Question

我正在使用IBM云功能的两个操作-write1和write2（均使用PYTHON）。

我创建了一个序列，该序列应将值从write1传递到write2。

我在write1动作中编写了PYTHON代码，但抛出了一些 JSON错误。

写入1个Python文件：*

    import os
    import sys
    import json
    import requests
    import ibm_boto3
    from ibm_botocore.client import Config, ClientError

    cos = ibm_boto3.resource("s3",
          ibm_api_key_id='my-api-key',
          ibm_service_instance_id='my-instance-id',
          config=Config(signature_version="oauth"),
         endpoint_url='https://s3.eu-gb.cloud-object-storage.appdomain.cloud'
         )

    def get_item(bucket_name, item_name):
      a={"Retrieving item from bucket":bucket_name , "key": item_name}
      print(json.dumps(a))
    try:
        file = cos.Object(bucket_name, item_name).get()
        return file["Body"].read()
    except ClientError as be:
        w={"CLIENT ERROR":be}
        print(json.dumps(w))
    except Exception as e:
        y={"Unable to retrieve file contents":e}
        print(json.dumps(y))


    def test():
      x = get_item('cloud-college-bucket0','abc.txt') 
      print(x.decode('utf-8'))

    if x is not None:
        string_in_uppercase = x.upper();
        n={"String in Uppercase =":string_in_uppercase.decode('utf-8')}
        b=json.dumps(n)
        print(b)

    def main(dict):
      return test()      

    if __name__ == '__main__':
      main()

引发的错误：

结果：

{
  "error": "**The action did not produce a valid JSON response**: null\n"
}

它说import request是我做的，但问题仍然存在。

我也说过使用request.post函数，但是如何使用和在哪里使用是我无法理解的。 以及如何解决此JSON问题？

所需的输出显示在日志中。

Answer 1

从一开始，我就可以看到test函数仅显示JSON，但从不返回。但是，如果您看到示例Python动作，则它始终应返回JSON

import sys

def main(dict):
    return { 'message': 'Hello world' }

此外，您可以在执行操作之前使用Python运行时here查看受支持的软件包列表。

如果您的软件包不在列表中，则可以始终package Python code with a virtual environment in .zip files或Packaging code in Docker images

该操作未在python文件中产生有效的JSON对象
