有一些使用Phoenix製作的API,API使用JSON。如何爲Phoenix Request強制執行JSON編碼?
但是,當您測試它並向curl
發送JSON時,它會失敗,因爲Phoenix不會將請求解析爲JSON。您需要明確添加application/json
表頭到curl
。我想讓它更加強大,並告訴Phoenix始終將所有請求解析爲JSON。
有沒有辦法強制Phoenix將請求視爲JSON並將其解析爲JSON?
UPDATE
我試圖用插頭設置請求頭作爲@AbM建議的,在路由器以下代碼:
def set_format conn, format do Plug.Conn.put_private conn, :phoenix_format, format end
def put_req_header conn, {key, value} do Plug.Conn.put_req_header conn, key, value end
pipeline :api do
plug :put_req_header, {"accept", "application/json"}
plug :put_req_header, {"content-type", "application/json"}
plug :set_format, "json"
plug :accepts, ["json"]
end
請求已經由具有CURL
curl -X POST http://localhost:4000/api/upload -d '{"key": "value"}'
連接看起來像:
%Plug.Conn{adapter: {Plug.Adapters.Cowboy.Conn, :...}, assigns: %{},
before_send: [#Function<1.93474994/1 in Plug.Logger.call/2>,
#Function<0.119481890/1 in Phoenix.LiveReloader.before_send_inject_reloader/1>],
body_params: %{"{\"key\": \"value\"}" => nil},
cookies: %Plug.Conn.Unfetched{aspect: :cookies}, halted: false,
host: "localhost", method: "POST", owner: #PID<0.483.0>,
params: %{"{\"key\": \"value\"}" => nil},
path_info: ["api", "upload"], peer: {{127, 0, 0, 1}, 58408},
port: 4000,
private: %{App.Router => {[], %{}},
:phoenix_action => :upload,
:phoenix_controller => ApiController, :phoenix_endpoint => App.Endpoint,
:phoenix_format => "json", :phoenix_layout => {LayoutView, :app},
:phoenix_pipelines => [:api],
:phoenix_route => #Function<8.59735990/1 in App.Router.match_route/4>,
:phoenix_router => App.Router, :phoenix_view => ApiView,
:plug_session_fetch => #Function<1.89562996/1 in Plug.Session.fetch_session/1>},
query_params: %{},
query_string: "", remote_ip: {127, 0, 0, 1},
req_cookies: %Plug.Conn.Unfetched{aspect: :cookies},
req_headers: [{"user-agent", "curl/7.37.1"}, {"host", "localhost:4000"},
{"accept", "application/json"}, {"content-length", "16"},
{"content-type", "application/json"}],
request_path: "/api/upload", resp_body: nil, resp_cookies: %{},
resp_headers: [{"cache-control", "max-age=0, private, must-revalidate"},
{"x-request-id", "xxx"}], scheme: :http,
script_name: [],
secret_key_base: "xxx",
state: :unset, status: nil}
它的作品,如果我將-H "Content-Type: application/json"
參數添加到CURL,沒有它不起作用。
會在['put_req_header(conn,「accept」,「application/json」)添加一個插件到你的路由器中, ](https://hexdocs.pm/plug/Plug.Conn.html#put_req_header/3)解決你的問題? – AbM
不是,它不工作:( –
你可以詳細說明一下,也許顯示你的router.ex – AbM
