pycurl：用正确测试编码的filepath崩溃（错误26，＆＃x27;＆＃x27;）发帖。

Question

我的Pycurl版本7.45.1有问题，Windows 10上的Python 3.10.4。

我想从计算机上将文件发布到API上。当我运行代码时（可能），Filepath会出现问题，因为我以我的名义以及在完整的Filepath中有一个讨厌的“ Umlauts”。

我的上传文件的filepath可能看起来像：“ c：\\ users \\namewith_ö\\ folder \\ folder \\ enother_folder \\ more_folders \\ more_folders \\ file.pdf”

我已经找到了一些答案ASCII字符或字节词，因此我事先将FilePath字符串编码为UTF-8，这似乎也起作用，因为我在curl.setopt（curl.httpppost，files，files，files），的呼叫上获得了UnicodeencodeError。现在，使用编码的filepath，我收到错误消息“错误（26，''）”。

这是卷曲调用的代码：

def post(self, request_url, custom_headers : list = None, upload_fields : dict = None, upload_files : dict = None, further_directives : dict = None, proxy : dict = None):
        """
        Posts a HTTP POST request and returns a response object.

        :param request_url: The URL that request should point to.
        :type request_url: string
        :param custom_headers: An optional list of costum headers that should be sent with the request.
        :type custom_headers: list
        :param upload_fields: An optional dict of data that should be inputted into targeted upload fields {key = field name: value = input data}.
        :type upload_fields: dict
        :param upload_files: An optional dict of files that should be uploaded to the target site {key = field name: value = dict {key = 'filepath': value = path to file (required), key = 'new_filename': value = new name for uploaded file (optional), key = 'content_type': value = content type (optional, default is 'multipart/form-data')}}.
        :type upload_files: dict
        :param further_directives: An optional dict of further directives that should be included in the request (for list of all possible directives see PLACEHOLDER).
        :type further_directives: dict
        :param proxy: An optional dict of information used to route the request through a proxy {key = proxy port: value = int, key = proxy domain: value = string}
        :type proxy: dict

        :returns: Response object.
        :rtype: Curlified_Response
        """

        self.prepare_new_request()

        body_buffer = BytesIO()
        curl = pycurl.Curl()

        request_url, custom_headers, further_directives, proxy, upload_fields, upload_files = self.encode_strings(request_url, custom_headers, further_directives, proxy, upload_fields, upload_files)

        curl.setopt(curl.URL, request_url)
        if proxy:
            self.inject_kerberos_proxy(proxy['proxy port'], proxy['proxy domain'], curl)#
        if custom_headers:
            curl.setopt(curl.HTTPHEADER, custom_headers)#
        if further_directives:
            for item in further_directives.items():
                self.include_further_directive(item, curl)#
        if upload_fields:
            postfields = urlencode(upload_fields)#
            curl.setopt(curl.POSTFIELDS, postfields)
        if upload_files:
            files = []
            for item in upload_files.items():
                files.append(self.build_file_upload(item, curl))#
            curl.setopt(curl.HTTPPOST, files)
        curl.setopt(curl.HEADERFUNCTION, self.read_header_line)
        curl.setopt(curl.WRITEFUNCTION, body_buffer.write)
        curl.perform()
        self.read_body(body_buffer)
        curl.close()

这是用于参考的方法build> build_file_upload：

def build_file_upload(self, item, curl):
        """
        Gets a tuple of information for a file upload, checks the correctnes of the content and returns the properly built input.
        """

        info_list = []
        for i in item[1].items():
            if i[0] == 'filepath':
                info_list.append(curl.FORM_FILE)
                info_list.append(i[1])
            elif i[0] == 'new filename':
                info_list.append(curl.FORM_FILENAME)
                info_list.append(i[1])
            elif i[0] == 'contenttype':
                info_list.append(curl.FORM_CONTENTTYPE)
                info_list.append(i[1])
            else:
                raise ArgumentsError("No known file upload key was provided! Please revise.")
        if not info_list:
            raise RequiredArgumentsMissing("One or more required parameters for the file to be uploaded are missing! Please revise.")
        if 'content_type' not in info_list:
            info_list.append(curl.FORM_CONTENTTYPE)
            info_list.append(b'multipart/form-data')
        return (item[0], tuple(info_list))

最后，这是将给定字符串编码为字节的方法encode_strings：

def encode_strings(self, request_url, custom_headers, further_directives, proxy, upload_fields = None, upload_files = None):
        """
        Turns all given strings into bytes to be processable by PycURL.
        """

        custom_headers = [] if custom_headers is None else custom_headers
        upload_fields = {} if upload_fields is None else upload_fields
        upload_files = {} if upload_files is None else upload_files
        further_directives = {} if further_directives is None else further_directives
        proxy = {} if proxy is None else proxy

        request_url = bytes(request_url, 'UTF-8')
        for i in range(len(custom_headers)):
            if isinstance(custom_headers[i], str):
                custom_headers[i] = bytes(custom_headers[i], 'UTF-8')
        for k, v in further_directives.items():
            if isinstance(v, str):
                further_directives[k] = bytes(further_directives[k], 'UTF-8')
        for k, v in proxy.items():
            if isinstance(v, str):
                proxy[k] = bytes(proxy[k], 'UTF-8')
        for k, v in upload_fields.items():
            if isinstance(v, str):
                upload_fields[k] = bytes(upload_fields[k], 'UTF-8')
        for k, v in upload_files.items():
            if isinstance(v, dict):
                for key, value in v.items():
                    if isinstance(value, str):
                        upload_files[k][key] = bytes(upload_files[k][key], 'UTF-8')
        
        if len(upload_fields) == 0 and len(upload_files) == 0:
            return request_url, custom_headers, further_directives, proxy
        else:
            return request_url, custom_headers, further_directives, proxy, upload_fields, upload_files

i希望任何人都知道问题可能是什么，甚至可以解决这个问题，真的失去了我的大理石。
