Token verification. Use the get method. Request entry, using the psot method. A public account or a lightweight application portal is a url. The same url can be divided into get and post. The four parameters are not null and must be verified. Parameters must also be verified during post, but echostr is not output.
During post, echostr may be empty. Do you want to check whether echostr is empty? Since no output is required, verification is not required.2. Access Credential access_token

Public static boolean checkSignature (TokenCheck tokenCheck ){

If (tokenCheck. getDevMode ()! = Null) {return true;} return checkSignature (tokenCheck. getSignature (), tokenCheck. getTimestamp (), tokenCheck. getNonce ());
