//首次请求申请验证,返回echostr
if(echostr!=null){
outputStreamWrite(outputStream,echostr);
return;
}
//验证请求签名
if(!signature.equals(SignatureUtil.generateEventMessageSignature(token,timestamp,nonce))){
System.out.println("The request signature is invalid");
return;
}
应该先验证签名确认它是来源于微信的请求,再返回echostr

只有配置完后的第一次请求会有 echostr 参数数据, 不管是微信官方或非法请求,有这个字段都直接返回,并不影响之后请求的签名校验以及安全性。如对安全性要求比较高的话,使用加密配置,参考 ReceiveServlet2 。

哈哈哈,我就用的这个啊,没问题,而且我选的是加密那种,微信后台加密模式选了兼容模式
