REST API using POST instead of GET

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

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?

Like if your API say /service/function?param1=value1&param2=value2 is accessed by using GET method.

问题 Sorry for another "simple" question, but is there an easy way to read the GET variables from a URL. example.

Rails: Plus sign in GET-Request replaced by space

阅读更多关于 Rails: Plus sign in GET-Request replaced by space

问题 In Rails 3 (Ruby 1.9.2) I send an request Started GET "/controller/action?path=/41_+" But the parameter list looks like this: {"path"=>"/41_ ", "controller"=>"controller", "action"=>"action"} Whats going wrong here?

Therefore, real plus signs must be
