在 bash 脚本中，我将前一个命令的 URL 存储在 bash 变量$DESTINATION_URL中。我想使用这个变量运行 curl 命令。

如果我使用该$DESTINATION_URL变量，curl 命令将失败。

如果我对 URL 本身尝试相同的 curl 命令，它可以正常工作。似乎&是引起了问题，但我不明白为什么。

下面的例子：

ha@hadoop-fullslot1:~$ echo $DESTINATION_URL
http://hadoop-fullslot1:50075/webhdfs/v1/user/ha/s3distcp.jar?op=CREATE&user.name=hdfs&namenoderpcaddress=hadoop-meta1:8020&overwrite=true


ha@hadoop-fullslot1:~$ curl -v -s -i -X PUT -T $SOURCE "$DESTINATION_URL"

您的变量包含比 URL 更多的内容（垃圾）。我会猜测一个 CR 字节或其他东西，看看“HTTP/1.1”是如何首先打印在行上的，尽管它应该在 URL 的右侧......
