![]() ![]() Consumer secret (private information of your app provided by Twitter).Consumer key (private information of your app provided by Twitter).Then the global parameters related to OAuth: URL target of your HTTP request (example: ).Method of your HTTP request (example: GET).First the parameters directly linked to your request: Here is the list of the needed parameters. ![]() This string will be the value associated to “Authorization” key in HTTP header properties. The global idea is: you have a lot of input parameters and you must follow the specifications to construct a string based on the parameters. It lets you play around and gives great insights on each request to debug your own implementation of OAuth protocol. But in the case of the Twitter API, you have a nice documentation here.īesides on the documentation of each method, you have an OAuth Signature Generator that can be accessed (if you have defined a Twitter App). The official specification for 1.0A can be read here. The thing is you need to identify yourself when sending the request. So far it seems really easy to do with a simple InvokeHTTP processor. The objective was to request the “users/lookup” method of the Twitter API. Some modifications may be necessary for some cases. Note 2: I didn’t test the flow on a lot of methods. Note 1: this was the first time I used Groovy language, be nice with me! It gives me the opportunity to use for the first time the ExecuteScript processor which allows user to execute custom scripts on the fly inside NiFi (you will find a lot of examples on this great site). This post presents the flow I used to perform a request against Twitter API using OAuth protocol. So this time, I decided to have a look on this and to get the job done. Recently, a question was asked on the Hortonworks Community Connection regarding the use of Apache NiFi to get data from Twitter API using OAuth 1.0A protocol. I already faced the need to use OAuth 1.0A protocol with the Flickr API but, back then, I found a way to get my data differently. As far as I know, 1.0A is the most commonly used. ![]() The third party then uses the access token to access the protected resources hosted by the resource server.Īs a remark, there are two versions of the protocol currently used out there: 1.0A and 2.0. Designed specifically to work with Hypertext Transfer Protocol (HTTP), OAuth essentially allows access tokens to be issued to third-party clients by an authorization server, with the approval of the resource owner. It specifies a process for resource owners to authorize third-party access to their server resources without sharing their credentials. Generally, OAuth provides to clients a “secure delegated access” to server resources on behalf of a resource owner. accounts without exposing their password. OAuth is an open standard for authorization, commonly used as a way for Internet users to log into third party websites using their Microsoft, Google, Facebook, Twitter, One Network etc. You can find the Terminal app in the Launchpad > Other folder, or by searching for Terminal in Spotlight, which you can access by clicking the search icon in the top menu bar.A lot of API are using OAuth protocol to authorize the received requests and to check if everything is OK regarding the identity of the request sender. To install Homebrew, start by opening up a macOS Terminal app window.This might be useful to install multiple apps to new macOS devices, for instance. It allows you to install apps using the macOS terminal, either individually, or using it to create a bulk installer to install multiple apps at once. Homebrew acts as a package manager in the same way that APT does on Linux. This is a double-edged sword, as while you’ll be able to install unverified apps, you’ll need to ensure that you only install apps and software that you trust. The benefit of using Homebrew to install macOS apps is that it bypasses the security mechanisms that Apple uses to “protect” you from unverified apps. While Apple would prefer you to install apps through the App Store, you can bypass it completely with Homebrew. Using Homebrew To Run Unverified Apps on Mac As it won’t be installed on your system, you’ll need to repeat this process to launch it again once you close it. ![]()
