这个参考代码有什么问题？

我正在尝试编译一份 latex 文档，但 bbl 文件中出现了一个奇怪的错误。具体来说，某个参考代码片段给编译器带来了错误：

@inproceedings{FEPPS04,
  author    = {Paola Flocchini and
               Antonio Mesa Enriques and
               Linda Pagli and
               Giuseppe Prencipe and
               Nicola Santoro},
  title     = {Efficient Protocols for Computing the Optimal Swap Edges of a                    Shortest Path Tree},
  booktitle = {Exploring New Frontiers of Theoretical Informatics, {IFIP} 18th World
               Computer Congress, {TC1} 3rd International Conference on Theoretical
               Computer Science (TCS2004), 22-27 August 2004, Toulouse, France},
  pages     = {153--166},
  year      = {2004},
  url       = {http://dx.doi.org/10.1007/1-4020-8141-3_14},
  doi       = {10.1007/1-4020-8141-3_14},
  timestamp = {Wed, 16 Jul 2014 12:43:29 +0200},
  biburl    = {http://dblp.uni-trier.de/rec/bib/conf/ifipTCS/FlocchiniEPPS04},
  bibsource = {dblp computer science bibliography, http://dblp.org}
}

知道可能是什么问题吗？我在 bbl 中有几个引用，但其他引用在编译过程中都没有导致任何问题。如果其他方法都不起作用，我会用另一个引用替换这个引用，但我想知道它可能是什么问题，因此我在这里提问。

答案1

由于 URL 字符串相当长，并且字段url和doi字段都包含_（下划线）字符，因此我建议您加载网址包裹。
