reqwest provides an easy way of sending JSON-formatted body in the HTTP request and
it always emits terse on-line JSON representation.
Most of the time it is exactly what you need. However, in some cases you may prefer to emit “pretty” JSON representation of your data structures. Key-Value data stores are one such use case and there may be others as well.
In this case you won’t be able to use [
reqwest::RequestBuilder.json] method and will have to
manually serialize your data and set both the body of the request and Content-Type HTTP header.
This crate provides convenient method to do just that.
It exports trait
PrettyJson that extends
PrettyJson::pretty_json method (in addition to the original
use reqwest::Client; use reqwest_pretty_json::PrettyJson; let data = vec![1, 2, 3]; let client = Client::new(); let request = client .post("http://httpbin.org/post") .pretty_json(&data) .build();
A trait to set HTTP request body to a “prettified” JSON-formatted representation of the data.
