// Each exported struct field is encoded as a URL parameter unless

//
|

// - the field's tag is "-", or

// - the field is empty and its tag specifies the "omitempty" option

// for IsZero().
|

//
|

// The URL parameter name defaults to the struct field name but can be
|
||||
// specified in the struct field's tag value. The "url" key in the struct
|

// field's tag value is the key name, followed by an optional comma and

// options. For example:
|
||||
//
|
||||
// // Field is ignored by this package.
|

// Field int `url:"-"`
|

//
|
||||
// // Field appears as URL parameter "myName".

//
|

// // Field appears as URL parameter "myName" and the field is omitted if
|

// // its value is empty
|

// Field int `url:"myName,omitempty"`
|

//
|
||||
// // Field appears as URL parameter "Field" (the default), but the field
|
||||
// // is skipped if empty. Note the leading comma.
|
||||
// Field int `url:",omitempty"`
|
||||
//
|
||||
// For encoding individual field values, the following type-dependent rules
|
||||
// apply:
|
||||
//
|
||||
// Boolean values default to encoding as the strings "true" or "false".
|
||||
// Including the "int" option signals that the field should be encoded as the
|
||||
// strings "1" or "0".
|
||||
//
|
||||
// time.Time values default to encoding as RFC3339 timestamps. Including the
|
||||
// "unix" option signals that the field should be encoded as a Unix time (see
|
||||
// time.Unix())
|
||||
//
|
||||
// Slice and Array values default to encoding as multiple URL values of the
|
||||
// same name. Including the "comma" option signals that the field should be
|
||||
// encoded as a single comma-delimited value. Including the "space" option
|
||||
// similarly encodes the value as a single space-delimited string. Including
|
||||
// the "semicolon" option will encode the value as a semicolon-delimited string.
|
||||
// Including the "brackets" option signals that the multiple URL values should
|
||||
// have "[]" appended to the value name. "numbered" will append a number to
|
||||
// the end of each incidence of the value name, example:
|
||||
// name0=value0&name1=value1, etc.
|
||||
//
|
||||
// Anonymous struct fields are usually encoded as if their inner exported
|
||||
// fields were fields in the outer struct, subject to the standard Go
|
||||
// visibility rules. An anonymous struct field with a name given in its URL
|
||||
// tag is treated as having that name, rather than being anonymous.
|
||||
//
|
||||
// Non-nil pointer values are encoded as the value pointed to.
|
||||
//
|
||||
// Nested structs are encoded including parent fields in value names for
|
||||
// scoping. e.g:
|
||||
//
|
||||
// "user[name]=acme&user[addr][postcode]=1234&user[addr][city]=SFO"
|
||||
//
|
||||
// All other values are encoded using their default string representation.
