Also, remove Response::{ok, error, client_error, server_error,
redirect}. The idea is that you would access these through the
Error object instead.
I fetched all the reverse dependencies of ureq on crates.io and looked
for uses of the methods being removed. I found none.
I'm also considering removing the error_on_non_2xx method entirely. If
it's easy to get the underlying response for errors, it would be nice to
make that the single way to do things rather than support two separate
ways of handling HTTP errors.
This adds a source field to keep track of upstream errors and allow
backtraces, plus a URL field to indicate what URL an error was
associated with.
The enum variants we used to use for Error are now part of a new
ErrorKind type. For convenience within ureq, ErrorKinds can be turned
into an Error with `.new()` or `.msg("some additional information")`.
Error acts as a builder, so additional information can be added after
initial construction. For instance, we return a DnsFailed error when
name resolution fails. When that error bubbles up to Request's
`do_call`, Request adds the URL.
Fixes#232.
Instead, rely on Url's built-in query parameter handling. A Request now
accumulates a list of query param pairs, and joins them with a parsed
URL at the time do_call is called.
In the process, remove some getters that rely on parsing the URL.
Adapting these getters was going to be awkward, and they mostly
duplicate things people can readily get by parsing the URL.
* Remove Request::build
* All mutations on Request follow builder pattern
The previous `build()` on request was necessary because mutating
functions did not follow a proper builder pattern (taking `&mut self`
instead of `mut self`). With a proper builder pattern, the need for
`.build()` goes away.
* All Request body and call methods consume self
Anything which "executes" the request will now consume the `Request`
to produce a `Result<Response>`.
* Move all config from request to agent builder
Timeouts, redirect config, proxy settings and TLS config are now on
`AgentBuilder`.
* Rename max_pool_connections -> max_idle_connections
* Rename max_pool_connections_per_host -> max_idle_connections_per_host
Consistent internal and external naming.
* Introduce new AgentConfig for static config created by builder.
`Agent` can be seen as having two parts. Static config and a mutable
shared state between all states. The static config goes into
`AgentConfig` and the mutable shared state into `AgentState`.
* Replace all use of `Default` for `new`.
Deriving or implementing `Default` makes for a secondary instantiation
API. It is useful in some cases, but gets very confusing when there
is both `new` _and_ a `Default`. It's especially devious for derived
values where a reasonable default is not `0`, `false` or `None`.
* Remove feature native_tls, we want only native rustls.
This feature made for very clunky handling throughout the code. From a
security point of view, it's better to stick with one single TLS API.
Rustls recently got an official audit (very positive).
https://github.com/ctz/rustls/tree/master/audit
Rustls deliberately omits support for older, insecure TLS such as TLS
1.1 or RC4. This might be a problem for a user of ureq, but on balance
not considered important enough to keep native_tls.
* Remove auth and support for basic auth.
The API just wasn't enough. A future reintroduction should at least
also provide a `Bearer` mechanism and possibly more.
* Rename jar -> cookie_store
* Rename jar -> cookie_tin
Just make some field names sync up with the type.
* Drop "cookies" as default feature
The need for handling cookies is probably rare, let's not enable it by
default.
* Change all feature checks for "cookie" to "cookies"
The outward facing feature is "cookies" and I think it's better form
that the code uses the official feature name instead of the optional
library "cookies".
* Keep `set` on Agent level as well as AgentBuilder.
The idea is that an auth exchange might result in a header that need
to be set _after_ the agent has been built.
This adds validation of header values on receive, and of both header
names and header values on send. This doesn't change the return
type of set to be a Result, it just validates when the request is
sent. Also removes the section in the README describing handling
of invalid headers, and updates a test that verified acceptance of
non-ASCII headers so that it verifies rejection of them instead.
Gets rid of synthetic_error, and makes the various send_* methods return `Result<Response, Error>`.
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.
This removes the necessity to take the result of Response::into_json and
having to convert it into a struct by using serde_json::from_value
This adds no new dependencies since serde_json already depends on serde.
Users of ureq will have to include `serde_derive` either by importing it
directly or by using serde with the `derive` feature, unless they want to
manually implement `Deserialize` on their structs.
