read
read(stringToParse: String | Binary, contentType: String = "application/dw", readerProperties: Object = {}): Any
Reads a string or binary and returns parsed content.
This function can be useful if the reader cannot determine the content type by default.
Parameters
Name | Description |
---|---|
|
The string or binary to read. |
|
A supported format (or content type). Default: |
|
Optional: Sets reader configuration properties. For other formats and reader configuration properties, see Supported Data Formats. |
Example
This example reads a JSON object { "hello" : "world" }'
, and it uses the
"application/json"
argument to indicate input content type. By contrast,
the output application/xml
directive in the header of the script tells the
script to transform the JSON content into XML output. Notice that the XML
output uses hello
as the root XML element and world
as the value of
that element. The hello
in the XML corresponds to the key "hello"
in the JSON object, and world
corresponds to the JSON value "world"
.
Example
This example reads a string as a CSV format without a header and transforms it
to JSON. Notice that it adds column names as keys to the output object. Also,
it appends [0]
to the function call here to select the first index of the
resulting array, which avoids producing the results within an array (with
square brackets surrounding the entire output object).
