Types

type Accounts

type Accounts map[string]string

Accounts defines a key/value for user/pass list of authorized logins.

type Context

type Context struct {
	Request *http.Request
	Writer  ResponseWriter

	Params Params

	// Keys is a key/value pair exclusively for the context of each request.
	Keys map[string]interface{}

	// Errors is a list of errors attached to all the handlers/middlewares who used this context.
	Errors util.ErrorMsgs

	// Accepted defines a list of manually accepted formats for content negotiation.
	Accepted []string
	// contains filtered or unexported fields
}

Context is the most important part of ego. It allows us to pass variables between middleware, manage the flow, validate the JSON of a request and render a JSON response for example. type Context struct {

func (*Context) Abort

func (c *Context) Abort()

Abort prevents pending handlers from being called. Note that this will not stop the current handler. Let's say you have an authorization middleware that validates that the current request is authorized. If the authorization fails (ex: the password does not match), call Abort to ensure the remaining handlers for this request are not called.

func (*Context) AbortWithError

func (c *Context) AbortWithError(code int, err error) *util.Error

AbortWithError calls `AbortWithStatus()` and `Error()` internally. This method stops the chain, writes the status code and pushes the specified error to `c.Errors`. See Context.Error() for more details.

func (*Context) AbortWithStatus

func (c *Context) AbortWithStatus(code int)

AbortWithStatus calls `Abort()` and writes the headers with the specified status code. For example, a failed attempt to authenticate a request could use: context.AbortWithStatus(401).

func (*Context) AbortWithStatusJSON

func (c *Context) AbortWithStatusJSON(code int, jsonObj interface{})

AbortWithStatusJSON calls `Abort()` and then `JSON` internally. This method stops the chain, writes the status code and return a JSON body It also sets the Content-Type as "application/json".

func (*Context) AsciiJSON

func (c *Context) AsciiJSON(code int, obj interface{})

AsciiJSON serializes the given struct as JSON into the response body with unicode to ASCII string. It also sets the Content-Type as "application/json".

func (*Context) Bind

func (c *Context) Bind(obj interface{}) error

Bind checks the Content-Type to select a binding engine automatically, Depending the "Content-Type" header different bindings are used:

"application/json" --> JSON binding
"application/xml"  --> XML binding

otherwise --> returns an error. It parses the request's body as JSON if Content-Type == "application/json" using JSON or XML as a JSON input. It decodes the json payload into the struct specified as a pointer. It writes a 400 error and sets Content-Type header "text/plain" in the response if input is not valid.

func (*Context) BindJSON

func (c *Context) BindJSON(obj interface{}) error

BindJSON is a shortcut for c.BindWith(obj, binding.JSON).

func (*Context) BindQuery

func (c *Context) BindQuery(obj interface{}) error

BindQuery is a shortcut for c.BindWith(obj, binding.Query).

func (*Context) BindWith

func (c *Context) BindWith(obj interface{}, b binding.Binding) error

BindWith binds the passed struct pointer using the specified binding engine. It will abort the request with HTTP 400 if any error ocurrs. See the binding package.

func (*Context) ClientIP

func (c *Context) ClientIP() string

ClientIP implements a best effort algorithm to return the real client IP, it parses X-Real-IP and X-Forwarded-For in order to work properly with reverse-proxies such us: nginx or haproxy. Use X-Forwarded-For before X-Real-Ip as nginx uses X-Real-Ip with the proxy's IP.

func (*Context) ContentType

func (c *Context) ContentType() string

ContentType returns the Content-Type header of the request.

func (*Context) Cookie

func (c *Context) Cookie(name string) (string, error)

Cookie returns the named cookie provided in the request or ErrNoCookie if not found. And return the named cookie is unescaped. If multiple cookies match the given name, only one cookie will be returned.

func (*Context) Copy

func (c *Context) Copy() *Context

Copy returns a copy of the current context that can be safely used outside the request's scope. This has to be used when the context has to be passed to a goroutine.

func (*Context) Data

func (c *Context) Data(code int, contentType string, data []byte)

Data writes some data into the body stream and updates the HTTP code.

func (*Context) DataFromReader

func (c *Context) DataFromReader(code int, contentLength int64,
	contentType string, reader io.Reader, extraHeaders map[string]string)

DataFromReader writes the specified reader into the body stream and updates the HTTP code.

func (*Context) Deadline

func (c *Context) Deadline() (deadline time.Time, ok bool)

Deadline returns the time when work done on behalf of this context should be canceled. Deadline returns ok==false when no deadline is set. Successive calls to Deadline return the same results.

func (*Context) DefaultPostForm

func (c *Context) DefaultPostForm(key, defaultValue string) string

DefaultPostForm returns the specified key from a POST urlencoded form or multipart form when it exists, otherwise it returns the specified defaultValue string. See: PostForm() and GetPostForm() for further information.

func (*Context) DefaultQuery

func (c *Context) DefaultQuery(key, defaultValue string) string

DefaultQuery returns the keyed url query value if it exists, otherwise it returns the specified defaultValue string. See: Query() and GetQuery() for further information.

GET /?name=Manu&lastname=
c.DefaultQuery("name", "unknown") == "Manu"
c.DefaultQuery("id", "none") == "none"
c.DefaultQuery("lastname", "none") == ""

func (*Context) Done

func (c *Context) Done() <-chan struct{}

Done returns a channel that's closed when work done on behalf of this context should be canceled. Done may return nil if this context can never be canceled. Successive calls to Done return the same value.

func (*Context) Err

func (c *Context) Err() error

Err returns a non-nil error value after Done is closed, successive calls to Err return the same error. If Done is not yet closed, Err returns nil. If Done is closed, Err returns a non-nil error explaining why: Canceled if the context was canceled or DeadlineExceeded if the context's deadline passed.

func (*Context) Error

func (c *Context) Error(err error) *util.Error

Error attaches an error to the current context. The error is pushed to a list of errors. It's a good idea to call Error for each error that occurred during the resolution of a request. A middleware can be used to collect all the errors and push them to a database together, print a log, or append it in the HTTP response. Error will panic if err is nil.

func (*Context) FFJSON

func (c *Context) FFJSON(code int, obj interface{})

	RouterGroup

	// Enables automatic redirection if the current route can't be matched but a
	// handler for the path with (without) the trailing slash exists.
	// For example if /foo/ is requested but a route only exists for /foo, the
	// client is redirected to /foo with http status code 301 for GET requests
	// and 307 for all other request methods.
	RedirectTrailingSlash bool

	// If enabled, the router tries to fix the current request path, if no
	// handle is registered for it.
	// First superfluous path elements like ../ or // are removed.
	// Afterwards the router does a case-insensitive lookup of the cleaned path.
	// If a handle can be found for this route, the router makes a redirection
	// to the corrected path with status code 301 for GET requests and 307 for
	// all other request methods.
	// For example /FOO and /..//Foo could be redirected to /foo.
	// RedirectTrailingSlash is independent of this option.
	RedirectFixedPath bool

	// If enabled, the router checks if another method is allowed for the
