Display a byte image from a REST web service This tutorial will not delve into angular nor will we discuss what a directive is. Instead we will provide a demonstration via actual code, how we can consume a rest service from angular that returns an array of byte and display it as an image. We will also provide a default image in case the web service fails to return a valid image.
There are many ways to do it, but I chose a directive because of its simplicity.Project diva f 2nd save data rpcs3
Handle it accordingly. What it does is it accepts an id and imageType as parameters. We use the id to get the image from the rest service; imageType is used to construct different url depending on its value. This is so we can reused this directive.

Related The problem I would like to discuss is an API call, where you need to send binary data for example multiple images and some metadata information together. There are various ways you can approach this, and I will describe them briefly. This enables the client to upload some initial files, then later add some more.
This could be a good approach if you are creating a new photo album metadatathen adding photos to it. There are some cases however when metadata and files are one entity and neither makes sense on its own. In this scenario you want to take some action on the whole client request data right away. If you used approach 1 in this scenario, you need to manage state between client requests.
This can be complex and may hurt your scalability. Fortunately you can send all data in one request if this is what makes the most sense. Here are a few ways to do this:.
This may be just fine in some cases. However if the extra message size is not something you can put up with, then you can use a form of binary serialization. With ASP. On the client side, you can use JSON.

NET to do the serialization of the request message. In those cases you can still avoid sending binary data in BASE64 encoded string.

NET type and back. Then in CanRead and CanWrite you specify. NET types, to which or from which the request can be translated. ReadFromStreamAsync does the actual work. Decoupling controller logic from request parsing logic gives you possibility to handle multiple request formats and you can let your clients choose the format they are most comfortable with by specifying appropriate Content-Type header.
Note: when you do the content. How about some client code?How to create RESTFUL API in JSON format using JAVA
