What Are MIME Types?

A Multi-Purpose Internet Mail Extension (eg. “application/octet-stream”), also known as a MIME, is type of Internet standard originally developed to allow the exchange of different types of data files through e-mail messages. MIME types like application/octet-stream are classified into specific data categories such as Video, Audio, Image, and many more. This categorization provides instructions to your computer or mobile device about how these files should be opened / viewed.

Why Do I Need MIME Types Like application/octet-stream?

Categorizing MIME types like application/octet-stream into a data type such as “Application” allows your e-mail client or Internet browser to display the content as intended. For example, when you attach a digital camera photo file to an e-mail, an Image MIME type will be associated with that file to allow your recipient to view the photograph.

Here's how it works: Web servers (computers that host websites and e-mail) insert a set of MIME instructions into the beginning of a data transmission, such as an e-mail message or webpage, in the following format:

Content-Type: application/octet-stream

[Format Explanation: The MIME type, which in this example is “Application”, is separated by a forward slash (“/”) and followed by a subtype.]

This set of instructions tells your client application, such as an e-mail program (eg. Microsoft Outlook, Apple Mail) or web browser (eg. Google Chrome, Mozilla Firefox), which “player application” should be used to properly display the application/octet-stream content.

Many modern web browsers include built-in components to display common data types such as image players (eg. GIF, JPEG), Adobe Flash Player, Javascript, and many more. Other less-common types of players must be downloaded separately in order to properly display the MIME content.

What Are The Most Common Problems Associated With application/octet-stream?

Sometimes you’ll find that your web browser or e-mail client is unable to properly display your application/octet-stream content. This could be due to one of two reasons:

1. You are missing the proper Application “player software” to display the application/octet-stream content.

2. Your Windows Registry contains an incorrect file extension (eg. XLS, PDF) association with the application/octet-stream MIME type.

How To Fix application/octet-stream Issues

Do I have the application/octet-stream “player application” installed?

The first step in troubleshooting issues with opening application/octet-stream content is to first make sure that you have the correct “player application” installed for this MIME type. Because there can be several (or even hundreds) of related software applications to application/octet-stream, it is very difficult for us to compile a comprehensive list.

Therefore, a key strategy in determining the correct application is to look for clues on what software programs might be related to application/octet-stream. Look at the naming of the subtype for clues about a related program (eg. Word, Excel) or software developer name (eg. Microsoft).

Furthermore, if you’ve been sent MIME type application/octet-stream as an e-mail attachment, look for the file extension of the attached file. This file extension (eg. PKG, LHA, LZH, etc.) can provide you with a clue of what “player application” is associated with this Application MIME. Take a look at our file extension list below to see if there are any clues to finding the right “player application”.

Do I have broken application/octet-stream file associations?

The second step in troubleshooting application/octet-stream issues is making sure that you have correct file associations in the Windows Registry. Installing and uninstalling programs can lead to incorrect file associations with application/octet-stream. Take a look at your Windows Registry settings to ensure that the MIME type is correctly associated with the “player application” and file extension.

WARNING: DO NOT edit the Windows Registry unless you are an advanced computer user with experience editing the Registry. Making an error in editing the Registry can create irreversible damage to your PC.

If you are not comfortable editing the Windows Registry, we highly recommend using an automated registry cleaning program, or taking you computer to a qualified professional.

Various content types can flow through a logic app,for example, JSON, XML, flat files, and binary data.While Logic Apps supports all content types, some have nativesupport and don't require casting or conversion in your logic apps.Other types might require casting or conversion as necessary.This article describes how Logic Apps handles content types andhow you can correctly cast or convert these types when necessary.

To determine the appropriate way for handling content types,Logic Apps relies on the Content-Type header value in HTTP calls,for example:

  • application/json (native type)
  • text/plain (native type)

application/json

Logic Apps stores and handles any request with the application/jsoncontent type as a JavaScript Notation (JSON) object.By default, you can parse JSON content without any casting.To parse a request that has a header with the 'application/json' content type,you can use an expression. This example returns the value dog from theanimal-type array without casting:

@body('myAction')['animal-type'][0]

If you're working with JSON data that doesn't specify a header,you can manually cast that data to JSON by using thejson() function,for example:

@json(triggerBody())['animal-type']

Create tokens for JSON properties

Logic Apps provides the capability for you to generate user-friendlytokens that represent the properties in JSON content so you canreference and use those properties more easily in your logic app's workflow.

