## Migration Guide from v2 -> v3
|
||||
|
||||
Version 3 adds several new, frequently requested features. To do so, it introduces a few breaking changes. We've worked to keep these as minimal as possible. This guide explains the breaking changes and how you can quickly update your code.
|
||||
|
||||
### `Token.Claims` is now an interface type
|
||||
|
||||
The most requested feature from the 2.0 verison of this library was the ability to provide a custom type to the JSON parser for claims. This was implemented by introducing a new interface, `Claims`, to replace `map[string]interface{}`. We also included two concrete implementations of `Claims`: `MapClaims` and `StandardClaims`.
|
||||
|
||||
`MapClaims` is an alias for `map[string]interface{}` with built in validation behavior. It is the default claims type when using `Parse`. The usage is unchanged except you must type cast the claims property.
|
||||
|
||||
The old example for parsing a token looked like this..
|
||||
|
||||
```go
|
||||
if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
|
||||
fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
|
||||
}
|
||||
```
|
||||
|
||||
is now directly mapped to...
|
||||
|
||||
```go
|
||||
if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
|
||||
claims := token.Claims.(jwt.MapClaims)
|
||||
fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
|
||||
}
|
||||
```
|
||||
|
||||
`StandardClaims` is designed to be embedded in your custom type. You can supply a custom claims type with the new `ParseWithClaims` function. Here's an example of using a custom claims type.
|
||||
|
||||
```go
|
||||
type MyCustomClaims struct {
|
||||
User string
|
||||
*StandardClaims
|
||||
}
|
||||
|
||||
if token, err := jwt.ParseWithClaims(tokenString, &MyCustomClaims{}, keyLookupFunc); err == nil {
|
||||
claims := token.Claims.(*MyCustomClaims)
|
||||
fmt.Printf("Token for user %v expires %v", claims.User, claims.StandardClaims.ExpiresAt)
|
||||
}
|
||||
```
|
||||
|
||||
### `ParseFromRequest` has been moved
|
||||
|
||||
To keep this library focused on the tokens without becoming overburdened with complex request processing logic, `ParseFromRequest` and its new companion `ParseFromRequestWithClaims` have been moved to a subpackage, `request`. The method signatues have also been augmented to receive a new argument: `Extractor`.
|
||||
|
||||
`Extractors` do the work of picking the token string out of a request. The interface is simple and composable.
|
||||
|
||||
This simple parsing example:
|
||||
|
||||
```go
|
||||
if token, err := jwt.ParseFromRequest(tokenString, req, keyLookupFunc); err == nil {
|
||||
fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
|
||||
}
|
||||
```
|
||||
|
||||
is directly mapped to:
|
||||
|
||||
```go
|
||||
if token, err := request.ParseFromRequest(req, request.OAuth2Extractor, keyLookupFunc); err == nil {
|
||||
claims := token.Claims.(jwt.MapClaims)
|
||||
fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
|
||||
}
|
||||
```
|
||||
|
||||
There are several concrete `Extractor` types provided for your convenience:
|
||||
|
||||
* `HeaderExtractor` will search a list of headers until one contains content.
|
||||
* `ArgumentExtractor` will search a list of keys in request query and form arguments until one contains content.
|
||||
* `MultiExtractor` will try a list of `Extractors` in order until one returns content.
|
||||
* `AuthorizationHeaderExtractor` will look in the `Authorization` header for a `Bearer` token.
|
||||
* `OAuth2Extractor` searches the places an OAuth2 token would be specified (per the spec): `Authorization` header and `access_token` argument
|
||||
* `PostExtractionFilter` wraps an `Extractor`, allowing you to process the content before it's parsed. A simple example is stripping the `Bearer ` text from a header
|
||||
|
||||
|
||||
### RSA signing methods no longer accept `[]byte` keys
|
||||
|
||||
Due to a [critical vulnerability](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/), we've decided the convenience of accepting `[]byte` instead of `rsa.PublicKey` or `rsa.PrivateKey` isn't worth the risk of misuse.
|
||||
|
||||
To replace this behavior, we've added two helper methods: `ParseRSAPrivateKeyFromPEM(key []byte) (*rsa.PrivateKey, error)` and `ParseRSAPublicKeyFromPEM(key []byte) (*rsa.PublicKey, error)`. These are just simple helpers for unpacking PEM encoded PKCS1 and PKCS8 keys. If your keys are encoded any other way, all you need to do is convert them to the `crypto/rsa` package's types.
|
||||
|
||||
```go
|
||||
func keyLookupFunc(*Token) (interface{}, error) {
|
||||
// Don't forget to validate the alg is what you expect:
|
||||
if _, ok := token.Method.(*jwt.SigningMethodRSA); !ok {
|
||||
return nil, fmt.Errorf("Unexpected signing method: %v", token.Header["alg"])
|
||||
}
|
||||
|
||||
// Look up key
|
||||
key, err := lookupPublicKey(token.Header["kid"])
|
||||
if err != nil {
|
||||
return nil, err
|
||||
}
|
||||
|
||||
// Unpack key from PEM encoded PKCS8
|
||||
return jwt.ParseRSAPublicKeyFromPEM(key)
|
||||
}
|
||||
```

