HTTPclient使用MultipartEntity怎么上传文件

Answer 1

<form action="http://localhost/index.html" method="POST"
enctype="multipart/form-data">
<input type="text" name="param1" value="测试"/>
<input type="text" name="param2" value="value2"/>
<input type="file" name="param3"/>
<inupt type="submit" value="submit"/>
</form>

MultipartEntity entity = new MultipartEntity();
entity.addPart("param1", new StringBody("测试", Charset.forName("UTF-8")));
entity.addPart("param2", new StringBody("value2", Charset.forName("UTF-8")));
entity.addPart("param3", new FileBody(new File("C:\\1.txt")));

HttpPost request = new HttpPost(“http://localhost/index.html”);
request.setEntity(entity);
