java - 编辑 MultiPartEntity 的标题

Question

我正在使用 MultiPartEntity 在我的 Android 应用程序中发布 XML + 图片，一切都很好，除了我要发布到的服务器要求我设置 Content- HTTP post 的类型到application/soap+xml； charset="utf-8"

那么我该如何改变它...

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
...

对此

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
...

这可能不是正确的发布方式，但我必须这样做，否则它会起作用。

我找到了一种方法，只需将 header 添加到 HttpPost 对象即可。

        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);
