REST API using POST instead of GET

阅读更多关于 REST API using POST instead of GET

问题 Let's assume a service offers some funcionality that I can use like this: GET /service/function?param1=value1&param2=value2 Is it right to say that I can use it with a POST query? POST /service/function { param1 : value1, param2 : value2 } Are these two queries the same? Can I use the second variant in any case or the documentation should explicitly say that I can use both GET and POST queries? 回答1: You can't use the API using POST or GET if they are not build to call using these methods

问题 In an article on preventing PHP form resubmissions, I read the following: (Not quoting) This could be the page that receives the form data, for example called "form.php": <form action="submit.php"> <input type="text" name="user" required /> <input type="password" name="pass" required /> <input type="submit" value="Log in" /> </form> The page that would process the POST data would therefore be called "submit.php".
