Types

type FCGIClient

type FCGIClient struct {
	// contains filtered or unexported fields
}

FCGIClient implements a FastCGI client, which is a standard for interfacing external applications with Web servers.

func Dial

func Dial(network, address string) (fcgi *FCGIClient, err error)

Dial connects to the fcgi responder at the specified network address, using default net.Dialer. See func net.Dial for a description of the network and address parameters.

func DialContext

func DialContext(ctx context.Context, network, address string) (fcgi *FCGIClient, err error)

DialContext is like Dial but passes ctx to dialer.Dial.

func DialWithDialerContext

func DialWithDialerContext(ctx context.Context, network, address string, dialer net.Dialer) (fcgi *FCGIClient, err error)

DialWithDialerContext connects to the fcgi responder at the specified network address, using custom net.Dialer and a context. See func net.Dial for a description of the network and address parameters.

func (*FCGIClient) Close

func (c *FCGIClient) Close()

Close closes fcgi connection

func (*FCGIClient) Do

func (c *FCGIClient) Do(p map[string]string, req io.Reader) (r io.Reader, err error)

Do made the request and returns a io.Reader that translates the data read from fcgi responder out of fcgi packet before returning it.

func (*FCGIClient) Get

func (c *FCGIClient) Get(p map[string]string, body io.Reader, l int64) (resp *http.Response, err error)

Get issues a GET request to the fcgi responder.

func (*FCGIClient) Head

func (c *FCGIClient) Head(p map[string]string) (resp *http.Response, err error)

Head issues a HEAD request to the fcgi responder.

func (*FCGIClient) Options

func (c *FCGIClient) Options(p map[string]string) (resp *http.Response, err error)

Options issues an OPTIONS request to the fcgi responder.

func (*FCGIClient) Post

func (c *FCGIClient) Post(p map[string]string, method string, bodyType string, body io.Reader, l int64) (resp *http.Response, err error)

Post issues a POST request to the fcgi responder. with request body in the format that bodyType specified

func (*FCGIClient) PostFile

func (c *FCGIClient) PostFile(p map[string]string, data url.Values, file map[string]string) (resp *http.Response, err error)

PostFile issues a POST to the fcgi responder in multipart(RFC 2046) standard, with form as a string key to a list values (url.Values), and/or with file as a string key to a list file path.

func (*FCGIClient) PostForm

func (c *FCGIClient) PostForm(p map[string]string, data url.Values) (resp *http.Response, err error)

PostForm issues a POST to the fcgi responder, with form as a string key to a list values (url.Values)

func (*FCGIClient) Request

func (c *FCGIClient) Request(p map[string]string, req io.Reader) (resp *http.Response, err error)

Request returns a HTTP Response with Header and Body from fcgi responder

func (*FCGIClient) SetReadTimeout

func (c *FCGIClient) SetReadTimeout(t time.Duration) error

SetReadTimeout sets the read timeout for future calls that read from the fcgi responder. A zero value for t means no timeout will be set.

func (*FCGIClient) SetWriteTimeout

func (c *FCGIClient) SetWriteTimeout(t time.Duration) error

SetWriteTimeout sets the write timeout for future calls that send data to the fcgi responder. A zero value for t means no timeout will be set.

type Transport

type Transport struct {
	// Use this directory as the fastcgi root directory. Defaults to the root
	// directory of the parent virtual host.
	Root string `json:"root,omitempty"`

	// The path in the URL will be split into two, with the first piece ending
	// with the value of SplitPath. The first piece will be assumed as the
	// actual resource (CGI script) name, and the second piece will be set to
	// PATH_INFO for the CGI script to use.
	//
	// Future enhancements should be careful to avoid CVE-2019-11043,
	// which can be mitigated with use of a try_files-like behavior
	// that 404s if the fastcgi path info is not found.
	SplitPath []string `json:"split_path,omitempty"`

	// Path declared as root directory will be resolved to its absolute value
	// after the evaluation of any symbolic links.
	// Due to the nature of PHP opcache, root directory path is cached: when
	// using a symlinked directory as root this could generate errors when
	// symlink is changed without php-fpm being restarted; enabling this
	// directive will set $_SERVER['DOCUMENT_ROOT'] to the real directory path.
	ResolveRootSymlink bool `json:"resolve_root_symlink,omitempty"`

	// Extra environment variables.
	EnvVars map[string]string `json:"env,omitempty"`

	// The duration used to set a deadline when connecting to an upstream.
	DialTimeout caddy.Duration `json:"dial_timeout,omitempty"`

	// The duration used to set a deadline when reading from the FastCGI server.
	ReadTimeout caddy.Duration `json:"read_timeout,omitempty"`

	// The duration used to set a deadline when sending to the FastCGI server.
	WriteTimeout caddy.Duration `json:"write_timeout,omitempty"`
	// contains filtered or unexported fields
}

Transport facilitates FastCGI communication.

func (Transport) CaddyModule

func (Transport) CaddyModule() caddy.ModuleInfo

CaddyModule returns the Caddy module information.

func (*Transport) Provision

func (t *Transport) Provision(ctx caddy.Context) error

Provision sets up t.

func (Transport) RoundTrip

func (t Transport) RoundTrip(r *http.Request) (*http.Response, error)

RoundTrip implements http.RoundTripper.

func (*Transport) UnmarshalCaddyfile

func (t *Transport) UnmarshalCaddyfile(d *caddyfile.Dispenser) error

UnmarshalCaddyfile deserializes Caddyfile tokens into h.
