Retrieves data from a HTTP source.
http.get(url, query)
.then(function(response) {
...
});
or with await:
var response = await http.get(url, query);
Reference
This command accepts the following parameters:
| Variable | Required | Description
| |
|---|---|---|---|
| Input: | |||
| url | yes | the URL to retrieve | |
| query | optional | (object) the optional URL query string params
| |
| Output: | |||
| Function returns a Promise with the following data: | |||
| success | bool | true if command completed successfully | |
| error | string | error string if command has failed | |
| statusCode | (on success) The HTTP status code | ||
| headers | (on success) The array with HTTP headers | ||
| body | (on success) The string body of the reply | ||
Comments
This function makes an HTTP GET request to the specified URL. The query string may be added to the URL (example.com/?param1=1¶m2=2) or passes as a query object ({ param1: 1, param2: 2 }).
Limitations
The length of the body is limited to 4096 bytes.
Example
console.log("Doing http request...");
http.get("https://mysmartbots.com")
.then(function(response) {
console.log("http result:", response.body);
})
.then(function() {
// Gracefully stop the test script
exit();
});
A bit more complex example which provides the error handling:
console.log("Doing http request...");
http.get("https://mysmartbots.com")
.then(function(result) {
if(!result.success) {
// On error display the error message and stop the processing
console.log("HTTP error:", result.error);
throw "";
}
console.log("http result:", result.body);
})
.catch(function(err) {
// This block allows cancelling the processing chain with throw ""
if(err != "") { throw err; }
})
.then(function() {
// Gracefully stop the test script
exit();
});
