Download json and binary file in one request

 · Submit a POST that contains JSON data to a REST url. If the request specifies a JSON response, then JSON is returned. If the request specifies a PDF/XLS/etc response, then a downloadable binary is returned. I have 1 2 working now, and the client jquery app displays the returned data in the web page by creating DOM elements based on the JSON bltadwin.rus: 3. The response property will contain the entity body according to responseType, as an ArrayBuffer, Blob, Document, JSON, or string. This is null if the request is not complete or was not successful. This example reads an image as a binary file and creates an 8-bit unsigned integer array from the raw bytes.  · And I didn't found a strait forward and simple tutorial to handle binary files with json. So I decided to write one. Please share your comments and suggestions so I .

If I wanted to download content from a website and have the tree-structure of the website searched recursively for that content, I'd use wget. If I wanted to interact with a remote server or API, and possibly download some files or web pages, I'd use curl. Especially if the protocol was one of the many not supported by wget. bltadwin.ru (fp, *, cls = None, object_hook = None, parse_float = None, parse_int = None, parse_constant = None, object_pairs_hook = None, ** kw) ¶ Deserialize fp (bltadwin.ru()-supporting text file or binary file containing a JSON document) to a Python object using this conversion table.. object_hook is an optional function that will be called with the result of any object literal decoded (a dict). You describe individual parts of the request as properties of the schema object. As you can see, a multipart request can include various data: strings, objects in JSON format, and binary data. You can also specify one or several files for uploading. (To learn more, see File Upload.) The example above corresponds to the following request.

EDIT: After reviewing the docs for $.ajax, I see that the response dataType can only be one of xml, html, script, json, jsonp, text, so I’m guessing there is no way to directly download a file using an ajax request, unless I embed the binary file in using Data URI scheme as suggested in the @VinayC answer (which is not something I want to do). 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: JSON / XML. Probably the easiest and most compatible way to send the data is to serialize it to JSON or XML. Also the binary data, which means getting +33% in message size due to BASE64 compression. This may be just fine in. You describe individual parts of the request as properties of the schema object.
