UnityWebRequest

class in UnityEngine.Networking

Switch to Manual

Description

The UnityWebRequest object is used to communicate with web servers.

UnityWebRequests handle the flow of HTTP communication with web servers. Other objects - specifically DownloadHandler and UploadHandler - govern downloading and uploading data, respectively.

A set of static functions are provided for convenience; these return UnityWebRequest objects properly configured for many common use cases. See: Get, Post, Put, GetTexture.

Note: Most properties on the UnityWebRequest object cannot be altered once the UnityWebRequest has begun communicating with a remote server by calling the SendWebRequest method.

Note: Proxy settings should be configured on Operating System level. UnityWebRequest picks these up later.

Static Variables

chunkedTransfer**Deprecated.**. HTTP/2 and many HTTP/1.1 servers don't support this; we recommend leaving it set to false (default).
disposeCertificateHandlerOnDisposeIf true, any CertificateHandler attached to this UnityWebRequest will have CertificateHandler.Dispose called automatically when UnityWebRequest.Dispose is called.
disposeDownloadHandlerOnDisposeIf true, any DownloadHandler attached to this UnityWebRequest will have DownloadHandler.Dispose called automatically when UnityWebRequest.Dispose is called.
disposeUploadHandlerOnDisposeIf true, any UploadHandler attached to this UnityWebRequest will have UploadHandler.Dispose called automatically when UnityWebRequest.Dispose is called.
downloadedBytesReturns the number of bytes of body data the system has downloaded from the remote server. (Read Only)
downloadHandlerHolds a reference to a DownloadHandler object, which manages body data received from the remote server by this UnityWebRequest.
downloadProgressReturns a floating-point value between 0.0 and 1.0, indicating the progress of downloading body data from the server. (Read Only)
errorA human-readable string describing any system errors encountered by this UnityWebRequest object while handling HTTP requests or responses. (Read Only)
isDoneReturns true after the UnityWebRequest has finished communicating with the remote server. (Read Only)
isHttpErrorReturns true after this UnityWebRequest receives an HTTP response code indicating an error. (Read Only)
isModifiableReturns true while a UnityWebRequest’s configuration properties can be altered. (Read Only)
isNetworkErrorReturns true after this UnityWebRequest encounters a system error. (Read Only)
methodDefines the HTTP verb used by this UnityWebRequest, such as GET or POST.
redirectLimitIndicates the number of redirects which this UnityWebRequest will follow before halting with a “Redirect Limit Exceeded” system error.
responseCodeThe numeric HTTP response code returned by the server, such as 200, 404 or 500. (Read Only)
timeoutSets UnityWebRequest to attempt to abort after the number of seconds in timeout have passed.
uploadedBytesReturns the number of bytes of body data the system has uploaded to the remote server. (Read Only)
uploadHandlerHolds a reference to the UploadHandler object which manages body data to be uploaded to the remote server.
uploadProgressReturns a floating-point value between 0.0 and 1.0, indicating the progress of uploading body data to the server.
uriDefines the target URI for the UnityWebRequest to communicate with.
urlDefines the target URL for the UnityWebRequest to communicate with.
useHttpContinueDetermines whether this UnityWebRequest will include Expect: 100-Continue in its outgoing request headers. (Default: true).

Constructors

UnityWebRequestCreates a UnityWebRequest with the default options and no attached DownloadHandler or UploadHandler. Default method is GET.

Public Functions
