            cURL command line keep connection open
            Asked 2022-Jan-31 at 12:28

            Is there a way of getting curl (command line tool) to keep a http connection open? I am trying to test/debug a server application, which has a client that opens a http connection, makes a PUT request and leaves it open until some further action, and have been trying to use curl to simulate this.

            However, according to the curl website:

            The curl command-line tool can, however, only keep connections alive for as long as it runs, so as soon as it exits back to your command line it has to close down all currently open connections.

            That much is fine, but is there a way of forcing it not to exit back to the command line (until I press any key or Ctrl-C or whatever it prefers), and therefore hold the connection open while I do the testing?

            I have tried the "Connection: keep-alive" header but this doesn't do the trick, the process still ends as soon as it's made the request, and the connection is closed.

            If not, is there an alternative tool that can do this?

            ...

            ANSWER

            Answered 2022-Jan-31 at 12:28

            You can "trick" curl to keep the connection open. For example like this:

            1. Fire up nc to listen to a local port, say 8080 (nc -l -p 8080 on some versions of nc)
            2. Run curl to get the resource you want, then add "localhost:8080" as a second URL on the same command line

            This will make curl hold the first connection in its pool when it gets the second URL, and you make that second transfer just hang "indefinitely" which will make curl just leave the first connection open and alive until you control-c that or your nc process.

            How to make a request to an IPv6 address using the http-client package in haskell?
            Asked 2022-Jan-28 at 16:01

            I've been trying to make a request to an IPv6 address using the parseRequest function from Network.HTTP.Client (https://hackage.haskell.org/package/http-client-0.7.10/docs/Network-HTTP-Client.html) package as follows:

            request <- parseRequest "http://[2001:0db8:85a3:0000:0000:8a2e:0370:7334]"

            Instead of parsing it as an address/addrInfo, it is parsed as a hostname and throws the error: does not exist (Name or service not known). As a next step, I tried pointing a domain to the same IPv6 address and then using the domain name in parseRequest, then it successfully resolves that into the IPv6 address and makes the request. Is there some other way I can directly use the IPv6 address to make the request using the http-client package?

            PS: I also tried without square brackets around the IP address, in this case the error is Invalid URL:

            request <- parseRequest "http://2001:0db8:85a3:0000:0000:8a2e:0370:7334"

            More context:

            For an IPv4 address, the getAddrInfo function generates the address as:

            AddrInfo {addrFlags = [AI_NUMERICHOST], addrFamily = AF_INET, addrSocketType = Stream, addrProtocol = 6, addrAddress = 139.59.90.1:80, addrCanonName = Nothing}

            whereas for IPv6 address(inside the square brackets format):

            AddrInfo {addrFlags = [AI_ADDRCONFIG], addrFamily = AF_UNSPEC, addrSocketType = Stream, addrProtocol = 6, addrAddress = 0.0.0.0:0, addrCanonName = Nothing}

            and the error prints as:

            (ConnectionFailure Network.Socket.getAddrInfo (called with preferred socket type/protocol: AddrInfo {addrFlags = [AI_ADDRCONFIG], addrFamily = AF_UNSPEC, addrSocketType = Stream, addrProtocol = 6, addrAddress = 0.0.0.0:0, addrCanonName = Nothing}, host name: Just "[2001:0db8:85a3:0000:0000:8a2e:0370:7334]", service name: Just "80"): does not exist (Name or service not known))

            Answered 2022-Jan-28 at 16:01

            When a literal IPv6 address is used in a URL, it should be surrounded by square brackets (as per RFC 2732) so the colons in the literal address aren't misinterpreted as some kind of port designation.

            When a literal IPv6 address is resolved using the C library function getaddrinfo (or the equivalent Haskell function getAddrInfo), these functions are not required to handle these extra square brackets, and at least on Linux they don't.

            Therefore, it's the responsibility of the HTTP client library to remove the square brackets from the hostname extracted from the URL before resolving the literal IPv6 address using getaddrinfo, and the http-client package doesn't do this, at least as of version 0.7.10. So, this is a bug, and I can see you've appropriately filed a bug report.

            Unfortunately, I don't see an easy way to work around the issue. You can manipulate the Request after parsing to remove the square brackets from the host field, like so:

            Is it necessary to encrypt the payload before sending out the post request?
            Asked 2022-Jan-19 at 03:56

            I'm using angular as my frontend to do a login panel and send a post request to the backend which is a express API. My domain has a SSL already, so the safety between the transfer should be good.

            But I'm wondering when I open the devtool and check the request payload, the plaintext of the loginname and password is show up.

            Do I need to encrypt the payload before sending post request to make it invisible? If needed, what library I can use for this?

            ANSWER

            Answered 2022-Jan-19 at 03:39

            No you do not need to encrypt the payload. SSL will do that for you. The payload would be secure between the client and the server.

            Devtools can be only opened on the local instance of chrome client. Dev Tools only starts capturing data when it is open and if a request is made. Cannot be used in man-in-the-middle attack.

            Tell me please, what is the main difference between options CURLOPT_MIMEPOST and CURLOPT_POSTFIELDS ?

            ANSWER

            Answered 2021-Dec-08 at 09:19
            CURLOPT_POSTFIELDS

            Sends exactly the bytes you specify in the body of the HTTP request. With a default Content-type of application/x-www-form-urlencoded. libcurl will not add or encode the data in any way for you.

            With the curl command line tool, you do this with -d.

            CURLOPT_MIMEPOST

            Makes libcurl send a "multipart formpost". That is a data stream using a format that allows the sender to send multiple "parts" of data to the server, each part being properly separated and identified. Each part has a name, content and its own set of headers. When an HTTP client "uploads a file", this is almost always done using multipart formposts.

