无法解析对象，因为未在响应中指定未支持的Content-Type。 内容类型为'text / html; charset = utf-8'

Question

我正在尝试运行以下Junit测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { TestConfig.class, Account.class, AccountDao.class }, loader = AnnotationConfigContextLoader.class)
public class AccountTest{


    private static final String URL_PREFIX = "http://localhost:8080/dsp2api";
    private String cookie;

    private RequestSpecification givenAuth() {
        // return RestAssured.given().auth().form("user", "userPass", formConfig);
        // if (cookie == null) {
        // cookie = RestAssured.given().contentType("application/x-www-form-urlencoded").formParam("password", "userPass").formParam("username", "user").post(URL_PREFIX + "/login").getCookie("JSESSIONID");
        // }
        // return RestAssured.given().cookie("JSESSIONID", cookie);
        return RestAssured.given()
            .auth()
            .basic("user", "userPass");
}
    @Test
    public void whenMethodArgumentMismatch_thenBadRequest() {
        Response response = givenAuth().get(URL_PREFIX + "/api/foos/ccc");
        ApiError error = response.as(ApiError.class);

        assertEquals(HttpStatus.BAD_REQUEST, error.getCode());
        assertEquals(1, error.getErreur().length());
    }

}

但是当我这样做时，出现以下错误：

java.lang.IllegalStateException: Cannot parse object because no supported Content-Type was not specified in response. Content-Type was 'text/html;charset=utf-8'.

我基于我的测试的ErrorApi是这个：

public class ApiError {

    private HttpStatus code;
    private String erreur; 
    private String description;

    public ApiError() {

    }

    public ApiError(HttpStatus code, String erreur, String description) {
        this.code = code;
        this.erreur = erreur;
        this.description = description;
    }

    public HttpStatus getCode() {
        return code;
    }

    public void setCode(HttpStatus code) {
        this.code = code;
    }

    public String getErreur() {
        return erreur;
    }

    public void setErreur(String erreur) {
        this.erreur = erreur;
    }

    public String getDescription() {
        return description;
    }

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


}

这是我的异常处理程序：

@ControllerAdvice
public class RestExceptionHandler extends ResponseEntityExceptionHandler{

    @Override
    protected ResponseEntity<Object> handleMissingServletRequestParameter(
      MissingServletRequestParameterException ex, HttpHeaders headers, 
      HttpStatus status, WebRequest request) {
        String error = ex.getParameterName() + " Requête invalide";

        ApiError apiError = 
          new ApiError(HttpStatus.BAD_REQUEST,ex.getLocalizedMessage(), error );
        return new ResponseEntity<Object>(apiError, new HttpHeaders(), apiError.getCode());
    }

}

我现在想知道的是，在哪里可以指定内容类型（json），以便此错误消失？

在此先感谢您的帮助。

更新1 ：

更改了以下行：

Response response = givenAuth().get(URL_PREFIX + "/api/foos/ccc");

至：

Response response = givenAuth().log().all().header("ContentType","application/json").when().get(URL_PREFIX);

但这并不能解决问题。

您的网址应该有问题。 服务不可用或服务URL错误。 尝试使用POSTMAN触发相同的请求，以确认您的请求和服务没有问题。
