I'm using dcramer's fork of django-paypal, but I always encounter an invalid IPN while working with my sandbox accounts.
I receive the following IPN:
Invalid postback. (INVALID)
I tried everything that showed up on google:
checked seller & buyer emails
sandbox accounts are both verified
I use form.sandbox to render the paypal form
tried removing custom values
there is no non-ascii character in the request
When manually checking the request with https://www.sandbox.paypal.com/cgi-bin/webscr, I also get INVALID.
Did someone encounter this issue ? Is there any more-verbose page to validate ipn requests ?
Yes, I also get errors on post-back starting yesterday (18 June):
Opened POST Back Socket to PayPal.
PayPal Post Back returns HTTP/1.0 400 Bad Request

I use my own IPN integration. It tries to handle all replies from PayPal, which is why I get the last message (: not handled.) I made a package upgrade yesterday, so I'm not quite sure it is a PayPal problem though.

I created a test to fill my SNS dead letter queue to help me develop code to read from this queue. Long story short, I thought an HTTP error would be easiest to simulate failures, but surprisingly, they seem to be counted as success.
In case I am doing it wrong and for the benefit of anyone else who wants to try this out, here is my methodology. I created an HTTP/s endpoint specifically for this test using a bash one liner:
while true; do echo -e "HTTP/1.1 200 OK\n" | nc -Nl 9078; echo "" && date; done
So far so good. I decided that returning a 401 code might be easiest. Capturing a 401 page output with netcat:
HTTP/1.1 401 Unauthorized
Server: nginx/1.21.0
Date: Wed, 01 Sep 2021 12:22:03 GMT
Content-Type: text/html

<head><title>401 Authorization Required</title></head>
<body>
<center><h1>401 Authorization Required</h1></center>
<hr><center>nginx/1.21.0</center>
</body>
</html>
I altered my one liner accordingly:
while true; do echo -e "$(cat 401error)\n" | nc -Nl 9078; echo "" && date; done
I verified that visiting this page in Firefox would pop up a password dialog.
Come test time, SNS blunders along and delivers the message without fear. The message never appears in the DLQ:

Does anyone know? Nothing so far uncovered in duckduckgoing "http code" sns. If I can capture some other codes (403,500,etc) using netcat, I thought it might be useful to know which, if any, are honored.
Any status code outside of the range 200 - 499 will be considered as a failure and retried according to your retry policy as per https://docs.aws.amazon.com/sns/latest/dg/sns-message-delivery-retries.html. Once the max number of retries has been exhausted, the message will be delivered to a DLQ if one is configured.
My Angular4 app (running on http://127.0.0.1:4200 development server) is supposed to access a django REST backend on the web. The backend is under my control and is available only via HTTPS (running Apache that tunnels the request to a gunicorn server running on an internal port). Let's say that this is https://example.com/. For historical reasons, logging the user in is done using sessions, because I want the users to be able to also use Django's admin interface after they logged in. The workflow is as follows:
Users opens http://127.0.0.1:4200, I perform a GET request to https://example.com/REST/is_logged_in which returns a 403 when the user isn't logged in via sessions yet, 200 otherwise. In the former case, the user is redirected to https://example.com/login/, rendered by Django's template engine, allowing the user to log in. Once logged in, the user is redirected to http://127.0.0.1:4200
When clicking on some button in my Angular UI, a POST request is performed. This post request fails with 403, even though the preflight OPTIONS request explicitly lists POST as allowed actions.
Here is my CORS configuration in Django:
NG_APP_ABSOLUTE_URL = 'http://127.0.0.1:4200'
# adapt Django's to Angular's presumed XSRF cookie/header names
CSRF_COOKIE_NAME = "XSRF-TOKEN"
CSRF_HEADER_NAME = "HTTP_X_XSRF_TOKEN"
CORS_ORIGIN_WHITELIST = (
urlparse(NG_APP_ABSOLUTE_URL).netloc
)
CSRF_TRUSTED_ORIGINS = (
urlparse(NG_APP_ABSOLUTE_URL).netloc
)
CORS_ALLOW_HEADERS = default_headers + (
'x-xsrf-token',
)
CORS_ALLOW_CREDENTIALS = True
This is what Chrome reports for the (successful, 200) first REST GET request to check whether the user is logged in (after he successfully did) in the response:
Access-Control-Allow-Credentials:true
Access-Control-Allow-Origin:http://127.0.0.1:4200

