我想知道如何将ExtractZipFile插件安装到最新的cordova 2.3中。我试图使插件正常工作,但没有成功。
链接到插件
https://github.com/phonegap/phonegap-plugins/tree/master/Android/ExtractZipFile
希望可以有人帮帮我。
问候
最佳答案
我修改了Vishal Rajpal(ExtractZipFile插件的作者)代码以符合cordova插件结构,如Plugin Development Guide和Developing a Plugin on Android中所述。
放在org / apache / cordova / plugin / ExtractZipFilePlugin.java下的src目录中的Java代码

String filename = args.getString(0);
unzip(filename, callbackContext);
return true;
}
return false;
}
private void unzip(String filename, CallbackContext callbackContext)
{
File file = new File(filename);
String[] dirToSplit = filename.split(File.separator);
String dirToInsert = "";
for (int i = 0; i < dirToSplit.length - 1; i++)
{
dirToInsert += dirToSplit[i] + File.separator;
}
BufferedOutputStream dest = null;
BufferedInputStream is = null;
ZipEntry entry;
ZipFile zipfile;
try
{
zipfile = new ZipFile(file);
Enumeration<? extends ZipEntry> e = zipfile.entries();
while (e.hasMoreElements())
{
entry = (ZipEntry)e.nextElement();
is = new BufferedInputStream(zipfile.getInputStream(entry), 8192);
int count;
byte data[] = new byte[102222];
String fileName = dirToInsert + entry.getName();
File outFile = new File(fileName);
if (entry.isDirectory())
{
outFile.mkdirs();
}
else
{
FileOutputStream fos = new FileOutputStream(outFile);
dest = new BufferedOutputStream(fos, 102222);
while ((count = is.read(data, 0, 102222)) != -1)
{
dest.write(data, 0, count);
}
dest.flush();
dest.close();
is.close();
}
}
}
catch (ZipException e1)
{
callbackContext.error(PluginResult.Status.MALFORMED_URL_EXCEPTION.toString());
return;
}
catch (IOException e1)
{
callbackContext.error(PluginResult.Status.IO_EXCEPTION.toString());
return;
}
callbackContext.success(filename);
}
}
插件声明将放置在res / xml / config.xml中的插件下
<plugin name="ZipPlugin" value="org.apache.cordova.plugin.ExtractZipFilePlugin" />
项目中将包含的JavaScript代码-文件ZipPlugin.js

var ExtractZipFilePlugin = function()
{
};
ExtractZipFilePlugin.prototype.extractFile = function(file, successCallback, errorCallback)
{
cordova.exec(successCallback, errorCallback, "ZipPlugin", "unzip", [file]);
};
使用范例
var ZipClient = new ExtractZipFilePlugin();
ZipClient.extractFile("my_path/my.zip", win, fail);
function win(status)
{
alert('Success ' + status);
}
function fail(error)
{
alert(error);
}
使用cordova 2.4.0成功测试
干杯!
