Struct reqwest::RedirectPolicy

pub struct RedirectPolicy { /* fields omitted */ }

A type that controls the policy on how to handle the following of redirects.

The default value will catch redirect loops, and has a maximum of 10 redirects it will follow in a chain before returning an error.

Methods

impl RedirectPolicy

fn limited(max: usize) -> RedirectPolicy

Create a RedirectPolicy with a maximum number of redirects.

A Error::TooManyRedirects will be returned if the max is reached.

fn none() -> RedirectPolicy

Create a RedirectPolicy that does not follow any redirect.

fn custom<T>(policy: T) -> RedirectPolicy where T: Fn(&Url, &[Url]) -> Result<bool> + Send + Sync + 'static

Create a custom RedirectPolicy using the passed function.

Note

The default RedirectPolicy handles redirect loops and a maximum loop chain, but the custom variant does not do that for you automatically. The custom policy should have some way of handling those.

There are variants on ::Error for both cases that can be used as return values.

Example

client.redirect(RedirectPolicy::custom(|next, previous| {
    if previous.len() > 5 {
        Err(reqwest::Error::TooManyRedirects)
    } else if next.host_str() == Some("example.domain") {
        // prevent redirects to 'example.domain'
        Ok(false)
    } else {
        Ok(true)
    }
}));
