If you specify the `--raw` flag, you'll see 3 separate json objects, one in each row.

```nu
open urls.json | get urls | each { |u| http get $u -r }
# => ━━━┯━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
# =>  # │ <value>
# => ───┼─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
# =>  0 │ {
# =>    │   "userId": 1,
# =>    │   "id": 1,
# =>    │   "title": "sunt aut facere repellat provident occaecati excepturi optio reprehenderit",
# =>    │   "body": "quia et suscipit\nsuscipit recusandae consequuntur expedita et cum\nreprehenderit molestiae ut ut quas totam\nnostrum
# =>    │ rerum est autem sunt rem eveniet architecto"
# =>    │ }
# =>  1 │ {
# =>    │   "userId": 1,

# =>    │   "title": "ea molestias quasi exercitationem repellat qui ipsa sit aut",

# =>    │ }
# => ━━━┷━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

To combine these responses together into a valid JSON array, you can turn the table into json.

```nu
open urls.json | get urls | each { |u| http get $u } | to json
```

Output

```json
[
  {
    "userId": 1,
    "id": 1,
    "title": "sunt aut facere repellat provident occaecati excepturi optio reprehenderit",
    "body": "quia et suscipit\nsuscipit recusandae consequuntur expedita et cum\nreprehenderit molestiae ut ut quas totam\nnostrum rerum est autem sunt rem eveniet architecto"
  },
  {
    "userId": 1,
    "id": 2,
    "title": "qui est esse",
    "body": "est rerum tempore vitae\nsequi sint nihil reprehenderit dolor beatae ea dolores neque\nfugiat blanditiis voluptate porro vel nihil molestiae ut reiciendis\nqui aperiam non debitis possimus qui neque nisi nulla"
  },
  {
    "userId": 1,
    "id": 3,
    "title": "ea molestias quasi exercitationem repellat qui ipsa sit aut",
    "body": "et iusto sed quo iure\nvoluptatem occaecati omnis eligendi aut ad\nvoluptatem doloribus vel accusantium quis pariatur\nmolestiae porro eius odio et labore et velit aut"
  }
]
```

Making a `post` request to an endpoint with a JSON payload. To make long requests easier, you can organize your json payloads inside a file.

```json
{
  "my_payload": {
    "title": "foo",
    "body": "bar",
    "userId": 1
  }
}
```

```nu
open payload.json | get my_payload | to json | http post https://jsonplaceholder.typicode.com/posts $in
# => ━━━━━
# =>  id
# => ─────
# =>  101
# => ━━━━━
```

---

We can put this all together into a pipeline where we read data, manipulate it, and then send it back to the API. Lets `fetch` a post, `increment` the id, and `post` it back to the endpoint. In this particular example, the test endpoint gives back an arbitrary response which we can't actually mutate.

```nu
open urls.json | get urls | first | http get $in | upsert id {|item| $item.id | inc} | to json | http post https://jsonplaceholder.typicode.com/posts $in
# => ━━━━━
# =>  id
# => ─────
# =>  101
# => ━━━━━
```

### Uploading files

To upload a form with a file (think a common file upload form in a browser, where you have to select a file and provide some additional data), you need to:

1. Specify the content type as `multipart/form-data`
2. Provide the record as the POST body
3. Provide the file data in one of the record fields as *binary* data.
