java - ArrayIndexOutOfBoundsException: 1 in web server -


i have made simple restful web service using tomcat web container , jersey library.

i have overridden post method, rest default settings used.

while sending post query curl server machine expected response. other machine also, getting expected response get query, post java.lang. arrayindexoutofboundsexception: 1 exception error. post method goes this:

@post @produces(mediatype.text_plain) public string post(string str) {   string[] parts = str.split("&");   string[] param1 = parts[0].split("=");//value1=param1[1] (one/two): query type   string[] param2 = parts[1].split("=");//value2=param2[1]    string[] param3 = parts[2].split("=");//value3=param3[1]    string[] param4 = parts[3].split("=");//value4=param4[1]     if(param1[1].equals("one")){       return hashgenerator(param2[1],param3[1]);   }else if(param1[1].equals("two")){       return saveinput(param2[1],param3[1],param4[1]);   }   return "unexpected query"; }

response server :

can please suggest fault....

you asking array elements might not exist, splitting input string on character , not checking length of array risks throwing arrayindexoutofboundsexception when try use these non-existent array elements later (an input string of foo&bar it).

furthermore, should never form data / query string parsing yourself, there many edge cases. use library, or better still use framework (jersey) - it, part of jax-rs, has support form params. see an example here.

or make more restful , use pathparams take parameters explicitly in request, if that's option.

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
