Content types

The Content-Type field in HTTP headers indicates in which format the data is sent to, or returned by, the HTTP methods of the Rule Execution Server REST API.

For each method, the Response Content sections provide details and examples of the format in which data is sent in requests and objects are returned in responses. To read the details for a method, click View Schema or View Example in the page of the REST API reference manual for that method.

Content description

The Rule Execution Server REST API supports the following content types:

application/xml

XML is the default content type of the response. For details about the format of each returned object, see the XML schema specifications for each operation. You can also find the object definitions by retrieving the WADL (Web Application Description Language) file.

application/json

As an alternative to setting the Content-Type HTTP headers, you can include the format in the URI path, after the version number. Example:

POST /api/v1/json/ruleapps?...

application/octet-stream

This content type produces a file. Some services require that you send a BLOB data section.

If the action receives the application/octet-stream MIME type, provide your file as is.
As an alternative to sending the file as the body part of the HTTP request, you can include the BLOB data directly in the XML or JSON representation, in one of two ways:
- Encode the file in Base64 and pass it as a value for the body part.
- Use a multipart POST request. To post a valid multipart request, write the XML or JSON code in a part named body. All other parts of the request can receive files and have a unique identifier. In this case, the system always handles the BLOB section as an identifier and picks the corresponding file in the multipart request. The fallback is the classic system BLOB representation in Base64.
Example:
```
curl 
   --form body=@request.xml 
   --form MyArchiveReference=@ruleset.jar 
   --user resAdmin:resAdmin http://localhost:9080/res/apiauth/ruleapps/MyRuleApp/1.0/rulesets
```
In this example, the request.xml file contains the following XML code:
```
<ruleset>
   <name>MyName</name>
   <version>1.5</version>
   <displayName>Hello World !</displayName>
   <archive>MyArchiveReference</archive>
</ruleset>
```
