[英]Getting bad content in trailing section exception, when parsing xml produced by C# client in a GAEJ app
I am trying to POST a potentially large chunk of xml from a C# client to a GAEJ app, and then parse it into a DOM document. 我正在尝试从C#客户端向GAEJ应用发布可能很大的xml块,然后将其解析为DOM文档。
I've managed to get the documentbuilder to parse the xml by parsing the request data into a string and then trimming it, as such: 我已经设法通过将请求数据解析为字符串,然后对其进行修整,来使documentbuilder解析xml,如下所示:
String xml;
BufferedReader rdr = req.getReader();
String line;
StringBuilder result = new StringBuilder();
while ((line = rdr.readLine()) != null) {
result.append(line);
}
xml = result.toString();
db = dbf.newDocumentBuilder();
Document doc = db.parse(new InputSource(new StringReader(xml.trim())));
However the GAEJ app should be as efficient as possible and reading the potentially large xml input to a string line by line, as opposed to feeding the sourcestream to the parser, seems quite bad. 但是,GAEJ应用程序应尽可能高效,并且将可能较大的xml输入逐行读取到字符串中,而不是将sourcestream馈送到解析器,这似乎很糟糕。 I would like the following to work:
我希望以下工作:
Document doc = db.parse(request.getInputStream());
But then I always get "org.xml.sax.SAXParseException: Content is not allowed in trailing section." 但是然后,我总是收到“ org.xml.sax.SAXParseException:尾部不允许出现内容”。 If I dump the contents of the request.getInputStream() call to the console I can see some box-characters after the final closing tag, but I'm not sure how they got there (the clientside is using UTF-8 encoding), or how to remove them from the input stream.
如果我将request.getInputStream()调用的内容转储到控制台,我可以在最后的结束标记后看到一些方框字符,但是我不确定它们如何到达那里(客户端使用的是UTF-8编码),或如何从输入流中删除它们。 Thanks!
谢谢!
