For example, if my original string is "openflow:21", what appears in the datastore is "<span class="error">&#91;openflow - 21&#93;</span>".</p> <p>When using XML, this does not happen; the original string appears in the datastore.</p> <p>Operating System: All<br/> Platform: All</p> CONTROLLER-311

Strings with certain special characters in JSON cause RESTCONF to return 400 Bad Request

(leafref?)<br/> What is the module name of YANG file where this leaf is present?<br/> Is this beheviour seen for every leaf YANG type?</p> <p>That is just a simple string type leaf in any container. Define the following simple config model for your bundle:</p> <p>grouping mydata {<br/> leaf id </p> { type uint64; } <p> leaf data </p> { type string; } <p>}</p> <p>container mycontainer {<br/> list data </p> { uses mydata; key "id"; } <p>}</p> <p>Then try to add an element to this container via restconf, using JSON encoding, where the data string is "openflow:21".</p> <p>What I see in this case is that the POST is successful, but when I try to read back the data (either via restconf, or via the databrokerservice), the string contents turn into "<span class="error">&#91;openflow - 21&#93;</span>".</p> <p>If input string contained colon (<img class="emoticon" src="https://jira.opendaylight.org/images/icons/emoticons/smile.png" height="16" width="16" align="absmiddle" alt="" border="0"/> then it was dealed as namespace:value<br/> and object of type IdentityValuesDTO was created (it is probable that<br/> data could be of type identityref). If data wasn't of type leafref then it<br/> was incorrectly processed as leafref.<br/> The RestCodec was updated to correctly translate data (cases when data<br/> contains ':' but aren't of type leafref)</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/6335/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/6335/</a></p> <p>Merged on 28APR2014</p> <p>So, it turns out it's not just a colon. I can reproduce this in the latest Helium build as long as the string contains an open angle bracket (&lt;) and a colon (<img class="emoticon" src="https://jira.opendaylight.org/images/icons/emoticons/smile.png" height="16" width="16" align="absmiddle" alt="" border="0"/> with the angle bracket coming before the colon.</p> <p>I found this originally by testing this snippet (which I got from the ONF spec for TTPs) against the TTP project at the URL:<br/> <a href="http://localhost:8181/restconf/config/onf-ttp:opendaylight-ttps/onf-ttp:table-type-patterns/" class="external-link" target="_blank" rel="nofollow noopener">http://localhost:8181/restconf/config/onf-ttp:opendaylight-ttps/onf-ttp:table-type-patterns/</a></p> <p>{<br/> "table-type-patterns": {<br/> "table-type-pattern": [<br/> {<br/> "identifiers": [<br/> </p> { "doc": [ "The VLAN ID of a locally attached L2 subnet on a Router." ], "var": "&lt;subnet_VID&gt;" } <p>,</p> { "doc": [ "An OpenFlow group identifier (integer) identifying a group table entry", "of the type indicated by the variable name" ], "var": "&lt;&lt;group_entry_types:name&gt;&gt;" } <p> ]<br/> }<br/> ]<br/> }<br/> }</p> <p>The key line is:<br/> "var": "&lt;&lt;group_entry_types:name&gt;&gt;"</p> <p>Things that fail:<br/> "var": "&lt;&lt;group_entry_types:name&gt;&gt;"<br/> "var": "&lt;group_entry_types:name&gt;&gt;"<br/> "var": "&lt;groupentrytypes:name&gt;&gt;"<br/> "var": "&lt;groupentrytypes:name"<br/> "var": "groupentryt&lt;ypes:name"</p> <p>Things that succeed:<br/> "var": "groupentrytypes:name&gt;&gt;"<br/> "var": "&lt;&lt;groupentrytypes/name&gt;&gt;"<br/> "var": "groupentrytypes:na&lt;me"</p> <p>I'm just running the most recent Helium karaf distro and then running this in install the relevant features:<br/> feature:install standard odl-restconf odl-mdsal-broker odl-mdsal-apidocs odl-ttp-all</p> <p>The error I get back is:</p> <p>{<br/> "errors": {<br/> "error": [</p> { "error-type": "protocol", "error-tag": "malformed-message", "error-message": "Error parsing input: Illegal character in path at index 0: &lt;&lt;groupentrytypes" } <p> ]<br/> }<br/> }</p> <p>should be fixed<br/> <a href="https://git.opendaylight.org/gerrit/11566" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/11566</a></p> <p>The direct e-mail was sent to Giovanni Meo.
