@polywrap/http-plugin-js

Http plugin curently supports two different methods GET and POST. Similar to calling axios, when defining request you need to specify a response type. Headers and query parameters may also be defined.

Response Types

TEXT - The server will respond with text, the HTTP plugin will return the text as-is.

BINARY - The server will respond with binary data (ArrayBuffer), the HTTP plugin will encode as a base64 string and return it.

GET request

Below is sample invocation of the GET request with custom request headers and query parameters (urlParams).

const response = await polywrapClient.invoke<Response>({
  uri: new Uri("wrap://ens/http.polywrap.eth"),
  method: "get",
  args: {
    url: "http://www.example.com/api"
    request: {
      responseType: "TEXT"
      urlParams: [{key: "query", value: "foo"}]
      headers: [{key: "X-Request-Header", value: "req-foo"}]
    }
  }
})

POST request

Below is sample invocation of the POST request with custom request headers and query parameters (urlParams). It is also possible to set request body as shown below.

const response = await polywrapClient.invoke<Response>({
  uri: new Uri("wrap://ens/http.polywrap.eth"),
  method: "post",
  args: {
    url: "http://www.example.com/api"
    request: {
      responseType: "TEXT"
      urlParams: [{key: "query", value: "foo"}]
      headers: [{key: "X-Request-Header", value: "req-foo"}]
      body: "{data: 'test-request'}"
    }
  }
})
