proxy.ProxyInfo 编辑

Contains information about a proxy. This object, or an array of these objects, is returned from the listener to proxy.onRequest. It instructs the browser whether to proxy the request, and if so, which proxy to use.

Type

Values of this type are objects. They contain the following properties:

type

string. This describes whether to proxy at all, and if so, what kind of proxy to use. It may take one of the following values:

• "direct": don't proxy the request. If this value is given, all other properties of this object are ignored.
• "http": HTTP proxy (or SSL CONNECT for HTTPS)
• "https": HTTP proxying over TLS connection to proxy
• "socks": SOCKS v5 proxy
• "socks4": SOCKS v4 proxy

host

string. The hostname of the proxy server. Mandatory unless type is "direct".

port

string. The port number of the proxy server. Mandatory unless type is "direct".

username

string. Username for the proxy service. This is usable with "socks". For HTTP proxy authorizations, use webRequest.onAuthRequired.

password

string. Password for the proxy service. This is usable with "socks". For HTTP proxy authorizations, use webRequest.onAuthRequired.

proxyDNS

boolean. If true, the proxy server is used to resolve certain DNS queries (only usable with "socks4" and "socks"). Defaults to false.

failoverTimeout

number.  Failover timeout in seconds. If the connection fails to connect the proxy server after this number of seconds, the next proxy server in the array returned from the proxy.onRequest listener will be used.

proxyAuthorizationHeader

string. This string, if set to non-empty, is passed directly as a value to the Proxy-Authorization request header sent to HTTP proxies as part of plain HTTP requests and CONNECT requests. In other words, this can be used to directly authenticate to HTTP proxies requiring (non-challenging) authentication.

For instance, if you want to send "username" and "password" for "basic" authentication, you can set the proxyAuthorizationHeader property to Basic dXNlcm5hbWU6cGFzc3dvcmQ=

connectionIsolationKey Optional

string. An optional key used for additional isolation of this proxy connection.
