As of Feb 11th 2020, request is fully deprecated. No new adjustments are anticipated to land. In actual fact, none have landed for a while. For more details about why request is deprecated and possible alternatives consult with this difficulty. Request is designed to be the only means possible to make http calls. It supports HTTPS and follows redirects by default. You can stream any response to a file stream. You can even stream a file to a PUT or Post request.
This methodology can even examine the file extension towards a mapping of file extensions to content-types (on this case application/json) and use the correct content-sort within the PUT request (if the headers don’t already provide one). Request also can pipe to itself. When doing so, content material-sort and content material-length are preserved within the PUT headers. Request emits a “response” occasion when a response is acquired.
The response argument will be an occasion of http.IncomingMessage. Now let’s get fancy. You can even pipe() from http.ServerRequest situations, as well as to http.ServerResponse instances.
The HTTP methodology, headers, and entity-body knowledge will probably be despatched. And since pipe() returns the vacation spot stream in ≥ Node 0.5.x you are able to do one line proxying. Additionally, none of this new performance conflicts with requests previous features, it just expands them.
If you’d like request to return a Promise as an alternative, you should utilize an alternate interface wrapper for request. These wrappers might be helpful if you happen to choose to work with Guarantees, or if you’d like to make use of async/await in ES2017. Additionally, util.promisify, which is available from Node.js v8.Zero can be utilized to convert a daily function that takes a callback to return a promise instead. For multipart/associated consult with the multipart API.
URL-encoded kinds are easy. For multipart/form-information we use the form-knowledge library by @felixge. For the most instances, you can go your add form knowledge by way of the formData option. For google:suggestsubtypes advanced instances, you possibly can entry the kind-information object itself by way of r.form(). This may be modified until the request is fired on the next cycle of the event-loop.
See the form-data README for extra info & examples.
Some variations in numerous HTTP implementations require a newline/CRLF before, after, or each earlier than and after the boundary of a multipart/related request (using the multipart possibility). This has been observed within the .Internet WebAPI model 4.0. You possibly can activate a boundary preambleCRLF or postamble by passing them as true to your request choices. The strategy form takes parameters auth(username, password, sendImmediately, bearer). Instantly defaults to true, which causes a primary or bearer authentication header to be despatched.
If sendImmediately is false, then request crypto markets will crash retry with a proper authentication header after receiving a 401 response from the server (which should include a WWW-Authenticate header indicating the required authentication methodology). Digest authentication is supported, nevertheless it only works with sendImmediately set to false; in any other case request will send primary authentication on the preliminary request, which is able to in all probability trigger the request to fail.
