saml Java Inflater引发DataFormatException“无效代码长度集”
我正在用充气机解压一个简单的请求。由于这个值是用GZIP压缩的,所以我设法将“true”传递给充气器构造函数,以提供与这种格式的兼容性。然而,膨胀行抛出DataFormatException
private String decodeMessage(String SAMLContent) {
try {
//URLDecode, Base64 and inflate data
//URLDecode
SAMLContent = URLDecoder.decode(SAMLContent, "UTF-8");
//Base64 decoding
byte[] decode = Base64.getDecoder().decode(SAMLContent);
SAMLContent = new String(decode, "UTF-8");
//SAMLContent = new String(Base64.getDecoder().decode(SAMLContent), "UTF-8");
//Inflating data
try {
byte[] inflated = new byte[(10 * SAMLContent.getBytes("UTF-8").length)];
Inflater i = new Inflater(true);
i.setInput(SAMLContent.getBytes("UTF-8"), 0, SAMLContent.getBytes("UTF-8").length);
//The following line throws DFException
int finalSize = i.inflate(inflated);
SAMLContent = new String(SAMLContent.getBytes("UTF-8"), 0, finalSize, "UTF-8");
i.end();
} catch (DataFormatException ex) {
JOptionPane.showMessageDialog(null, "DFE: " + ex.getMessage()); //Returns "invalid code length set"
}
} catch (UnsupportedEncodingException ex) {
JOptionPane.showMessageDialog(null, "UEE: " + ex.getMessage());
}
return SAMLContent;
}
例外情况在第20行提出。我试图复制的工作流程是
- 正在复制请求的值(This one for instance)
- 使用this URL decoder to decode it(左下角文本框)
- 将第二步的结果粘贴到此Base64decoder + inflater中,以获取原始XML,如最后一页的第三个文本框所示李>
