My app started by another app, and at initiating it must get POST parameters. I read that i can get GET parameters using Window.Location.getParameter . But I need to get POST parameter from request. How to implement it?
"get" in getParameter() means "retrieve", it's the standard Java naming convention for getters; it has nothing to do with the HTTP request method.

I have a problem with my JMeter code, particularly with type of variables that are returned by JDBC Request.
This because then i have to make a json with this variables and therefore is most important the type of them otherwise my rest web service returns error.
I made this code:
The problem is on global_state variable because jdbc request save it as a string but the value is a float in my rest service.
What is the solution?
I also tried to use Beanshell PreProcessor to convert it without any result.
Thanks
I think that it resolved, or won't fail during the http request, with this code:
"grid_voltage": "${grid_voltage_1}"
I was using spring-security-oauth2-1.0.0.RELEASE.jar and was able to access /oauth/token via GET method to generate tokens.
When I updated to spring-security-oauth2-2.0.6.RELEASE.jar, GET method was not supported. I am now only able to access /oauth/token to generate tokens via POST method.
Also "org.springframework.security.oauth2.provider.approval.TokenServicesUserApprovalHandler" was found missing in the new jar. Can anyone explain the reason?
Plz Help!
Thanx in advance
This is because the OAuth 2.0 specification mandates that requests to the token endpoint must use the POST method. See https://www.rfc-editor.org/rfc/rfc6749#section-3.2 which says:
The client MUST use the HTTP "POST" method when making access token
requests.
I want to understand how a RESTful web service identifies if a correct request method is called.
For example,
I have a REST service it exposes one operation which is of type GET.
Assume a REST client has invoked the operation using a wrong request method(PUT).
In this scenario, how the service/framework identifies a correct request method is invoked?
I have gone through various posts to understand the scenario but I don't find any information.
Please let me know your comments.
The first line sent in an HTTP request looks like this:
GET /index.html HTTP/1.1
The HTTP request thus contains the HTTP method (POST, PUT, GET, etc.). The framework reads this method, and invokes the Java method that is mapped (thanks to annotations, or XML configuration, or whatever) to the URL (also contained in the HTTP request, as shown above) and the HTTP method. If none is found, then an error response is sent back (405 Method Not Allowed, if the resource is found, but with another method, or 404 if the resource is not found).
It's the http protocol not REST that checks headers, and reports back with an error code.
REST is sort of a strategy, not an implementation.
Hope this helps.
Hi I was just curious when is the doPut() method in a servlet called. I know that if the form on a jsp/html page has a "post" method then the doPost() is called otherwise if it has a "GET" then the doGet() is called.When is the doPut() called ??
When an HTTP PUT request is received, naturally.
Can a page do a PUT request by code?
The only valid method attribute values of a <form> are get and post, according to the HTML5 spec. I assume that's what you're asking.
The doPut() method handles requests send by using the HTTP PUT method. The PUT method allows a client to store information on the server. For an example, you can use it to post an image file to the server. As the above answer says, goGet() and doPost() are in use, mostly. In my case, I use only these two, and I am getting only get requests, so I simply transfer the get request to doPost() and do my job easily.
if you want to send some confidential values in url via form you must use the post method, If you will use the get method for the form like login the values parameters like userid and password will be visible in url and anyone can hack that thing. So better to use post method in forms. By default it will call get method.
in get the url is like http://url?method=methodname&userid=123&password=123
so if you use post method the url will be like this http://url/methodname.do
I'm trying to make it possible to use full functionality of my Jersey webservice by both using regular HTTP method calls (GET,PUT,POST,DELETE), and specifying the method in URL while using POST method.
So to delete /resource client will be able to use:
DELETE /resource
or
POST /resource?method=DELETE
Does jersey support that? Or what would be the least-intrusive way to implement that?
The only way I can think of would be writing a Filter which wraps the original HttpServletRequest with my class whose getMethod returns the parsed HTTP method from the URL. Is this the only solution?
Thanks in advance.
Just add PostReplaceFilter to your app: http://jersey.java.net/nonav/apidocs/latest/jersey/com/sun/jersey/api/container/filter/PostReplaceFilter.html
