bitcoin 要求 Content-Length 头，但有几个 JSON-RPC 库不提供它。当 Content-Length 头缺失时，bitcoin 返回 500 Internal Server Error。

你能具体说是哪些 JSON 库不提供 Content-Length 吗？能记录下来就好了。
我想我们应该尝试支持没有 Content-Length 参数的情况。不过我不想大改流处理，即使不得不一次读一个字符。
补充：前提是真有不支持 Content-Length 的库存在。

bitcoin requires the Content-Length header, but several JSON-RPC libraries do not provide it. When the Content-Length header is absent, bitcoin returns 500 Internal Server Error.

Can you be more specific about which JSON libraries don't provide Content-Length ? It'd be nice to document that.
I guess we should try to support the case where there's no Content-Length parameter. I don't want to rip and replace streams though, even if it has to read one character at a time.
Edit: That is, assuming there actually are any libraries that don't support Content-Length.
