以下是通过代理访问HTTPS网站的尝试:
我遇到了这个错误:
extern crate hyper;
extern crate hyper_native_tls;
use hyper::net::HttpsConnector;
use hyper::client::{Client, ProxyConfig};
use hyper_native_tls::NativeTlsClient;
fn main() {
let ssl = NativeTlsClient::new().unwrap();
let connector = HttpsConnector::new(ssl);
let client = Client::with_proxy_config(
ProxyConfig::new(
"http", "localhost", 3128, connector, ssl
)
);
let response = client.get("https://httpbin.org").send().unwrap();
println!("{}", response.headers);
}
我遇到了这个错误:

以下是 Cargo 依赖关系:
[dependencies]
hyper = "0.10"
hyper-native-tls = "0.2"
使用以下依赖项可以使事情变得更好:
[dependencies]
hyper = "0.10"
hyper-openssl = "0.2"
以下是该代码:
extern crate hyper;
extern crate hyper_openssl;
use hyper::net::HttpsConnector;
use hyper::client::{Client, ProxyConfig};
use hyper_openssl::OpensslClient as TlsClient;
fn main() {
let ssl = TlsClient::new().unwrap();
let connector = HttpsConnector::new(ssl.clone());
let client = Client::with_proxy_config(
ProxyConfig::new(
"http", "localhost", 3128, connector, ssl
)
);
let response = client.get("https://httpbin.org").send().unwrap();
println!("{:#?}", response);
}
输出:

没有构建失败,但它不通过代理。
hyper_native_tls
上的任何结构似乎都没有实现Debug
,因此该代码上看到的行为是正确的。请确保您没有执行任何fmt()
操作,并使用您的发现更新问题。 - E net4ProxyConfig
和Client
,两者都不需要Debug
,所以似乎OP自己给自己惹麻烦了...而且错误信息也不太好。或者他没有使用最新版本的hyper(0.10.0),因此我参考的文档可能不太好。 - Matthieu M.
