HttpClient httpclient = HttpClientBuilder.create().build();

HttpPost request = new HttpPost("http:url/configurations");
request.setHeader(HttpHeaders.AUTHORIZATION, authHeader); request.setHeader("Content-type", "application/json");
StringEntity entity = new StringEntity(SIDate);

这是我的Java程序，用于设置SIDate（有效负载/请求参数）中提到的标志。当我对NL_EAMP_NL1392（tsr_id）进行硬编码时，发布请求工作正常。但我声明并将其作为变量传递，却遇到Bad Request 400错误。如何传递tsr_id而不是NL_EAMP_NL1392来请求参数。 TIA
