`$response->getBody()->getContents()` 并不能保证拿到完整内容，PSR-7 里的原话：

> Each stream instance will have various capabilities: it can be read-only, write-only, or read-write. It can also allow arbitrary random access (seeking forwards or backwards to any location), or only sequential access (for example in the case of a socket, pipe, or callback-based stream).
>
> Finally, StreamInterface defines a __toString() method to simplify retrieving or emitting the entire body contents at once.
