I'm Pascal, I have a PHP background and have started to learn Rust for a few months.
As first small project I would like to create a small library which can communicate with a web service.
For some purpose I need to send a file in a multipart form.
As there is a lot of libraries which can help me to do this I have chosen to give a try to reqwest.
I don't find in the documentation an example of how I can implement this and it's difficult for me to have a picture how I can process.
I have already written this library in PHP therefore I thought this could be the best way for me to start learning.
Is there is an 'officiel' library to use for this like 'rand' is?
Can I use httpmock to test my request or something else?
There's no official library for http, but reqwest is definitely the most widely used library out there for this purpose.
You can find an example on this page. I have included it below:
use reqwest::blocking::multipart;
let form = multipart::Form::new()
// Adding just a simple text field...
.text("username", "seanmonstar")
// And a file...
.file("photo", "/path/to/photo.png")?;
// Customize all the details of a Part if needed...
let bio = multipart::Part::text("hallo peeps")
.file_name("bio.txt")
.mime_str("text/plain")?;
// Add the custom part to our form...
let form = form.part("biography", bio);
// And finally, send the form
let client = reqwest::blocking::Client::new();
let resp = client
.post("http://localhost:8080/user")
.multipart(form)
.send()?;
Be aware that reqwest is split into a blocking an async version. The above example is from the blocking version of reqwest, which is found under the reqwest::blocking module. The documentation link that you have in your post links to the async version, which is why it looks different. I used the blocking version because it didn't sound like you had a use-case where async makes sense.
