A dictionary of key-value headers for the XMLHttpRequest.
Object.defineProperty(ImageLoaderAjaxOptions.prototype, 'headers',
get: function(),
set: function(value)
)
headers: { [key: string]: string };
Dictionary of key-value headers for the XMLHttpRequest. Default value is an empty dictionary.
If the Method is POST, then the PostData will be sent with the request. So that the endpoint described by
Url may understand the data, add the "content-type" header to Headers with the standard name
for your data serialization (e.g., "application/json"
).
