Amazon Web ServicesAmazon SQS 消息队列 API

批量发送消息

一次向指定队列投递最多 10 条消息。 官方英文详细说明： <p>You can use <code>SendMessageBatch</code> to send up to 10 messages to the specified queue by assigning either identical or different values to each message (or by not assigning values at all). This is a batch version of <code> <a>SendMessage</a>.</code> For a FIFO queue, multiple messages within a single batch are enqueued in the order they are sent.</p> <p>The result of sending each message is reported individually in the response. Because the batch request can result in a combination of successful and unsuccessful actions, you should check for batch errors even when the call returns an HTTP status code of <code>200</code>.</p> <p>The maximum allowed individual message size and the maximum total payload size (the sum of the individual lengths of all of the batched messages) are both 1 MiB 1,048,576 bytes.</p> <important> <p>A message can include only XML, JSON, and unformatted text. The following Unicode characters are allowed. For more information, see the <a href="http://www.w3.org/TR/REC-xml/#charsets">W3C specification for characters</a>.</p> <p> <code>#x9</code> | <code>#xA</code> | <code>#xD</code> | <code>#x20</code> to <code>#xD7FF</code> | <code>#xE000</code> to <code>#xFFFD</code> | <code>#x10000</code> to <code>#x10FFFF</code> </p> <p>If a message contains characters outside the allowed set, Amazon SQS rejects the message and returns an InvalidMessageContents error. Ensure that your message body includes only valid characters to avoid this exception.</p> </important> <p>If you don't specify the <code>DelaySeconds</code> parameter for an entry, Amazon SQS uses the default value for the queue.</p>
