我正在尝试使用Springboot-Reactive webclient进行HTTP调用。我正在通过远程服务器错误关闭连接。
请找到以下使用Webclient进行剩余呼叫的代码。
Mono<String> post(String url, JSONObject body) {
Mono<String> result = webClient().post().uri(url)
.contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON_UTF8)
.body(BodyInserters.fromObject(body))
.exchange().log()
.flatMap { clientResponse ->
return clientResponse.bodyToMono(String.class)
}
return result
}
Webclient创建的代码：
WebClient webClient() {
TcpClient tcpClient = TcpClient.create()
.option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 30000)
.doOnConnected { connection ->
connection.addHandlerLast(new LoggingHandler(LogLevel.TRACE))
connection.addHandlerLast(new ReadTimeoutHandler(30))
.addHandlerLast(new WriteTimeoutHandler(30))
}
tcpClient.wiretap(true)
ReactorClientHttpConnector httpConnector = new ReactorClientHttpConnector(HttpClient.from(tcpClient))
return WebClient.builder()
.clientConnector(httpConnector)
.build()
}
第一次通话后，我收到以下日志：