  • Request trigger

    When you use this trigger in the Logic App Designer, you can providea JSON schema that describes the payload you expect to receive.The designer parses JSON content by using this schema and generatesuser-friendly tokens that represent the properties in your JSON content.You can then easily reference and use those properties throughout yourlogic app's workflow.

The free version should not be time limited, i.e. You should be able to use the software indefinitely without needing to pay for it.

    If you don't have a schema, you can generate the schema.

    1. In the Request trigger, select Use sample payload to generate schema.

    2. Under Enter or paste a sample JSON payload, provide a sample payloadand then choose Done. For example:

      The generated schema now appears in your trigger.

    3. In your request, make sure you include a Content-Type headerand set the header's value to application/json.

  • Parse JSON action

    When you use this action in the Logic App Designer,you can parse JSON output and generate user-friendlytokens that represent the properties in your JSON content.You can then easily reference and use those propertiesthroughout your logic app's workflow. Similar tothe Request trigger, you can provide or generate aJSON schema that describes the JSON content you want to parse.That way, you can more easily consume data from Azure Service Bus,Azure Cosmos DB, and so on.

text/plain

When your logic app receives HTTP messages thathave the Content-Type header set to text/plain,your logic app stores those messages in raw form.If you include these messages in subsequent actions without casting,requests go out with the Content-Type header set to text/plain.

For example, when you're working with a flat file,you might get an HTTP request with the Content-Typeheader set to text/plain content type:

Date,Name,Address
Oct-1,Frank,123 Ave

If you then send this request on in a later action as the body for another request,for example, @body('flatfile'), that second request also has a Content-Typeheader that's set to text/plain. If you're working with data that is plain textbut didn't specify a header, you can manually cast that data to text by using thestring() functionsuch as this expression:

@string(triggerBody())

application/xml and application/octet-stream

Logic Apps always preserves the Content-Type in a received HTTP request or response.So if your logic app receives content with Content-Type set to application/octet-stream,and you include that content in a later action without casting,the outgoing request also has Content-Type set to application/octet-stream.That way, Logic Apps can guarantee that data doesn't get lost while moving through the workflow.However, the action state, or inputs and outputs, is stored in a JSON objectwhile the state moves through the workflow.

Converter functions

To preserve some data types, Logic Apps converts content to a binarybase64-encoded string with appropriate metadata that preserves boththe $content payload and the $content-type, which are automatically converted.

This list describes how Logic Apps converts content when you use thesefunctions:

  • json(): Casts data to application/json
  • xml(): Casts data to application/xml
  • binary(): Casts data to application/octet-stream
  • string(): Casts data to text/plain
  • base64(): Converts content to a base64 string
  • base64toString(): Converts a base64 encoded string to text/plain
  • base64toBinary(): Converts a base64 encoded string to application/octet-stream
  • encodeDataUri(): Encodes a string as a dataUri byte array
  • decodeDataUri(): Decodes a dataUri into a byte array

For example, if you receive an HTTP requestwhere Content-Type set to application/xml,such as this content:

You can cast this content by using the @xml(triggerBody())expression with the xml() and triggerBody() functionsand then use this content later. Or, you can use the@xpath(xml(triggerBody()), '/CustomerName') expressionwith the xpath() and xml() functions.

Other content types

Logic Apps works with and supports other content types,but might require that you manually get the messagebody by decoding the $content variable.

For example, suppose your logic app gets triggered by a requestwith the application/x-www-url-formencoded content type.To preserve all the data, the $content variable in therequest body has a payload that's encoded as a base64 string:

CustomerName=Frank&Address=123+Avenue

Because the request isn't plain text or JSON,the request is stored in the action as follows:

Logic Apps provides native functions for handling form data, for example:

Or, you can manually access the data by using an expression such as this example:

@string(body('formdataAction'))

If you wanted the outgoing request to have the sameapplication/x-www-url-formencoded content type header,you can add the request to the action's body withoutany casting by using an expression such as @body('formdataAction').However, this method only works when the body is the onlyparameter in the body input. If you try to use the@body('formdataAction') expression in an application/json request,you get a runtime error because the body is sent encoded.
