本文整理了Java中java.io.DataOutputStream.writeBytes()方法的一些代码示例，展示了DataOutputStream.writeBytes()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。DataOutputStream.writeBytes()方法的具体详情如下：
包路径：java.io.DataOutputStream
类名称：DataOutputStream
方法名：writeBytes

DataOutputStream.writeBytes介绍

[英]Writes out the string to the underlying output stream as a sequence of bytes. Each character in the string is written out, in sequence, by discarding its high eight bits. If no exception is thrown, the counter written is incremented by the length of s.
[中]将字符串作为字节序列写入基础输出流。字符串中的每个字符都是通过丢弃其高8位按顺序写出的。如果未引发异常，计数器written将按s的长度递增。

request.writeBytes(this.twoHyphens + this.boundary + this.crlf);
request.writeBytes("Content-Disposition: form-data; name=\"" +
  this.attachmentName + "\";filename=\"" + 
  this.attachmentFileName + "\"" + this.crlf);
request.writeBytes(this.crlf);
