如何提取使用 RestApi 归档的 Json 数据？

Question

i make a post to an api with rest assured. and than i try to make sure expected data from responsed data, but i got some errors like this -> "java.lang.IllegalArgumentException: The parameter "data" was used but not defined. Define parameters using the JsonPath.params(...) function"

my code:

String payload_data = "{" +
                "\"Time\":1638057600, " +
                "\"exampleType\":example, " +
                "\"Id\":[2]}";

    RestAssured.defaultParser = Parser.JSON;
    given().
            contentType(ContentType.JSON).
            body(payload_data).
            when().
            post(api_url).
            then().
            statusCode(200).
            body("data.examples.2.exampleData", equalTo("33"));
}

my json data

{
    "success": true,
    "data": {
        "examples": {
            "2": {
                "ex_data": 0,
                "exampleData": 33,
                "data_ex": 0,
            }
      }
}

First, I tested path "data.examples.2.exampleData" with your json, it works fine. No problem.

You made some mistakes here.

1. Your payload is invalid json.

{
  "Time": 1638057600,
  "exampleType": example, //it must be number or String with double quote
  "Id": [
    2
  ]
}

2. You are comparing 2 things with different data types.

"data.examples.2.exampleData" --> int 33

equalTo("33") --> String "33"

Fix: body("data.examples.2.exampleData", equalTo(33));
