Provides a general use object that can be used to send and receive HTTP requests. The object created by this function is a wrapper around Java's HttpClient class. Usage requires creating a JythonHttpClient object with a call to system.net.httpClient, then calling a method (such as get(), post()) on the JythonHttpClient to actually issue a request.
This scripting function has no Client Permission restrictions.
system.net.httpClient([timeout], [bypass_cert_validation], [username], [password], [proxy], [cookie_policy], [redirect_policy], [customizer])
Integer timeout - A value, in milliseconds, to set the client’s connect timeout setting to. Defaults to 60000. [optional]
Boolean bypass_cert_validation - A boolean indicating whether the client should attempt to validate the certificates of remote servers, if connecting via HTTPS/SSL. Defaults to False. [optional]
String username - A string indicating the username to use for authentication if the remote server requests authentication; specifically, by responding with a WWW-Authenticate or Proxy-Authenticate header. Only supports Basic authentication. If username is specified but not password, an empty string will be used for the password in the Basic Authentication response. Defaults to None. [optional]
String password - A string indicating the password to use for authentication. Defaults to None. [optional]
String proxy - The address of a proxy server, which will be used for HTTP and HTTPS traffic. If a port is not specified as part of that address, it will be assumed from the protocol in the URL, i.e. 80/443. Defaults to None. [optional]
String cookie_policy - A string representing this client’s cookie policy. Accepts values "ACCEPT_ALL", "ACCEPT_NONE", and "ACCEPT_ORIGINAL_SERVER" . [Defaults to "ACCEPT_ORIGINAL_SERVER"]
String redirect_policy - A string representing this client’s redirect policy. Acceptable values are listed below. Defaults to "Normal". [optional]
"NEVER" - never allow redirects"ALWAYS" - allow redirects "NORMAL" - allows redirects, except those that would downgrade to insecure addresses (i.e., HTTPS redirecting to HTTP)Callable customizer - A reference to a function. This function will be called with one argument (an instance of HttpClient.Builder). The function should operate on that builder instance, which allows for customization of the created HTTP client. Defaults to None. [optional]
JythonHttpClient - An object wrapped around an instance of Java's HttpClient class. The httpClient object has methods that can be called to execute HTTP requests against a server. See the panel below for more details.
Gateway, Vision Client, Perspective Session
Once a JythonHttpClient object has been created, it can be used to handle many HTTP requests without needing to create a new client. Individual HTTP requests can be made with the methods detailed below.
Each JythonHttpClient instance has an attached CookieManager. This CookieManager can be accessed to retrieve cookies set by external web services, or to set cookies (i.e., for authentication) before a request is made.
This section documents the Response object, returned by the request methods on the JythonHttpClient object. This object is simply a wrapper for Java's HTTPResponse object.
This section documents the Promise object, which is returned by the asynchronous methods available on the JythonHttpClient object. This object is a wrapper around Java's CompletableFuture class, and will return some different object once completed with .get().
This section documents the RequestWrapper object, which is simply a wrapper around Java's HTTPRequest object. This object can be used to determine details about the request that was originally sent to populate a Response object.
# Create the JythonHttpClient.
client = system.net.httpClient()
# Sent a GET request.
response = client.get("https://httpbin.org/get", params={"a": 1, "b": 2})
# Validate the response.
if response.good:
# Do something with the response
print response.json['args']['a']
client = system.net.httpClient()
# Send a non-blocking request to an endpoint that will wait 3 seconds.
promise = client.getAsync("https://httpbin.org/delay/3", params={"a": 1, "b": 2})
# This will print before we get a response from the endpoint.
print "doing something while waiting..."
# do more work here...
# After the work on the previous lines, we can now block and wait for a response.
response = promise.get()
if response.good:
print response.json['args']['a']
