我正在学习 reactor-netty 作为 http 客户端来发送多表单数据。 我的服务器需要
Content-Length
字段,但似乎 reactor-netty 没有自动设置它。(有趣的是它在每个部分都设置了 Content-Length
,这不满足我的服务器)
HttpClient.create().port(server.port()).post().uri("/postpath")
.sendForm((req, form) -> form
.multipart(true)
.file("a", new ByteArrayInputStream(jsona.getBytes(StandardCharsets.UTF_8)), "application/json")
.file("b", new ByteArrayInputStream(jsonb.getBytes(StandardCharsets.UTF_8)), "application/json")
)
//...omitted, same as the github examples
Http traffic is like following:
POST /post HTTP/1.1
user-agent: ReactorNetty/1.1.4
host: myservernmae
accept: */*
content-type: application/json
content-type: multipart/form-data; boundary=40e3ae2412eea9a2
transfer-encoding: chunked
--40e3ae2412eea9a2
content-disposition: form-data; name="a"
content-length: 94
content-type: application/json
content-transfer-encoding: binary

--40e3ae2412eea9a2
content-disposition: form-data; name="b"
content-length: 205
content-type: application/json
content-transfer-encoding: binary

--40e3ae2412eea9a2--
与 http apache 客户端中的
CloseableHttpClient
相比
final HttpPost httppost = new HttpPost("http://myservernmae/postpath");
final HttpEntity reqEntity = MultipartEntityBuilder.create()
.addPart("a", aBody)
.addPart("b", bBody)
.build();
httppost.setEntity(reqEntity);
final CloseableHttpClient httpclient = HttpClients.createDefault();
httpclient.execute(httppost, response -> {
// omit remaining
POST /post HTTP/1.1
Accept-Encoding: gzip, x-gzip, deflate
Content-Length: 611
Content-Type: multipart/form-data; charset=ISO-8859-1; boundary=dbiD5AN62qhyG8C8HAbOPu5zlltTOSu2q
Host: myservernmae
Connection: keep-alive

谁能告诉我怎么设置
Content-Length
?自动更好。我正在使用 jdk11,reactor-netty 1.1.4.
