在Rest Assured中,getString()会将小数点后的值四舍五入到4位。

In Rest Assured, getString() round off the decimal values after 4 digit

问题

我有一个场景,我们需要从 JSON 响应体中读取纬度和经度。
纬度和经度的值如下所示:

"data": [{
  "city": "Mumbai",
  "country": "India",  
  "latitude": 19.0886993408,
  "longitude": 72.8678970337
  
}]

当我们尝试通过使用 JSONPATH 中的 getString() 来读取纬度和经度来验证 JSON 响应时,它会在小数位数后四舍五入为 4 位。

以下是 Java 代码:

String key = item.getKey();
String value = item.getValue();
JsonPath jsonPathEvaluator = response.jsonPath();
String strjson = jsonPathEvaluator.getString(key).toString().replaceAll("\\[\\](){}]", "");

输出显示:

纬度:-19.0887,而不是 19.0886993408

英文:

I have scenario, we need to read the latitude and Longitude from json response body.
The latitude and longitude has value like below

"data": [{
  "city": "Mumbai",
  "country": "India",  
  "latitude": 19.0886993408,
  "longitude": 72.8678970337
  
}

when We try to validate the JSON response by reading the latitude and longitude using JSONPATH
using getString() then it round off the value after 4 digit in decimal places.

Below is the code in java

String key = item.getKey();
String value = item.getValue();
JsonPath jsonPathEvaluator = response.jsonPath();
String strjson = jsonPathEvaluator.getString(key).toString().replaceAll("\\[\\](){}]", "");

Output display:

Latitude:-19.0887 instead of 19.0886993408

你可以尝试使用如下所述的 JsonPath.config:

使用它,您可以为 JsonPath 提供自定义配置。
在这里,我只是试图将我的数值数据转换为具有长十进制范围的双精度数。

String key = item.getKey();
String value = item.getValue();
JsonPath jsonPathEvaluator = response.jsonPath();
JsonPath.config = new JsonPathConfig(JsonPathConfig.NumberReturnType.DOUBLE);
String strjson = jsonPathEvaluator.getString(key).toString().replaceAll("\\[\\](){}]", "");


/* String json = "{
   "data": {
      "city": "Mumbai",
      "country": "India",
      "latitude": 19.0886993408,
      "longitude": 72.8678970337
   }
}";
JsonPath jsonPath = JsonPath.from(json);
JsonPath.config = new JsonPathConfig(JsonPathConfig.NumberReturnType.DOUBLE);
double strjson = jsonPath.get("data.latitude");
    
System.out.println(String.valueOf(strjson)); */

对我来说,它会打印出以下输出。

19.0886993408

英文:

You can try with JsonPath.config as mentioned here

Using it you can provide your custom configuration for JsonPath.
Here i am just trying to convert my numeric data with long decimal range double.

String key = item.getKey();
String value = item.getValue();
JsonPath jsonPathEvaluator = response.jsonPath();
JsonPath.config = new JsonPathConfig(JsonPathConfig.NumberReturnType.DOUBLE);
String strjson = jsonPathEvaluator.getString(key).toString().replaceAll("\\[\\](){}]", "");


/* String json = "{\n" +
"  \"data\": {\n" +
"    \"city\": \"Mumbai\",\n" +
"    \"country\": \"India\",\n" +
"    \"latitude\": 19.0886993408,\n" +
"    \"longitude\": 72.8678970337\n" +
"  }\n" +
"}";
JsonPath jsonPath = JsonPath.from(json);
JsonPath.config = new JsonPathConfig(JsonPathConfig.NumberReturnType.DOUBLE);
double strjson = jsonPath.get("data.latitude");
    
System.out.println(String.valueOf(strjson)); */

For me it's printing below output.

19.0886993408
