无法打开 CouchDB 附件

Question

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

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

我想上传一个pdf到这个文件，所以我给出了下面的curl命令：

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

我收到了这样的回复：

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

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

在我看来这是一次成功的上传。但是，当我访问 url localhost:5984/categories/Jan/example.pdf，有两个问题：

我没有在浏览器中打开，而是要求我下载附件
下载后打开附件，提示无法读取数据

除 pdf 之外的其他内容类型也会发生这种情况（我也尝试过使用 png）。任何人都可以让我知道可能出了什么问题吗？谢谢。

Answer 1

问题似乎是您在创建附件时指定的 ContentType header。

正确的header名字是Content-Type

curl 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"