|
||||
Package imaging provides basic image processing functions (resize, rotate, crop, brightness/contrast adjustments, etc.).
|
||||
|
||||
All the image processing functions provided by the package accept any image type that implements `image.Image` interface
|
||||
as an input, and return a new image of `*image.NRGBA` type (32bit RGBA colors, non-premultiplied alpha).
|
||||
|
||||
## Installation
|
||||
|
||||
go get -u github.com/disintegration/imaging
|
||||
|
||||
## Documentation
|
||||
|
||||
http://godoc.org/github.com/disintegration/imaging
|
||||
|
||||
## Usage examples
|
||||
|
||||
A few usage examples can be found below. See the documentation for the full list of supported functions.
|
||||
|
||||
### Image resizing
|
||||
|
||||
```go
|
||||
// Resize srcImage to size = 128x128px using the Lanczos filter.
|
||||
dstImage128 := imaging.Resize(srcImage, 128, 128, imaging.Lanczos)
|
||||
|
||||
// Resize srcImage to width = 800px preserving the aspect ratio.
|
||||
dstImage800 := imaging.Resize(srcImage, 800, 0, imaging.Lanczos)
|
||||
|
||||
// Scale down srcImage to fit the 800x600px bounding box.
|
||||
dstImageFit := imaging.Fit(srcImage, 800, 600, imaging.Lanczos)
|
||||
|
||||
// Resize and crop the srcImage to fill the 100x100px area.
|
||||
dstImageFill := imaging.Fill(srcImage, 100, 100, imaging.Center, imaging.Lanczos)
|
||||
```
|
||||
|
||||
Imaging supports image resizing using various resampling filters. The most notable ones:
|
||||
- `Lanczos` - A high-quality resampling filter for photographic images yielding sharp results.
|
||||
- `CatmullRom` - A sharp cubic filter that is faster than Lanczos filter while providing similar results.
|
||||
- `MitchellNetravali` - A cubic filter that produces smoother results with less ringing artifacts than CatmullRom.
|
||||
- `Linear` - Bilinear resampling filter, produces smooth output. Faster than cubic filters.
|
||||
- `Box` - Simple and fast averaging filter appropriate for downscaling. When upscaling it's similar to NearestNeighbor.
|
||||
- `NearestNeighbor` - Fastest resampling filter, no antialiasing.
|
||||
|
||||
The full list of supported filters: NearestNeighbor, Box, Linear, Hermite, MitchellNetravali, CatmullRom, BSpline, Gaussian, Lanczos, Hann, Hamming, Blackman, Bartlett, Welch, Cosine. Custom filters can be created using ResampleFilter struct.
|
||||
|
||||
**Resampling filters comparison**
|
||||
|
||||
Original image:
|
||||
|
||||
|
||||
|
||||
The same image resized from 600x400px to 150x100px using different resampling filters.
|
||||
From faster (lower quality) to slower (higher quality):
|
||||
|
||||
Filter | Resize result
|
||||
--------------------------|---------------------------------------------
|
||||
`imaging.NearestNeighbor` | 
|
||||
`imaging.Linear` | 
|
||||
`imaging.CatmullRom` | 
|
||||
`imaging.Lanczos` | 
|
||||
|
||||
|
||||
### Gaussian Blur
|
||||
|
||||
```go
|
||||
dstImage := imaging.Blur(srcImage, 0.5)
|
||||
```
|
||||
|
||||
Sigma parameter allows to control the strength of the blurring effect.
|
||||
|
||||
Original image | Sigma = 0.5 | Sigma = 1.5
|
||||
-----------------------------------|----------------------------------------|---------------------------------------
|
||||
 |  | 
|
||||
|
||||
### Sharpening
|
||||
|
||||
```go
|
||||
dstImage := imaging.Sharpen(srcImage, 0.5)
|
||||
```
|
||||
|
||||
`Sharpen` uses gaussian function internally. Sigma parameter allows to control the strength of the sharpening effect.
|
||||
|
||||
Original image | Sigma = 0.5 | Sigma = 1.5
|
||||
-----------------------------------|-------------------------------------------|------------------------------------------
|
||||
 |  | 
|
||||
|
||||
### Gamma correction
|
||||
|
||||
```go
|
||||
dstImage := imaging.AdjustGamma(srcImage, 0.75)
|
||||
```
|
||||
|
||||
Original image | Gamma = 0.75 | Gamma = 1.25
|
||||
-----------------------------------|------------------------------------------|-----------------------------------------
|
||||
 |  | 
|
||||
|
||||
### Contrast adjustment
|
||||
|
||||
```go
|
||||
dstImage := imaging.AdjustContrast(srcImage, 20)
|
||||
```
|
||||
|
||||
Original image | Contrast = 15 | Contrast = -15
|
||||
-----------------------------------|--------------------------------------------|-------------------------------------------

