如何设置 post 来自 json 文件的请求负载

Question

在以下情况下需要帮助：

我有以下 pojo class，当我使用 restassured 进行 post 调用时，我不想在我的 java class.To 中设置每个字段来实现这些想要维护一个 createissue.json 个文件。 进行 post 调用时，我想从 createissue.json 文件中读取每个字段。

下面是我的pojoclassCreateIssuepayload.java

public class CreateIssuepayload {

@JsonProperty("summary")
private String summary;

@JsonProperty("description")
private String description;

@JsonProperty("issuetype")
private IssueType issuetype;

@JsonProperty("project")
private Project project;

public CreateIssuepayload(Project project, IssueType issuetype,String description,  String summary) {

    this.summary = summary;
    this.description = description;
    this.issuetype = issuetype;
    this.project = project;
}

public CreateIssuepayload(Project project,IssueType issuetype,String description) {

    this.description = description;
    this.issuetype = issuetype;
    this.project = project;
    
}

public String getSummary() {
    return summary;
}

public void setSummary(String summary) {
    this.summary = summary;
}

public String getDescription() {
    return description;
}

public void setDescription(String description) {
    this.description = description;
}

public IssueType getIssuetype() {
    return issuetype;
}

public void setIssuetype(IssueType issuetype) {
    this.issuetype = issuetype;
}

public Project getProject() {
    return project;
}

public void setProject(Project project) {
    this.project = project;
}

}

我的createissue.json文件

{
   "fields":{
      "summary":"Please look into issue",
      "description":"Unable to create my JIRA ticket 3",
      "issuetype":{
         "name":"Bug"
      },
      "project":{
         "key":"BP"
      }
   }
}

我的测试用例提出 post 请求

 @Test(enabled = false)
        public static void test1() throws JsonProcessingException {
            IssueType issuetype = new IssueType("**Bug**");
            Project project = new Project("**BP**");
            CreateIssuepayload mypojo = new CreateIssuepayload(project, issuetype, "**Unable to create my JIRA ticket 3**",
                    "**Please look into issue.....**");
            Fields f = new Fields(mypojo);
RestAssured.baseURI = "http://localhost:8080";
        Response res = given().header("Content-Type", "application/json")
                .header("cookie", "JSESSIONID=" + Basic.sessionGen() + "").body(f).expect()
                .body(containsString("greeting")).when().post("/rest/api/2/issue").then().extract().response();
        }

这里我不想从 java 中的测试用例中设置我的测试数据，如 Bug、BP 等 class.I 想从 json 文件

中动态读取它

注意：我也不想post整个json文件作为我的正文。

感谢任何帮助。谢谢。

您可以使用json-Java中的简单库来读取json文件。 Maven repository

然后检索字符串形式的值并创建 CreateIssuepayload 对象和 Fields 对象。

@Test(enabled = false)
public static void test1() throws JsonProcessingException {

    // Read the json file
    org.json.simple.JSONObject jsonObject = new org.json.simple.JSONObject();
    JSONParser parser = new JSONParser();
    try {
        Object obj = parser.parse(new FileReader("createissue.json"));

        jsonObject = (org.json.simple.JSONObject) obj;

    } catch (IOException e) {
        e.printStackTrace();
    } catch (ParseException e) {
        e.printStackTrace();
    }

    JSONObject fieldsObject = (JSONObject)  jsonObject.get("fields");
    JSONObject issueTypeObject = (JSONObject) fieldsObject.get("issuetype");
    JSONObject projectObject = (JSONObject) fieldsObject.get("project");

    IssueType issueType = new IssueType(issueTypeObject.get("name").toString());
    Project project = new Project(projectObject.get("key").toString());
    String summary = fieldsObject.get("summary").toString();
    String description = fieldsObject.get("description").toString();

    CreateIssuepayload mypojo = new CreateIssuepayload(project, issuetype, description, summary);

    Fields f = new Fields(mypojo);

    RestAssured.baseURI = "http://localhost:8080";
    Response res =
            given()
            .header("Content-Type", "application/json")
            .header("cookie", "JSESSIONID=" + Basic.sessionGen() + "").body(f).expect()
            .body(containsString("greeting"))
            .when().post("/rest/api/2/issue")
            .then().extract().response();
}

如果您按如下方式更改 json 文件，您可以使用 Gson

轻松完成此操作

{
  "summary": "Please look into issue",
  "description": "Unable to create my JIRA ticket 3",
  "issuetype": {
    "name": "Bug"
  },
  "project": {
    "key": "BP"
  }
}

而且您也不需要添加 @JsonProperty() 注释。

然后使用Gson将json对象反序列化为Java对象

@Test(enabled = false)
public static void test1() throws JsonProcessingException {

    Gson gson = new Gson();
    CreateIssuepayload mypojo = null;
    
    try {
        BufferedReader bf = new BufferedReader(new FileReader("createissue.json"));
        mypojo = gson.fromJson(bf, CreateIssuepayload.class);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
    
    RestAssured.baseURI = "http://localhost:8080";
    Response res = given()
            .header("Content-Type", "application/json")
            .header("cookie", "JSESSIONID=" + Basic.sessionGen() + "")
            .body(mypojo).expect()
            .body(containsString("greeting")).when().post("/rest/api/2/issue").then().extract().response();

}
