设置cookies正确

这是很简单的使用erlang:display(Req)使用这种方法设置cookies正确

init(Req0, Opts) ->  
    Method = cowboy_req:method(Req0), 
    {ok, Body0, _} = cowboy_req:read_urlencoded_body(Req0), 
    {ok, RiakPid} = riakc_pb_socket:start("127.0.0.1", 8087), 
    Req = handle(Method, Body0, Req0, RiakPid),  
    {ok, Body, _} = cowboy_req:read_body(Req), 
    erlang:display(Req), % here I also check request  
    {ok,Req, Opts}. 

% post 
handle(<<"POST">>, Body, Req0, RiakPid) -> 
    SessionID = "blablabla", 
    Req = cowboy_req:set_resp_cookie(<<"token">>, SessionID, Req0), 
    erlang:display(Req) %here I check request 
    Req; 

% get. Here I should successfully get token in cookies 
handle(<<"GET">>, Body, Req0, RiakPid) -> 
    Cookies = cowboy_req:parse_cookies(Req0), 
    {_, Token} = lists:keyfind(<<"token">>, 1, Cookies), % here is when i fail to get cookie by key  
    erlang:display(Token), 
    Req0;

牛仔设置Cookie https://ninenines.eu/docs/en/cowboy/2.0/guide/cookies/

但是当我设置cookie和GET请求：

headers=>#{ 
<<"accept">>=><<"*/*">> 
<<"accept-encoding">>=><<"gzip, deflate, br">> 
<<"accept-language">>=><<"en-GB,en-US;q=0.8,en;q=0.6">> 
<<"connection">>=><<"keep-alive">> 
<<"content-length">>=><<"24">> 
<<"content-type">>=><<"application/x-www-form-urlencoded">> 
<<"cookie">>=><<"user=\"2|1:0|10:1487346656|4:user|4:Mw==|ba24da6f51c92ad05e278f218d15d2cda8ed9e7e3b800dcf39a244de5ecfff37\"">> 
<<"host">>=><<"localhost:2939">> 
<<"origin">>=><<"chrome-extension://eelcnbccaccipfolokglfhhmapdchbfg">> 
<<"user-agent">>=><<"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36">>} 
host=><<"localhost">> 
host_info=>undefined,method=><<"POST">> 
path=><<"/login">> 
path_info=>undefined 
peer=>{{127,0,0,1},53362} 
pid=><0.4104.0>,port=>2939,qs=><<>> 
ref=>my_http_listener 
resp_cookies=>#{<<"token">>=>[<<"token">>,<<"=">>,"blablabla",<<"; Version=1">>,<<>>,<<>>,<<>>,<<>>,<<>>]} 
scheme=><<"http">>,streamid=>1,version=>'HTTP/1.1'}

所以我是设置标题，而不是Cookie。

如何设置真正的饼干？

是水木清华像

<<"cookie">>=> 
<<"user=\"2|1:0|10:1487346656|4:user|4:Mw==|ba24da6f51c92ad05e278f218d15d2cda8ed9e7e3b800dcf39a244de5ecfff37\"">> 
<<"token=\"blablabla\"">>

不行'resp_cookies =>＃{<<"token">> => [<<"token">>，<<"=">>， “blablabla” << “;版本= 1” >>，<<>>，<<>> ，<<>>，<<>>，<<>>]}'在你的'erlang：display（Req）'中表明你正在设置那个cookie？ –

据我了解我的设置标题。而且当我做'cowboy_req：parse_cookies（Req）'我只得到'<< user = \“2 | 1：0 | 10：1487346656 | 4：user | 4：Mw == | ba24da6f51c92ad05e278f218d15d2cda8ed9e7e3b800dcf39a244de5ecfff37 \”“>> ' – Marat

我们可以有一个完整的示例代码，您可以在其中设置Cookie并尝试检索它？ –

下面是正确的代码

% post 
handle(<<"POST">>, Body, Req0, RiakPid) -> 
    SessionID = "blablabla", 
    Req1 = cowboy_req:set_resp_cookie(<<"token">>, SessionID, Req0), 
    erlang:display(Req1) %here I check request 
    Req = cowboy_req:reply(200, Req1), % We should always pass correct Request 
    Req;

请告诉我的观点是：当一个人与申请工作，他也应缴纳的请求和它的地位的关注。当你结束请求（Req = cowboy_req：reply（200，Req1））你的resp_cookies记录传递给cookies。否则，该请求是不完整的
