Get request response is in weird format - ruby-on-rails

I send a get request to a local (separate from app) jetty web server
RestClient.get("ip/command/core/get-version", {})
Then I do a JSON.parse() on the response.
As a result I get
{"revision"=>"r2407", "full_version"=>"2.5 [r2407]", "full_name"=>" [r2407]", "version"=>"2.5"}
What's wrong? How do I turn it into a hash, so I can extract the full_version property?

String returned by service is html encoded. Try decoding it first:
JSON.parse(CGI.unescape_html(response_body))

Your JSON response looks to be encoded into HTML entities.
If you are using Ruby, try decoding the response using CGI.unescape_html prior to running JSON.parse. Running the result of that method through JSON.parse should give you your hash.

Postman gives right response,but restassured returns empty for same request?

As you can see that postman returns expected result
but res.asString() gives [] in the blow code,can you tell me why?
def "simple test"(){
String url="http://xxx.xxx.xxx/assessment/api/Test.html"
when:""
io.restassured.response.Response res=RestAssured.given().header("Content-Type", "application/x-www-form-urlencoded").formParam("Action", "getDiagnosisList").formParam("Data", "[{\"subject\":\"冠心病\",\"option\":\"是\"}]").post(url)
then:""
res.prettyPrint()=="[\"身体健康状态不良\",\"医疗处置\"]"
}
It turns out that Chinese characters can't be encoded correctedly by default,after adding blow code,everything worked as expected:
RestAssured.given().config(RestAssured.config().encoderConfig(EncoderConfig.encoderConfig().defaultContentCharset("UTF-8")))
Maybe the request did via postman has not been cached, and on the other hand the same request via restassured is using some kind of cache. Recently I was having a similar issue because of it was hitting the varnish server. I'd recommend you to take a look at the response headers from both postman and restassured.

Rails not getting params from HTTP request

I'm trying to POST the following data to a Rails server (running on WebRick) from Android.
<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
<data>
<email>email.test#name.com</email>
<password>APassw0rd</password>
<remember_me>1</remember_me>
</data>
Now, the funny thing is that these data never show up in the params field in the controller.
Webrick does not output any parsing error. (And I guess it would post an error if it received a POST with no data attached:
Started POST "/users/sign_in.xml" for 192.168.1.94 at 2012-12-14 17:33:20 +0100
Processing by Users::SessionController#create as XML
Completed 500 Internal Server Error in 22643ms
I also found no trace of the data in the request.env variable. Actually, I see no HTTP_BODY in the dump fields. How can one see the raw body of the request? Would webrick really not complain if it received a POST with no attached data?
request.env would show the data as an IO object so you wouldn't be able to see your xml directly.
request.raw_post should return the raw data.
For rails to try and parse your xml into the params hash directly you need to set the content type of the request to application/xml. The 'processing as xml' stuff means that rails will try to render an xml response and doesn't necessarily have any bearing on the format of the posted data

RestResponse is null on POST request using RestSharp

I am making a POST request with RestSharp (on windows phone 7.1 client). I sent string to a service in a request body. Looks like the service is successfully called and it returns proper value (integer), however response object is null:
client.ExecuteAsync<T>(request, (response) => {
data = response.Data; // response is null in debugger
});
I cant understand why is that so.
<T> isn't a valid value for that call. I'm not sure that would even build there unless you've wrapped it in a generic method.
Also, is the response coming back as plain text? What's the Content-Type returned? Most likely, you should just use ExecuteAsync(request, callback) without the generic parameter and grab the data out of response.Content which is a string of the response body. response.Data is for the automatically deserialized XML or JSON (or custom) response if you use the generic method overload that specifies a type to deserialize to.
This seems to be an ongoing issue with RestSharp asynchronous calls - for HTTP transport errors ErrorException object is useless (returns null). Check the StatusCode property if it returns with anything but HttpStatusCode.OK. StatusDescription is not extremely useful either as it doesn't match complete status message from server response payload.

Trouble handling HTTP responses and parsing JSON data

I am using Ruby on Rails 3 and I would like to solve an issue with the following code where a web client application receive back some JSON data from a web service application that uses a Rack middleware in order to respond.
In the web client app model I have
response_parsed = JSON.parse(response.body)
if response_parsed["account"]
...
else
return response
end
In the above code the response.body come back from the web service app that uses a Rack middleware to respond to the web client:
accounts = Account.where(:id => ids)
[200, {'Content-Type' => 'application/json'}, accounts.to_json] # That is, response.body = accounts.to_json
Data transmission is ok, but I get the following error
TypeError
can't convert String into Integer
*Application Trace*
lib/accounts.rb:107:in `[]'
The line 107 corresponds to
if response_parsed["account"]
...
Where and what is the problem? How to solve that?
If I try to debug the respons.body I get
# Note: this is an array!
"[{\"account\":{\"firstname\":\"Semio\",\"lastname\":\"Iaven\"\"}}]"
If I'm saying something you already realize, forgive me.
It looks like your response is a one-element array with a hash in it as the first element. Because the response is an array, when you use the [] it is expecting a integer representing the index of the item in the array you'd like to access, and that is what the error message means--it expected that you'd tell it the integer value of the item you wanted, but instead you gave it a string.
If you instead do:
response_parsed[0]['account']
It seems like you'd get what you want.

Parse JSON string to detect error response

i'm working with a server which response using the JSON format.
when the request contain valid data they respond with a string like this
{"data":{"results":[{"Branch":"ACCT590006"}]}}
but if the parameters of the request are incorrect the response goes like this
{"error":{"errors":[{"domain":"global","reason":"invalid","message":"Invalid
Params"}],"code":98865,"message":"Invalid
param value"}}
So the questions are how i can determine when the response of the server contains a error string using the TJSONObject object and additionally parse the JSON string to show the messages and error codes like this.
Failed reason : invalid
Message : Invalid params
Code: 98865
message : invalid param value.
I've worked a little with JSON, an every time I've parsed from code(delphi 7). But i've searched a little bit, and here you may find the answer of your question:
http://edn.embarcadero.com/print/40882
and with a little adaption this should work.
Best regards,
Radu
