python 上传文件（upload），保存临时文件，再以csv和xls格式读取

1. UPload上传保存临时文件

async def upload(file: UploadFile = File(...)):
    file_name = file.filename.split(".")[0]
    file_suffix = file.filename.split(".")[1]
    cur_path = os.path.abspath('.') + os.sep + "upload" + os.sep
    full_path = cur_path + file_name + "_file"
    # 保存文件
    with open(full_path, 'wb') as fw:
        res = await file.read()
        fw.write(res)
    
    context = {"status": 200, "msg": "success"}
    return

2. 读取csv

import csv
def read_csv(full_path):
    with codecs.open(full_path, 'r', 'gbk', errors='ignore') as fw:
        lines = csv.reader(fr)
        for line in lines:
            print(line)

3. 读取xls

import xlrd
def read_xls(full_path):
    wb = xlrd.open_workbook(full_path)
    sheet = wb.sheet_by_index(0) # 获取第一个sheet表数据
    for raw in range(1, sheet.nrows - 1):
        lines = sheet.row_values(raw)
        print(lines)
