CROS受限，请求被挡住了，写法什么的没问题

Answer 5

您好，我也遇到了和你一样的问题，请问一下具体查找的思路是什么？我没有配置security，那么我接收不到请求应该从哪块下手解决呢？我的邮箱：jtmjx@163.com，QQ：253552550，麻烦您给我点名一下，谢谢。
