PUT HTTP Adapter in MobileFirst Platform

Question

I am trying to post some data from my native android application.

Native Code:

WLProcedureInvocationData invocationData = new WLProcedureInvocationData("TaskAdapter", "updateTask");

int taskId = Integer.parseInt(tvTaskId.getText().toString());

String assignedTo = tvAssignedTo.getText().toString();

String address = "";

String description = "";

String latitude = "5.0";

String longitude = "5.0";

String status = "5.0";
String comments = "5.0";
String lastupdate = "5.0";
String userLatitude = "5.0";
String userLongitude = "5.0";
String userLocation = "5.0";
String photoData = "5.0";

Object[] parameters = new Object[]{
    taskId,
    assignedTo,
    description,
    address,
    latitude,
    longitude,
    status,
    comments,
    lastupdate,
    userLatitude,
    userLongitude,
    userLocation,
    photoData
};

invocationData.setParameters(parameters);

WLRequestOptions options = new WLRequestOptions();
options.setTimeout(30000);


client.getInstance().invokeProcedure(invocationData, new MyInvokeListener(), options);

Adapter Code:

function updateTask(id) {   
    var input = {
        method : 'PUT',
        returnedContentType : 'json',
        path : '/Api/Task?taskid=' + id
    };


    return WL.Server.invokeHttp(input);
}

Adapter XML:

        </connectionPolicy>
    </connectivity>

    <procedure name="getAllTasks" />
    <procedure name="updateTask" />


</wl:adapter>

I am not sure whether I am sending body in the right way. Moreover, how do I send the id (parameter) to the adapter function.

When I click Call Mobile First Adapter in eclipse, it is showing me the procedure name but the REST call type as GET in the drop down, I want it as PUT.

You will need to update your adapter code as follow:

function updateTask(id, assignedTo, description, address, latitude, longitude,
        status, comments, lastupdate, userLatitude, userLongitude,
        userLocation, photoData) {

    var data = {
        "assignedTo" : assignedTo,
        "description" : description,
        "address" : address,
        "latitude" : latitude,
        "longitude" : longitude,
        "status" : status,
        "comments" : comments,
        "lastupdate" : lastupdate,
        "userLatitude" : userLongitude,
        "userLocation" : userLocation,
        "photoData" : photoData
    };

    var input = {
        method : 'PUT',
        returnedContentType : 'json',
        path : '/Api/Task?taskid=' + id,
        body : {
            contentType : 'application/json',
            content : data
        }
    };

    return WL.Server.invokeHttp(input);
}

Since you are passing the values to the adapter via invocationData.setParameters(parameters); in your native code that means the adapter will take that same number of parameters in the same order.

I created an object data that will contain all these values except the id or taskId since you are passing it as a query param. Then I'm assuming your back-end services accepts a Content-Type of application/json, you can change the content-type if need be.
