Simple, minimal-dependency HTTP client. Optional features for json responses (json-using-serde), unicode domains (punycode), http proxies (proxy), and https with various TLS implementations (https-rustls, https-rustls-probe, https-bundled, https-bundled-probe,https-native, and https which is an alias for https-rustls).

Without any optional features, my casual testing indicates about 100 KB additional executable size for stripped release builds using this crate. Compiled with rustc 1.45.2, println!("Hello, World!"); is 239 KB on my machine, where the hello example is 347 KB. Both are pure Rust, so aside from libc, everything is statically linked.

Note: some of the dependencies of this crate (especially serde and the various https libraries) are a lot more complicated than this library, and their impact on executable size reflects that.

This is a list of features I'll implement once it gets long enough, or a severe enough issue is found that there's good reason to make a major version bump.

• Change the response/request structs to allow multiple headers with the same name.
• Set sane defaults for maximum header size and status line length. The ability to add maximums was added in response to #55, but defaults for the limits is a breaking change.
• Clearer error when making a request to an url that does not start with http:// or https://.
• Non-exhaustive error type?
• Change default proxy port to 1080 (from 8080). Curl uses 1080, so it's a sane default.
• Bump MSRV enough to compile the latest versions of all dependencies, and add the rust-version (at least 1.56) and edition (at least 2021) fields to Cargo.toml.

If you don't care about the MSRV, you can ignore this section entirely, including the commands instructed.

We use an MSRV per major release, i.e., with a new major release we reserve the right to change the MSRV.

The current major version (v2) of this library should always compile with any combination of features excluding the TLS and urlencoding features on Rust 1.48. This is because those dependencies themselves have a higher MSRV.

That said, the crate does still require forcing some dependencies to lower-than-latest versions to actually compile with the older compiler, as these dependencies have upped their MSRV in a patch version. This can be achieved with the following (these just update your Cargo.lock):

cargo update --package=log --precise=0.4.18

# only required if you're using the `json-using-serde` feature:
cargo update --package=serde_json --precise=1.0.100

# only required if you're testing minreq, as this is a dependency of the dev-dependency `tiny_http`:
cargo update --package=chrono --precise=0.4.23