            Multipart formpost is structured data in the request body and this option helps you produce and send that format. An application can also produce that format by themselves should they prefer that and provide it with CURLOPT_POSTFIELDS or even using the callback CURLOPT_READFUNCTION.

            With the curl command line tool, you do this with -F.

            I've been working on something similar recently and would suggest you try using the kovan network and the oracle that chainlink has there. Even more specifically, I think it would be a good idea to confirm you can get it working using the api, oracle, and jobid listed in the example on that page you are following... here:

            https://docs.chain.link/docs/advanced-tutorial/#contract-example

            Once you get that example working, then you can modify it for your usage. The jobid in that tutorial is for returning a (multiplied) uint256... which, for your API, I think is not what you want as you are wanting bytes32 it sounds like... so when you try to use it with your API that returns bytes32 the jobid would be: 7401f318127148a894c00c292e486ffd as seen here:

            https://docs.chain.link/docs/decentralized-oracles-ethereum-mainnet/

            Another thing that might be your issue, is your api. You say you control what it returns... I think it might have to return a response in bytes format, like Patrick says in his response (and his comments on his response) here:

            Get a string from any API using Chainlink Large Response Example

            Hope this is helpful. If you cannot get the example in the chainlink docs to work, let me know.

            Asked 2021-Dec-19 at 11:53

            Hy there everyone, I'm new to Flutter and I'm want to show RTSP stream from my IP Camera. Is there any way to play RTSP streams in Flutter WEB.

            ...

            ANSWER

            Answered 2021-Dec-16 at 16:45

            Near as I can tell, there's no video player (for web) that supports RTSP or even HLS right now. Even the official video_player package from the flutter dev team doesn't seem to support that on web, yet. I can offer a workaround though....

            If you implement a decent webrtc package and a media server, you can bypass the need to receive RTSP directly on your client. I've been using the flutter_webrtc package for a while now via the livekit_client package. Livekit has a SFU that could be used to proxy RTSP streams for communication to WebRTC enabled clients. I've seen a lot of people use ant media server for that sort of thing as well, and I'm pretty sure you can use the community edition of Ant for free.

            People tend to use media servers for aggregating video streams so that instead of 1 client subscribing to 15 streams from various sources, instead a media server somewhere with a very good Internet connection and decent hardware subscribes to those streams and then generates a new video stream (or streams) such that your phone, or tablet, or laptop client somewhere on a 4G network, only has to receive (a) WebRTC stream(s) that can be optimized on the server in various ways.

            EDIT: I had another thought, I don't know if this would work very well, but you could dynamically generate an HTML page inside an IFrame and use HTMLElementView. This would let you use a JavaScript/HTML5 video player to play your RTSP stream, however it comes with a heavy cost and you'd want to do a platform check to make sure you're running on web before using it.

            How do dynamic API calls work in Nuxt.js static vs SSR mode?
            Asked 2021-Nov-21 at 12:11

            Even after reading through multiple articles explaining the differences between static and SSR rendering I still don't understand how dynamic API calls work in these different modes.

            I know that Nuxt has the fetch and asyncData hooks which are only called once during static generation, but what if I use dynamic HTTP requests inside component methods (e.g. when submitting a form via a POST request)? Does that even work in static sites?

            I'm making a site that shows user generated content on most pages, so I have to make GET requests everytime one of those pages is visited to keep the content up to date. Can I do that with a static site or do I have to use SSR / something else? I don't want to use client side rendering (SPA mode) because it's slow and bad for SEO. So what is my best option?

            ...

            Answered 2021-Nov-21 at 12:11

            I use dynamic HTTP requests inside component methods (e.g. when submitting a form via a POST request)? Does that even work in static sites?

            The short answer to this question is that yes, it does work. In fact you can have http requests in any life cycle hooks or methods in your code, and they all work fine with static mode too.

            Static site generation and ssr mode in Nuxt.js are tools to help you with SEO issues and I will explain the difference with an example.

            Imagine you have a blog post page at a url like coolsite.com/blogs with some posts that are coming from a database.

            SPA

            In this mode, when a user visits the said URL server basically responds with a .js file, then in the client this .js file will be rendered. A Vue instance gets created and when the app reaches the code for the get posts request for example in the created hook, it makes an API call, gets the result and renders the posts to the DOM.

            This is not cool for SEO since at the first app load there isn't any content and all search engine web crawlers are better at understanding content as html rather than js.

            SSR

            In this mode if you use the asyncData hook, when the user requests for the said URL, the server runs the code in the asyncData hook in which you should have your API call for the blog posts. It gets the result, renders it as an html page and sends that back to the user with the content already inside it (the Vue instance still gets created in the client). There is no need for any further request from client to server. Of course you still can have api calls in other methods or hooks.

            The drawback here is that you need a certain way for deployment for this to work since the code must run on the server. For example you need node.js web hosting to run your app on the server.

            STATIC

            This mode is actually a compromise between the last two. It means you can have static web hosting but still make your app better for SEO.

            The way it works is simple. You use asyncData again but here, when you are generating your app in your local machine it runs the code inside asyncData, gets the posts, and then renders the proper html for each of your app routes. So when you deploy and the user requests that URL, she/he will get a rendered page just like the one in SSR mode.

            But the drawback here is that if you add a post to your database, you need to generate your app in your local machine, and update the required file(s) on your server with newly generated files in order for the user to get the latest content.

            Apart from this, any other API call will work just fine since the code required for this is already shipped to the client.

            Side note: I used asyncData in my example since this is the hook you should use in page level but fetch is also a Nuxt.js hook that works more or less the same for the component level.
