Class Details

merge(options?: RequestOptionsArgs) : RequestOptions

Creates a copy of the RequestOptions instance, using the optional input as values to override existing values. This method will not change the values of the instance on which it is being called.

Note that headers and search will override existing values completely if present in the options object. If these values should be merged, it should be done prior to calling merge on the RequestOptions instance.

console.log('req.method:', RequestMethod[req.method]); // Post
console.log('options.url:', options.url); // null
console.log('req.url:', req.url); // https://google.com
