通过 WebClient 发送 POST 请求，传递复杂的 JSON 正文的问题

问题描述

希望有人能帮助我。

我在 postman.co 网站上准备了一个带有 JSON 正文的 POST 请求，如下所示：

{
    "user": {
        "name": "John Doe","account": {
            "accountId": "1234","mail": "j.doe@mail.com"
        },"address": null
    },"registrationDate": "2021-07-01","text": null,"description": "something","amount": 800,"currency": "EUR","tex1": null,"text2": null
    "anotherObject": {
        "id": null,"isNew": false,"number": "12345","type": "STUDENT","student": {
            "fiscalCode": "XLFGBT34G34V432W","text2": null
        },"teacher": null
    }

}

关于邮递员，一切都相当不错，回复正确。所以我在我的java代码中复制了它，你如何在下面看到：

AccountDTO account = new AccountDTO("1234","j.doe@mail.com");
UserDTO user = new UserDTO("John Doe",account,null);
StudentDTO student = new StudentDTO("XLFGBT34G34V432W",null,null);
AnotherObjectDTO anotherObject = new AnotherObjectDTO(null,false,"12345","STUDENT",student,null);
RequestDTO request = new RequestDTO(user,"2021-07-01","something",800,"EUR",anotherObject);

最后，我使用以下代码来执行我的 POST 请求：

public String postUserinformationById(String accountId,RequestDTO request) {
    return webClient.post()
            .uri(POST_ACCOUNT_informatION,accountId)
            .header("Auth-Schema",AUTH_SCHEMA)
            .header("apikey",API_KEY)
            .accept(MediaType.APPLICATION_JSON)
            .body(BodyInserters.fromValue(request))
            .retrieve()
            .onStatus(HttpStatus::is4xxClientError,response -> {
                System.out.println("4xx error");
                return Mono.error(new RuntimeException("4xx"));
              })
              .onStatus(HttpStatus::is5xxServerError,response -> {
                System.out.println("5xx error");
                return Mono.error(new RuntimeException("5xx"));
              })
            .bodyToMono(String.class)
            .block();
}

但我收到了“Response 400 BAD_REQUEST”。

Encoding [RequestDTO(user=UserDTO(name=John Doe,account=AccountDTO(accountId=1234 (truncated)...]

有人有什么建议吗，我如何检查我是否发送了正确的请求？
