I am trying to make a small HTTP server in Ruby. Its just meant to learn how stuff works, nothing big. So what i did is to send the server an ajax request. The server is listening on port 2000, and so the ajax request is also on port 2000.
The problem i am facing is that the ajax request is returned only with the headers, the content is missing. I tried everything i could find, but it seems to fail too...
I have attached the code, for you to take a look
require 'socket' # Get sockets from stdlib
server = TCPServer.new(2000) # Socket to listen on port 2000
loop { # Servers run forever
client = server.accept # Wait for a client to connect
headers = "HTTP/1.1 200 OK\r\nDate: Tue, 14 Dec 2010 10:48:45 GMT\r\nServer: Ruby\r\nContent-Type: text/html; charset=iso-8859-1\r\n\r\n"
client.puts headers # Send the time to the client
client.puts "<html>amit</html>"
client.close # Disconnect from the client
}
The ajax request is working when pointed to a PHP script running on Apache. the only problem seems to occur when using this server.
Any help is as always, deeply appreciated :)

Amit
Your code works fine.
$ telnet localhost 2000
HTTP/1.1 200 OK
Date: Tue, 14 Dec 2010 10:48:45 GMT
Server: Ruby
Content-Type: text/html; charset=iso-8859-1
<html>amit</html>
Connection to host lost.
Now you'll have to find out what's wrong with your AJAX request...
I also included the Content-Length header and that seemed to clear up the errors I was getting with curl:
require 'socket' # Get sockets from stdlib
server = TCPServer.new(2000) # Socket to listen on port 2000
loop { # Servers run forever
client = server.accept # Wait for a client to connect
resp = "<html>amit</html>"
headers = ["HTTP/1.1 200 OK",
"Date: Tue, 14 Dec 2010 10:48:45 GMT",
"Server: Ruby",
"Content-Type: text/html; charset=iso-8859-1",
"Content-Length: #{resp.length}\r\n\r\n"].join("\r\n")
client.puts headers # Send the time to the client
client.puts resp
client.close # Disconnect from the client
}
You're missing the Access-Control-Allow-Origin HTTP header in your response headers.
Since you're trying an AJAX request, and it is basically an XHTTPRequest, you need to pass it in the response to the client, in order to accomplish the Cross-Origin Resource Sharing implementations of your browser.
Just add in your HTTP server:
headers = "HTTP/1.1 200 OK\r\n"
headers += "Access-Control-Allow-Origin: *\r\n"
headers += "Date: Tue, 14 Dec 2010 10:48:45 GMT\r\nServer: Ruby\r\nContent-Type: text/html; charset=iso-8859-1\r\n\r\n"
and then you can try to see if works.

I am using SIM800 to send HTTP Post request to a remote InfluxDB database. I have successfully sent HTTP Post request to the database from my computer using Curl as shown below.
01:~$ curl -i -XPOST 'http://<ip address>:8086/write?db=mydb' --data-binary 'location,host=server01,region=us-west value=0.99'
HTTP/1.1 204 No Content
Content-Type: application/json
Request-Id: 3c958273-edb2-11eb-88ca-000000000000

Date: Mon, 26 Jul 2021 01:38:54 GMT
After that when I tried using SIM800, I received 400 Bad Request after executing AT+HTTPACTION=1 . The remote server responded with "+HTTPACTION: 1,400,0" . Below are the AT Commands.
AT+SAPBR=3,1,"CONTYPE","GPRS"
AT+SAPBR=3,1,"APN","myAPN"
AT+SAPBR=1,1
AT+HTTPINIT
AT+HTTPPARA="CID",1
AT+HTTPPARA="URL","http://<ip address>:8086/write?db=mydb"
AT+HTTPPARA="CONTENT","application/json"
AT+HTTPPARA="USERDATA","location,host=server01,region=us-west value=0.55"
AT+HTTPDATA=300,5000
AT+HTTPACTION=1
AT+HTTPREAD
AT+HTTPTERM
AT+SAPBR=0,1
Besides that, i captured the packets when SIM800 sent http post request but could not find the http post body.
The http post body can be seen in the captured packets when sending http post using Curl.
I appreciate if anyone can shed some light on this matter. Thank you in advance.
I managed to get it to work. Here are the AT commands:-
AT+SAPBR=3,1,"CONTYPE","GPRS"
AT+SAPBR=3,1,"APN","myAPN"
AT+SAPBR=1,1
AT+HTTPINIT
AT+HTTPPARA="CID",1
AT+HTTPPARA="URL","http://<ip address>:8086/write?db=mydb"
AT+HTTPPARA="CONTENT","application/json"
AT+HTTPDATA=48,5000
location,host=server01,region=us-west value=0.55
AT+HTTPACTION=1
AT+HTTPREAD
AT+HTTPTERM
AT+SAPBR=0,1
after executing the AT+HTTPDATA, quickly execute the HTTP data (location,host...).
I'm trying to test an API Get method when I run the same API for 1000 records in postman the response time is 4 seconds (installed postman in windows 7 and ran the test), whereas in JMeter it is taking 22 seconds, any idea what might be the reason for this?
Steps followed for JMeter run:
GUI mode
Non-GUI mode
Both Postman and JMeter are in same system/network.
Below is the Jmeter result:

