From e36c1c2aa15f97a08c7be87966e85e385c269cfe Mon Sep 17 00:00:00 2001 From: Jacob Hoffman-Andrews Date: Sat, 17 Oct 2020 00:40:48 -0700 Subject: [PATCH] Switch to Result-based API. (#132) Gets rid of synthetic_error, and makes the various send_* methods return `Result`. Introduces a new error type "HTTP", which represents an error due to status codes 4xx or 5xx. The HTTP error type contains a boxed Response, so users can read the actual response if they want. Adds an `error_for_status` setting to disable the functionality of treating 4xx and 5xx as errors. Adds .unwrap() to a lot of tests. Fixes #128. --- README.md | 5 +- examples/smoke-test/main.rs | 9 +-- src/agent.rs | 18 +++--- src/error.rs | 100 ++++++++++------------------------ src/lib.rs | 31 +++-------- src/request.rs | 73 +++++++++++++++++-------- src/response.rs | 106 +++++------------------------------- src/stream.rs | 2 + src/test/agent_test.rs | 40 +++++--------- src/test/auth.rs | 13 +++-- src/test/body_read.rs | 10 ++-- src/test/body_send.rs | 24 +++++--- src/test/query_string.rs | 10 ++-- src/test/range.rs | 3 +- src/test/redirect.rs | 26 ++++----- src/test/simple.rs | 26 ++++----- src/test/timeout.rs | 39 +++++++------ src/unit.rs | 10 ++-- tests/https-agent.rs | 21 ++----- 19 files changed, 222 insertions(+), 344 deletions(-) diff --git a/README.md b/README.md index 008e1d9..ee9948e 100644 --- a/README.md +++ b/README.md @@ -17,15 +17,12 @@ let resp = ureq::post("https://myapi.example.com/ingest") .send_json(serde_json::json!({ "name": "martin", "rust": true - })); + }))?; // .ok() tells if response is 200-299. if resp.ok() { println!("success: {}", resp.into_string()?); } else { - // This can include errors like failure to parse URL or - // connect timeout.
