这是我为实现itunes_verification而编写的一段代码。
http://gist.github.com/raw/622038/b32accd30e86f7c714f2cffefd19857f558c8d97/gistfile1.rb
ItunesVerification.verify_apple_receipt（ “wefwfrw”）
但是，它始终从itunes服务器抛出{“exception”=＆gt;“java.lang.NullPointerException”，“status”=＆gt; 21002}。
#<HTTParty::Response:0x46d59a8 @parsed_response={"exception"=>"java.lang.NullPointerException", "status"=>21002}, @response=#<Net::HTTPOK 200 Apple WebObjects readbody=true>, @headers={"x-webobjects-loadaverage"=>["0"], "x-apple-application-site"=>["SB"], "expires"=>["Thu, 14 Oct 2010 04:24:12 GMT"], "connection"=>["keep-alive"], "edge-control"=>["no-store", "max-age=0"], "pod"=>["100"], "date"=>["Thu, 14 Oct 2010 04:24:12 GMT"], "x-apple-max-age"=>["0"], "x-apple-application-instance"=>["1000407"], "x-apple-woa-inbound-url"=>["/WebObjects/MZFinance.woa/wa/verifyReceipt?output=json&receipt-data=d2Vmd2U%3D%0A"], "content-length"=>["62"], "set-cookie"=>["Pod=100; version=\"1\"; expires=Sun, 14-Nov-2010 05:24:12 GMT; path=/; domain=.apple.com", "mzf_in=1000407; version=\"1\"; path=/WebObjects; domain=.apple.com"], "x-apple-lokamai-no-cache"=>["true"], "cache-control"=>["no-transform", "private", "no-cache", "no-store", "must-revalidate", "max-age=0"], "pragma"=>["no-cache"]}>
此外，我传递的字符串被编码为Base64。
我尝试过其他选项，例如将密钥从“正文”更改为“查询”。
这非常紧迫，我们将非常感谢任何帮助。
