How can we upload data to s3 on CodeName One?

[gao1...@gmail.com]

I want to upload like this:

// Initialize the Cognito Sync client

CognitoSyncManager syncClient = new CognitoSyncManager(

getApplicationContext(),

Regions.US_EAST_2, // Region

credentialsProvider);

// Create a record in a dataset and synchronize with the server

Dataset dataset = syncClient.openOrCreateDataset("myDataset");

dataset.put("myKey", "myValue");

dataset.synchronize(new DefaultSyncCallback() {

@Override

public void onSuccess(Dataset dataset, List newRecords) {

//Your handler code here

}

});

Above code snipped is the source for the native android development to upload the data to s3

Please let me know the same way used in Codename One

I'm not familiar with that API but you need to use the REST API that AWS provides and not the Java API which is designed for Java EE.

If you can reference a specific REST API I can explain to you how to translate that to Codename One code.

Dear Shai

Thanks for your support.

I tried to find the restful api to sync the data to s3, but I could only the api to upload the file, not sync the data to s3.

And Codename One doesn't provide the api to sync the data as well, so I'm not sure how I can implement this problem using Codename One.

Please help me to indicate the way to fix the issue.

I'm looking forward to your answer.

Best regards,

Xander

Hi,

as far as I know and have used S3 I only used it as a file upload API and haven't used it as anything else.

If you have a specific REST API from Amazon that you need to do in Codename One I can help you with that but I'm just not familiar enough with the API to understand what you are trying to accomplish.

Hi Shai

I understand and I will use my own restful api

I have one more question: Why I can't import JSONObject on codename one?

Can you show the full example to use the Post restful api?

There is a cn1lib that includes JSONObject we have our own JSON parser. 

There is some discussion of using a webservice in this video https://www.codenameone.com/how-do-i-use-http-sockets-webservices-websockets.html

As well as here:

https://www.codenameone.com/blog/terse-rest-api.html

[gao guangli]

Hi Shai

Yes, I saw the above links but terse is not worked for http post(because of the cast Respose<Map> to Map<String, Object>)

And I got the source you posted as well:

ConnectionRequest post = new ConnectionRequest(){
    @Override
    protected void buildRequestBody(OutputStream os) throws IOException {
        os.write(json.toString().getBytes("UTF-8"));
    }

    @Override
    protected void readResponse(InputStream input) throws IOException {
       // parse response data
    }
};
post.setUrl("http://localhost:8093/halimatbank/cbs/staff");
post.setPost(true);
post.setContentType("application/json");

I tried above code but the buildRequestBody() is not invoked and never worked.

Seems that I missed one configuration.

Would you like to hint me what I'm missing?

Regards

Did you add it to the network queue using addToQueue?

[gao guangli]

Hi Shai

I missed to use the addToQuee.. Now it is working

And I have one more question: Which app can I use on the phone to scan the QR code to run the build?

Thanks

I just use anything that comes up with "QR code Scanner" they pretty much all work.

[gao guangli]

Hi Shai

Do you have the navigation sample or video using new GUI build?

I'm not sure how I can make the register, login and main page.

Just bind an action listener to a button that will trigger that event then in the code use otherForm.show(); or new OtherForm().show();

We'll try to add a module to the academy with the new GUI builder
