HTTP 400 Bad Request Error - r

I am trying to post a XML file (test1.xml) and receive an output from a webservice API. I get an error HTTP/1.1 400 Bad Request. This is the code below.
myheader=c(Connection="close",
'Content-Type' = "application/xml",
'Content-length' =nchar("test1.xml"))
data = getURL("http://abcd/efg/requests/",
userpwd="m12345:123456", httpauth = 1L,
postfields="test1.xml",
httpheader=myheader,
verbose=TRUE)
This is the output
* Hostname was NOT found in DNS cache

Not sure where I am going wrong, need help ?

If that was indeed exactly what was sent in the Authorization: header for the given user+password then something seriously wrong happened as your combo should've created bTEyMzQ1OjEyMzQ1Ngo=.
The other aspects of the request looks fine so only reading up on the server side requirements for this server and API will give you the answer.

A strange problem about size limit in http header

Context: I maintain a kind of web service server, but with a particular implementation: all data sent by the web services are located in the http header. That means there is only http header in the response (no body part). The web service runs as a windows service. The consumer is my PHP code which invokes the web service via CURL library. All this is in production since 3 years and works fine. I recently had to build a development environment.
I have the web service on a Windows 7 pro, as a windows service.
I have my PHP consumer in another windows 7 pro (WAMP + CURL).
my PHP code invokes the web service and displays the raw response.
in this context the problem occurs: if the response contains more than 1215 characters, I have an empty response (but no error message).
I installed my PHP code (exactly the same) on a new Linux ubuntu: I have the same problem.
I installed my PHP code (exactly the same) on a new Linux centos: I DON'T HAVE THE PROBLEM.
I read a lot on internet about size limitation on http header, and I think today it's not the reason of the problem.
I examined all size limitation parameters on Apache, PHP, Curl but I didn't find something relevant.
If someone has some information. All tracks are welcome. Thanks
not an answer, but want to say that using PHP 7.2.5 under mod_php with Apache 2.4.33, i am unable to reproduce your issue, as i have no problems sending anything from 1 byte to 10,000 to even 100,000 bytes in headers:
here is my producer.php:
<?php
$size=((int)($_GET['s'] ?? 1));
header("X-size: {$size}");
$data=str_repeat("a",$size);
header("X-data: {$data}");
http_response_code(204); // 204 NO CONTENT
and whether i hit http://127.0.0.1/producer.php?s=1 or http://127.0.0.1/producer.php?s=10000 or even http://127.0.0.1/producer.php?s=100000 , the data is returned without issue, as you can see in the screenshot above. can you reproduce the issue using my producer.php code?
btw, interestingly, when i try 1 million bytes, i get this error from curl:
$ curl -I http://127.0.0.1/producer.php?s=1000000

Hanshenrik,
i also used CURLOPT_VERBOSE as you said. Here are the 2 curl logs.
The only difference is the line
<* stopped the pause stream!> in the Ubuntu curl log.

How to successfully resend a POST request and get the correct respond without knowing the actual payload

I've been working on to capture a multiple post requests from an android app for testing purpose.
Unfortunately, I'm stuck in finding a way to get the actual payload of the request by using a request sender to resend the request. I could get 200 status code but I could only get a wrong respond, and that is not what I expected. I'm hoping to get any advice in here if it's possible?
The request is sent via a POST method.
The request address looks like this(from my perspective it doesn't have a body, does it?)
http://proxy.ABC.ABC.com/ABC/qryunreadmsgcount.do?d=2&m=1&t=803514
Please correct me if the description or the title needs further editing .
Cheers
=========================================================================
Edit:
this is the respond that I got

POST from REST console perceived as GET by server

Im using both the chrome REST API console and Postman to send a post request to my server (running nginx and symfony2)
Its a very simple request, just simply posting to a URL with an empty body. If this request runs from another server via a HTTP request, it will register as POST. Trying to POST from the api consoles registers as GET in my nginx access logs and returns a 405 Method not allowed.
If I use curl I initially get a 301 Moved Permanently, so I have to use -L to follow redirects. Im not sure if this is standard Symfony or if it is effecting the request.
I've found some problems with the curl request, but am unsure how to resolve them.

If you look closer, you will see your request is with HTTP. Then your server sends a redirect to your HTTPS site. And a 301 redirect does not preserve the request method. You MUST issue all your requests correctly against HTTPS.

Heroku router closing persistent http/1.1 connection requests?

