public class JsonPath
extends Object

JsonPath is an alternative to using XPath for easily getting values from a Object document. It follows the Groovy GPath syntax when getting an object from the document. You can regard it as an alternative to XPath for JSON. E.g. given the following Object document:

 { "store": {
   "book": [
    { "category": "reference",
      "author": "Nigel Rees",
      "title": "Sayings of the Century",
      "price": 8.95
    },
    { "category": "fiction",
      "author": "Evelyn Waugh",
      "title": "Sword of Honour",
      "price": 12.99
    },
    { "category": "fiction",
      "author": "Herman Melville",
      "title": "Moby Dick",
      "isbn": "0-553-21311-3",
      "price": 8.99
    },
    { "category": "fiction",
      "author": "J. R. R. Tolkien",
      "title": "The Lord of the Rings",
      "isbn": "0-395-19395-8",
      "price": 22.99
    }
  ],
    "bicycle": {
      "color": "red",
      "price": 19.95
    }
  }
 }

To get a list of all book categories:

 List<String> categories = with(Object).get("store.book.category");

Get the first book category:

 String category = with(Object).get("store.book[0].category");

Get the last book category:

 String category = with(Object).get("store.book[-1].category");

Get all books with price between 5 and 15:

 List<Map> books = with(Object).get("store.book.findAll { book -> book.price >= 5 && book.price <= 15 }");

The JsonPath implementation of rest-assured uses a Groovy shell to evaluate expressions so be careful when injecting user input into the expression. For example avoid doing this:

 String name = System.console().readLine();
 List<Map> books = with(Object).get("store.book.findAll { book -> book.author == " + name + " }");

Instead use the param(java.lang.String, java.lang.Object) method like this:

 String name = System.console().readLine();
 List<Map> books = with(Object).param("name", name).get("store.book.findAll { book -> book.author == name }");

  - param
```
public JsonPath param(String key,
                      Object value)
```
    Add a parameter for the expression. Example:
```
 String name = System.console().readLine();
 List<Map> books = with(Object).param("name", name).get("store.book.findAll { book -> book.author == name }");
 
```
    Parameters:
    
    key - The name of the parameter. Just use this name in your expression as a variable
    
    value - The value of the parameter
    
    Returns:
    
    New JsonPath instance with the parameter set
  - peek
```
public JsonPath peek()
```
    Peeks into the JSON that JsonPath will parse by printing it to the console. You can continue working with JsonPath afterwards. This is mainly for debug purposes. If you want to return a prettified version of the content see prettify(). If you want to return a prettified version of the content and also print it to the console use prettyPrint().
    
    Note that the content is not guaranteed to be looking exactly like the it does at the source. This is because once you peek the content has been downloaded and transformed into another data structure (used by JsonPath) and the JSON is rendered from this data structure.
    
    Returns:
    
    The same JsonPath instance
  - prettyPeek
```
public JsonPath prettyPeek()
```
    Peeks into the JSON that JsonPath will parse by printing it to the console in a prettified manner. You can continue working with JsonPath afterwards. This is mainly for debug purposes. If you want to return a prettified version of the content see prettify(). If you want to return a prettified version of the content and also print it to the console use prettyPrint().
    
    Note that the content is not guaranteed to be looking exactly like the it does at the source. This is because once you peek the content has been downloaded and transformed into another data structure (used by JsonPath) and the JSON is rendered from this data structure.
    
    Returns:
    
    The same JsonPath instance
  - prettify
```
public String prettify()
```
    Get the JSON as a prettified string.
    Note that the content is not guaranteed to be looking exactly like the it does at the source. This is because once you peek the content has been downloaded and transformed into another data structure (used by JsonPath) and the JSON is rendered from this data structure.
    
    Returns:
    
    The JSON as a prettified String.
  - prettyPrint
```
public String prettyPrint()
```
    Get and print the JSON as a prettified string.
    Note that the content is not guaranteed to be looking exactly like the it does at the source. This is because once you peek the content has been downloaded and transformed into another data structure (used by JsonPath) and the JSON is rendered from this data structure.

    The JSON as a prettified String.
