The __parser__ automatically removes the chunked transfer coding when it is the last encoding in the list. However, it also discards the chunk extensions and does not provide a way to determine the boundaries between chunks. Advanced applications which need to access the chunk extensions or read complete individual chunks may use a callback interface provided by __parser__:

Advanced applications which need to access the chunk extensions or read complete individual chunks may use a callback interface provided by当分块传输编码位于编码列表的末尾时，__parser__ 会自动将其移除。但在此过程中，解析器会丢弃分块扩展，也不提供确定分块之间边界的方法。对于需要访问分块扩展或读取完整分块的高级应用，可以使用 __parser__: 提供的回调接口：

For the ultimate level of control, a caller can manually compose the chunk itself by first emitting a header with the correct chunk body size, and then by emitting the chunk body in multiple calls to the stream write function. In this case the caller is responsible for also emitting the terminating CRLF (`"\r\n"`):

Callers can take over the generation and management of the extensions buffer by passing a non-owning string. Note that this requires the string contents to adhere to the correct syntax for chunk extensions, including the needed double quotes for values which contain spaces:
