Hi,
I am getting a ClientProtocolException for a delete request. The response
is "204 No Content" and seems to be a bug in httpclient.
I am creating the transport like this
transport = new ApacheHttpTransport();
final RequestConfig defaultRequestConfig = RequestConfig.DEFAULT;
final RegistryBuilder<ConnectionSocketFactory> builder =
RegistryBuilder.<ConnectionSocketFactory>create()
.register("http",
PlainConnectionSocketFactory.getSocketFactory());
// allow a customized SSLConnectionSocketFactory to be used
if (this.sslConnectionSocketFactory != null) {
builder.register("https", this.sslConnectionSocketFactory);
} else {
builder.register("https",
SSLConnectionSocketFactory.getSocketFactory());
}
final Registry<ConnectionSocketFactory> registry = builder.build();
final PoolingHttpClientConnectionManager cm =
new PoolingHttpClientConnectionManager(registry);
// Increase max total connection
cm.setMaxTotal(this.maxConnections);
// Increase default max connection per route
cm.setDefaultMaxPerRoute(this.maxConnections);
//close expired connections
cm.closeExpiredConnections();
final HttpClient client = HttpClientBuilder.create()
.setConnectionManager(cm)
.setDefaultRequestConfig(defaultRequestConfig)
.setMaxConnPerRoute(this.maxConnections)
.setConnectionReuseStrategy(
DefaultConnectionReuseStrategy.INSTANCE)
.build();
transport.setClient(client);
transport.setServerUrl(serverUrl);
transport.setUsername(username);
transport.setPassword(password);
transport.setBasicAuth(hasText(username) || hasText(password));
return transport;
and calling transport.delete(httpparams) and the server it is trying to
call seem to be fine no stack trace and access log seems behave as expected.
I enabled some debug logging which is indicating that there might be a bug
with the library
