Question

我遇到以下情况：我有XML，它们包含base64编码的条目。解码它们似乎不是一个真正的问题（稍后会详细介绍）。解码后的字符串不是UTF-8，但显然是USC2-Internal，可以使用iconv进行转换。现在我想进行更改并返回XML，用转换后的数据替换节点文本条目。

麻烦开始的地方（？）。

问题似乎是base64解码在开头留下了一个无效的5字节集。因此，即使是简单的步骤，也可以将base64解码为字符串，字符串到base64也不起作用。我尝试了几种使用openssl，python等方法。我在这里找到的所有建议都是如此。无论如何 - 要转换的iconv命令确实有效。但是，如果不是“丑陋的字节”，那么再次改回USC-2-Internal将会失败。被忽略了。

这里有谁可以解释这些问题？我可以发布一个例子（只是base64字符串）。

感谢。

以下是XML值的相关部分：

对于我使用的脚本：

set convString to (do shell script "echo " & quoted form of convString & " | python -m base64 -d")

- ＆GT;

Ê{"mTextParam":{"mAlignment":2,"mDefaultRun":[],"mHeight":124,"mHindiDigits":false,"mIndic":false,"mIsVerticalText":false,"mLeading":0,"mLigatures":false,"mRTL":false,"mShadowAngle":135,"mShadowBlur":0,"mShadowColor":0,"mShadowOffset":10,"mShadowOpacity":100,"mShadowVisible":false,"mStyleSheet":{"mBaselineShift":{"mParamValues":[[0,0]]},"mFillColor":{"mParamValues":[[0,16777215]]},"mFillOverStroke":{"mParamValues":[[0,true]]},"mFillVisible":{"mParamValues":[[0,true]]},"mFontName":{"mParamValues":[[0,"MinionPro-Regular"]]},"mFontSize":{"mParamValues":[[0,100]]},"mKerning":{"mParamValues":[[0,0]]},"mStrokeColor":{"mParamValues":[[0,16777215]]},"mStrokeVisible":{"mParamValues":[[0,false]]},"mStrokeWidth":{"mParamValues":[[0,1]]},"mText":"Some ˆzug¸l straﬂe.","mTracking":{"mParamValues":[[0,-24]]},"mTsumi":{"mParamValues":[[0,0]]}},"mTabWidth":400,"mWidth":1533},"mVersion":1}.

这个字符串是USC-2的味道使其可读，尤其是mText值，我使用iconv来打开字符串的备份。

set convString to do shell script "echo | iconv -f UCS-2-INTERNAL -t utf-8 " & quoted form of buPath

- ＆GT;

"ۦ{\"mTextParam\":{\"mAlignment\":2,\"mDefaultRun\":[],\"mHeight\":124,\"mHindiDigits\":false,\"mIndic\":false,\"mIsVerticalText\":false,\"mLeading\":0,\"mLigatures\":false,\"mRTL\":false,\"mShadowAngle\":135,\"mShadowBlur\":0,\"mShadowColor\":0,\"mShadowOffset\":10,\"mShadowOpacity\":100,\"mShadowVisible\":false,\"mStyleSheet\":{\"mBaselineShift\":{\"mParamValues\":[[0,0]]},\"mFillColor\":{\"mParamValues\":[[0,16777215]]},\"mFillOverStroke\":{\"mParamValues\":[[0,true]]},\"mFillVisible\":{\"mParamValues\":[[0,true]]},\"mFontName\":{\"mParamValues\":[[0,\"MinionPro-Regular\"]]},\"mFontSize\":{\"mParamValues\":[[0,100]]},\"mKerning\":{\"mParamValues\":[[0,0]]},\"mStrokeColor\":{\"mParamValues\":[[0,16777215]]},\"mStrokeVisible\":{\"mParamValues\":[[0,false]]},\"mStrokeWidth\":{\"mParamValues\":[[0,1]]},\"mText\":\"Some özugül straße.\",\"mTracking\":{\"mParamValues\":[[0,-24]]},\"mTsumi\":{\"mParamValues\":[[0,0]]}},\"mTabWidth\":400,\"mWidth\":1533},\"mVersion\":1}"

问题在于回归的方式如上所述，即使第一个解码后的字符串也无法转换回base64。对于base64压缩，我尝试了openssl base64 它返回一个错误：

sh：-c：line0：寻找匹配时的意外EOF

希望这有助于使问题更清晰（或者我正在做的错误）。

昨天的答案已经消失了？！幸运的是我记住了步骤。

但是，只是为了扩展关于Murmel关于JSON的正确注释的原始问题。我没有JSON的经验，但从有关它的阅读中我感觉它并不太复杂。

是否有推荐的方式（对于我的工作流程）将JSON转换为＆＃39; .plist＆＃39; XML和返回。从阅读到目前为止，两者将涵盖或多或少相同的数据类型 - 对于我的工作流程（或问题）。

如果有办法，理想的工作流程：

获取XML值
从base64解压缩
转换为UTF
将JSON转换为PLIST
将PLIST连接到用户界面
用户具有可读文本（任何语言），可以编辑文本，字体，字体大小和样式
将PLIST转换为JSON
将JSON转换为USC2-Internal
压缩到base64
替换XML值。

一个简单的文字示例：

Arial Bold 。

至少会改变JSON（PLIST）值：

＆＃34; mFontName＆＃34; {＆＃34; mParamValues＆＃34;：[[0，＆＃34; ArialMT＆＃34;]，[7，＆＃34; ArialMT粗体＆＃34;] [8＆＃34; ArialMT粗体＆＃34]，[9＆＃34; ArialMT粗体＆＃34]，[10，＆＃34; ArialMT粗体＆＃34;]]}。

＆＃34; mText＆＃34;：＆＃34; Arial Bold＆＃34;。

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"><plist version="1.0"><dict><key>mFont</key><array><array><real>0</real><string>ArialMT</string></array><array><real>7</real><string>ArialMT-Bold</string></array><array><real>8</real><string>ArialMT-Bold</string></array><array><real>9</real><string>ArialMT-Bold</string></array><array><real>10</real><string>ArialMT-Bold</string></array></array><key>mText</key><string>Arial Bold</string></dict></plist>

如果我的编辑没有意义，请忽略。

工作流程base64文本 - ＆gt; iconv charset conversion - ＆gt;修改文本和向后（OS X）
