I am converting my sqlite database to Couchdb. I can convert the db and upload to the Couchdb server. Everything but the images. I want to upload the images as standalone attachments and I would like to do this in bulk using javascript, REST, and xhr.

POST http://127.0.0.1:5984/database/_bulk_docs

Data : {"_id": "701", "_attachments": {"555_image.png": { "content_type": "image/jpg","data":[object TiFilesystemFile]      }}}

推荐答案

您应该能够调整您的单个文件，并执行如下操作:

You should be able to adjust your single file, and do something like the following:

POST http://127.0.0.1:5984/database/_bulk_docs

数据为:

{
  "docs": [
    {"_id": "701", "_attachments": {"555_image.png": { "content_type": "image/jpg","data":[object TiFilesystemFile] }},
    {"_id": "702", "_attachments": {"556_image.png": { "content_type": "image/jpg","data":[object TiFilesystemFile] }},
    {"_id": "703", "_attachments": {"557_image.png": { "content_type": "image/jpg","data":[object TiFilesystemFile] }},
  ]
}

但是，根据附件的数量和大小，您可能会遇到问题.简单地循环并一次执行一个可能会更好；或至少在合理大小的批次中.

However, depending on the number and size of attachments you might run into problems. It might be better to simply loop and do them one at a time; or at least in reasonably sized batches.
