I'm trying the Reverse routing sample code
Here are my routes
GET /hello/:name controllers.Application.hello(name)
GET /bob controllers.Application.helloBob
and my codes
def helloBob = Action {
Redirect(routes.Application.hello("Bob"))
}
def hello(name: String) = Action {
Ok("Hello " + name + "!")
}
I can get hello response
$ curl -v localhost:9001/hello/play
Hello play!
But, can't get "Bob" response after redirect?
$ curl -v localhost:9001/bob
* Trying ::1...
* Connected to localhost (::1) port 9001 (#0)
> GET /bob HTTP/1.1
> Host: localhost:9001
> User-Agent: curl/7.43.0
> Accept: */*
>
< HTTP/1.1 303 See Other
< Location: /hello/Bob
< Date: Fri, 18 Sep 2015 03:19:04 GMT
< Content-Length: 0
<
* Connection #0 to host localhost left intact
The path component of a URI is case sensitive. Check it.
try
curl -v localhost:9001/hello/Bob
Update
You code is correct (verified on my project) and you show the correct log - it prints 303 code. I think, you just need to say curl to follow redirect, like this
curl -L localhost:9000/bob

Issue
It appears that the request you make incorrectly tries to re-direct to an https protocol (port 443)
Solution
Use https instead of http
curl -s https://localhost:8003/seldon/john/sklearn-iris-deployment-sklearn-iris-predictor-0e43a2c/api/v0.1/predictions -H "Content-Type: application/json" -d '{"data":{"ndarray":[[5.964,4.006,2.081,1.031]]}}' -v
Use curl with -L flag, which instructs curl to follow redirects. In this case, the server returned a redirect response (301 Moved Permanently) for the HTTP request to http://localhost:8003. The redirect response instructs the client to send an additional request, this time using HTTPS, to https://localhost:8003.
More about it here.
Hi I have a requirement to use play framework 2.5 (scala) to receive a large request body, then transform it and then stream it straight back out.
So far I've been unable to get the request stream to be sent out correctly using a chunked response (even untransformed).
Code example:
def endpointA = EssentialAction { requestHeader =>
Accumulator.source.map { source: Source[ByteString, _] =>
Ok.chunked(source)
}
}
POSTing data to the endpoint with curl does not output the posted data as expected and just results in the error below. I confirmed with wireshark that no response body is sent.
curl -v --data 'hello' -H "Connection: Keep-Alive" -H "Keep-Alive: 300" -H "Content-type: text/plain" http://localhost:9584/binding-tariff-admin/upload-csv

curl: (18) transfer closed with outstanding read data remaining
Also, if I change the code to return a stream I create myself, it works fine:
val testStream: Source[ByteString, NotUsed] = Source(List("hello")).map(ByteString.apply)
Is there something fundamentally wrong with what I'm trying to do here? I have seen other stack overflow examples with people suggesting this should be possible, e.g.
Play Framework Scala: How to Stream Request Body
I also tried using the verbatimBodyParser method described in the link but got the same results.
Thanks!

I am trying to develop a rest api for my service wherein I set custom http status code depending on authorisation failure. But when I test it out using curl I am receiving 404 instead of 403. I am perplexed as to what might be causing this? Please help.
This is what I see from curl output or swagger UI:
root#ubuntu:~# curl -X GET http://localhost:8082/mr/v1/topic/bhakk -v
Note: Unnecessary use of -X or --request, GET is already inferred.

