当我发送一个post请求时,我得到这个错误。
Caused by: com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'message': was expecting (JSON String, Number, Array, Object or token 'null', 'true' or 'false')

我有这样一个JSON,从客户端发送到服务器。
{
"message": "string",
"originator": "string",
"receivers": "string"
}
这是我的服务层方法,它在那里生成Webclient代码。
@Override
public Mono<ResponseEntity<? extends ResponseResource>> sendSms(BulkSmsRequestResourceTest request) {
if (request == null) {
return Mono.just(new ResponseEntity<>(
new ErrorResponseResource(
"Transaction failed unsuccessfully!",
400),
HttpStatus.BAD_REQUEST));
}
Mono<BulkSmsRequestResourceTest> bulkSmsRequestResourceMono = webClientBuilder.build()
.post()
.uri(sendSmsService)
.contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON)
.body(Mono.just(request), BulkSmsRequestResourceTest.class)
.retrieve()
.bodyToMono(BulkSmsRequestResourceTest.class);
bulkSmsRequestResourceMono.subscribe();
return Mono.just((new ResponseEntity<>(new SuccessResponseResource("Transaction done successfully", 200), HttpStatus.OK)));
}
虽然我得到错误,但数据成功地存储到数据库。
这是我的dto课
@Data
@NoArgsConstructor
@AllArgsConstructor
@Builder
public class BulkSmsRequestResourceTest {
@JsonProperty("message")
private String message;
@JsonProperty("receivers")
private String receivers;
@JsonProperty("originator")
private String originator;
}
这是我的服务器响应代码:
@Override
public String save(BulkSmsRequestDto bulkSmsRequestDto) {
if (bulkSmsRequestDto == null) {
return "message unsuccess sended";
}
BulkSms bulkSms = BulkSms.builder()
.message(bulkSmsRequestDto.getMessage())
.phoneNumber(bulkSmsRequestDto.getReceivers())
.originator(bulkSmsRequestDto.getOriginator())
.build();
this.bulkSmsRepository.save(bulkSms);
return "message success sended";
}

在我看来,你发送的
message
属性根本不是你所调用的服务所期望的。您将
BulkSmsRequestResourceTest
设置为请求正文和响应正文。您确定服务器在请求中需要message
属性,并且在响应中也包含message
吗?您的附加代码只是表明这实际上是正确的。您的服务器使用简单的
String
(“message success sended”)进行响应,但您希望它是一个对象(BulkSmsRequestResourceTest
)。请将您的代码更新为以下代码:q3aa05252#
如果服务器收到了你的请求,并且执行了预期的逻辑,那么问题应该与它的Json响应和你的
BulkSmsRequestResourceTest
类的结构有关。这个错误发生在反序列化过程中,所以你的客户端有一些数据要转换。可能是你的类或对象Map器设置没有正确配置。

我的问题是我需要在前端调用API之前对数据进行
JSON.stringify()
,我猜jquery没有自动完成这个任务
