例：

• 将指定节点(node0)加入为观察者节点

# 以将node0加入观察者节点为例: 
# 获取node0的NodeID
$ cat ~/fisco/nodes/127.0.0.1/node0/conf/node.nodeid

# 将node0加入为观察者节点
$ ./console.py  addObserver 2f0a2cfb4b2e5f63fda88c2bdb9edd8f8dd2a408c04c1d4fda8a75ad1047baf87c2b18f4dbf20d67db84019b221bf50b683eeebade7e5eaffefef876e5db9a8c
# 输出信息如下：

     >> addObserver succ, output: 1

• 再次将指定节点(node0)加入为观察者节点，期望返回提示信息“the node is already in the observer list”，可是仍然返回添加成功

# 将node0加入为观察者节点
$ ./console.py  addObserver 2f0a2cfb4b2e5f63fda88c2bdb9edd8f8dd2a408c04c1d4fda8a75ad1047baf87c2b18f4dbf20d67db84019b221bf50b683eeebade7e5eaffefef876e5db9a8c

需要在Python SDK中，对addObserver操作做防重：

• 通过getObserverList接口获取当前观察节点列表
• 将要添加的节点Node ID与获取的节点列表做对比，若已经在观察节点列表中，则返回提示信息the node is already in the observer list

发现带校验的amop，官方文档中只给了web3sdk的样例，请问python是否支持？

ubuntu20.04 Python 3.8.3 fisco 2.9

File "./console2.py", line 10
SyntaxError: Non-ASCII character '\xef' in file ./console2.py on line 11, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

但是我看文件头已经加了# -- coding: utf-8 --
不知道为什么报错？

使用crud_service创建table需要设置key，但是

1. 插入entry时并不检查key是否重复
2. 使用CRUDService.select()方法时，condition内必须含有对key的限制
3. 基于(2)，调用CRUDService.desc()方法时，会报错
   Must set condition for the primary key

执行RPC Query Cmds相关命令正常，但执行CONSENSUS cmd就会报错，示例命令: python3 console3.py addSealer 27582c8*** ,报错文件如下：
cpp_sdk_log_2023031416.09.log

希望SDK连接节点支持基于域名的TLS访问，我们就可以通过nginx的SNI转发访问，收拢所有节点的访问ip和端口

我根据TableTest.sol写了一个合约，只是把TableTest里的int256类型也换成了string类型，然后使用python SDK去进行合约调用，表现出以下行为：

• 调用select没有任何问题，能select到内容
• 调用insert能获得返回值，能返回count值1，也能返回输入参数
• 再次调用select，检索不到插入的内容，非常奇怪，因为上一步有返回值但就是无法select到
• 使用console的方式去同样调用insert
• 再次调用select，能检索到插入的内容
• 还是使用python sdk的方式去insert，不行

python 调用部分

例：
调用HelloWorld合约，返回的解析信息 ('Hello, World!',)包含多余的括号和逗号，建议去掉：

• 部署HelloWorld合约

$ ./console.py  deploy HelloWorld

获取到输出的合约地址是0x84139e0d46160aa2dd2541f499049095596891c9

• 调用HelloWorld合约的get接口：

$  ./console.py  call  HelloWorld  0x84139e0d46160aa2dd2541f499049095596891c9 get
# 输出如下：call result结果中，包含多余的括号和逗号，需要将元组转换成字符串输出
INFO >> user input : ['call', 'HelloWorld', '0x84139e0d46160aa2dd2541f499049095596891c9', 'get']

INFO >> call HelloWorld , address: 0x84139e0d46160aa2dd2541f499049095596891c9, func: get, args:[]
INFO >> call result: ('Hello, World!',)

建议将call result后直接输出的元组转换为字符串输出。

向游离状态的节点发起请求，展示返回信息包含反斜杠包含""不友好，需要优化：

例：

• python SDK直连的节点做退网操作

# 获取直连节点Node ID(搭链操作参考FISCO-BCOS文档：https://fisco-bcos-documentation.readthedocs.io/zh_CN/latest/docs/installation.html)
$ cat ~/fisco/nodes/127.0.0.1/node0/conf/node.nodeid
2f0a2cfb4b2e5f63fda88c2bdb9edd8f8dd2a408c04c1d4fda8a75ad1047baf87c2b18f4dbf20d67db84019b221bf50b683eeebade7e5eaffefef876e5db9a8c

# 调用removeNode进行退网操作
$ ./console.py removeNode 2f0a2cfb4b2e5f63fda88c2bdb9edd8f8dd2a408c04c1d4fda8a75ad1047baf87c2b18f4dbf20d67db84019b221bf50b683eeebade7e5eaffefef876e5db9a8c

