我可以使用以下代码设置http代理：
public class CustomFlurlHttpClient : DefaultHttpClientFactory {
public override HttpClient CreateClient(Url url, HttpMessageHandler m) {
return base.CreateClient(url, CreateProxyHttpClientHandler("http://192.168.0.103:9090"));
}
private HttpClientHandler CreateProxyHttpClientHandler(string proxyUrl, string user = "", string passw = "") {
NetworkCredential proxyCreds = null;
var proxyUri = new Uri(proxyUrl);
proxyCreds = new NetworkCredential (user, passw);
var proxy = new WebProxy (proxyUri, false) {
UseDefaultCredentials = false,
Credentials = proxyCreds
};
var clientHandler = new HttpClientHandler {
UseProxy = true,
Proxy = proxy,
PreAuthenticate = true,
UseDefaultCredentials = false …在 ssh 连接上创建 DialTimeout 的最佳方法是什么？例如，此代码始终返回“Ping 截止日期超出”：
func (t *Tunnel) ping(sshConn *ssh.Client, addr string) (net.Conn, error) {
var (
conn net.Conn
err error
done chan int
)
go func() {
time.Sleep(getSeconds(10))
err = errors.New("Ping deadline exceed")
log.Printf("%v\nStatus: bad %s -> %s", err, t.serverAddr, addr)
t.writeStatus(bad)
done <- 1
close(done)
}()
go func() {
conn, err = sshConn.Dial("tcp", addr)
if err != nil {
t.writeStatus(bad)
log.Printf("%v\nStatus: bad %s -> %s", err, t.serverAddr, addr)
}
done <- 1
close(done)
}()
<-done
return conn, …我有一个客户处理一个Future做一些事情的。是否可以impl Future<Item = (), Error = io::Error>用作返回类型并进行更好的错误处理？
pub fn handle_client(client: Client) -> impl Future<Item = (), Error = io::Error> {
let magic = client.header.magic;
let stream_client = TcpStream::connect(&client.addr).and_then(|stream| {
let addr: Vec<u8> = serialize_addr(stream.local_addr()?, magic)?;
write_all(stream, addr).then(|result| {
// some code
Ok(())
})
});
stream_client
}
我无法io::Error通过所有嵌套的闭包/期货保持该类型。编译器抛出错误
pub fn handle_client(client: Client) -> impl Future<Item = (), Error = io::Error> {
let magic = client.header.magic;
let stream_client = TcpStream::connect(&client.addr).and_then(|stream| {
let addr: Vec<u8> = serialize_addr(stream.local_addr()?, …
