如何接收从客户端应用程序传递到jsreport服务器的数据

Question

I am trying to generate a pdf report from my angular app connecting to jsreport. My client app is doing a POST call by passing a sample data to the report server in this way.

 $http.post('http://localhost:5488/api/report', {
      'template': {
        'shortid': 'SypJSv75e',
        "data": {"name": "John Doe"}
      }
    })
    .success(function (response) {
     console.log(response)
    });

As you see in the above code that I am passing {"name": "John Doe"} to the report server.

On the report server, this is the code that I have in the custom scripts section.

function beforeRender(req, res, done) {
req.data.generatedOn = new Date();
done();
}

How do I receive the data in the jsreport that is being passed from client app?

Answer 1

The data property should not be inside the template and your request should look like this

$http.post('http://localhost:5488/api/report', {
      template: { shortid: 'SypJSv75e' },
      data: { name: "John Doe"}
    })
    .success(function (response) {
     console.log(response)
    });

Then you can reach "John Doe" inside template content using {{name}} or in custom script as

function beforeRender(req, res, done) {
  //prints into debug John Doe
  console.log(req.data.name)
  done();
}

You can later consider using jsreport browser javascript client to invoke rendering calls.
