Question

我正在编写一个小程序，它是一个http服务器，可以列出目录中的每个文件，并使其可在浏览器中预览。当前，它可以列出所有文件和目录，并使它们可导航和预览文本文件。我正在尝试添加jpeg预览功能，但是img元素似乎无法通过其路径找到图像，即使我仍然可以通过单击它们来下载它们。

这是我第一次这样做，所以可能会有很多错误，所以请不要对我太苛刻。无论如何，这是相关代码：

def getDir(path:str):
    f = open(".\\_INTERNAL\\pageTemplate.html","rt")
    basePage = f.read()
    basePage = basePage.replace("${path}", path.replace("\_CONTENT","").replace("\\","/"))
    fileList =""
    pathUp = findParentPath(path)
    print(pathUp)
    print(path)
    if(pathUp != ".\\_CONTENT\\"):
        fileList +="<a href='{}'>..</a>".format(pathUp.replace(".\_CONTENT","")[:-1])
    for name in os.listdir(path):
        char = ''
        print(path[-1])
        if path[-1] != '/':
            char = '\\'
        if("." not in name):
            fileList +="<a class='folder-link' style='display:block' href='{1}'>{0}</a>".format(name, path.replace(".\_CONTENT","")+char+name)
        else:
            fileList +="<a class='file-link' style='display:block' href='{1}'>{0}</a>".format(name, path.replace(".\_CONTENT","")+char+name)
            if(name.split('.')[-1] == 'jpg'):
                fileList+="<img alt='{0}' src='{1}' style='display:block'>".format(name, path.replace(".\_CONTENT","")+char+name)
    return basePage.replace("${filelist}", fileList)

    request = sock.recv(4096).decode()
        print(request)
        file_to_send = request[request.find("GET /") + len("GET /"):]
        file_to_send = file_to_send[:file_to_send.find(" ")]

        if file_to_send == "":
            file_to_send = "index.html"

        file_to_send = file_to_send.replace("%20", " ")
        contentType = "*/*"
        if os.path.exists(".\\_CONTENT\\" + file_to_send):
            if(os.path.isdir(".\\_CONTENT\\" + file_to_send)):
                data = getDir(".\\_CONTENT\\" + file_to_send).encode()
            else:
                if(file_to_send.split('.')[-1] == 'txt'):
                    data = getTxtFile(".\\_CONTENT\\" + file_to_send).encode()
                else:
                    if(file_to_send.split('.')[-1] == 'jpeg' or 'jpg'):
                        contentType = 'image/jpeg'
                    f = open(".\\_CONTENT\\" + file_to_send,"rb")
                    data = bytes(f.read())
        else:
            f = open(".\\_INTERNAL\\404.html","rb")
            data = bytes(f.read())
        headers = """
HTTP/1.1 200 OK
Content-Length: """ + str(len(data)) +"\nContent-Type: "+contentType+ """ 
Connection: Closed
        """
        print(headers)
        sock.send((headers + "\n\n").encode() + data)
        sock.close()

通过http服务器发送时图像不显示
