我mix fetch.btc在 phoenix 应用程序上有混合任务（lib/mix/tasks/fetch.btc.ex）：
defmodule Mix.Tasks.Fetch.Btc do
use Mix.Task
def run(_args) do
res = HTTPoison.get!("https://blockchain.info/ticker")
IO.inspect(res)
end
end
当我运行时mix fetch.btc出现错误：
** (ArgumentError) argument error

尝试使用 HTTPoison 将图像发布到 Spree 的ProductImage API时，失败并出现 Rails 错误NoMethodError (undefined method 'permit' for #<ActionDispatch::Http::UploadedFile:0x007f94fa150040>)。我用来生成此请求的 Elixir 代码是：
def create() do
data = [
{:file, "42757187_001_b4.jpeg",
{"form-data", [{"name", "image[attachment]"}, {"filename", "42757187_001_b4.jpeg"}]},
[{"Content-Type", "image/jpeg"}]
}, {"type", "image/jpeg"}
]
HTTPoison.post!("http://localhost:3000/api/v1/products/1/images", {:multipart, data}, ["X-Spree-Token": "5d096ecb51c2a8357ed078ef2f6f7836b0148dbcc536dbfc", "Accept": "*/*"])
end
我可以通过以下调用使用 Curl 使其工作：
curl -i -X POST \
-H "X-Spree-Token: 5d096ecb51c2a8357ed078ef2f6f7836b0148dbcc536dbfc" \
-H "Content-Type: multipart/form-data" \
-F "image[attachment]=@42757187_001_b4.jpeg" \
-F "type=image/jpeg" \
http://localhost:3000/api/v1/products/1/images
为了进行比较，下面是失败的 HTTPoison 请求和成功的 Curl 请求的 RequestBin 捕获： https://requestb.in/12et7bp1?inspect

我正在尝试使用 tesla 发出帖子请求，但出现错误：

我的请求代码是
request_body = %{
name: "ecdebit",
}
Tesla.post(client, "/contactdb/lists", request_body)
在特斯拉基本网址是：https://api.sendgrid.com/v3并设置授权key。我们如何为 post 请求传递数据？
在特斯拉文档中，将发布请求定义为：
Tesla.post("http://httpbin.org/post", "data", headers: [{"content-type", "application/json"}])
这个星球上有没有人可以帮助摆脱这个小故障:(。
在我的Phoenix应用程序中，我试图使用HTTPoison HTTP客户端（https://hexdocs.pm/httpoison/api-reference.html）向AgileCRM API发出发布请求。我能够使用cURL发出成功的请求，但是我尝试在Phoenix中复制它的尝试失败，出现401 UNAUTHORIZED错误。
我成功的cURL：
$ curl https://domain.agilecrm.com/dev/api/contacts/search/email \
-H "Accept: application/json" \
-d 'email_ids=["contact@test.com"]' \
-u admin@test.com:api_key
返回状态200和请求的数据。
我失败的HTTPoison：
url = "https://domain.agilecrm.com/dev/api/contacts/search/email"
body = Poison.encode!(%{"body": "email_ids=['contact@test.com']"})
headers = [{"Accept", "application/json"}, {"Authorization", "admin@test.com:api_key"}]
response = HTTPoison.post!(url, body, headers)
IO.inspect response
哪个返回
