您好，您这边使用的iserver具体是什么版本呢（例如：11.1.1)，您测试一下以下情况：

1.直接在iserver页面发布直接该工作空间是否正常

2.如果iserver页面发布该工作空间也出现500报错，请尝试发布其他工作空间例如示例数据工作空间发布是否正常

Comments

直接在iserver页面发布工作空间是可以的，用的版本是supermap-iserver-11.1.0-linux-x64

您好，排查方向建议如下：

1.打印出python组件发送的post请求，

2.在iserver页面发布工作空间时查看网络请求，

3.对比二者请求报文差别

4.修正python组件请求的格式

经过检查，python组件请求的格式是正确的，但是仍然报错，是怎么回事呢

根据报错信息来看，getWorkspace方法中data类型为string，而PublishServiceParameter 所需参数类型为json，需要转为json再发送请求