I have a application hosted on Heroku, and it seems to be adding a Connection:close to the response header of a HTTP/1.1 connection request, and not allowing us to re-use a persistent HTTP/1.1 connection. This works for other apps I have on Heroku, but I can't figure out why it would do this for this app. Any clues?
So if I attempt to test with curl for example,
curl -v "http://myapp.herokuapp.com/api/posts/trending" "http://myapp.com/api/posts/trending"
* Connected to myapp.herokuapp.com () port 80 (#0)
> GET /api/posts/trending HTTP/1.1
> User-Agent: curl/7.37.1
> Host: myapp.herokuapp.com
> Accept: */*
>

Answering my own question here, according to Heroku Support, it is known limitation of the Heroku router, since Jetty doesn't send Connection: keep-alive in the response of HTTP/1.1 request by design. No suggested workarounds at this time.

Http protocol content-length

I am working on a simple download application. While making a request for the following file both firefox and my application doesn't get the content-length field. But if i make the request using wget server does send the content-length field. I did change wgets user agent string to test and it still got the content-length field.
Any ideas why this is happening?

Content-Type: video/mp4
Transfer-Encoding: chunked
Update:
Is there a header that I can send that will tell Lighthttpd not to use chunked encoding.My original problem is that I am using urlConnection to grab the file in my java application which automatically sends HTTP 1.1 request.
I would like to know the size of the file so i can update my percentage.
GET
/dc-13/video/2005_Defcon_V2-P_Zimmerman-Unveiling_My_Next_Big_Project.mp4
HTTP/1.1
Firefox is performing an HTTP 1.1 GET request. Lighthttpd understands that the client will support chunked-transfer encoding and returns the content in chunks, with each chunk reporting its own length.
GET
/dc-13/video/2005_Defcon_V2-P_Zimmerman-Unveiling_My_Next_Big_Project.mp4
HTTP/1.0
Wget on the other hand performs an HTTP 1.0 GET request. Lighthttpd, understanding that the client doesn't support HTTP 1.1 (and thus chunked-transfer encoding), returns the content in one single chunk, with the length reported in the response header.
Looks like it's because of the chunked transfer encoding:
Transfer-Encoding: chunked
This will send the video down in chunks, each with its own size. This is defined in HTTP 1.1, which is what Firefox is using, while wget is using HTTP 1.0, which doesn't support chunked transfer encoding, so the server has to send the whole file at once.
I was having the same problem and found a solution regardless of which HTTP version:
First use a HEAD request to the server which correctly responds with just the HTTP header and no contents. This header correctly includes the wanted Content-Length: bytes size for the file to download.
Proceed with the GET request to download the file (the header from the GET response fails to include Content-length).
An Objective-C language example:
NSString *zipURL = #"http://1.bp.blogspot.com/_6-cw84gcURw/TRNb3PDWneI/AAAAAAAAAYM/YFCZP1foTiM/s1600/paragliding1.jpg";
NSURL *url = [NSURL URLWithString:zipURL];
// Configure the HTTP request for HEAD header fetch
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];
urlRequest.HTTPMethod = #"HEAD"; // Default is "GET"
// Define response class
__autoreleasing NSHTTPURLResponse *response;
// Send HEAD request to server
NSData *contentsData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:nil];
// Header response field
NSDictionary *headerDeserialized = response.allHeaderFields;
// The contents length
int contents_length = [(NSString*)headerDeserialized[#"Content-Length"] intValue];
//printf("HEAD Response header: %s\n",headerDeserialized.description.UTF8String);
printf("HEAD:\ncontentsData.length: %d\n",contentsData.length);
printf("contents_length = %d\n\n",contents_length);
urlRequest.HTTPMethod = #"GET";
// Send "GET" to download file
contentsData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:nil];
// Header response field
headerDeserialized = response.allHeaderFields;
// The contents length
contents_length = [(NSString*)headerDeserialized[#"Content-Length"] intValue];
printf("GET Response header: %s\n",headerDeserialized.description.UTF8String);
printf("GET:\ncontentsData.length: %d\n",contentsData.length);
printf("contents_length = %d\n",contents_length);
return;
And the output:
HEAD:
contentsData.length: 0
contents_length = 146216
GET:
contentsData.length: 146216
contents_length = 146216
(Note: This example URL does correctly provides the header Content-Length from the GET response, but shows the idea if it failed to)
