Question

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

{
  "_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"

我收到了这个回复：

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

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：

我没有在浏览器中打开，而是要求下载附件
当我下载并打开附件时，表示无法读取数据。

除了pdfs之外，其他内容类型也会发生这种情况（我还尝试过使用png）。谁能让我知道可能会出错？感谢。

Answer 1

问题似乎是您在附件创建期间指定的 ContentType 标头。

正确的标题名称为内容类型

curl命令应为：

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

CouchDB附件无法打开
