编辑MultiPartEntity的标头

Question

我正在使用MultiPartEntity在我的Android应用程序中创建一个XML +图像post，除了我要发布的服务器要求我将HTTP post的Content-Type设置为application/soap+xml; charset="utf-8"之外，一切都很好

那么我怎么才能把它从这个改变...

POST / HTTP/1.1
Host: 192.168.0.193:1234
User-Agent: Apache-HttpClient/UNAVAILABLE (java 1.4)
Content-Type: multipart/form-data; boundary=XR43mUmjvTb58T7crHhgj83C84qmZO_9k0-s
Content-Length: 28150
Connection: Keep-Alive

--XR43mUmjvTb58T7crHhgj83C84qmZO_9k0-s
...

到这个

POST / HTTP/1.1
Host: 192.168.0.193:1234
User-Agent: Apache-HttpClient/UNAVAILABLE (java 1.4)
Content-Type: application/soap+xml; charset="utf-8"
Content-Length: 28150
Connection: Keep-Alive

--XR43mUmjvTb58T7crHhgj83C84qmZO_9k0-s
...

这可能不是发布它的正确方式，但我必须这样做，它会起作用的。

我找到了一种方法，它只需向HttpPost对象添加一个头文件。

        MultipartEntity entity = new MultipartEntity();
        entity.addPart(xml);
        entity.addPart(image);

        httppost.addHeader("Content-Type", "application/soap+xml; charset=\"utf-8\"");
        httppost.setEntity(entity);

        HttpResponse response = httpclient.execute(httppost);
