如何实现模拟HTTP请求调用controller的代码

@RunWith(SpringRunner.class)
@WebMvcTest(MyController.class)
public class MyControllerTest {
  @Autowired
  private MockMvc mockMvc;
  /**
   * 测试方法
   */
  private void bindAndUnbindTenantPoiTest() throws Exception {
    MvcResult mvcResult = mockMvc.perform(post(${"访问的url"})
        .param("${key1}", "${value1}")
        .param("${key2}", "${value2}")
        .param("${key3}", "${value3}")) 
        .andDo(print()) // 定义执行行为
        .andExpect(status().isOk()) // 对请求结果进行验证
        .andReturn(); // 返回一个MvcResult
    jsonObject = toJsonObject(mvcResult);
    assert jsonObject.getIntValue("code") == code; // 断言返回内容是否符合预期
    assert message.equals(jsonObject.getString("message"));
  }  
}

/**
     * Add a request parameter to the {@link MockHttpServletRequest}.
     * <p>If called more than once, new values get added to existing ones.
     * @param name the parameter name
     * @param values one or more values
     */
    public MockHttpServletRequestBuilder param(String name, String... values) {
        addToMultiValueMap(this.parameters, name, values);
        return this;
    }

    /**
     * Add a map of request parameters to the {@link MockHttpServletRequest},
     * for example when testing a form submission.
     * <p>If called more than once, new values get added to existing ones.
     * @param params the parameters to add
     * @since 4.2.4
     */
    public MockHttpServletRequestBuilder params(MultiValueMap<String, String> params) {
        for (String name : params.keySet()) {
            for (String value : params.get(name)) {
                this.parameters.add(name, value);
            }
        }
        return this;
    }
