latin-1 codec cant encode characters in position 42-48: ordinal not in range256 下載文件時候報錯

 

python後端寫下載文件，　這個時候出現了這個錯誤

latin-1 codec cant encode characters in position 42-48: ordinal not in range256

怎麼辦：

查原由：　發現文件名有中文名字，　因此致使錯誤，　編碼是latin-1編碼， 因此咱們須要解碼成unicode在編碼成latin-1

先看代碼：

　　這段代碼涉及python轉碼問題， 必定要注意

                FilePathName = self.get_argument("FilePathName", None) #獲取文件名
                FileName = str(FilePathName.split("/")[-1]).strip()　＃　獲得文件名
                latinFileName = FileName.encode("utf-8").decode("latin1") # 這句很關鍵， 要解析成latin-1才OK，這樣就不會報錯

 

class DownFileHandler(downBaseRequestHandler):
    @tornado.gen.coroutine
    def get(self, *args, **kwargs):

        if self.verifyFlag == 1 and self.status == 0:
            status = 2000

            try:
                FilePathName = self.get_argument("FilePathName", None)
                FilePathName = MyBase64.decryption(unquote(FilePathName)) # 這句是解密
                FileName = str(FilePathName.split("/")[-1]).strip()
                latinFileName = FileName.encode("utf-8").decode("latin1") # 這句很關鍵， 要解析成latin-1才OK，這樣就不會報錯
                newFileName = str(int(time.time())) + "." + FileName.split(".")[1] # 第二種方式就是換一個文件名
                self.set_header("Content-Type", "application/x-zip-compressed")
                # -----<或者這麼寫> ----- #
                # self.set_header("Content-Type", "application/octet-stream")
                self.set_header("Content-Disposition", "attachment; filename=%s" % latinFileName)
                f = open(FilePathName, 'rb')
                while True:
                    b = f.read(8096)

                self.flush()
                f.close()

            except Exception as e:
                e = FormatErrorCode(e)
                my_log.error(e)
                status = int(e[0])
                self.write(json.dumps(result(status=status)))
            self.finish()
        else:
