在烧瓶服务器页面中写入 file.txt

Question

这是我在正常 python 脚本中执行的代码，它可以正常工作，但是当涉及到烧瓶函数时，他创建了 file.txt，但没有写入

app = Flask(__name__)
@app.route('/execute',methods=['POST'])

def execute():
    message = request.get_json(force=True)
    name=message['name']
    path="data/"
    testname="test.txt"
    encodedname="encoded.txt"

    output = open(path+testname, "wb")
    output.write(name.encode('utf-8'))

这里是第一次写作品

    with open(path+testname, 'rb') as infile:
        data = infile.readlines()
        all_data=""
        for oneline in data:
            oneline=oneline.decode('utf-8')
            print(

oneline)
            new_data = re.sub(r'[^\u0600-\u065F\u0670-\u06ef\u0750-\u077f\ufb50-\ufbc1\ufbd3-\ufd3f\ufd50-\ufd8f\ufd50-\ufd8f\ufe70-\ufefc\uFDF0-\uFDFD]+',' ', oneline)
            new_data = re.sub('[\ufd3e\ufd3f]',' ',new_data)
            new_data = remove_punctuations(new_data)
            new_data = new_data+'@\n'
            all_data = all_data+new_data
    cleanedtest = open(path+"cleanToTest.txt",'wb')
    cleanedtest.write(all_data.encode('utf-8'))

但这里没有 (cleanedTest)

Answer 1

您应该使用上下文管理器。您的问题是您需要在写入后关闭该文件。上下文管理器会自动为您完成。

改变这个：

output = open(path+testname, "wb")
output.write(name.encode('utf-8'))

为此：

with open(path+testname, 'wb') as output:
    output.write(name.encode('utf-8'))

也改变这个：

cleanedtest = open(path+"cleanToTest.txt",'wb')
cleanedtest.write(all_data.encode('utf-8'))

为此：

with open(path+"cleanToTest.txt", 'wb') as output:
    output.write(name.encode(all_data.encode('utf-8'))
