使用放心放置方法测试 api 时出现错误请求 400 和反序列化错误

Question

我正在使用路径 para 和查询 para 测试端点，并使用一些参数更新请求。当我发送请求内容类型是 json 并且请求看起来很好与我试图更改的数据但是当收到响应时

内容类型是文本，我收到 400 错误错误请求作为状态代码和错误消息

javax.ws.rs.ProcessingException：RESTEASY008200：JSON 绑定反序列化错误：javax.json.bind.JsonbException：无法推断解组类型：java.util.List

我的代码

@Given("^api is set up with required details$")

public void api_is_set_up_with_user_data() throws Throwable {

    loadProp();

    base_url = prop.getProperty("baseurl");

    RestAssured.baseURI = base_url;

}

@When("^a user retrieves the preferences by userid \"([^\"]*)\" and type \"([^\"]*)\"$")

public void a_user_retrieves_the_preferences_by_userid_and_type(String userid, String parameter) throws Throwable {

    request = given().pathParam("user_id", userid).queryParam("type", parameter);

    System.out.println(request);

    ENDPOINT_GET_USER_BY_ID = base_url + "{user_id}/preferences";

    response = request.when().get(ENDPOINT_GET_USER_BY_ID);

    System.out.println("response: " + response.prettyPrint());

}

@Then("^updates the value \"([^\"]*)\" of name \"([^\"]*)\"$")

public void updates_the_value_of_name(String value, String displaytext) throws Throwable {

    HashMap<String,String> post = new HashMap<String,String>();

    post.put("displaytext",displaytext);

    post.put("value",value);

    response = request.contentType("application/json").accept("*/*").body(post).put(ENDPOINT_GET_USER_BY_ID);

//        response = request.header("Content-Type", "application/json").body(post).put(ENDPOINT_GET_USER_BY_ID);

    System.out.println("Response : " + response.asString());

    System.out.println("Statuscode : " +response.getStatusCode());

}

正如您在那里的评论中所分享的那样，端点需要一个对象列表，而不是您发送的单个对象......只需尝试用列表包装它，您就会遇到 400 错误。您要发送的内容；{&nbsp; &nbsp; "displayText": "Warrants",&nbsp;&nbsp; &nbsp; "value": "true"&nbsp; // I don't know about this value field here}正如您所分享的那样，预期是什么；[&nbsp;&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; "displayText": "",&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; "preferences": [ { "category": "", "displaytext": "", } ],&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; "priority": "20"&nbsp;&nbsp; &nbsp; }]&nbsp;一个问题是您必须在列表中发送对象，同时将对象作为映射传递也会适得其反，最好使用 RQ 中使用的相同对象。public class Request {&nbsp; &nbsp; private String displayText;&nbsp; &nbsp; private List<Preference> preferences;&nbsp; &nbsp; private Integer priority;&nbsp; &nbsp; //getter, setter,etc}& 在您的身体中放心使用它；List<Request> requestList = new ArrayList<>();Request request = new Request();request.setDisplayText("etc");... // set other stuffrequestList.add(request);response = request.contentType("application/json").accept("*/*").body(requestList).put(ENDPOINT_GET_USER_BY_ID);
