我有以下工作示例

val headers = HttpHeaders()
headers.add("Content-Type", "application/merge-patch+json")  

mockMvc.perform(
        patch(path)
            .headers(headers)
            .content(objectMapper.writeValueAsString(patchRequest)),
    ).andExpect(status().isOk)
        .andReturn()

我想用KotlinDSL重写它

val result = mockMvc.patch(path) {
        //this.header = headers
        content = objectMapper.writeValueAsString(patchRequest)
    }.andExpect{ status { isOk() } }
        .andReturn()

我不知道如何传递自定义头。有办法吗？
