VERTX HTTP请求的奇怪问题
我在AWS上配置了HTTPS网站，该网站允许从IP的白色列表中访问。 我的本地机器以VPN连接在白色列表中运行。 我可以从Web浏览器或Java.net.http软件包访问该网站，并带有以下代码：
HttpClient client = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder()
.uri(URI.create("https://mywebsite/route"))
.GET() // GET is default
.build();
HttpResponse<Void> response = client.send(request,
HttpResponse.BodyHandlers.discarding());
但是，如果我从io.vertx.ext.web.client软件包中替换了代码，我得到了403的禁止响应来自同一网站。
WebClientOptions options = new WebClientOptions().setTryUseCompression(true).setTrustAll(true);
HttpRequest<Buffer> request = WebClient.create(vertx, options)
.getAbs("https://mywebsite/route")
.ssl(true).putHeaders(headers);
request.send(asyncResult -> {
if (asyncResult.succeeded()) {
HttpResponse response = asyncResult.result();
}
});
有人知道为什么VERTX实现被拒绝吗？
I configured an HTTPS website on AWS, which allows visiting from a white list of IPs.
My local machine runs with a VPN connection, which is in the white list.
I could visit the website from web browser or by the java.net.http package with the below code:
HttpClient client = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder()
.uri(URI.create("https://mywebsite/route"))
.GET() // GET is default
.build();
HttpResponse<Void> response = client.send(request,
HttpResponse.BodyHandlers.discarding());
But if I replaced the code with a Vertx implementation from io.vertx.ext.web.client package, I got a 403 forbidden response from the same website.
WebClientOptions options = new WebClientOptions().setTryUseCompression(true).setTrustAll(true);
HttpRequest<Buffer> request = WebClient.create(vertx, options)
.getAbs("https://mywebsite/route")
.ssl(true).putHeaders(headers);
request.send(asyncResult -> {
if (asyncResult.succeeded()) {
HttpResponse response = asyncResult.result();
}
});
Does anyone have an idea why the Vertx implementation is rejected?

终于有根本原因。我启动了一个本地服务器，该服务器接受测试请求并将其转发到AWS上的服务器。测试客户端将请求发送到Localhost，因此在请求标题中“ host = localhost：8080/...”。在Vert.x实施中，将错误的标题输入“ host = localhost：443/...”被错误地放入请求标题中。我没有调试Vert.x实现，所以我不知道为什么它会这样做。但是随后，AWS防火墙拒绝了该请求，该请求的规则是请求不能来自Localhost。
Finally got the root cause. I started a local server that accepts the testing request and forwards it to the server on AWS. The testing client sent the request to localhost and thus "Host=localhost:8080/..." is in the request header. In the Vert.X implementation, a new header entry "Host=localhost:443/..." is wrongly put into the request headers. I haven't debug the Vert.X implementation so I have no idea why it behaviors as this. But then the AWS firewall rejected the request with a rule that a request could not come from localhost.
