If it has, how do we use it?
Hi @mamantoha I want to design a logo for crest. If there is your an idea, please tell me.
Feature request: When doing something like this:
Crest.get("http://example.com") do |resp|
resp.body_io
end
Would it be possible to have the method return the expression from the block? break
/next
don't seem to be respected here, and after looking at the source I think it's because this version of the method always just returns nil?
Or am I missing something?
On Crystal 1.7.0, crest 1.3.7:
require "crest"
r = Crest::Resource.new(
"http://httpbin.org",
headers: { "Foo" => "bar" },
)
response = r.get("/get")
p response.headers
Output:
{"Foo" => "bar", "Date" => "Fri, 13 Jan 2023 23:37:49 GMT", "Content-Type" => "application/json", "Content-Length" => "330", "Connection" => "keep-alive", "Server" => "gunicorn/19.9.0", "Access-Control-Allow-Origin" => "*", "Access-Control-Allow-Credentials" => "true"}

Got below error when try to upload a file without extension.

I think it's reasonable to set a default mime type application/octet-stream
when you can not get it from file extension.
Also, it would be nice to be able to upload IO::Memory
instead of only File
which is possible because HTTP::FormData::Builder#file accepts any instance of IO
.
Crest.get(url, max_redirects: 0, handle_errors: false) do |response|
end
against a response of 302 will always raise a "Found" exception. The usecase is to have a streaming response, but with an ability to detect it in case the site returns a 302 with an invalid response.
Hello,
I have a request I am trying to send with the library. The request takes as a body a JSON that can have an array object as follows:
{:name => name, :options => options, :users => [{:u => 1}]
The library keeps throwing the following error:
no overload matches 'Array(Tuple(String, Bool | Float32 | Float64 | IO | Int32 | Int64 | String | Symbol | Nil))#<<' with type Tuple(String, Array(Tuple(String, Int32)))
Technical information:
Thanks in advance
It would be nice, for my use case at least, if crest had the ability to maintain a pool of internal clients, and gave the user the ability to decide how large that pool was. Something like ysbaddaden/pool could be used underneath.
Hello there here is the following issue I get when trying to run my specs:
In lib/crest/src/crest/logger.cr:1:1
1 | require "log"
^
Error: can't find file 'log'
Currently, below code raises exception:
Crest.post(
"http://httpbin.org/post",
File.open("avatar.png"),
headers: {"Content-Type" => "image/png"}
)
Exception:
In src/crest/request.cr:125:7
125 | generate_form_data!(form) if form
^------------------
Error: no overload matches 'Crest::Request#generate_form_data!' with type File
Overloads are:
- Crest::Request#generate_form_data!(form : Hash)
- Crest::Request#generate_form_data!(form : String)
It seems to be trivial to support it, see code in https://github.com/cyangle/crest/tree/support_io_as_form_data
trying to connect to an https url with:
Crest.get("https://url", read_timeout: 5.second)
but getting this error:
Unhandled exception: SSL_connect: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed (OpenSSL::SSL::Error)
Is there a way to ignore the cert like in Curl with -k or something?
i checked logger.cr and common_logger.cr both are 100% copy my halite code, why do that?
Hey! ๐
Thanks for this great shard! I'm currently using it to consume an API that requires a JSON schema, that contains arrays and numbers. If I understand correctly one can use params that are converted to JSON automatically. However params have the type Hash(String, String) so we cannot use different types for values.
According to the documentation there is the possibility to pass a raw string as a second argument to Crest.post
. However, this throws a compiler error for me:
Error: no overload matches 'Crest.post' with types String, String
Was this behavior changed recently and is there an alternative to use?
This code cause an error:
Crest.post("http://localhost/add-files", payload: {"files[file.txt]" => file, "type" => "txt"})
Crest.post("http://localhost/delete-file", payload: {"file" => "file.txt"})
in /usr/lib/crystal/primitives.cr:175: type must be Array(File | String), not (Array(File | String) | Array(String))
@mamantoha Could you publish a new release with the latest changes? Thanks.
The application that I'm working on submits an authentication request and receives a token and then uses that token to submit a request for data. Sometimes, the auth succeeds but the main request times out. I want to trigger a repeat of the main request at that point.
I can catch the error and repeat the request, but that seems to cause an issue with the subsequent processes. Is there a recommended way to repeat on failure?
Thanks!
Marc
Response with 404 code should raise Crest::NotFound
etc
When attempting to contact a JSON API over HTTPS I get an OpenSSL Error. I'm able to access the website in Safari without an issue so I know it's not a server issue. Could the developers please advise on this?

The documentation says that this code should be correct:
Crest::Utils.flatten_params({:key1 => {:arr => ["1", "2", "3"]}, :key2 => "123"})
# => {"key1[arr][]" => "1", "key1[arr][]" => "2", "key1[arr][]" => "3", "key2" => "123"}
Actual result is {"key1[arr][]" => "3", "key2" => "123"}
Extract the query parameters and append them to the url
response = Crest.post(url, {
"name" => "hello",
"time" => Time.utc.to_unix
}, json: true)
The code above will not compile with the following message
Showing last frame. Use --error-trace for full trace.

Error: no overload matches 'Array(Tuple(String, Bool | File | Int32 | String | Symbol | Nil))#<<' with type Tuple(String, Int32 | Int64 | String)
Overloads are:
- Array(T)#<<(value : T)
Integer values in Crystal JSON are Int64. Currently, I worked around this issue by editing Crest's source to include Int64 in the ParamsValue
type.
alias ParamsValue = Bool | Int32 | String | Symbol | Nil | File? | Int64 <--- this one
Hi, I looked around inside the source but I didn't find an obvious way to achieve the same result of this code:
require "http/client"
HTTP::Client.get("http://example.org") do |response|
File.write("example.com.html", response.body_io)
end
I think that It may be an interesting feature to develop and one little feature that could make Crest even more awesome.
For any kind of info about the context in which I would personally love to have this feature don't hesitate to ask me, I'll be more than happy to talk about it!
Cheers! ๐ป
