英文:
Vertx Streaming csv file/data to http response
问题
以下是您要翻译的内容：
我想在Vertx API响应中将一些数据作为CSV文件返回给DB。我一直在遵循此链接，但我无法返回正确的CSV文件作为API响应。
我的代码：
rc.response()
.putHeader("Content-Type", "application/csv")
.putHeader("Content-Disposition", "attachment; filename=stream_wide.csv")
.putHeader(HttpHeaders.TRANSFER_ENCODING, "chunked")
.setChunked(true);
getDataFromDB()
.subscribe(
rs -> rc.response().write(rs, "UTF-8"),
ex -> {ex.printStackTrace(); logger.error("exception encountered " + ex.getMessage());},
() -> {rc.response().end(); rc.response().close();});

你遇到了什么错误/行为？
尝试使用来自CSV文件的字节创建缓冲区。
byte [] csvBytes = <一些从结果集中提取表示CSV文件的字节的方法>
response.end(Buffer.buffer(csvBytes));
英文:
What kind of error/behavior are you getting?
Try creating a Buffer with the bytes from the CSV file.
byte [] csvBytes = <some method extracting the bytes representing the csv file from the result set>
response.end(Buffer.buffer(csvBytes));