I'm just getting started with nginx and the HttpLuaModule. I've created a test configuration file to familiarize myself with how things work.
now I'm trying to write some logic to accept GET, POST and DELETE requests for a specific type of resource.
I would like to create a "location" entry that would match the following URI / accept the following curl calls:
curl -i -X GET http://localhost/widgets/widget?name=testname&loc=20000 -H "Accept:application/json"
This is what my current nginx.conf looks like:
server {
listen 80;
server_name nsps2;
root /var/www/;
index index.html index.htm;
#charset koi8-r;
#access_log logs/host.access.log main;
#curl http://localhost/hello?name=johndoe
location /hello {
default_type "text/plain";
content_by_lua '
local rquri = ngx.var.request_uri;
ngx.say("the uri is ", rquri ,".")
local name = ngx.var.arg_name or "Anonymous"
ngx.say("Hello, ", name, "!")
';
}
location / {
root /var/www/;
index index.html index.htm;
}
#curl -i -X GET http://localhost/widgets/widget?name=testname&loc=20000 -H "Accept:application/json"
location /widgets/widget {
root /var/www/widgets;
default_type "text/pain";
content_by_lua '
local arga,argb = ngx.arg[1], ngx.arg[2] ;
ngx.say("the arga is ", arga ,".")
ngx.say("the argb is ", argb, ".")
';
}
Using the last "location" entry, I'm trying to
1. prove that the system is getting the GET request
2. prove that I understand how to access the parameters passed in with the GET request.
I'm getting an error right now that looks like this:
2015/02/24 20:18:19 [error] 2354#0: *1 lua entry thread aborted: runtime error: content_by_lua:2: API disabled in the context of content_by_lua*
stack traceback:
coroutine 0:
[C]: in function '__index'
content_by_lua:2: in function <content_by_lua:1>, client: 127.0.0.1, server: nsps2, request: "GET /widgets/widget?name=testname?loc=20000 HTTP/1.1", host: "localhost"
I'm not too sure about what this error means / is trying to tell me.
Any tips would be appreciated.
Thank you.
EDIT 1
I think the problem was something syntactically wrong. I was reading the manual and found an example to try. I've changed the code to look like this:
location /widgets/widget {
default_type "text/pain";
content_by_lua '
local args = ngx.req.get_uri_args()
for key, val in pairs(args) do
if type(val) == "table" then
ngx.say(key, ": ", table.concat(val, ", "))
else
ngx.say(key, ": ", val)
end
end
';
}
Now when I call the app like this:
mytestdevbox2:/var/www/nsps2# curl -i -X GET http://localhost/widgets/widget?name=testname&loc=20000 -H "Accept:application/json"
-ash: -H: not found
mytestdevbox2:/var/www/nsps2# HTTP/1.1 200 OK
Server: nginx/1.6.2
Date: Tue, 24 Feb 2015 21:32:44 GMT
Content-Type: text/pain
Transfer-Encoding: chunked
Connection: keep-alive
name: testname
[1]+ Done curl -i -X GET http://localhost/widgets/widget?name=testname
After the system displays the "name: testname" stuff, it just sits there until I hit "enter". After I do that, then it proceeds to display the 1+ stuff.
I'm not too sure what it's doing.
EDIT 2:
Adding quotes to the curl call did fix the problem:
mytestdevbox2:/var/www/nsps2# curl -i -X GET 'http://localhost/widgets/widget?name=testname&loc=20000'
HTTP/1.1 200 OK
Server: nginx/1.6.2
Date: Wed, 25 Feb 2015 12:59:29 GMT
Content-Type: text/pain
Transfer-Encoding: chunked
Connection: keep-alive
loc: 20000
name: testname
mytestdevbox2:/var/www/nsps2#
The problem described in EDIT 1 doesn't have anything to do with your question about nginx and is caused by not quoting the parameters for curl when you execute the command:
curl -i -X GET http://localhost/widgets/widget?name=testname&loc=20000
This is executed as two commands separated by '&': curl -i -X GET http://localhost/widgets/widget?name=testname and loc=20000; that's why you see the output after you already got the prompt back as the first command is now executed in the background. "1+ Done" message is a confirmation that the background process is terminated; it's just shown after you press Enter.
Wrap the URL with the query string in quotes and you should see the expected behavior.
I got a weird issue. I hope someone could help me.
I am new to Zend and I'm writing a RESTfull API.
When I run the curl command as POST method, it calls the putAction() function.
For example, I am run a curl command:
curl -X POST http://localhost/ws/user/post -v
Here is the response:
* About to connect() to localhost port 80 (#0)
* Trying 127.0.0.1...

}
public function putAction() {
echo 'Method = ' . $_SERVER['REQUEST_METHOD'];
$this->sendResponse("From putAction() updating the requested article");
}
[...]
Any ideas ?
EDIT:
I realized that I put this code in my bootstrap:
public function _initRestRoute() {
$front = Zend_Controller_Front::getInstance();
$router = $front->getRouter();
$restRoute = new Zend_Rest_Route($front, array(), array(
'ws',
));
$router->addRoute('rest', $restRoute);
}
When I comment it, it works.
Any explanations ? Thanks!
You shouldn't be having http://localhost/ws/user/post in your request while using the Zend_Rest_Route. This route interprets /user/post as parameters and changes action from post to put. Try http://localhost/ws instead.
See Zend/Rest/Route.php line 208.