You need to compare similar request. In your case at least 1 header is missing. Add to JMeter's HTTP Header Accept-Encoding gzip,deflate
Follow JMeter's Best Practices to get the best performance, the main one is not to use listeners:
Use non-GUI mode: jmeter -n -t test.jmx -l test.jtl
Use as few Listeners as possible; if using the -l flag as above they can all be deleted or disabled.
I am unable to even get CI's welcome page to come up on OpenShift - likely because of https. I checked my config file and it detects HTTPS and produces a correct base_url:
$config['base_url']="https//mysite.rhcloud.com/CI_base/";
But that seems to be as far as it goes - nothing in the response to CI's GET call. (I don't have a .htaccess set up. )
GET /CI_base/index.php
When I compare this to the GET request on my localhost system (over http), I noticed that the headers were a little different. But I can't tell which ones may be pointing to a culprit. The issue is probably jumping out at you - at least I hope so! Please could point me in the right direction?
Thanks!

by default your application on Openshift responds to both http and https. For instance, if you use the following Codeigniter quickstart https://github.com/openshift/CodeIgniterQuickStart, you can go to http://ci-$yournamespace.rhcloud.com and https://ci-$yournamespace.rhcloud.com. To route to https by default take a look at this article here: https://help.openshift.com/hc/en-us/articles/202398810-How-to-redirect-traffic-to-HTTPS-
I'm currently attempting to write a basic client that listens to events from (enterprise) github, and makes API calls accordingly.
The problem I have is that I can't manage to get the PubSubHubbub client configured. I thought it was the client/authentication I'm using, but I now can't get the basic call from the docs working!
In an attempt to work out what I'm doing wrong, I'm making a curl request to my normal github account:
curl -u "joepym" -i \
https://api.github.com/hub \
-F "hub.mode=subscribe" \
-F "hub.topic=http://github.com/JoePym/faraday/events/push" \
-F "hub.callback=*callbackurl*"
and I'm getting back
HTTP/1.1 100 Continue
HTTP/1.1 422 Unprocessable Entity
Server: GitHub.com
Date: Wed, 08 May 2013 18:13:24 GMT

"message": "Invalid event: nil"
}
This invalid event message is what my main client is also getting when I attempt to call my enterprise github account with enterprise credentials.
Has anyone encountered this before?
Try using https://github.com/JoePym/faraday/events/push as your hub.topic. Note that we are now using 'https'.
I can browse the page by browser, but I can't download the html page by wget.
https://money.benck.tw
When I use wget, it can't even connect to the website:

However, I can download the other https website like: https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js
It's very weird.
For this website you have to use the --no-check-certificate command
wget --no-check-certificate https://money.benck.tw
I'm experiments the same issue, I trying to download files from an external site like https://downloads.wordpress.org/plugin/easy-wp-smtp.zip and I wget using --no-check-certificate stills not working.... It's freezing in this line:
Connecting to downloads.wordpress.org (downloads.wordpress.org)|198.143.164.250|:443...
Anyone have the same issue?
No IP tables configured and rules. When I do this on other server on the same networks works fine. This only happens on this server specialy.

This is because of this page is probably scraped by wget too often. You need to modify headers, especially useragent.
Examples from other website:
--no-check-certificate does not hepls
wget --no-check-certificate "https://www.money.pl/pieniadze/depozyty/walutowearch/1921-02-05,2021-02-05,LIBORCHF3M,strona,1.html" --2021-02-05 17:05:34-- https://www.money.pl/pieniadze/depozyty/walutowearch/1921-02-05,2021-02-05,LIBORCHF3M,strona,1.html
