Need to know the format of Get Content REST API response

Sandeep B

Hello, I am basically not from the ContentServer development team. and my core skill set is MS Dynamics 365. We are looking to use 'Get Content' REST API to download the file using below

REST API (UI is Dynamics CRM). 

https://developer.opentext.com/alpha/cs.exe/api/v1/nodes/{id}/content/{filename}

I have tried using C# code to get the content. What is the format of the Content response? and how can I use the content to save it as a file?

Please advise. Any programming language example works for me.

 var client = new RestClient("https://xxxx.****.com/OTCS/cs.exe/api/v2/nodes/41681696/content/.pdf");

   client.Timeout = -1;

   var request = new RestRequest(Method.GET);

   ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

   request.AddHeader("otcsticket", "/NVhbnazqiWRBbXQzdSJm7RG1B5q+jFomnx8qBWmdYxK83d4WqtlV9WX1oIrBe/21CWDHAlArQkaZy5wtFlK46lsZHU6TVY5iVoQwX35X/0zqg5ixjN9aA==");

   request.AlwaysMultipartFormData = true;

   request.AddParameter("action", "download");

   IRestResponse response = client.Execute(request);

  Console.WriteLine(response.Content);

  

And also please find the attached sample content response. If I save it as a file, it won't work. 

Best Regards

Hi Sandeep,

I can't talk to C# so well. But in node, it will reply in chunks that you can write to a buffer and write the buffer out.

Here is a simple example that is slightly modified using vanilla node.js

const https = require('https');
const fs = require('fs');


const options = {
    'method': 'GET',
    'hostname': 'cshost.domain.com.au',
    'path': '/otcs/cs.exe/api/v2/nodes/1234/content',
    'headers': {
        'OTDSTicket': 'generated ticket'
    }
};


const req = https.request(options, function (res) {
    let chunks = [];


    res.on("data", (chunk) => {
        chunks.push(chunk);
    });


    res.on("end", (chunk) => {
        let body = Buffer.concat(chunks);
        fs.writeFile('./sample.pdf', body, (err => {
            if (err) {
                console.error('Bad stuff happened');
            } else {
                console.log('hmmmmm tre bien');
            }
        }))
    });


    res.on("error", (error) => {
        console.error(error);
    });
});


req.end();
