Java 如何修改现有Json文件中的值?
我有一个名为“addplace.json”的json文件,其内容粘贴在下面。现在我需要阅读上面提到的json文件,并更改纬度、经度、姓名、电话和地址的值。那么我将如何做到这一点,请用示例java代码告诉我Java 如何修改现有Json文件中的值?,java,json,rest,rest-assured,Java,Json,Rest,Rest Assured,我有一个名为“addplace.json”的json文件,其内容粘贴在下面。现在我需要阅读上面提到的json文件,并更改纬度、经度、姓名、电话和地址的值。那么我将如何做到这一点,请用示例java代码告诉我 { "location": { "lat": -33.8669710, "lng": 151.1958750 }, "accuracy": 50, "name": "Google Shoes!", "phone_number": "(02) 9374 400

提前感谢。抱歉,忘记了延迟响应。下面是我用来在运行时读取json文件、修改它并作为post操作的一部分触发修改后的json的代码
public class Post_Ex3 extends BaseStepClass{
public Scenario scenario;
@Before
public void beforeTest(Scenario scenario)
{
this.scenario =scenario;
}
@When("user changes the attributes values like name {string} , Salary {string} and age {string} in json payload file {string}")
public void user_changes_the_attributes_values_like_name_Salary_and_age_in_json_payload_file(String name, String salary, String age, String payloadfileName) {
String filepath = System.getProperty("user.dir")+"\\src\\test\\resources\\JsonFiles\\"+payloadfileName;
System.out.println("path : " +filepath);
try {
String jsonContents = new String((Files.readAllBytes(Paths.get(filepath))));
JSONObject jsonObject= new JSONObject(jsonContents);
System.out.println(" Post Payload Before changes: ");
System.out.println("============================");
System.out.println(jsonObject.toString(4));
//changing the value of name from tammy to balaji
jsonObject.put("name", name);
jsonObject.put("salary", salary);
jsonObject.put("age", age);
System.out.println(" Post Payload after changes: ");
System.out.println("============================");
System.out.println(jsonObject.toString(4));
String payload = jsonObject.toString(4);
scenario.write("Payload Passed along with post request");
scenario.write(payload);
// Add a header stating the Request body is a JSON
httpRequest.header("Content-Type", "application/json");
// Add the Json to the body of the request
httpRequest.body(jsonObject.toString(4));
} catch (IOException e) {
System.out.println("No file found in the path ");
e.printStackTrace();
}
}
@When("user initiates post request with {string} endpoint")
public void user_initiates_post_request_with_endpoint(String string) {
response = httpRequest.post("/create");
}
@Then("user should get an status code as {string} in post response")
public void user_should_get_an_status_code_as_in_post_response(String expectedStatusCode) {
int statusCode = response.getStatusCode();
Assert.assertEquals(statusCode, Integer.parseInt(expectedStatusCode),"Failed due to Server issue -"+statusCode);
Assert.assertNotNull(response.asString());
System.out.println("Response :" + response.prettyPrint());
System.out.println("Status Code :" + response.getStatusCode());
System.out.println("Does Reponse contains 'tammy'? :" + response.asString().contains("tammy"));
String name = response.jsonPath().get("data.name").toString();
System.out.println(" name : " +name);
System.out.println(" Salary value in response : " +response.jsonPath().get("data.salary").toString());
}
}你应该先尝试一下,有很多教程介绍如何按照你的要求去做。如果你陷入困境,那么就回来分享你失败的代码。到目前为止你都尝试了什么?你能给我们举一些例子吗?在目前的形式下,这个问题不适合这样做;定义您的位置和地点类;从json反序列化;编辑您的数据;然后重新序列化为json格式?您能执行以下哪一个步骤?@NiVer我已尝试并寻求解决方案。我没有把代码贴在这里,这是我的错。下面是我尝试过的代码段。File jsonFile=new File(System.getProperty(“user.dir”)+“//resources//”+addPlace\u Payload.json);if(jsonFile.exists()){ObjectMapper mapper=new ObjectMapper();ObjectReader reader=mapper.reader();String jsonString=FileUtils.readFileToString(jsonFile);JsonNode节点=reader.readTree(jsonString);System.out.println(node.toString());ObjectNode ObjectNode ObjectNode=(ObjectNode)node;ObjectNode.put(“location.lat”,“-55.8669710”);objectNode.put(“name”,“Mysuru”);System.out.println(node.toString());}
