HTTP Post

Hi

How to use http post to pass parameters to url.

[former_member205497]

Hi,

I have the same error as Raffaele. After adding the postParams parameter of type java.util.Map to the Suspend-plug the WebDynpro gives the following error during build:

Outbound plug (of type 'Suspend') 'suspend_plug' may have at most two parameters: 'url' of type 'string' and 'postParams' of type 'Map'.

I use SAP NetWeaver Developer Studio version 7.0.16. (If this does not work in this version in which version does it work?)

Does someone know a solution? I would highly appreciate it.

Thanks in advance.

Hi Ayyapparaj KV,

I just did what you said, but I have always the error which I wrote before.

When I create the suspend plug Developer Studio add automatically the Url (type String) parameter.

But when I add the postParams parameter (type java.util.Map), developer Studio shows me the error.

Sorry Bertram,

but I added a postParams parameter of java.utils.Map and I have still the error.

If I write only Map in the type of parameter, I can't create the parameter to plug.

Maybe have I add any library to UsedDC Component?

Hallo Raffaele,

which NW 7.0 Developer Studio version do you use?

SAP NetWeaver Developer Studio

Version: 7.0.09

The error is :

Controller Ifa3_009WinInterfaceView [suspend_plug]: Outbound plug (of type 'Suspend') 'suspend_plug' may have at most two parameters: 'url' of type 'string' and 'postParams' of type 'Map'.

Hi,

I think suspend plugs are not available in this version.

But I created my Suspend Plug. And I added a Suspend Property to my Application. So I think they're supported.

Hi,

Then select java native type

Click on the browse button

type Map and select the one which is from the java.util package.

Does the parameter type must be java.util.Map?

Hi Bertram,

I tried to add a PostParams parameter to a Suspend Plug, as you said, but Developer Studio give me an error when I add new parameter to plug. Do you know why?

Thanks,

Raffaele

Hallo Rafaele,

the parameter MUST be named postParams and it MUST be of type Map. Please try this.

As other people have said before, I get the same error as they do; ei

"Controller PersonMasterInterfaceView : Outbound plug (of type 'Suspend') 'redirectToJSP' may have at most two parameters: 'Url' of type 'string' and 'postParams' of type 'Map'."

They do rigth now have Url of type string (love the non-capital letter s of String btw), and postParams of type java.util.Map . I have tried to change the Url to url, postParams to PostParams but still get the same error.

I'm running 7.0 SP17.

Any help would be appreciated.

Hi,

maybe you can use Suspend & Resume Plugs? Have a look here: [Suspend and Resume Plug|http://help.sap.com/saphelp_nw70/helpdata/en/68/3aee42c4257176e10000000a1550b0/frameset.htm]

Hi,

Do you want to pass POST parameters FROM a Webdynpro to another webdynpro/servlet or pass parameters TO a webdynpro?

no actually my req is that i have to navigate to a url from my webdynpro app and i need to pass som parameters also. How to go for that using HTTP Post

Hallo Swetha,

this is possible, allthough it is some kind of "not-so-obvious" Web Dynpro features, I admit.

Sending POST parameters with Web Dynpro Suspend Plugs

1) Define a an additional Suspend Plug parameter (besides 'Url' of type String) with name 'postParams' and of type Map.

2) In your controller code create a HashMap instance and put some key/value-pairs in it:

Map postParams = new HashMap();

postParams.put("Key1", "Value 1");

postParams.put("Key2", "Value2");

postParams.put("Key3", "Value 3");

wdThis.wdGetWDSuspendResumeWindowController().wdFirePlugTestSupend("http://www.sap.com", postParams);

3) RESULT: The Web Dynpro Java Runtime will then pass these parameters via a POST request to the Suspen/Resume target application like the following HTTPWatch-Log demonstrates:

00:00:02.817 0.253 1812 POST 405 text/html http://www.sap.com/?sap-wd-resumeurl=http%3A%2F%2Fwdfd00181849a%3A57000%2Fwebdynpro%2Fdispatcher%2Fl...

and the following three POST-Parameters Key3=Value3&Key1=Value1&Key2=Value2

Hi Bertram,

I am also trying this concept.

But getting the same error. I tried to add a postParams plug of type java.util.Map. but it is giving me a error as

"Controller XXXInterfaceView [out]: Outbound plug (of type 'Suspend') 'out' may have at most two parameters: 'Url' of type 'string' and 'postParams' of type 'Map'. XXXInterfaceView.wdcontroller"

What will be the reason?

I am in NWDS7.0.14.
