I know there are lot of questions similar to this, but no one helped me.
I have to make a C program, using socket and no external lib, that sends an HTTP POST request to a web server and manage its JSON answer.
The URL is like this:
meswebapptest.hermanmiller.com/mes/rest/r2Label/print/userId/company/unitId/prodOrder/printer
i.e.
meswebapptest.hermanmiller.com/mes/rest/r2Label/print/Biesse/105/1B6D0X-----11225105/112251/Q0161B8
So my question is: How the string should be formatted to match that URL?
Thanks in advice.

I am new to working with API and was given an assignment to get response data from the API in ReactJS.
The API given to me is this:
To get the response from it I have tried this method and I'm not able to get the response from the API after posting data.
I think I might have been doing the mistake with sending the request using the inputs.
Is anyone aware of what exactly my mistake in getting the response from API and guide me solve this issue I'm facing with it.
Whatever ideas you feel that can be of help to me feel free to assist me. I'll give my sandbox link to further code reference of what I have done and ask me if anything you need regarding the code.

I think the mistake I have done is when I'm sending the post request to the API with the input parameters.
While integrating FreshDesk in my product,I am stuck with Create Ticket with attachment API. I am using Advanced Rest Client for testing APIs.I have seen many forums and questions on the Stack Overflow itself but I am still not satisfied with any answer pertaining to multipart-form-data POST request for uploading files.
I would like to know the Request Format required in Advanced Rest Client along with headers.
As of now, this is the request I am using but I am not getting a proper response:
-----------------------------7d01ecf406a6
Content-Disposition: form-data;name="files";filename="text1.txt"
Content-Type:text/plain
Its a nice day.
-----------------------------7d01ecf406a6--
I just spent the last hour on this same issue, thinking I was doing something wrong. I eventually gave up on ARC and tried PostMan and set all the values the same and it worked on the server-side (I'm using node.js+hapi) where previously the server was returning 415 with little more info (there's an open issue in Hapi regarding this).
After seeing the requests at the server when using PostMan and considering the UI feedback ARC regarding multi-part (implying it would overwrite any included content-type headers), I've concluded that it's supposed to overwrite/include the content-type header AND provided the boundary, but is not and so my requests were failing.
I've also looked at closed and open issues for ARC ( https://github.com/jarrodek/ChromeRestClient/issues?utf8=%E2%9C%93&q=is%3Aissue%20multipart ) and it looks a lot like there are known issues with multi-part uploads from the client so I'd suggest you not spend too much more time with ARC until you've tried another client to eliminate ARC as the source of your issues.
You need to set proper Content-Type header
Content-Type: multipart/form-data; boundary=---------------------------7d01ecf406a6
Server needs to know what to look for in the request body. In case of multipart/form-data you need to pass the boundary you have used in the Content-Type header.
I am trying to develop a website that reads a JSON response from a certain endpoint and post it after certain processing to the page.
I am using $http.get(url) (AngularJS)
However I am facing problems getting the response.
I have tried to use other URLs and it worked then the cause of the problem probably is not the code.
The Error is: "No Access Control Allow Origin header is present on the requested resource".
Other responses suggested something related to CORS and privacy issues ; but when i type the URL directly in my browser it gives a JSON response directly. (So basically there is no privacy issues in the server side right?)
My question is what should I do ? Is there another way to get the content of the page pointed by the url (i am sure that it will only contains the JSON response)
Thanks in Advance
I came across this question:
1. If we substitute the URL in the address bar, it is similar to receiving data from the server of this site
In order to send requests to other servers need to use JSONP HTTPS for secure channel
Sending data can be carried out, but with the replies received will be a problem in the form JSON
Please send to the server if use PHP, then use CURL
JS->Our server->Server api->Our server->JS
My issue is simple: I want to make an HTTP GET request from a server. My client program takes a URL and sends it to the server program. I want to know how I can take this URL and make an HTTP GET request for the specific page that was entered from the client.
If I resolve the URL to get an IP address, I could open a socket to that IP address, but then how would I make the request for the actual page? Would I just send an HTTP GET request directly to that IP address with the directory in the request?
For instance, if I ran a Google search for the word "Test" I'd be presented with the following URL:
https://www.google.com/?gws_rd=ssl#q=Test
My understanding is that a GET request could look like this:
GET /?gws_rd=ssl#q=Test HTTP/1.1
Host: www.google.com
So, if I'm understanding this correctly, would I resolve the IP, open a socket, and then just send this GET request directly to the socket?
Lastly, if I try throwing a URL such as the one above into my server code it's unable to resolve an IP address. This means that if I'm making a more complex request than something like www.google.com I'd have to parse the string and match only the host. Is there a simple way to handle this other than by the use of regular expressions? I'm familiar with regular expressions from Python and C#, but if I can cut down on the complexity of the program by approaching this differently, I'd like to know.
Update: I'm attempting to match the URL with a POSIX regular expression and extract the domain name from it. I'm not having much luck so far as this implementation is oppressively confusing.
Yes, once a socket has been opened you could send requests as in your example and described in RFC 2616.
If you don't want to use regular expressions or strchr to split your URL you cold also send the entire URL:
`GET http://www.google.com/?gws_rd=ssl#q=Test HTTP/1.1
`
However, you will still need to find the hostname in the URL to make a call to something like gethostbyname.
I'm working on a C coded server that have to reply to browsers' requests. It have to give authentication when using url like this:
http://user:pass#website/
but I really don't know how or where get this information on my server, because what I got when I read the request is the same that I can read when I interact with the server simply using
http://website/
Second question is that sometime I have this favicon.ico request from browsers.. what can I reply to the browser to say "I have not this fu*** stupid icon"? :D
I'm of course using socket for this
Look for a request header named Authorization: containing the string Basic followed by the BASE64 encoded username and password. This method of authenticating is called HTTP Basic Authentication.
For the favicon, simply respond with a HTTP 404 response if you don't have one.
