Send Custom Field Value with JSON WS Request

[Pawan Thakur, modificado hace 8 años.]

Hello,

I have created an extra field in Document Library using CUSTOM FIELDS feature, so all my documents and Folders will have this field saying BusinessID which is a parameter I will expect from the Webservice Consumers.

I cannot find a reference to how I can send value for this custom field in my ADD FILE or FOLDER requests (JSONWS API calls)

Any help is appreciated.

Thanks,
Pawan

Hi Pawan,

custom field can be passed as attribute of serviceContext parameter. The parameter name to use should be "expandoBridgeAttributes" and should accept a map of values.

Thanks a ton Denis.

Today only, I visited this issue a few hours back and your response is a nice breakthrough.

I found this https://www.liferay.com/documentation/liferay-portal/6.1/development/-/ai/service-conte-1
Its clear that while coding in Java we can use it like serviceContext.setAttribute("trackbacks", null);

Considering that my custom field is ABC the Service context should look like in JSON ?

{"expandoBridgeAttributes": [{"ABC": 100 }]}

Can you give a sample reference. thanks in advance.

Cheers,
Pawan

Hi Pawan,

I'm testing it on Liferay 6.2 CE GA4. I've tryed passing serviceContext in this way {"expandoBridgeAttributes": {"ABC": null}} and it works but whenever I try to put any value for the attribute (different from null) I get the following exception

{"message":"[ expandoBridgeAttributes.values ]: + Could not find a suitable ObjectFactory for interface java.io.Serializable","exception":"flexjson.JSONException"}

At the moment, I'm sorry, I didn't find a way to pass the value of expando attributes.
I'm wondering if we are in a issue or if I'm doing something wrong.

Anyway, I hope this help to get closer to the solution!

Bye,
Denis.

Hi Pawan,

I found the solution reading the JSONWS and inner parameters documentation. Being service contenxt an object the best way to pass expando attributes (instead of a whole JSON object) is to call remote service specifing expando attributes (and values) as inner parameters of service context object (e.g. using cURL) in this way :

curl -H "Accept: application/json" http://[server]:[port]/api/jsonws/[plugin-context-name.][service-class-name]/[service-method-name] -u user:pass -d serviceContext.expandoBridgeAttributes.myAttributeName1={"value A, value B"} -d serviceContext.expandoBridgeAttributes.myAttributeName2={"value C, value D"}

HTH and solve also for you!

Bye!
Denis.
