Question

我正在尝试使用Policy doument设置文件上传到Google云端存储。

参考：https://cloud.google.com/storage/docs/xml-api/post-object#policydocument

政策文件

{"expiration": "2020-06-16T11:11:11Z",
 "conditions": [
  ["starts-with", "$key", "" ],
  {"acl": "bucket-owner-read" },
  {"bucket": "cli201509.appspot.com"},
  {"success_action_redirect": "http://cli201509.appspot.com/getpolicydocumentsuccess" },
  ["eq", "$Content-Type", "image/jpeg" ],
  ["content-length-range", 0, 1000000]
  ]
}

HTML表格

<form action="http://storage.googleapis.com" method="post" enctype="multipart/form-data">

我已经查看了JSON，但我发现它格式不正确。

这是你正在使用的那个，

"{'expiration': '2020-06-16T11:11:11Z', 'conditions': [ ['starts-with', '$key', '' ], {'acl': 'bucket-owner-read' }, {'bucket': 'cli201509.appspot.com'}, {'success_action_redirect':'cli201509.appspot.com/getpolicydocumentsuccess'; }, ['eq', '$Content-Type', 'image/jpeg' ], ['content-length-range', 0, 1000000] ]}"

尽管如此，正确的版本应该将所有单个撇号替换为double（“而不是”）。

{
    "conditions": [
        ["starts-with", "$key", ""], {
            "acl": "bucket-owner-read"
        }, {
            "bucket": "cli201509.appspot.com"
        }, {
            "success_action_redirect": "http://cli201509.appspot.com/getpolicydocumentsuccess"
        },
        ["eq", "$Content-Type", "image/jpeg"],
        ["content-length-range", 0, 1000000]
    ],
    "expiration": "2020-06-16T11:11:11Z"
}

一旦我执行HTML表单，它就会给我一个错误的键错误，这意味着不平衡的语句已经解决了。你能证实它是否适合你吗？
