当从PhantomJS中发送时，HTTP内容类型标头和正文不会被传输

当启动内容类型为header和body的HTTP DELETE请求时，这两个元素是：

当从Chrome内部发起请求时，收到良好效果， 从PhantomJS中启动请求时未收到。 两人中哪一人的行为符合标准

需要注意的是，在这两种情况下，客户机和服务器是相同的

下面是服务器级别的请求日志

从PhantomJS中发送的请求日志

从Chrome内部发送的请求日志

在第9.7章中规定了删除方法。它没有在描述文本中指定与POST和PUT相关的封闭实体消息体的任何内容

从您的日志中可以明显看出，PhantomJS甚至不发送消息体，因此不需要包含内容类型，因为它假定不会使用它，因为它没有定义。看起来Chrome发送消息的主体是不顾一切的

第6.7章中包含以下内容：

删除请求上的主体没有定义的语义。注意 在删除请求上发送正文可能会导致某些现有的错误 实现拒绝请求

由于PhantomJS 1.x基于三年多以前的WebKit初稿版本，所以它的行为是这样的。另一方面，Chrome可能已经实施了提议的草案，并主动向机构发送删除请求。有关更多信息，请参阅

如果您的操作依赖于DELETE方法的消息体，那么您应该更改实现，以便您删除的资源完全由URI定义。

我的答案有帮助吗？有什么问题吗？有。我设计了一个RESTAPI，客户端可以在其中发送一个主体以及GET和DELETE请求。我认为在服务器中发送JSON比在URL中发送所有请求数据要干净得多。根据您的回复，我决定暂时审查API的设计，并将所有请求数据放在URL中以获取和删除。我认为修复phantomjs中的此错误比期望每个人都更改API更有意义…@shi phantomjs是开源的。您可以在GitHub上分叉它，修复代码并创建一个pull请求。
