Apache HttpClient POST上傳文件不會與MultipartEntityBuilder上傳

Question

我有一個HTML表單，其中有一個文件上傳。我試圖通過使用MultipartEntityBuilder的表單上傳Word文檔，但它不起作用。

表單中有幾個文本輸入和2個文件上傳行。如果我使用BasicNameValuePair方法並將這些字段設置爲空字符串，則文本字段會正確提交。由於我需要上傳文件，因此我更改爲MultipartEntityBuilder，甚至無法再次進行基本測試。

工作守則

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); 

試圖MultipartEntityBuilder

// Everything up to and including the Headers remain the same 

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

StringBody sb = new StringBody("Value1", ContentType.TEXT_PLAIN); 
builder.addPart("textField1", sb); 

sb = new StringBody("Value2", ContentType.TEXT_PLAIN); 
builder.addPart("textField2", sb); 

FileBody fb = new FileBody(new File("path to file"), ContentType.DEFAULT_BINARY); 
builder.addPart("fileField1", fb); 

fb = new FileBody(new Field("path to file2"), ContentType.DEFAULT_BINARY); 
builder.addPart("fileField2", fb); 

httppost.setEntity(builder.build()); 

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

形式是由Oracle託管，並取回錯誤：

An unexpected error occurred: ORA-06501: PL/SQL: program error

我有也嘗試過這些其他的方法：

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()); 

除了試圖通過把一切在builder.addTextBody()像我原來的工作測試，模仿我的第一次測試，但仍得到相同的結果。

Answer 1

前段時間，我花了很多時間試圖提交多形式的文件。最後問題通過添加邊界來解決。據我瞭解，一些調試服務器無法識別沒有它的部件。

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); 

Answer 2

嘗試刪除這條線

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

更新

預期應用程序發送無效的Content-Type頭

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

請不要手動設置Content-Type和讓HttpClient創根據請求中包含的HttpEntity的屬性對您進行打包
