java - GET HTTP request payload -


i designing api , wonder if fine send json payload on request?

in other question payloads of http request methods, can find according this link:

  • head - no defined body semantics.
  • get - no defined body semantics.
  • put - body supported.
  • post - body supported.
  • delete - no defined body semantics.
  • trace - body not supported.
  • options - body supported no semantics (maybe in future).

does mean should not send request payload? there risks so?

  • like having http client libraries incapable of sending such payload?
  • or java api code not being portable on application servers?
  • anything else?

i found out elasticsearch using such payload on request:

$ curl -xget 'http://localhost:9200/twitter/tweet/_search?routing=kimchy' -d '{     "query": {         "filtered" : {             "query" : {                 "query_string" : {                     "query" : "some query string here"                 }             },             "filter" : {                 "term" : { "user" : "kimchy" }             }         }     } } '

so if popular libary , nobody complains, perhaps can same?

by way, i know if ok mix querystring parameters , json payload? elasticsearch query does. if so, there rules know arguments should querystring parameters, or payload parameters?

here can read: http request body

roy fielding's comment including body request.

yes. in other words, http request message allowed contain message body, , must parse messages in mind. server semantics get, however, restricted such body, if any, has no semantic meaning request. requirements on parsing separate requirements on method semantics.

so, yes, can send body get, , no, never useful so.

this part of layered design of http/1.1 become clear again once spec partitioned (work in progress).

....roy

then don't understand why never useful, because makes sense in opinion send complex queries server wouldn't fit on queryparam or matrixparam. think elasticsearch api designers think same...

i planning design api can called that:

curl -xget 'http://localhost:9000/documents/inbox?pageindex=0&pagesize=10&sort=title'  curl -xget 'http://localhost:9000/documents/trash?pageindex=0&pagesize=10&sort=title'  curl -xget 'http://localhost:9000/documents/search?pageindex=0&pagesize=10&sort=title' -d '{     "somesearchfilter1":"filtervalue1",     "somesearchfilter2":"filtervalue2",     "somesearchfilterlist": ["filtervalue3","xxx"]     ... lot more ... } '

does seem fine you? based on above considerations.

having response vary based on request body break caching. don't go there.

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
