根因分析

请求体包含非 UTF-8 编码的数据，例如二进制或 Latin-1。

English

Request body contains non-UTF-8 encoded data, such as binary or Latin-1.

generic

解决方案

  1. 85% 成功率 Specify encoding when reading request body 
    data = await request.body()
text = data.decode('latin-1')  # or 'utf-8' with errors='replace'
  2. 90% 成功率 Use FastAPI's bytes type for raw data 
    from fastapi import UploadFile
@app.post('/upload')
async def upload(file: UploadFile):
    content = await file.read()
    # handle bytes as needed

无效尝试

常见但无效的做法:

  1. Setting app default encoding to latin-1 globally 70% 失败

    Breaks other parts expecting UTF-8.

  2. Ignoring errors with errors='ignore' 60% 失败

    Data loss can occur.
