编辑MultiPartEntity的标题

Question

我在我的Android应用程序中使用MultiPartEntity创建了一个XML +图像帖子，除了我发布的服务器要求我设置HTTP的Content-Type之外，一切都很好发布到application/soap+xml; charset="utf-8"

那么我该如何改变呢......

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法，但我必须这样做，而不是它会起作用。

我找到了一种方法，只需向HttpPost对象添加标题即可。

        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);
