尝试通过 API 将成员添加到 Google 群组时出现“缺少必填字段：成员”

尝试使用 Google 管理目录 API 来读取 google 群组（组织）的成员 - 它工作正常。当我尝试添加成员时，我得到：

{ errors: 
   [ { domain: 'global',
       reason: 'required',
       message: 'Missing required field: member' } ],
  code: 400,
  message: 'Missing required field: member' }

我用谷歌搜索了错误并发现了类似的问题this https://stackoverflow.com/questions/22765599/missing-required-field-member, this https://stackoverflow.com/questions/27057265/google-groups-directory-api-add-user-to-group-raises-error-php以及其他一些无用的结果。

我查了一下，确实是not缺少范围或权限。

Comment:
我通过使用sdk成功实现了我想要的apiclient.discovery.build，但仍然 - 我很好奇，问题是什么以及是否可以解决。

调试请求：

由于 google API 使用（仅？）JSON 编码，因此您的帖子数据不会被解析为所需的成员对象。您已经加载了响应的 json，因此您只需要更改编码，并可以选择显式指示它：

 if payload:
        (resp, content) = http.request(uri=url, method=method, body=urlencode(payload))
 # becomes:   
 if payload:
        (resp, content) = http.request(uri=url, method=method, body=json.dumps(payload), headers={'Content-type':'application/json'})
