哪一个吉大港 回返状况
原标题:Which HTTP Response Status to Return

I have a REST operation. User wants to delete an object.

  • If a database error occurs
  • When writing to response with response.getWriter() if IOException occurs.

如果我回到客户一方,哪一种地位法(500,503等)。 (千美元) 我指的是什么更方便?

最佳回答

这里最适当的500条声音,除非您know <>m>由于服务器超负荷运行。

如果response.getWriter(>(或后来向作者发出的呼吁)扔下了IOException,那么,我怀疑你在能够有益地影响客户收到答复的阶段之后再行。

问题回答

If it s a temporary error, 503 is appropriate as it generally means "retry later". I don t think most database errors fall into that category though. In most cases a generic 500 is the best response. There aren t many options in the 500 list:

如果由于删除是无效的作业,或像禁止的那类行动,那么,禁止的403起是我使用的:

你没有为我们提供足够的信息,使我们能够回答关于数据库错误的问题。 如果数据库的错误是由于违反参考性完整性限制造成的,那么,由于这是客户的错误,你应当退回400个错误。

你对哪类数据库错误感到关切?
