当我尝试匹配 json 数组中的双精度值时，它失败了，预期值周围有尖括号。这是什么意思？

Question

使用 RestAssured 我尝试检查 JSON 的以下部分：

    {
        "id": "abc1",
        "commonName": "Plane",
        "location": [
            1.1,
            1.1
        ]
    }

使用以下 java 代码：

    double[] location = new double[]{1.1,1.1};
    given()
    .when()
        .get("tree/abc1/")
    .then()
        .assertThat()
        .statusCode(HttpStatus.OK.value())
        .body("location[0]", is((location[0])));

最后一个断言失败并出现以下错误

    java.lang.AssertionError: 1 expectation failed.
    JSON path location[0] doesn't match.
    Expected: is <1.1>
      Actual: 1.1

预期值周围的尖括号表示什么，我怎样才能使断言成功？

Answer 1

JSON个数字的默认类型是float，放心使用。我认为尖括号表示类型不匹配。

解决方法是在给定的block中设置放心配置，指定号码类型

double[] location = new double[]{1.1,1.1};
given()
    .config(RestAssured.config().jsonConfig(jsonConfig().numberReturnType(JsonPathConfig.NumberReturnType.DOUBLE)))
.when()
    .get("tree/abc1/")
.then()
    .assertThat()
    .statusCode(HttpStatus.OK.value())
    .body("location[0]", is(location[0]));

Answer 2

返回浮点数和双精度数作为 BigDecimal

instead of having two different type of configuration, Convert all floats and doubles into BigDecimal and then Compare then in the hamcrest Matcher

When I attempt to match a double value from a json array it fails with the expected value having angle brackets around it. What does this mean?
