ruby - Chaining sed statements -


i'm running dozen of sed commands each capistranio deploy , wondering, if it's possible chain them 1 single sed command, instead of firing dozens @ server.

task :taskname     {:'foo' => foo, :'bar' => bar, :'foobar' => foobar, :'fubar' => fubar }.each |search, replace|         run "sed -i 's/#{search}/#{replace}/' file.ext"     end end

sed natively accepts dozen of patterns (if reason prefer sed):

{:foo => foo, :bar => bar, :foobar => foobar, :fubar => fubar}.inject("") |acc, k, v|   acc += " -e 's/#{k}/#{v}'" end  run "sed #{acc} file.ext"

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
