以下是如何使用AWS S3存储桶策略强制执行文件类型上载

应用存储桶策略时:

{
  "Version":"2008-10-17",
  "Statement": [
    {
      "Sid":"AddPerm",
      "Effect":"Allow",
      "Principal": { "AWS": "arn:aws:iam::111122223333:group/admins" },
      "Action": "s3:PutObject",
      "Resource": "arn:aws:s3:::bucket/*.txt"
    }
  ]
}

组"管理员"肯定存在,但我得到错误:"策略中的无效主体 - "AWS":"arn:aws:iam :: 111122223333:group/admins""

为什么不被认可？

在由以下代码生成的图中,我想改变颜色,使得所有值<0.6与"低"颜色相同,并且所有大于1的值都是"高"颜色.

按原样,颜色梯度在数据的整个数值范围内延伸.我已经尝试添加限制但是这使得所有越界值都与NA值相同,这不是我想要的,因为我需要缺少NA值以明确地伸出并且看起来不同于超出边界值<0.6的相同颜色.

我确信答案是关于oob,打破了争论,但没有成功让它发挥作用.

library(ggplot2)
a = rnorm(17*17, 0.733,0.21)
qcMat = matrix(a, ncol = 17)
qcMat[qcMat> 1] = 1
#qcMat contains values between 0 and 1 and some NAs

m = melt(t(qcMat))
m$Var2 <- with(m,factor(Var2, levels = rev(sort(unique(Var2)))))
ggplot(m, aes(as.factor(Var1), Var2, group=Var2)) +
  geom_tile(aes(fill = value)) +
  geom_text(aes(fill = m$value, label = round(m$value, 2))) +
  scale_fill_gradient(low = "red", high = "green") +
  xlab("") + ylab("") + ggtitle(paste("biscuit:", biscuit_id, "- QC", sep = " "))
