Question

我想在设置Content-Type之后使用MultipartEntityBuilder将文件从Android上传到服务器，但也无法上传。

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);

MultipartEntityBuilder builder = MultipartEntityBuilder.create();        
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

Log.d("Name", firstname+" "+lastname);

builder.addTextBody("firstName", firstname);
builder.addTextBody("lastName", lastname);

Log.d("ProfilePicturePath", picture);

if (picture.length()>0) {
    builder.addPart("picture", new FileBody(new File(picture)));
}

Log.d("Boundary", boundary);
Log.d("URL", url);

String credentials = Base64.encodeToString((username+":"+password).getBytes(), Base64.NO_WRAP);

httpPost.setHeader("Authorization", "Basic "+credentials);
httpPost.setHeader("Content-Type", "multipart/form-data; boundary=" + boundary);

Log.d("BasicAuthorization", credentials);

httpPost.setEntity(builder.build());

HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();

请仔细阅读我的代码，并向我提出一些解决方案。

您可以使用FileBody更新文件。这是一个小例子。

FileBody fileBody = new FileBody(file);
StringBody stringBody1 = new StringBody("Message 1", ContentType.MULTIPART_FORM_DATA);
StringBody stringBody2 = new StringBody("Message 2", ContentType.MULTIPART_FORM_DATA);
// 
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
builder.addPart("upfile", fileBody);
builder.addPart("text1", stringBody1);
builder.addPart("text2", stringBody2);
HttpEntity entity = builder.build();
//
post.setEntity(entity);

您可以使用getContentType

获取内容类型

entity.getContentType()
