|
|
An implementation of JSON Pointer for golang, which supports go `struct`.
|
|
|
|
## Status
|
|
|
|
API is stable.
|
|
|
|
## Import this library in your project
|
|
|
|
```cmd
|
|
go get github.com/go-openapi/jsonpointer
|
|
```
|
|
|
|
## Basic usage
|
|
|
|
See also some [examples](./examples_test.go)
|
|
|
|
### Retrieving a value
|
|
|
|
```go
|
|
import (
|
|
"github.com/go-openapi/jsonpointer"
|
|
)
|
|
|
|
|
|
var doc any
|
|
|
|
...
|
|
|
|
pointer, err := jsonpointer.New("/foo/1")
|
|
if err != nil {
|
|
... // error: e.g. invalid JSON pointer specification
|
|
}
|
|
|
|
value, kind, err := pointer.Get(doc)
|
|
if err != nil {
|
|
... // error: e.g. key not found, index out of bounds, etc.
|
|
}
|
|
|
|
...
|
|
```
|
|
|
|
### Setting a value
|
|
|
|
```go
|
|
...
|
|
var doc any
|
|
...
|
|
pointer, err := jsonpointer.New("/foo/1")
|
|
if err != nil {
|
|
... // error: e.g. invalid JSON pointer specification
|
|
}
|
|
|
|
doc, err = p.Set(doc, "value")
|
|
if err != nil {
|
|
... // error: e.g. key not found, index out of bounds, etc.
|
|
}
|
|
```
|
|
|
|
## Change log
|
|
|
|
See <https://github.com/go-openapi/jsonpointer/releases>
|
|
|
|
## References
|
|
|
|
<https://tools.ietf.org/html/draft-ietf-appsawg-json-pointer-07>
|
|
|
|
also known as [RFC6901](https://www.rfc-editor.org/rfc/rfc6901)
|
|
|
|
## Licensing
|
|
|
|
This library ships under the [SPDX-License-Identifier: Apache-2.0](./LICENSE).
|
|
|
|
See the license [NOTICE](./NOTICE), which recalls the licensing terms of all the pieces of software
|
|
on top of which it has been built.
|
|
|
|
## Limitations
|
|
|
|
The 4.Evaluation part of the previous reference, starting with 'If the currently referenced value is a JSON array,
|
|
the reference token MUST contain either...' is not implemented.
|
|
|
|
That is because our implementation of the JSON pointer only supports explicit references to array elements:
|
|
the provision in the spec to resolve non-existent members as "the last element in the array",
|
|
using the special trailing character "-" is not implemented.
|
|
