Question

我仅出于学习目的制作网站。当我尝试使用发布请求时，它显示了以下错误：

/ analyse处的RuntimeError

您通过POST调用了此URL，但该URL并非以斜杠结尾，并且已设置APPEND_SLASH。 Django在维护POST数据时无法重定向到斜杠URL。更改表单，使其指向127.0.0.1:8000/analyse/（请注意斜杠），或在Django设置中设置APPEND_SLASH = False。

这是我的views.py和index.html：

views.py：

参考djtext = request.post.get('text', 'default')

# I have created this file - Piyush
from django.http import HttpResponse
from django.shortcuts import render


def index(request):
return render(request, 'index.html')

# return HttpResponse("Home")


def analyse(request):
global line
djtext = request.POST.get('text', 'default')
print(djtext)

# Check checkbox value
removepunc = request.GET.get('removepunc', 'off')
fullcaps = request.GET.get('fullcaps', 'off')
newlineremover = request.GET.get('newlineremover', 'off')
extraspaceremover = request.GET.get('extraspaceremover', 'off')


    # Check which checkbox is on
    if removepunc == "on":

    punctuations = '''!()-{}[]:;'",<>./?@#$%^&*_~'''
    analysed = ""
    for char in djtext:
        if char not in punctuations:
            analysed = analysed + char

    params = {'purpose': 'Removed punctuations', 'analysed_text': analysed}
    return render(request, 'analyse.html', params)
    elif fullcaps == "on":
    analysed = ""
    for char in djtext:
        analysed = analysed + char.upper()

    params = {'purpose': 'Change to UPPERCASE', 'analysed_text': analysed}
    return render(request, 'analyse.html', params)

    elif newlineremover == "on":
    analysed = ""
    for char in djtext:
        if char != "\n":
            analysed = analysed + char

    params = {'purpose': 'Removed new Lines', 'analysed_text': analysed}
    return render(request, 'analyse.html', params)

    elif extraspaceremover == "on":
    analysed = ""
    for index, char in enumerate(djtext):
        if djtext[index] == " " and djtext[index + 1] == " ":
            pass
        else:
            analysed = analysed + char
    params = {'purpose': 'Remove extra space', 'analysed_text': analysed}
    return render(request, 'analyse.html', params)

    else:
    return HttpResponse("Error")

Answer 1

请确保在您发送任何请求时都紧跟/。 Django会将您重定向到正确的位置（带斜线或不带斜线），但POST数据会被删除。
