Java Apache HttpClient上传后文件赢得'；无法使用MultipartEntityBuilder上载

我有一个HTML表单，里面有一个文件上传。我正试图使用

MultipartEntityBuilder

通过表单上传Word文档，但它不起作用

表单中有几个文本输入和两行文件上传行。如果我使用

BasicNameValuePair

方法并将这些字段设置为空字符串，则文本字段将正确提交。由于我需要上传文件，我改为

MultipartEntityBuilder

，甚至无法让基本测试再次工作

工作代码

HttpClient client = HttpClientBuilder.create().build();
String uploadUrl = "http://somepage.com/upload";

HttpPost httppost = new HttpPost(uploadUrl);

httppost.setHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");
httppost.setHeader("Content-Type", "multipart/form-data");
httppost.setHeader("Accept-Encoding", "gzip, deflate");

List<NameValuePair> formparams = new ArrayList<NameValuePair>();

formparams.add(new BasicNameValuePair("testField1", "Value1"));
formparams.add(new BasicNameValuePair("testField2", "Value2"));
formparams.add(new BasicNameValuePair("fileField1", ""));
formparams.add(new BasicNameValuePair("fileField2", ""));

httppost.setEntity(new UrlEncodedFormEntity(formparams, Consts.UTF_8));

HttpResponse response = client.execute(httppost, httpContext);

该表单由Oracle托管并返回错误：

发生意外错误：ORA-06501:PL/SQL:程序错误

我还尝试了以下其他方法：

builder.addTextBody("textField1", "Value1");
builder.addTextBody("textField2", "Value2");

File file1 = new File("path to file1");
builder.addBinaryBody("fileField1", file1, ContentType.DEFAULT_BINARY, file1.getName());

File file2 = new File("path to file2");
builder.addBinaryBody("fileField2", file2, ContentType.DEFAULT_BINARY, file2.getName());

以及尝试模拟我的第一个测试，将所有内容放入

builder.addTextBody（）

中，就像我最初的工作测试一样，但仍然得到相同的结果

调试[org.apache.http.headers]http-outgoing-4不久前，我花了很多时间试图提交包含文件的多部分表单。最后，通过添加边界解决了问题。正如我在一些调试之后所理解的，没有边界，服务器无法识别部分

String boundary = "---------------"+UUID.randomUUID().toString();
multipartEntityBuilder.setBoundary(boundary);
...
HttpPost request = new HttpPost(uriBuilder.build());
request.setHeader("Content-Type", ContentType.MULTIPART_FORM_DATA.getMimeType()+";boundary="+boundary);
...
multipartEntityBuilder.addBinaryBody("document[file]", dataBytes, ContentType.APPLICATION_OCTET_STREAM, name);

尝试删除此行

httppost.setHeader("Content-Type", "multipart/form-data");

已更新

正如预期的那样，应用程序正在发送无效的内容类型标头

[org.apache.http.headers] http-outgoing-5 >> Content-Type: multipart/form-data

请不要手动设置
内容类型
，让HttpClient根据请求中包含的
HttpEntity
的属性为您生成内容类型
我为此挣扎了……太久。几个小时了！无论如何，我没有