• 向已经退网的节点发送交易（如getSealerList）

$ ./console.py  getSealerList 
# 输出信息如下：error_infomation中含有反斜杠

INFO >> user input : ['getSealerList']

ERROR >> execute getSealerList failed
ERROR >> error information: init bcosclient failed, reason: (-1, None, 'getBlockNumber failed, params: [1], response: {\'result\': {\'error\': {\'code\': -40009, \'data\': None, \'message\': "Don\'t send request to this node who doesn\'t belong to the group"}, \'id\': 0, \'jsonrpc\': \'2.0\'}}, error information: (-40009, None, "Don\'t send request to this node who doesn\'t belong to the group")')

建议处理以上json信息中的反斜杠

下载安装之前的Python SDK（不是新推出的 Dev220209 版本），用python sdk自带控制台操作，

1. 部署 HelloWorld 合约，正常。
2. ./console.py call HelloWorld address get
   Fisco 节点能正常返回结果，但是Client端无法正确解析，结果如下。

$ python3 ./console.py call HelloWorld 0x83592a3cf1af302612756b8687c8dc7935c0ad1d get

以上例外输出本人新增于 bcosclient.py 中BcosClient类的方法 call(...)中
错误发生于下面语句：
decoderesult = decode_abi(fn_output_types,decode_hex(outputdata))
即 decode_abi() 调用出错，没能正常解析出返回的结果，只是解析出了返回结果的几个 keys，而没有正确解析出 Values。

3. ./console.py sendtx HelloWorld address set "some string."
   Client 就不能正确编码输入的参数以提交给Fisco 节点，以上操作无法调用合约中的set(...)函数以更新字符串。
   命令执行的终端输出如下：
   $ python3 ./console.py sendtx HelloWorld last set "some string."

INFO >> user input : ['sendtx', 'HelloWorld', 'last', 'set', 'some string.']

到现在新推出的 python sdk （2022年9月），还只是支持 solc-0.4.25 (当然我不清楚这个版本是如何对应的)，下面一些常用的函数或表达式都不能支持。
string.concat(...)
type(uint).min, type(uint).max

demo_transaction里有这样一个示例：
receipt = client.sendRawTransactionGetReceipt(to_address, contract_abi, "set", args)
receipt里可以看到from地址的信息，但之前并没有指定过from地址，如果要显式指定from地址该如何操作？

但实际上目录只存在文件.keystore，不存在.pem

parsimonious库和SDK里的parsimonious有冲突。在SDK目录外调用时，结果解析会报错。

在使用过程会出现如下错误，可以怎么解决

The smart contract has a function
function _checkOwner() internal view virtual {
require(owner() == _msgSender(), "Ownable: caller is not the owner");
}

I expect the SDK to return an error "caller is not the owner" if user != owner, but If there was an error in the smart contract, it is not returned.
abi_parser.parse_output(fn_name, output) function returns empty result.
status in transaction = 16 - RevertInstruction.

How can I read an error from a smart contract?

如题.
谢谢.
还想请问.
python sdk之后会继续开发吗, 我们在做技术选型. 希望能找一个稳定的框架.
谢谢~

我是bicos3版本，成功部署了contracts文件夹下的KVTableTest合约，但是调用sendRawTransaction失败。
代码如下：
receipt = client.sendRawTransaction(
to_address,
contract_abi,
"set",
['aa', 11, 'haha']
)
返回的recipt如下：

请问是哪里有问题，急

不支持True和False写法，只能在abi文件手动改成ture 和false才可以生成模版。

智能合约里面有一个emit方法，作用是抛出一个事件，但是在文档和demo中，我都只看到可以从调用合约的返回值里获取log从而看到事件，找不到如何监听这个event的方法。所以这个有没有提供监听的途径呢？或者说我有没有办法通过一个for循环来轮询获得这个log呢？

client/local_lib_helper.py第38行
应该是aarch64,没有arch这个版本

问题描述：win10系统，参考文档进行安装，python版本3.10.5，fisco版本2.9.2

问题1：python-sdk没有console.py文件，我理解是console2.py对应的fisco 2版本，相应的配置我都配置了，包括solc，sdk证书

问题2：执行.console2.py getNodeVersion 报错

TransactionCommon.format_args_by_abi 这个方法参数序列化不支持数组和动态类型

请问call函数返回值是不是有长度要求，我在预编译合约中返回了很长的字符串，用call调用合约时报预编译错误（precomiled error），但是我将我返回的字符串减半后正常运行，不报错；请问这个限制怎么改

Python SDK工具，调用HelloWorld合约，返回的信息中包含一个逗号，建议优化
