Question

我有一个Angular前端，它调用Java Spring Boot后端API。前端多次将以下请求发送到后端，但是其中一些失败，状态码为 400 。记录的错误为org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing。但是，当我查看Chrome中的 Network 标签时，请求看起来很不错，如果我再次发送它，它就成功了。但是最奇怪的是，如果我通过 curl 调用它，它永远不会失败。

前端：

const endpoint = 'BACKEND_URL/settings';
const data = [{"id":123,"settings":"SETTINGS"}];
const headers = {
  'Content-Type': 'application/json; charset=UTF-8',
  'Authorization': 'ACCESS_TOKEN'
};
const params = {};

axios.post(endpoint, data, { headers, params })
  .then(function (response) {
    console.log(response.status, response.data);
  })
  .catch(function (error) {
    console.log('error', error.response.status);
  });

后端：

@Api(tags = "API name", description = "API description")
@RestController
@RequestMapping("/")
public class SettingsController {

    @ApiOperation("Endpoint name")
    @PostMapping(path = "/settings", consumes =     MediaType.APPLICATION_JSON_UTF8_VALUE, produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
    @Transactional
    public ResponseEntity<Boolean> updateSettings(@RequestBody @ApiParam("description") List<Settings> settings) throws ApiException {
        // unreachable code when there is no body
    }
}

使用卷曲呼叫：

curl -X POST \
  BACKEND_URL/settings \
  -H 'Authorization: ACCESS_TOKEN' \
  -H 'Content-Type: application/json' \
  -d '[{"id":123,"settings":"SETTINGS"}]'

可能您需要使用字符串格式（而不是数组格式）在主体部分中发送数据，是否可以尝试使用以下代码-

const data = [{"id":123,"settings":"SETTINGS"}];
....

axios.post(endpoint, JSON.stringify(data), { headers, params })
....

POST请求无主体发送