### Brightness adjustment
|
||||
|
||||
```go
|
||||
dstImage := imaging.AdjustBrightness(srcImage, 20)
|
||||
```
|
||||
|
||||
Original image | Brightness = 10 | Brightness = -10
|
||||
-----------------------------------|----------------------------------------------|---------------------------------------------
|
||||
 |  | 
|
||||
|
||||
### Saturation adjustment
|
||||
|
||||
```go
|
||||
dstImage := imaging.AdjustSaturation(srcImage, 20)
|
||||
```
|
||||
|
||||
Original image | Saturation = 30 | Saturation = -30

## FAQ
|
||||
|
||||
### Incorrect image orientation after processing (e.g. an image appears rotated after resizing)
|
||||
|
||||
Most probably, the given image contains the EXIF orientation tag.
|
||||
The stadard `image/*` packages do not support loading and saving
|
||||
this kind of information. To fix the issue, try opening images with
|
||||
the `AutoOrientation` decode option. If this option is set to `true`,
|
||||
the image orientation is changed after decoding, according to the
|
||||
orientation tag (if present). Here's the example:
|
||||
|
||||
```go
|
||||
img, err := imaging.Open("test.jpg", imaging.AutoOrientation(true))
|
||||
```
|
||||
|
||||
### What's the difference between `imaging` and `gift` packages?
|
||||
|
||||
[imaging](https://github.com/disintegration/imaging)
|
||||
is designed to be a lightweight and simple image manipulation package.
|
||||
It provides basic image processing functions and a few helper functions
|
||||
such as `Open` and `Save`. It consistently returns *image.NRGBA image
|
||||
type (8 bits per channel, RGBA).
|
||||
|
||||
[gift](https://github.com/disintegration/gift)
|
||||
supports more advanced image processing, for example, sRGB/Linear color
|
||||
space conversions. It also supports different output image types
|
||||
(e.g. 16 bits per channel) and provides easy-to-use API for chaining
|
||||
multiple processing steps together.
|
||||
|
||||

## Migration Guide (v3.2.1)
|
||||
|
||||
Starting from [v3.2.1](https://github.com/golang-jwt/jwt/releases/tag/v3.2.1]), the import path has changed from `github.com/dgrijalva/jwt-go` to `github.com/golang-jwt/jwt`. Future releases will be using the `github.com/golang-jwt/jwt` import path and continue the existing versioning scheme of `v3.x.x+incompatible`. Backwards-compatible patches and fixes will be done on the `v3` release branch, where as new build-breaking features will be developed in a `v4` release, possibly including a SIV-style import path.
|
||||
|
||||
### go.mod replacement
|
||||
|
||||
In a first step, the easiest way is to use `go mod edit` to issue a replacement.
|
||||
|
||||
```
|
||||
go mod edit -replace github.com/dgrijalva/jwt-go=github.com/golang-jwt/jwt@v3.2.1+incompatible
|
||||
go mod tidy
|
||||
```
|
||||
|
||||
This will still keep the old import path in your code but replace it with the new package and also introduce a new indirect dependency to `github.com/golang-jwt/jwt`. Try to compile your project; it should still work.
|
||||
|
||||
### Cleanup
|
||||
|
||||
If your code still consistently builds, you can replace all occurences of `github.com/dgrijalva/jwt-go` with `github.com/golang-jwt/jwt`, either manually or by using tools such as `sed`. Finally, the `replace` directive in the `go.mod` file can be removed.
|
||||
|
||||
## Older releases (before v3.2.0)

||||

||||
