a message consists of a series of parts.multipart/form-data conforms to standard multipart MIME data streams as outlined in RFC2045. The HTML specification does a decent job of explaining the rules. The first pieces specifies that our request was submitted as multipart/form-data and the boundary is what is used to separate the "multiple parts" of the multipart request body. You'll see that this contains two pieces of information: The most interesting piece of the headers 'content-type': 'multipart/form-data boundary=-WebKitFormBoundaryvlb7BC9EAvfLB2q5', 'content-type': 'multipart/form-data boundary=-WebKitFormBoundaryvlb7BC9EAvfLB2q5', The headers will look similar to below: host: 'localhost:8080', The server will log the headers and the content. The content type "application/x-So there you have it, use form-data when sending data that:īut what does a multipart request look like? Using our buddy Postman, we'll submit a request that uses form-data like this: The W3C provides some guidance on when it is appropriate to use this encoding type: The form data that was submitted is URL encoded, just as if it was in a query string: username=brian+mancini&nickname=turkey%24Īs we mentioned previously, the other encoding content-type is multipart/form-data. More interestingly, and more pertinent to this discussion is the actual request body submitted to the server. The content-type is our old friend application/x-www-form-urlencoded. The content-length relates to the length of transmitted data. The important ones here are the content-length and content-type headers. 'content-type': 'application/x-www-form-urlencoded', The server outputs the following headers in the request: host: 'localhost:8080', In the example below, two fields are submitted via a Postman request that looks like

Lets take a look at what a full request would look like from the server's perspective. X-www-form-urlencoded requests will also have an HTTP header specified for Content-Type with a value of application/x-www-form-urlencoded. In the URL, it is encoded to make a valid URL. You can see the q=c%23+multipart/form-data is the actual name/value pair for the query. If you type "C# multipart/form-data" into Google the URL you navigate to is. URL encoding is something you've undoubtedly seen before. X-It involves URL encoding the name and values pairs according to the rules outline in the HTML specification. Using Postman we can submit requests with various encoding types and form data.

The above code simply creates an endpoint at /raw and will log the headers and request body to stdout. Setupīefore we dive into the specifics, let's create a simple Express app that will output the headers and content of a request so we can see exactly what a request looks like: So, functionally, the content type is specifying that the keys and values submitted in a form will be encoded in a specific format. The enctype attribute of the FORM element specifies the content type used to encode the form data set for submission to the server. We often switch to multipart/form-data where we need to upload a file: īy what do the encoding content types do? They are typically added to the enctype property on a FORM HTML element.Īs a developer, chances are pretty good that you've seen them and worked with them:īy default, application/x-www-form-urlencoded is used to submit standard form field. The encoding content types are defined in the W3C HTML Specification.

So lets back up and first discuss the encoding content types. yet it is undeniable that a web developer should have working knowledge of these content types. In all my years, I don't think I've had someone mention the content type of the encoding for form data. Most candidates understand that GET is used for requesting information and uses the query string, while POST is used for submitting data and data is submitted via form data. In tech interviews, I often ask candidates to explain the difference between the GET and POST HTTP verbs. After running through various scenarios to optimize throughput of these services we landed on using multipart/form-data to transmit data between our services. …so yeah, it's a bad idea to try and encode/decode it yourself.I was recently working on a project that involved sending large amounts of data through a series of HTTP based web service. The application/x-Unfortunately the format is in widespread use due to the prevalence of HTML forms.- The URL standard URLSearchParams handles encoding and decoding application/x-www-form-urlencoded data. I'm going to dig into the right way, but also take a stroll around some related, lesser-known APIs: URLSearchParams

It's similar to SQL/HTML injection, as something intended as a 'value' gets to interact with the format directly. Unescaped text is added into a format with defined encoding.
