我正在开发一个 Kivy 应用程序，需要使用 boto3 将文件上传到 S3但在 JSON decoder.py 中失败当尝试加载endpoint时模型并建立 client联系。这在本地运行于 16.04 上运行良好。但用 buildozer 编译后失败并在 Lollipop 5.1.1 上运行.
Buildozer 日志。

导致问题的连接命令是:
main.py
client = boto3.client(
's3',
aws_access_key_id='IVEGOTTHEKEY',
aws_secret_access_key='IVEGOTTHESECRET',
region_name='ap-southeast-2',
)
查看堆栈跟踪，它在尝试加载时失败了 endpoints.json与 botocore.loader在load_file load_data 中的行方法:
loaders.py
@instance_cache
def load_data(self, name):
for possible_path in self._potential_locations(name):
found = self.file_loader.load_file(possible_path)
if found is not None:
return found
# We didn't find anything that matched on any path.
raise DataNotFoundError(data_path=name)
这里正在寻找endpoints.json在 _potential_locations它们是:
loaders.py
# The included models in botocore/data/ that we ship with botocore.
BUILTIN_DATA_PATH = os.path.join(BOTOCORE_ROOT, 'data')
# For convenience we automatically add ~/.aws/models to the data path.
CUSTOMER_DATA_PATH = os.path.join(os.path.expanduser('~'),
'.aws', 'models')
BOTOCORE_ROOT是它应该获取这些文件的地方。部署到 Android 时 BOTOCORE_ROOT是 /data/data/com.phyto.phytogp/files/app/lib/python2.7/site-packages/botocore 。
endpoints.json存在于这条路径上。正在转移endpoints.json从平板电脑到 PC 并调用 load_file JSONFileLoader的方法工作正常并返回 OrderedDict没有解码失败。
堆栈跟踪没有显示它无法通过引发 DataNotFoundError 来找到文件。这表明它找到了该文件，但无法解析它，因此 json/decoder错误。

#
# You can extend section / key with a profile
# For example, you want to deploy a demo version of your application without
# HD content. You could first change the title to add "(demo)" in the name
# and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
# Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

我没有主意，所以任何帮助都会很棒。谢谢
最佳答案
经过几天的工作，没有找到解决异常 JSON 解析问题的方法。最后，回滚到 boto (v2)，它尚未实现确定端点等的 JSON 模型。部署时工作正常。
