对于（int i=0；i日志显示请求ARN无效
。这是因为COGNITO\u ROLE\u UNAUTH
是一个空字符串。请从IAM获取角色ARN，或从控制台复制示例代码
然后您会看到未授权执行sts:AssumeRoleWithWebIdentity
异常。当凭据提供程序请求sts承担您为会话凭据指定的角色，但您的角色未设置为信任Cognito时，会发生这种情况
从其名称判断，该角色是由您创建的，而不是由Cognito在控制台中生成的。我相信您忘记了信任关系。转到IAM控制台，编辑该角色，向下滚动，然后单击“编辑信任关系”。确保您具有以下内容（用您的Cognito标识池id替换池id）
{
“版本”：“2012-10-17”，
“声明”：[
{
“Sid”：“，
“效果”：“允许”，
“委托人”：{
“联邦”：“cognito identity.amazonaws.com”
},
“行动”：“sts:假定身份”，
“条件”：{
“StringEquals”：{
cognito identity.amazonaws.com:aud:“us-east-1:
},
“ForAnyValue:StringLike”：{
“cognito identity.amazonaws.com:amr:“未经验证”

您好，谢谢您的评论。我尝试为COGNIT O_ROLE_UNAUTH字符串添加值，警告日志现在已更改为授权问题。我不确定是否需要输入“IAM用户ARN”值或“角色ARN”值。我尝试了这两种方法。但不确定我是否输入了正确的值。请在此提供帮助。谢谢。此身份验证错误是由于Bucket策略造成的吗？您是否启用了对身份池的未授权访问？在创建身份池时，默认情况下会禁用此功能。请在AWS控制台中检查您的身份池设置。谢谢Yangfan，“启用对未经身份验证的身份的访问”框已签入（可在编辑身份池->未经身份验证的身份设置中找到），问题仍然存在。您是否检查了角色的信任关系？请参阅我的答复。
