CouchDB附件无法打开

Question

我从位于localhost:5984/categories/Jan 以下数据的文档开始 :

{
  "_id": "Jan",
  "_rev": "4-2c0b1c27daca6d2a3c375b0f879a8967",
  "name": "Jan",
}

我想将pdf上传到此文档,因此我提供以下curl命令:

curl -vX PUT 'http://localhost:5984/categories/Jan/example.pdf?rev=4-2c0b1c27daca6d2a3c375b0f879a8967' -d@example.pdf -H "ContentType: application/pdf"

我得到了这样的答复:

* Connected to localhost (127.0.0.1) port 5984 (#0)

{"ok":true,"id":"Jan","rev":"5-4ae0ca0bd54d63b9ac45e3e57785648d"}

在我看来,这是一个成功的上传.但是,当我访问网址时 localhost:5984/categories/Jan/example.pdf,有两个问题:

• 而不是在浏览器中打开,我被要求下载附件
• 当我下载并打开附件时,它说无法读取数据.

除了pdf之外,其他内容类型也会发生这种情况(我也尝试过使用png).谁能让我知道可能会出错？谢谢.

Answer 1

问题似乎是您在附件创建期间指定的ContentType标头。

正确的标头名称是Content-Type

卷曲命令应该是：

curl -vX PUT 'http://localhost:5984/categories/Jan/example.pdf?rev=4-2c0b1c27daca6d2a3c375b0f879a8967' -d@example.pdf -H "Content-Type: application/pdf"
