SimpleHttpRequest | c http client for simple rest requests | REST library

I have a small sample servlet deployed to a Tomcat that will echo back any received parameters. The Tomcat is configured to support HTTP/1.1 and HTTP/2. I can use curl to make GET requests to the servlet demonstrating it works over both HTTP/1.1 and HTTP/2.

Using the Apache HTTP 5.0 client I have a unit test to hit the servlet and POST a request with some parameters (request content) that works fine - the server receives the parameters and returns them back to the client where I can read them. In this test I call the client to use HTTP/1.1 or HTTP/2 using the CloseableHttpAsyncClient.setVersionPolicy() call. However, if I change to use HTTP/2 then the client does not send the request content to the server.

Below is the example code for a successful HTTP/1.1 call - you can see I have setVersionPolicy(HttpVersionPolicy.FORCE_HTTP_1). If I change that to FORCE_HTTP_2 then the call is made over HTTP/2.0 but the request content is not sent.

Can anyone suggest what I am doing wrong or what extra I need to do? I have not found a lot of documentation on the use of the new Apache 5.0 client libraries, and the examples do not show sending and POST content (or at least those I can find).

• I'm a Software Engineer in Test running order permutations of Restaurant Menu Items to confirm that they succeed order placement w/ the POS
  • In short, this POSTs a JSON payload to an endpoint which then validates the order w/ a POS to define success/fail/other
  • Where POS, and therefore Transactions per Second (TPS), may vary, but each Back End uses the same core handling
  • This can be as high as ~22,000 permutations per item, in easily manageable JSON size, that need to be handled as quickly as possible
  • The Network can vary wildly depending upon the Restaurant, and/or Region, one is testing
    • E.g. where some have a much higher latency than others
  • Therefore, the HTTPClient should be able to intelligently negotiate the same content & endpoint regardless of this

• I'm using Apache's HTTP Client 5 w/ PoolingAsyncClientConnectionManager to execute both the GET for the Menu contents, and the POST to check if the order succeeds
• This works out of the box, but sometimes loses connections w/ Stream Refused, specifically:
  • org.apache.hc.core5.http2.H2StreamResetException: Stream refused
• No individual tuning seems to work across all network contexts w/ variable latency, that I can find
• Following the stacktrace seems to indicate it is that the stream had closed already, therefore needs a way to keep it open or not execute an already-closed connection

I wanted to know how to add rows of data to the master detail table but not using an external json file and just write the row records inline via the JS

Anyone have any idea on how to go about this

I am trying to add favorites by following this instruction, but I cannot get the title to be read from the strings file. What am I doing wrong?

This is my getExtendedMetadata response:

I'm trying to create multiple asynchronous HTTP connections using single client endpoint I have tried the multiplexing example given in Apache site

the code snippet is as follows,

I am trying to run a simple test on a remote JMeter 4.0 server from a JMeter 4.0 client.
Both are configured to use the same rmi_keystore.jks. The server starts fine and listens on RMI and Server Engine ports.
When I try to start the client if fails with the java.net.BindException: Address already in use (Bind failed) error. netstat shows that no process is listening on this port.

I need to implement a cancel-able client-side HTTP request in Node.js, without using external libraries. I'm giving a Promise object - cancellationPromise - which gets rejected when the cancellation is externally requested. This is how I know I may need to call request.abort().

The question is, should I be calling request.abort() only if https.request is still pending and response object is not yet available?

Or, should I be calling it even if I already got the response object and am processing the response data, like in the code below? In which case, will that stop any more response.on('data') events from coming?

I'm learning ag-grid to display data into a grid. I've just started with a simple example to display simple data to cell using cellRenderer. You can exam on the code here:

I'm using Apache HttpClient 5 along with Conscrypt to perform simultaneous HTTP 2.0 requests over SSL as shown below:
