Hello,

#!/usr/local/bin/amm

import $ivy.`com.lihaoyi::requests:0.1.5`

val r = requests.post("http://httpbin.org/post", data = Map("key" -> "value"))

println(r.statusCode)
println(r.headers("content-type"))
println(r.text)

Do you know what's misssing ?

I updated from ammonite 0.7 to ammonite 1.2, it solved the problem

Hello, @lihaoyi thank you for a great project.
Can you tell me why response headers lowercased by default?

Why not leave it as it is?

Does requests-scala support downloading chunked gzip files?

hi there, thumbs up for the great lib.
Are there any plans to support other kind of proxys? Seems like socks5 isn't supported currently

Hi, I think it's not directly related to requests-scala, i did find a simple to do it, let met explain :

I create a session for qualifEnv (let us say baseUrl: https://qualif.gatway): `val qualifEnv = requests.Session(some specific config for qualif)
Now i do a call: qualifEnvSession.get(s"$baseUrl/resource", ...)

It could be cool to have a scoped requests instance allowing: qualifEnvSession.get("resource", ...), which takes care about addding the baseUrl.

I did not find a simple way to do that, if have you ideas, thank you

with geny.Readable and geny.Writable, and a scoped by env requests instance, we could have a less error prone and smooth tool for data migration between envs

do we have support for proxies on this library?

@lihaoyi I have been using the lib for a while now, but i need to go through a proxy. Does the library support proxy as the python one?

Hi
I'm feeling that the way this library is going forces me to use var more than it should.
If reading a stream from GET I have to use a var to store the StreamHeaders value and then only read from the stream if response is SC_OK, like this:

var responseHeaders: Option[StreamHeaders] = None
requests.get.stream("https://some.url", check = false
    , onHeadersReceived = streamHeaders => {
        responseHeaders = Some(streamHeaders)
        if (streamHeaders.statusCode == HttpServletResponse.SC_OK) {
            // stuff
        } else {
            // other stuff
        }
    }).readBytesThrough{ inputStream =>
    if (responseHeaders.exists(_.statusCode == HttpServletResponse.SC_OK)) {
        // read stream
    } else {
        // don't
    }
}

It would be great if one could do this (access streamHeaders in the Readable:

val readable = requests.get.stream("https://some.url", check = false
    , onHeadersReceived = streamHeaders => {
        if (streamHeaders.statusCode == HttpServletResponse.SC_OK) {
            // stuff
        } else {
            // other stuff
        }
    })
if (readable.streamHeaders.statusCode == HttpServletResponse.SC_OK) {
    readable.readBytesThrough{ inputStream =>
        // read stream
    }
}

i've been working with requests-scala in an (sbt 1.3.7/scala 2.13.1) app with utests without any problems, as per:

"com.lihaoyi" %% "requests" % "0.5.0",

however, when i run an ammonite script mimicking the successful utest with ammonite 1.6.3 (scala 2.12.8 on macOS 10.15.3):

import $ivy.`com.lihaoyi::requests:0.5.0`
import $ivy.`com.lihaoyi::pprint:0.5.6`, pprint._

// requires fsm-interface.FsmInterface to be up and running
val host = "http://localhost:8080"
val resp = requests.get(s"$host/echo")
pprintln(resp.statusCode)
pprintln(resp.text())

i get

Compiling /Users/psc/Documents/Development/Scala/fsm/interface/src/main/sc/fsm-interface.sc
fsm-interface.sc:6: Symbol 'type geny.ByteData' is missing from the classpath.
This symbol is required by 'class requests.Response'.
Make sure that type ByteData is in your classpath and check for conflicting dependencies with `-Ylog-classpath`.
A full rebuild may help if 'Response.class' was compiled against an incompatible version of geny.
val resp = requests.get(s"$host/echo")
                    ^

val res_5 = pprintln(resp.text())
                          ^

(the pprint import works fine and can be used.)

@xraybat

problem above goes away using latest ammonite installed via coursier / cs CLI.

might be time to move in a coursier / mill direction and away from sbt...

xraybat

@xraybat

(altho sbt 1.3.x apparently uses coursier out of the box anyway…)

I've been working with requests-scala but when I have a 404 error, I have a exception with Geny, is that normal ?

scala>val r = requests.get("https://www.freebsd.org/fsdkfjsdkfd")
scala> println(r.toString)
<console>:12: error: not found: value r
       println(r.toString)

Magnus Larsson

@Magua

val r = requests.get("https://www.freebsd.org/fsdkfjsdkfd", check = false)

New version of requests will throw exceptions for non 2** http return codes. check = false will give the old behavior.

