XML Body
To get started, change your method to POST, PUT or PATCH depending on the requirements of the API. After that, you will need to add the HasBody
interface to your request. Without this interface, Saloon will not send any request body to the HTTP client.
Next, you will need to add the HasXmlBody
trait to your request. This trait will implement the body()
method that the HasBody
interface requires. It also provides a method defaultBody()
which you can extend to provide a default body on your request.
Saloon will automatically send the Content-Type: application/xml
header for you when using the HasXmlBody
trait, however, if you would like to overwrite this behaviour then you can use the defaultHeaders
method on the request or modify the headers before the request is sent.
Default Body
There are a couple of ways to interact with the request body to prepare it to be sent. You can either use the methods mentioned below to add to the body on any given instance or you can use the defaultBody
method on your request. This is recommended because you could then define any requirements as constructor arguments in your request and then standardise your request even more.
While you are expected to return a raw string for the XML body, it can be tedious to write XML as text. We have built a library, XML Wrangler which allows you to read and write XML in a more developer-friendly way.
Interacting with the body() method
While you can define the default body on your request, it might be useful to add or modify the body at runtime on a per-request basis. Saloon has the following methods to allow you to modify the XML request body:
set(string $value) -> Overwrite the XML body entirely
all(): array -> Get the XML body
isEmpty(): bool -> Check if the body is empty
isNotEmpty(): bool -> Check if the body is not empty
Connector Body
You can add the same interface and trait to your connector. If you have the trait on both the connector and the request, the body on the request will take priority. If you have the body on just the connector but not on the request, the request will inherit the body on the connector.
XML Wrangler
You may be interested in a third-party library written by the maintainer of Saloon - XML Wrangler. It provides a modern syntax for reading and writing XML in PHP.