Why wouldn't this request work? It makes little sense to me!
Best regards!
I had the same problem, trying to send a POST request to Django (port 8000) from my Angular CLI (port 4200). I thought it was a problem of Django so I installed cors package however the "problem" is with the browser (actually is not a problem, it is a security issue, see here). Anyway, I solved the problem adding a proxy rule for my Angular CLI, as follows:
First, instead of sending my requests to http://localhost:8000/api/... is send them to /api/ (i.e. to my ng server running at port 4200).
Then I added a file in my Angular project called "proxy.conf.json" with the following content:
{
"/api": {
"target": "http://localhost:8000",
"secure": false
}
}
Finally, run your ng server with the flag "--proxy-config":
ng serve --watch --proxy-config proxy.conf.json
All API requests will be sent to the port 4200 and Angular will internally redirect them to Django, avoiding the CORS problem.
Note that this is only valid for development and won't be used when you build your app code and add it as the static code of your Django server.
Finally, with this solution I didn't need anymore the python module for cors so you could remove it.
I am new to Load runner , Am facing am issue while play back of the script
LR 12.50
O.S Windows 7 SP2
Protocol is Mobile HTTP/HTML
Recording mode is Proxy
Let me explain my scenario
While executing following function:
web_custom_request("authenticate",
"URL=https://ws-xx.xxx.com/tcs/rest/authenticate?include=user,company",
"Method=POST",
"Resource=0",
"RecContentType=application/json",
"Referer=",
"Snapshot=t1.inf",
"Mode=HTTP",
"EncType=application/json",
"Body={\"password\":\"xxx\",\"username\":\"xxx\",\"version\":\"1.0.40\"}",
LAST);
For the above POST method , am getting response as below
HTTP/1.1 200 OK\r\n
Date: Tue, 13 Oct 2015 19:19:21 GMT\r\n
Server: Apache-Coyote/1.1\r\n
Content-Type: application/json\r\n
Set-Cookie: dtCookie=DBE9311E44E5C47902702DC762030583|TXlBcHB8MQ; Path=/;
Domain=.xxx.com\r\n
Connection: close\r\n
Transfer-Encoding: chunked\r\n
Which is fine ,Now the second custom request is shown below
web_custom_request("profiles",
"URL=https://ws-test.xxx.com/tcs/rest/profiles",
"Method=GET",
"Resource=1",
"RecContentType=application/json",
"Referer=",
"Snapshot=t2.inf",
LAST);
For the above GET requests in the replay logs am getting:
401 unauthorized error.

{"errors":[{"message":"Authentication required to access endpoint","status":"401","code":"

I refereed this link.
My understanding from the above custom request , login is success but the next
subsequent requests are getting failed.
I have used web_cleanup_cookies() function but didn't solve the issue .
I tried to capture the Cookie ID using the below function
web_reg_save_param("COOKIE_ID",
"LR= Cookie: dtCookie=" ,
"RB= |TXlBcHB8MQ\r\n",
"Ord=All",
"RelFrameId=1",
"Search=All",
LAST);
web_add_header("Cookie",lr_eval_string("{COOKIE_ID}"));
Now question is where to place parameter "COOKIE_ID" in my script while there is
no value in script for COOKIE_ID?
How to handle this issue ? Can anybody please help me .
Please add below headers to the script
web_set_sockets_option("SSL_VERSION","TLS");
web_set_user("username", "password", "domain:portno" );
web_set_sockets_option("INITIAL_BASIC_AUTH","1");
In Vugen, Select snapshot view and compare both record and replay requests, suspecting there might be a missing of header in replay request.
If cookie is the only thing changing you can add it by using web_add_cookie function.

If I do a nc 192.168.2.10 8080 and then GET /test/ I get as expected a JSON response:

Anyone an idea where the problem could be?
As Nick Johnson said in his comment, try a tool that forms requests properly for you.
Another common source of these sorts of errors is trying to parse a GET request on the server (for arguments or whatever) while you're getting a post request.
Also something that always gets me, but that's a 403, is csrf protection. Remember to turn it off for requests you want to make via curl and similar :)
