PublishRequest (AWS Java SDK for Amazon SNS 1.9.22 API)

java.lang.Object
- com.amazonaws.AmazonWebServiceRequest
- - com.amazonaws.services.sns.model.PublishRequest

All Implemented Interfaces:

Serializable
```
public class PublishRequest
extends com.amazonaws.AmazonWebServiceRequest
implements Serializable
```
Container for the parameters to the Publish operation.
Sends a message to all of a topic's subscribed endpoints. When a messageId is returned, the message has been saved and Amazon SNS will attempt to deliver it to the topic's subscribers shortly. The format of the outgoing message to each subscribed endpoint depends on the notification protocol selected.

To use the Publish action for sending a message to a mobile endpoint, such as an app on a Kindle device or mobile phone, you must specify the EndpointArn. The EndpointArn is returned when making a call with the CreatePlatformEndpoint action. The second example below shows a request and response for publishing to a mobile endpoint.

- Constructor Detail
  - PublishRequest
```
public PublishRequest()
```
    Default constructor for a new PublishRequest object. Callers should use the setter or fluent setter (with...) methods to initialize this object after creating it.
  - PublishRequest
```
public PublishRequest(String topicArn,
              String message)
```
    Constructs a new PublishRequest object. Callers should use the setter or fluent setter (with...) methods to initialize any additional object members.
    Parameters:
    topicArn - The topic you want to publish to.
    message - The message you want to send to the topic.
    If you want to send the same message to all transport protocols, include the text of the message as a String value.
    If you want to send different messages for each transport protocol, set the value of the MessageStructure parameter to json and use a JSON object for the Message parameter. See the Examples section for the format of the JSON object.
    Constraints: Messages must be UTF-8 encoded strings at most 256 KB in size (262144 bytes, not 262144 characters).
    JSON-specific constraints:
    
    Keys in the JSON object that correspond to supported transport protocols must have simple JSON string values.
    
    The values will be parsed (unescaped) before they are used in outgoing messages.
    
    Outbound notifications are JSON encoded (meaning that the characters will be reescaped for sending).
    
    Values have a minimum length of 0 (the empty string, "", is allowed).
    
    Values have a maximum length bounded by the overall message size (so, including multiple protocols may limit message sizes).
    
    Non-string values will cause the key to be ignored.
    
    Keys that do not correspond to supported transport protocols are ignored.
    
    Duplicate keys are not allowed.
    
    Failure to parse or validate any key or value in the message will cause the Publish call to return an error (no partial delivery).
