An example:
|
|
|
|
{{< code file="base64-input.html" >}}
|
|
<p>Hello world = {{ "Hello world" | base64Encode }}</p>
|
|
<p>SGVsbG8gd29ybGQ = {{ "SGVsbG8gd29ybGQ=" | base64Decode }}</p>
|
|
{{< /code >}}
|
|
|
|
{{< output file="base-64-output.html" >}}
|
|
<p>Hello world = SGVsbG8gd29ybGQ=</p>
|
|
<p>SGVsbG8gd29ybGQ = Hello world</p>
|
|
{{< /output >}}
|
|
|
|
You can also pass other data types as arguments to the template function which tries to convert them. The following will convert *42* from an integer to a string because both `base64Encode` and `base64Decode` always return a string.
|
|
|
|
```
|
|
{{ 42 | base64Encode | base64Decode }}
|
|
=> "42" rather than 42
|
|
```
|
|
|
|
## `base64` with APIs
|
|
|
|
Using base64 to decode and encode becomes really powerful if we have to handle
|
|
responses from APIs.
|
|
|
|
```
|
|
{{ $resp := getJSON "https://api.github.com/repos/gohugoio/hugo/readme" }}
|
|
{{ $resp.content | base64Decode | markdownify }}
|
|
```
|
|
|
|
The response of the GitHub API contains the base64-encoded version of the [README.md](https://github.com/gohugoio/hugo/blob/master/README.md) in the Hugo repository. Now we can decode it and parse the Markdown. The final output will look similar to the rendered version on GitHub.
