## Overview
|
|
|
|
Attach `TracingMiddleware` to your client to automatically trace HTTP requests:
|
|
|
|
```toml
|
|
# Cargo.toml
|
|
# ...
|
|
[dependencies]
|
|
opentelemetry = "0.17"
|
|
reqwest = "0.11"
|
|
reqwest-middleware = "0.1.1"
|
|
reqwest-retry = "0.1.1"
|
|
reqwest-tracing = { version = "0.1.2", features = ["opentelemetry_0_17"] }
|
|
tokio = { version = "1.12.0", features = ["macros", "rt-multi-thread"] }
|
|
tracing = "0.1"
|
|
tracing-opentelemetry = "0.15"
|
|
tracing-subscriber = "0.2"
|
|
```
|
|
|
|
```rust,skip
|
|
use opentelemetry::sdk::export::trace::stdout;
|
|
use reqwest_middleware::ClientBuilder;
|
|
use reqwest_tracing::TracingMiddleware;
|
|
use tracing_subscriber::layer::SubscriberExt;
|
|
use tracing_subscriber::Registry;
|
|
|
|
#[tokio::main]
|
|
async fn main() {
|
|
let tracer = stdout::new_pipeline().install_simple();
|
|
let telemetry = tracing_opentelemetry::layer().with_tracer(tracer);
|
|
let subscriber = Registry::default().with(telemetry);
|
|
tracing::subscriber::set_global_default(subscriber).unwrap();
|
|
|
|
run().await;
|
|
}
|
|
|
|
async fn run() {
|
|
let client = ClientBuilder::new(reqwest::Client::new())
|
|
.with(TracingMiddleware)
|
|
.build();
|
|
|
|
client.get("https://truelayer.com").send().await.unwrap();
|
|
}
|
|
```
|
|
|
|
```terminal
|
|
$ cargo run
|
|
SpanData { span_context: SpanContext { trace_id: ...
|
|
```
|
|
|
|
See the [`tracing`](https://crates.io/crates/tracing) crate for more information on how to set up a
|
|
tracing subscriber to make use of the spans.

|
|
## How to install
|
|
|
|
Add `reqwest-tracing` to your dependencies. Optionally enable opentelemetry integration by enabling
|
|
an opentelemetry version feature:
|
|
|
|
```toml
|
|
[dependencies]
|
|
# ...
|
|
reqwest-tracing = { version = "0.1.0", features = ["opentelemetry_0_17"] }
|
|
```
|
|
|
|
Available opentelemetry features are `opentelemetry_0_17`, `opentelemetry_0_16`, `opentelemetry_0_15`, `opentelemetry_0_14` and
|
|
`opentelemetry_0_13`.
