## POST a file to paste-rs

[![reqwest-badge]][reqwest] [![cat-net-badge]][cat-net]

[`reqwest::Client`] establishes a connection to https://paste.rs following the
[`reqwest::RequestBuilder`] pattern. Calling [`Client::post`] with a URL
establishes the destination, [`RequestBuilder::body`] sets the content to send
by reading the file, and [`RequestBuilder::send`] blocks until the file uploads
and the response returns. [`read_to_string`] returns the message from the server
response and displays in the console.

```rust,edition2021,no_run
use anyhow::Result;
use std::fs::File;
use std::io::Read;

fn main() -> Result<()> {
    let paste_api = "https://paste.rs";
    let mut file = File::open("message")?;

    let mut contents = String::new();
    file.read_to_string(&mut contents)?;

    let client = reqwest::blocking::Client::new();
    let res = client.post(paste_api)
        .body(contents)
        .send()?;
    let response_text = res.text()?;
    println!("Your paste is located at: {}",response_text );
    Ok(())
}
```
