re-posting this question with different information.
I have 3 parameters.
response.writeHead(200,
{
'Content-Type': 'text/json'
});
response.end({ID:'bufid',Name: bufname,address: bufaddrss});
}
This is not working. Here I want to send to the end user in 200 Ok a JSON Body as:
{'ID; :'123',
'Name': 'alice',
'address': 'xxxxx'}
Here bufid,bufname and bufaddrss are values which are determined by functions and which can be accessible any where (they are global)
how can I send that information
First you have to realize that the following:
{ID:'bufid',Name: bufname,address: bufaddrss}
is not JSON. JSON is a protocol. It is a string that encodes a javascript object with a syntax that is similar to javascript object literal syntax (hence the confusion and mix-up most people have with the term "JSON").
You first need to convert that object to JSON formatted string. Fortunately node comes with a built in method: JSON.stringify().
response.end(
JSON.stringify({ID: bufid,Name: bufname,address: bufaddrss})
);
