//! A blocking Client API. //! //! The blocking `Client` will block the current thread to execute, instead //! of returning futures that need to be executed on a runtime. //! //! Conversely, the functionality in `reqwest::blocking` must *not* be executed //! within an async runtime, or it will panic when attempting to block. If //! calling directly from an async function, consider using an async //! [`reqwest::Client`][crate::Client] instead. If the immediate context is only //! synchronous, but a transitive caller is async, consider changing that caller //! to use [`tokio::task::spawn_blocking`] around the calls that need to block. //! //! # Optional //! //! This requires the optional `blocking` feature to be enabled. //! //! # Making a GET request //! //! For a single request, you can use the [`get`](get) shortcut method. //! //! ```rust //! # use reqwest::{Error, Response}; //! //! # fn run() -> Result<(), Error> { //! let body = reqwest::blocking::get("https://www.rust-lang.org")? //! .text()?; //! //! println!("body = {:?}", body); //! # Ok(()) //! # } //! ``` //! //! Additionally, the blocking [`Response`](Response) struct implements Rust's //! `Read` trait, so many useful standard library and third party crates will //! have convenience methods that take a `Response` anywhere `T: Read` is //! acceptable. //! //! **NOTE**: If you plan to perform multiple requests, it is best to create a //! [`Client`](Client) and reuse it, taking advantage of keep-alive connection //! pooling. //! //! # Making POST requests (or setting request bodies) //! //! There are several ways you can set the body of a request. The basic one is //! by using the `body()` method of a [`RequestBuilder`](RequestBuilder). This lets you set the //! exact raw bytes of what the body should be. It accepts various types, //! including `String`, `Vec`, and `File`. If you wish to pass a custom //! Reader, you can use the `reqwest::blocking::Body::new()` constructor. //! //! ```rust //! # use reqwest::Error; //! # //! # fn run() -> Result<(), Error> { //! let client = reqwest::blocking::Client::new(); //! let res = client.post("http://httpbin.org/post") //! .body("the exact body that is sent") //! .send()?; //! # Ok(()) //! # } //! ``` //! //! ## And More //! //! Most features available to the asynchronous `Client` are also available, //! on the blocking `Client`, see those docs for more. mod body; mod client; #[cfg(feature = "multipart")] pub mod multipart; mod request; mod response; mod wait; pub use self::body::Body; pub use self::client::{Client, ClientBuilder}; pub use self::request::{Request, RequestBuilder}; pub use self::response::Response; /// Shortcut method to quickly make a *blocking* `GET` request. /// /// **NOTE**: This function creates a new internal `Client` on each call, /// and so should not be used if making many requests.
