headers = {'Content-Type': 'application/x-www-form-urlencoded'} response = get-point.ru(endpoint, data=request_body, headers=headers). 4) The x-www-form-urlencoded is used more generally to send text data to the server while multipart/form-data is used to send binary data, most. The application/x-www-form-urlencoded content type describes form data that is sent in a single block in the HTTP message body. Unlike the query part of the.

Is there any additional guidance when to use one of the encoding types in an API context no browser involved? This might e. I basically found no formal guidance on the web regarding the use of the different content-types so far. Depending on the type and amount of data being transmitted, one of the methods will be more efficient than the other.

To understand why, you have to look at what each is doing under the covers. An example of this would be:. According to the specification :. That means that for each non-alphanumeric byte that exists in one of our values, it's going to take three bytes to represent it.

For large binary files, tripling the payload is going to be highly inefficient. Parts are separated by a particular string boundary chosen specifically so that this boundary string does not occur in any of the "value" payloads. The MIME spec gives us more options when representing the value payload -- we can choose a more efficient encoding of binary data to save bandwidth e.

For short alphanumeric values like most web forms , the overhead of adding all of the MIME headers is going to significantly outweigh any savings from more efficient binary encoding. I know this is 3 years too late, but Matt's accepted answer is incomplete and will eventually get you into trouble. If you don't choose your boundary correctly, then you will eventually have a problem, whether you're sending plain text or raw binary - the server will find a boundary in the wrong place, and your file will be truncated, or the POST will fail.

The key is to choose an encoding and a boundary such that your selected boundary characters cannot appear in the encoded output. One simple solution is to use base64 do not use raw binary. Many choices you see on the net fail this test - the MDN forms docs , for example, use "blob" as a boundary when sending binary data - not good. However, something like "!

This is also the case for typical HTML representation based webapps e. It adds another call but decouples stuff better. Example images:. If you get a clear idea of your users, and how they'll make use of your API, then that will help you decide. If you make the upload of files hard for your API users then they'll move away, of you'll spend a lot of time on supporting them.

Secondary to this would be the tool support YOU have for writing your API and how easy it is for your to accommodate one upload mechanism over the other. I am working on a project for a print-shop and had some problems due to uploading images to the server that came from an HTML5 canvas element. I was struggling for at least an hour and I did not get it to save the image correctly on my server. Use IFormCollection instead:.

Please do not us base64 encoding to accomplish this. A boundary which is randomly generated and the same length as a UUID should be sufficient: stackoverflow. EML, This doesn't make sense at all. Obviously the boundary is chosen automatically by the http client browser and the client will be smart enough not to use a boundary that clashes with the contents of your uploaded files.

Pacerier: A read the question: "no browser involved, API context". B browsers don't construct requests for you anyway. You do it yourself, manually. There's no magic in browsers. EML's suggestion convert to base64 just to avoid matching substrings is just plain odd, not to mention it comes with unneeded performance degradation.

And all the trouble for nothing since the one line algorithm is equally straightforward and simple. Base64 is not meant to be ab used this way, as HTTP body accept all 8-bit octets. This answer not only adds nothing to the discussion, but also gives wrong advice. Firstly, whenever transmitting random data in separated parts, it is always possible that the chosen boundary will be present in the payload.

The ONLY way to make sure this doesn't happen is to examine the entire payload for each boundary we come up with. Completely impractical. Secondly, always using Base64 will waste bandwidth and fill up buffers for no reason at all. Show 11 more comments. I use it for "normal" webforms.

Joe Shaw Martin Peck Martin Peck Hi, does it mean that every time we post somethings to web server, we have to mention what is the Content-type in order to let web server know should it decode the data?

GMsoF, It's optional. See stackoverflow. You may want to avoid using content-type when crafting a specific request for a specific server to avoid generic overheads. Just a little hint from my side for uploading HTML5 canvas image data: I am working on a project for a print-shop and had some problems due to uploading images to the server that came from an HTML5 canvas element.

What content type was it sending it before you changed it? This problem could have been due to the server not supporting the content type you were sending it as. This is bad and might result in security issues. Unescaped text is added into a format with defined encoding.

I'm going to dig into the right way, but also take a stroll around some related, lesser-known APIs:. It's pretty handy, because, well…. In particular, readers are cautioned to pay close attention to the twisted details involving repeated and in some cases nested conversions between character encodings and byte sequences. Unfortunately the format is in widespread use due to the prevalence of HTML forms.

There are multiple methods to read and mutate URLSearchParams , which are documented on MDN , but if you want to handle all the data then its iterator comes in handy:. Unfortunately, location. This is because the definition for window. For instance setting otherWindow. Anyway, to work around it:. Ok, now we're getting to the point. The code in the example at the start of the article is broken as it isn't escaping the input:.

To make things easier, URLSearchParams can be used directly as a Request or Response body, so the 'correct' version of the code from the start of the article is:. You can still provide your own Content-Type header to override the default.

This gives you the data that would be submitted by the form. I often find this much easier than getting the data from each element individually. However, this conversion will throw if the form data contains a file.
