Question

我正在尝试通过POST请求将一个320个字符的文本帖子发送到/路由。在那条路线上，我有一个类似于Twitter的社交网站，用于发布帖子和关注用户。要创建和编写帖子，我希望它是异步的，我的意思是，我希望用户编写一个帖子，当他按下按钮将其发布时，不应重新加载页面。

这是我的html文件：

<div class="container">
  <h1>All Posts</h1>
    <div class="row">
        <div class="span12 well">
            <form method="post">
              {% csrf_token %}
                <textarea class="span11" id="new_message" name="new_message"
                placeholder="Write something nice" rows="5"></textarea>
                <h6 id="characters">320 characters remaining</h6>
                <button class="btn btn-info" type="submit">Post New Message</button>
            </form>
        </div>
    </div>
</div>

这是我要在JavaScript中尝试做的事情，但我得到了403：

document.querySelector("form").onsubmit = () => {
    //sending values by POST method
  fetch('/', {
    method: 'POST',
    body: JSON.stringify({
      content: document.querySelector('#new_message').value,
    })
  })
  .then(response => response.json())
  .then(result => {

      // Print result
      console.log(result);
    })

  event.preventDefault()
  }


});

我也不太确定这是否是正确的方法。

后端：

def index(request):
    if request.method == "POST":
        content = request.POST["new_message"]
        print(request.user)
        print(content)
        return render(request, "network/index.html")
        #post = Posts(user=request.user, content=content)
    return render(request, "network/index.html")


def login_view(request):
    if request.method == "POST":

        # Attempt to sign user in
        username = request.POST["username"]
        password = request.POST["password"]
        user = authenticate(request, username=username, password=password)

        # Check if authentication successful
        if user is not None:
            login(request, user)
            return HttpResponseRedirect(reverse("index"))
        else:
            return render(request, "network/login.html", {
                "message": "Invalid username and/or password."
            })
    else:
        return render(request, "network/login.html")


def logout_view(request):
    logout(request)
    return HttpResponseRedirect(reverse("index"))


def register(request):
    if request.method == "POST":
        username = request.POST["username"]
        email = request.POST["email"]

        # Ensure password matches confirmation
        password = request.POST["password"]
        confirmation = request.POST["confirmation"]
        if password != confirmation:
            return render(request, "network/register.html", {
                "message": "Passwords must match."
            })

        # Attempt to create new user
        try:
            user = User.objects.create_user(username, email, password)
            user.save()
        except IntegrityError:
            return render(request, "network/register.html", {
                "message": "Username already taken."
            })
        login(request, user)
        return HttpResponseRedirect(reverse("index"))
    else:
        return render(request, "network/register.html")

因为403表示禁止，所以我将尝试检查您尝试调用的实体的权限。确保正确的文件具有正确级别的执行权限。通过您使用的apache或其他类型的Web服务器检查错误日志，访问日志可能会在其中找到某些内容。另外，在您的JS中，您正在向控制台记录一些内容，JS将什么推送到控制台？

对“ /”的POST请求返回403禁止
