我不明白问题是什么。数据已从服务器正确检索，但在发布时显示错误。 帮我。

关于ios - 如何在 objective c 中将 SOAP 数据发布到服务器，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38074657/
出于纯粹的兴趣，我很好奇如何按顺序创建PI，而不是在过程结果之后生成数字，而是让数字在过程本身生成时显示。如果是这种情况，那么数字可以自行产生，我可以对以前看到的数字实现垃圾收集，从而创建一个无限系列。结果只是在Pi系列之后每秒生成一个数字。这是我通过互联网筛选的结果:这是流行的计算机友好算法，类机器算法:defarccot(x,unity)xpow=unity/xn=1sign=1sum=0loopdoterm=xpow/nbreakifterm==0sum+=sign*(xpow/n)xpow/=x*xn+=2sign=-signendsumenddefcalc_pi(digits
我的目标是转换表单输入，例如“100兆字节”或“1GB”，并将其转换为我可以存储在数据库中的文件大小(以千字节为单位)。目前，我有这个:defquota_convert@regex=/([0-9]+)(.*)s/@sizes=%w{kilobytemegabytegigabyte}m=self.quota.match(@regex)if@sizes.include?m[2]eval("self.quota=#{m[1]}.#{m[2]}")endend这有效，但前提是输入是倍数(“gigabytes”，而不是“gigabyte”)并且由于使用了eval看起来疯狂不安全。所以，功能正常，
我正在尝试使用ruby和Savon来使用网络服务。测试服务为http://www.webservicex.net/WS/WSDetails.aspx?WSID=9&CATID=2require'rubygems'require'savon'client=Savon::Client.new"http://www.webservicex.net/stockquote.asmx?WSDL"client.get_quotedo|soap|soap.body={:symbol=>"AAPL"}end返回SOAP异常。检查soap信封，在我看来soap请求没有正确的命名空间。任何人都可以建议我
我想安装一个带有一些身份验证的私有(private)Rubygem服务器。我希望能够使用公共(public)Ubuntu服务器托管内部gem。我读到了http://docs.rubygems.org/read/chapter/18.但是那个没有身份验证-如我所见。然后我读到了https://github.com/cwninja/geminabox.但是当我使用基本身份验证(他们在他们的Wiki中有)时，它会提示从我的服务器获取源。所以。如何制作带有身份验证的私有(private)Rubygem服务器？这是不可能的吗？谢谢。编辑:Geminabox问题。我尝试“捆绑”以安装新的gem..
如何在buildr项目中使用Ruby？我在很多不同的项目中使用过Ruby、JRuby、Java和Clojure。我目前正在使用我的标准Ruby开发一个模拟应用程序，我想尝试使用Clojure后端(我确实喜欢功能代码)以及JRubygui和测试套件。我还可以看到在未来的不同项目中使用Scala作为后端。我想我要为我的项目尝试一下buildr(http://buildr.apache.org/)，但我注意到buildr似乎没有设置为在项目中使用JRuby代码本身!这看起来有点傻，因为该工具旨在统一通用的JVM语言并且是在ruby中构建的。除了将输出的jar包含在一个独特的、仅限ruby
我正在使用的第三方API的文档状态:"[O]urAPIonlyacceptspaddedBase64encodedstrings."什么是“填充的Base64编码字符串”以及如何在Ruby中生成它们。下面的代码是我第一次尝试创建转换为Base64的JSON格式数据。xa=Base64.encode64(a.to_json) 最佳答案 他们说的padding其实就是Base64本身的一部分。它是末尾的“=”和“==”。Base64将3个字节的数据包编码为4个编码字符。所以如果你的输入数据有长度n和n%3=1=>"=="末尾用于填充n%
我主要使用Ruby来执行此操作，但到目前为止我的攻击计划如下:使用gemsrdf、rdf-rdfa和rdf-microdata或mida来解析给定任何URI的数据。我认为最好映射到像schema.org这样的统一模式，例如使用这个yaml文件，它试图描述数据词汇表和opengraph到schema.org之间的转换:#SchemaXtoschema.orgconversion#data-vocabularyDV:name:namestreet-address:streetAddressregion:addressRegionlocality:addressLocalityphoto:i
exe应该在我打开页面时运行。异步进程需要运行。有什么方法可以在ruby中使用两个参数异步运行exe吗？我已经尝试过ruby命令-system()、exec()但它正在等待过程完成。我需要用参数启动exe，无需等待进程完成是否有任何rubygems会支持我的问题？ 最佳答案 您可以使用Process.spawn和Process.wait2:pid=Process.spawn'your.exe','--option'#Later...pid,status=Process.wait2pid您的程序将作为解释器的子进程执行。除

我正在为一个项目制作一个简单的shell，我希望像在Bash中一样解析参数字符串。foobar"helloworld"fooz应该变成:["foo","bar","helloworld","fooz"]等等。到目前为止，我一直在使用CSV::parse_line，将列分隔符设置为""和.compact输出。问题是我现在必须选择是要支持单引号还是双引号。CSV不支持超过一个分隔符。Python有一个名为shlex的模块:>>>shlex.split("Test'helloworld'foo")['Test','helloworld','foo']>>>shlex.split('Test"
