You can map each response header to a data field, and the response body can be stored in either a text field or a file field. The web request node also lets you specify how to handle the web response that you get back from the server. Other authentication schemes are often possible through custom HTTP headers. When it comes to security, WEM supports basic authentication and client certificates out of the box. This can either be plain text (for instance, json or xml) or a document such as an image or a pdf file. This way WEM will take care of proper url encoding. Query fields – You can manually put the queryfields in the url yourself, but I recommend to specify them separately.You can specify any number of additional headers. Request headers – The header fields Accept, Connection and Content-Type are predefined.The request method ( GET and POST are the most common methods, but WEM supports all common methods).The url (this includes the scheme, which is either http or https).When you drag this node in your flowchart, you can specify all the aspects that make up an HTTP request message: We recently added a new node type to the flowchart editor that can perform any HTTP web request, and conveniently called it the “ web request node“. Your browser sends an HTTP request to a web server any time you request a new web page, while webservers use HTTP to communicate with each other through webservices. HTTP (Hypertext Transfer Protocol) is the protocol that is used to communicate with web servers. The second part will focus on JSON messages and how to handle them in WEM. This part of this article explores a new feature in WEM that allows you to perform any HTTP web request. You can already see the final application working at. At the end of this article we will have built a simple application that uses the Open Movie Database API to search for a movie and show the details. This article explains how to consume a JSON webservice from within your WEM project.
