根因分析

io.Reader 返回的字节数少于请求数且未返回错误，违反了 io.Reader 契约。

English

An io.Reader returned fewer bytes than requested without returning an error, violating the io.Reader contract.

解决方案

  1. 95% 成功率 
    Use io.ReadFull to ensure the exact number of bytes are read.
  2. 90% 成功率 
    Loop over io.Read until the desired count is reached or an error occurs.

无效尝试

常见但无效的做法:

  1. 95% 失败

    This leads to data corruption and undefined behavior.

  2. 80% 失败

    The buffer size doesn't affect the reader's behavior; it may still return short reads.
