在这里插入图片描述

定义文件上传函数

#文件上页面
def uploadFileIndex(request):
    return render(request, "uploadFile.html")

#文件上传接口
def uploadFile(request):
    if request.method == 'POST' and request.FILES['file']:
        uploaded_file = request.FILES['file']
        fs = FileSystemStorage()

        # 选择要保存文件的目录，例如 "media/uploads/"
        # 请确保该目录在Django的设置中已正确配置
        save_path = "./upload/"
        # 检查目录是否存在，如果不存在，则创建它
        if not os.path.exists(save_path):
            os.makedirs(save_path)
        # 将文件保存到指定目录
        filename = fs.save(os.path.join(save_path, uploaded_file.name), uploaded_file)

        # 获取保存后的文件URL
        file_url = fs.url(filename)

        # 打印文件保存路径和URL
        print("文件已保存到：", filename)
        print("文件URL：", file_url)

        return render(request, "success.html", {"msg": "上传成功", "file_url": file_url})
    return render(request, "error.html", {"msg": "上传失败"})

定义文件上传HTML界面

<!DOCTYPE html>

<head>
    <meta charset="UTF-8">

            padding: 0;
            display: flex;
            justify-content: center;
            align-items: center;
            min-height: 100vh;
        }

        .container {
            background-color: #fff;
            border-radius: 10px;
            box-shadow: 0 4px 6px rgba(0, 0, 0, 0.1);
            width: 400px;
            padding: 30px;
            text-align: center;
        }

        h1 {
            color: #3498db;
        }

        label {
            display: block;
            font-weight: bold;
            margin-top: 20px;
        }

        input[type="file"] {
            width: 100%;
            padding: 10px;
            border: 1px solid #ccc;
            border-radius: 5px;
        }

        input[type="submit"] {

            color: #fff;
            padding: 10px 20px;
            border: none;
            border-radius: 5px;
            cursor: pointer;
        }

        .fa-cloud-upload-alt {
            font-size: 48px;
            color: #3498db;
        }
    </style>
</head>
<body>
    <div class="container">
        <h1>文件上传 <i class="fas fa-cloud-upload-alt"></i></h1>
        <form action="/uploadFile" method="post" enctype="multipart/form-data">
            {% csrf_token %}
