Question

我正在使用下面的代码从http://www.ietf.org/rfc/rfc2849.txt中读取示例6，我正在使用unboundid-ldapsdk版本4.0.6。我得到以下异常 Entries read:3 Entries with error:1 LDIFException(lineNumber=23, mayContinueReading=true, message='The record starting at or near line number 23 contains a line that does not begin with an attribute name followed by a colon.', dataLines='dn: ou=PD Accountants, ou=Product Development, dc=airius, dc=com{end-of-line}changetype: modrdn{end-of-line}newrdn: ou=Product Development Accountants{end-of-line}deleteoldrdn: 0{end-of-line}newsuperior: ou=Accounting, dc=airius, dc=com{end-of-line}dn: cn=Paula Jensen, ou=Product Development, dc=airius, dc=com{end-of-line}changetype: modify{end-of-line}add: postaladdress{end-of-line}postaladdress: 123 Anystreet $ Sunnyvale, CA $ 94086{end-of-line}-{end-of-line}') at com.unboundid.ldif.LDIFReader.parseAttributes(LDIFReader.java:2744) at com.unboundid.ldif.LDIFReader.decodeEntry(LDIFReader.java:2070)

UnboudId实现中是否缺少用于解析LDIF文件的内容？尝试读取实际的LDIF文件时遇到类似的错误。我浏览了文档，其中提到它是按照RFC 2849进行的。

示例代码-

Answer 1

您的源代码的这两行之间没有空的分隔线：

{
    "id": 41,
    "username": "J.Son",
}

因此，第二条更改记录被解析为+ "newsuperior: ou=Accounting, dc=airius, dc=com\n" + "# Modify an entry: add an additional value to the postaladdress\n"更改记录的延续。

UnboundID LDIFReader无法读取条目
