}

}示例2: normalizeMethodName

}示例3: request
/**
* Performs any type of http request. First argument is required, and can either be a url or
* a {@link Request} instance. If the first argument is a url, an optional {@link RequestOptions}
* object can be provided as the 2nd argument. The options object will be merged with the values
* of {@link BaseRequestOptions} before performing the request.

/**
* whether this is querying for a variable binding or a directive.
