Question

我使用燒瓶創建聯繫人形成使用瓶時，我想使用這張聯絡表格，發送電子郵件

我不斷收到此錯誤。在我的終端每當我運行python routes.py

File "routes.py", line 25 
    msg = Message(form.subject.data, sender='contact@example.com<script type="text/javascript"> 

SyntaxError: EOL while scanning string literal 

這裏是我的routes.py文件。

@app.route('/contact', methods=['GET', 'POST']) 
def contact(): 
    form = ContactForm() 

    if request.method == 'POST': 
    if form.validate() == False: 
     flash('All fields are required.') 
     return render_template('contact.html', form=form) 
    else: 
     msg = Message(form.subject.data, sender='contact@example.com<script type="text/javascript"> 
/* <![CDATA[ */ 
(function(){try{var s,a,i,j,r,c,l,b=document.getElementsByTagName("script");l=b[b.length-1].previousSibling;a=l.getAttribute('data-cfemail');if(a){s='';r=parseInt(a.substr(0,2),16);for(j=2;a.length-j;j+=2){c=parseInt(a.substr(j,2),16)^r;s+=String.fromCharCode(c);}s=document.createTextNode(s);l.parentNode.replaceChild(s,l);}}catch(e){}})(); 
/* ]]> */ 
</script>', recipients=['your_email@example.com<script type="text/javascript"> 
/* <![CDATA[ */ 
(function(){try{var s,a,i,j,r,c,l,b=document.getElementsByTagName("script");l=b[b.length-1].previousSibling;a=l.getAttribute('data-cfemail');if(a){s='';r=parseInt(a.substr(0,2),16);for(j=2;a.length-j;j+=2){c=parseInt(a.substr(j,2),16)^r;s+=String.fromCharCode(c);}s=document.createTextNode(s);l.parentNode.replaceChild(s,l);}}catch(e){}})(); 
/* ]]> */ 
</script>']) 
     msg.body = """ 
     From: %s <%s> 
     %s 
     """ % (form.name.data, form.email.data, form.message.data) 
     mail.send(msg) 

     return 'Form posted.' 

    elif request.method == 'GET': 
    return render_template('contact.html', form=form) 

Answer 1

使用多行字符串和收盤報價三重引號應該是來]後：

msg = Message(form.subject.data, sender='''contact@example.com<script type="text/javascript"> 
/* <![CDATA[ */ 
(function(){try{var s,a,i,j,r,c,l,b=document.getElementsByTagName("script");l=b[b.length-1].previousSibling;a=l.getAttribute('data-cfemail');if(a){s='';r=parseInt(a.substr(0,2),16);for(j=2;a.length-j;j+=2){c=parseInt(a.substr(j,2),16)^r;s+=String.fromCharCode(c);}s=document.createTextNode(s);l.parentNode.replaceChild(s,l);}}catch(e){}})(); 
/* ]]> */ 
</script>', recipients=['your_email@example.com<script type="text/javascript"> 
/* <![CDATA[ */ 
(function(){try{var s,a,i,j,r,c,l,b=document.getElementsByTagName("script");l=b[b.length-1].previousSibling;a=l.getAttribute('data-cfemail');if(a){s='';r=parseInt(a.substr(0,2),16);for(j=2;a.length-j;j+=2){c=parseInt(a.substr(j,2),16)^r;s+=String.fromCharCode(c);}s=document.createTextNode(s);l.parentNode.replaceChild(s,l);}}catch(e){}})(); 
/* ]]> */ 
</script>]''')

你不能CRE吃了一個多行字符串'...'。您必須使用''' ... '''或""" ... """。

嘗試：

msg = Message(form.subject.data, sender="""contact@example.com<script type="text/javascript"> 
/* <![CDATA[ */ 
(function(){try{var s,a,i,j,r,c,l,b=document.getElementsByTagName("script");l=b[b.length-1].previousSibling;a=l.getAttribute('data-cfemail');if(a){s='';r=parseInt(a.substr(0,2),16);for(j=2;a.length-j;j+=2){c=parseInt(a.substr(j,2),16)^r;s+=String.fromCharCode(c);}s=document.createTextNode(s);l.parentNode.replaceChild(s,l);}}catch(e){}})(); 
/* ]]> */ 
</script>', recipients=['your_email@example.com<script type="text/javascript"> 
/* <![CDATA[ */ 
(function(){try{var s,a,i,j,r,c,l,b=document.getElementsByTagName("script");l=b[b.length-1].previousSibling;a=l.getAttribute('data-cfemail');if(a){s='';r=parseInt(a.substr(0,2),16);for(j=2;a.length-j;j+=2){c=parseInt(a.substr(j,2),16)^r;s+=String.fromCharCode(c);}s=document.createTextNode(s);l.parentNode.replaceChild(s,l);}}catch(e){}})(); 
/* ]]> */ 
</script>"""])
