通过烧瓶对csv文件运行查询

Question

我不是程序员，我正在努力学习并将其用于作业。我需要使用烧瓶休息 API 来搜索数据并将数据从 CSV 文件提取到页面。目标是让用户在 /logcheck/ 上插入字符串，这将触发在 csv 文件中搜索 并提取整行数据并返回结果。

CSV 样本和位置 /家/日志/ 以及 CSV 文件内容的示例截图如下： [在此处输入图片描述][1] [1]：https://i.stack.imgur.com/GQpDb.png

烧瓶代码如下：

import csv
from io import StringIO
import sys
from flask import Flask, request, send_file, jsonify, Response, render_template
from flask.helpers import make_response

csv_file = csv.reader(open('/home/logs/containerlogs.csv', "r"), delimiter=",")


@app.route('/logcheck/<user_input>', methods=['GET'])
def logcheck(user_input):
    healthy = request.form ['healthy']
    unhealthy = request.form ['unhealthy']
if user_input not healthy or not unhealthy:
    return make_response("Please try again./n Only word /logcheck/healthy or logcheck/unhealthy)
else:
    for row in csv_file:
        if user_input == row[0 or 1 or 2 or 3 or 4 or 5]:
            return make_response (print (row))

提前致谢。

代码如下：

#!/usr/bin/python3
import csv, json
from flask import Flask, make_response

csv_rows = []
with open('containerlogs.csv', "r") as o:
    csv_file = csv.reader(o, delimiter=",")
    for row in csv_file:
        csv_rows.append(row)
    o.close()

app = Flask(__name__)

@app.route('/logcheck/<user_input>', methods=['GET'])
def logcheck(user_input):
    #healthy = request.form ['healthy']     # Why request.form?
    #unhealthy = request.form ['unhealthy'] # If requests.form it works only when methods=['POST'].
    #if user_input not healthy or not unhealthy:
    if user_input != 'healthy' and user_input != 'unhealthy':
        return make_response("Please try again./n Only word /logcheck/healthy or logcheck/unhealthy")
    else:
        rows = '' #[]
        for row in csv_rows:
            if user_input in row:
                #rows.append(row)
                rows += ', '.join(row) + '<br>'
        return make_response (rows) #json.dumps (rows)

app.run("0.0.0.0", 8080)
