Set Body for POST Call via HTTP Assertion

[siddharth-b]

Hi guys I am working on layer7 8.3 Policy manager. I need to make a POST call using policy assertion.

For making call I am using HTTPS Route assertion. 

 

How can I add a body in policy? I need to add JSON Body which has to be attached as a body to HTTPS Route assertion.

 

Sample example:

URL - POST https://api.data.com

Body - application/json

{

"name":"layer7",

"something":"nothing"

}

You may want to try setting a context variable for request with the body.

If I set a context variable for Message name request then check my request.mainpart it seems to return what I set in the variable. 

This link discusses using the set context variable assertion to set messages,

Set Context Variable Assertion - CA API Gateway - 8.3 - CA Technologies Documentation 

 

Hope that helps some.

Hi siddharth-b ,

You can create a new message as Charles suggested, and set it as "Request Source" of the route via http(s) assertion.

Hi Zhijun,

 

I am trying to do the same but getting an error. 

 

I created a context variable(say x) in which I selected, 

Data Type: Message

Content-Type: application/json

Expression: I defined my JSON that I need to send as PUT HTTP call to my target

 

Then in Route via HTTPS, I selected my request source as above context variable(x).

 

So when I try to send the request, I am getting the following error,

 

Variable x is not a String and cannot be converted to one. (Actual type: com.I7tech.message.Message)

 

Can you please suggest and help?

It seems you have an audit detail assertion and trying to log your custom request message directly, as the error suggested, the your request is a message, not a string, you cannot log it directly, if you want to log the body of the message, you can log the ${x.mainpart}

 

You may already know it, if you need to send PUT request, on route via http(s) properties, select PUT from the dropdown list for "HTTP Method"

Thanks!! I was directly logging with ${x} as it was a context variable. But now I got it, if request is a message, we need to log using ${x.mainpart}

Following up on this.....  Posting a saml response via a browser is usually done as follows:

 

<form method="post" action="https://sp.example.com/SAML2/SSO/POST" ...>
<input type="hidden" name="SAMLResponse" value="response" />
<input type="hidden" name="RelayState" value="token" />
...
<input type="submit" value="Submit" />
</form>

 

For some reason , need the gateway itself to do this POST. How would I set a context variable to build this msg that I would use in the route via https assertion? In other words, need to build an HTTP request with the following:

 

<input type="hidden" name="SAMLResponse" value="response" /> 
<input type="hidden" name="RelayState" value="token" /> 

 

type="hidden" probably not neede... since only relevant for browser..

 

 

Thanks
