Python unicode 解码错误 SUD

Question

好的，所以我的脚本顶部有# -*- coding: utf-8 -*-，它可以从数据库中提取包含有趣字符（Ñ，Õ，é，-，-，'，...）的数据，并且将这些数据存储到变量中...但是我遇到了其他问题，请参阅我提取数据，组织它，然后将其转储到如下变量中：

title = product[1]

product[1] 来自我的数据库结果集

然后我像这样为Suds 加载它：

array_of_inventory_item_submit = ca_client_inventory.factory.create('ArrayOfInventoryItemSubmit')
for product in products:
    inventory_item_submit = ca_client_inventory.factory.create('InventoryItemSubmit')
    inventory_item_list = get_item_list(product)
    inventory_item_submit = [inventory_item_list]
    array_of_inventory_item_submit.InventoryItemSubmit.append(inventory_item_submit)
#Call that service baby!
ca_client_inventory.service.SynchInventoryItemList(accountID, array_of_inventory_item_submit)

其中get_item_list 将product[1] 设置为标题和（包括一大堆其他节点）：

inventory_item_submit.Title = title

所以在我调用包含 array_of_inventory_item_submit 的 ca_client_inventory.service.SynchInventoryItemList 之前一切都运行良好，其中包含带有时髦字符的标题...这是错误：

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 116: ordinal not in range(128)

现在呢？我的猜测是我的脚本可以接收这些时髦的字符，因为我在顶部有 # -*- coding: utf-8 -*-，但 Suds 的文件顶部没有它。我真的想去更改 Suds 文件吗...我们都知道这是最不希望的最后可能的解决方案...我该怎么办？

Answer 1

#-*- coding: xxx -*-与此错误无关，它只适用于声明它的源文件的编码，而不适用于来自数据库的变量内容。

您的错误表明您尝试将包含非 ASCII 字符的 str 类型对象传递给 unicode() 构造函数（在 line 43 of suds/sax/text.py 处调用）。

您必须将来自数据库的字符串转换为unicode 对象；例如，如果您的数据库以 UTF-8 编码：

title = product[1].decode("UTF-8")

有关详细信息，请参阅str.decode() 文档。