Hi,
I had problems with delete method. I was able to get success response from Postman and my react project.
I later noticed that the body is not sent. I created a PR lihaoyi/requests-scala#65
This is similar to the PATCH change which was added in January (lihaoyi/requests-scala#47)

I have a Django API based on JWT, from which I have to receive json data. I have been able to get the access token. But, with the following, I am getting the error from the Python server that No Post Data.
val data: Response = requests.post(
"http://....",
data=ujson.Obj("username" -> username).render(),
headers=Map(
"Authorization" -> s"Bearer $accessToken",
"Content-Type" -> "application/json",
)
)

The details "data=ujson.Obj("username" -> username).render()" is supposed to be read in Django API as "request.POST.get('username')"

Any idea as to how to resolve this?

Hello! Any idea if I'm missing an import?
I'm getting this error by just running a command from requests-scala's readme in amm REPL without any additional imports.

@ requests.post("http://localhost:9000", data = ujson.Obj("hello" -> "world"))
cmd1.sc:1: overloaded method value apply with alternatives:
  (r: requests.Request,data: requests.RequestBlob)requests.Response <and>
  (url: String,auth: requests.RequestAuth,params: Iterable[(String, String)],headers: Iterable[(String, String)],data: requests.RequestBlob,readTimeout: Int,connectTimeout: Int,proxy: (String, Int),cookies: Map[String,java.net.HttpCookie],cookieValues: Map[String,String],maxRedirects: Int,verifySslCerts: Boolean,autoDecompress: Boolean,compress: requests.Compress,keepAlive: Boolean)requests.Response

val res1 = requests.post("http://localhost:9000", data = ujson.Obj("hello" -> "world"))
                    ^
Compilation Failed

I tried importing the library explicitly, with similar results
import $ivy.{`com.lihaoyi::requests:0.6.5`, `com.lihaoyi::ujson:0.9.5`}

Anybody know why I'm getting a TimeoutException when running val r = requests.get("https://bad-api-assignment.reaktor.com/v2/availability/okkau/") in Ammonite? In the browser it works fine, I'm not sure why I get a timeout.

Raul Rodriguez

@rarodriguez94

You could include a readTimeout if the server takes time to get back

I am trying to import and use requests in a Databricks notebook.

I am getting this error:

command-1361810570373404:40: error: object post is not a member of package requests
      requests.post(

Also, if I try to import the package with import com.lihaoyi.requests._ I am not finding it:

command-497441197922137:2: error: object lihaoyi is not a member of package com
import com.lihaoyi.requests._

Have downloaded the jar from Maven: https://mvnrepository.com/artifact/com.lihaoyi/requests_2.13/0.5.2
Datbricks runtime 7.5 (includes Apache Spark 3.0.1, Scala 2.12)
Any idea how to properly import and use the library in Databricks?
Cheers.

Hi, can anyone take a look at this issue and maybe give some pointers?
com-lihaoyi/requests-scala#88

Benjamin Kha

@benkha

does requests support a list of query params

similar to Python

>>> payload = {'key1': 'value1', 'key2': ['value2', 'value3']}

>>> r = requests.get('https://httpbin.org/get', params=payload)

Yair Ogen

@yairogen

@benkha yes. https://github.com/com-lihaoyi/requests-scala#passing-in-parameters

Benjamin Kha

@benkha

ah ya thanks, I was talking about the case where you have multiple values for the same value, so passing Map[String, String] wont work

but looks like you can pass in List[(String, String)], just not in the documentation

Hi what is the equivalent in request of this curl post request ?

curl --location --request POST 'https://some.url/foo' \
--form 'title="MY_TITLE"' \
--form 'file=@"/PATH/FILE.mp3"'

If as you can see it is a form post request with both a key value and a file

Given that I send gzip using :

def sendString(txt: String): Unit = {
 requests.post("http://localhost:8000/test",
    compress = requests.Compress.Gzip,
    data = txt)
}

how do I read the stream on the server?

If I send gzip data as an Array[Byte] I can use:
override def handle(t: HttpExchange) {
  val is = new GZIPInputStream(t.getRequestBody)

and just stream into a StringBuilder or something but that doesn't work.
