我正在尝试将一些数据发布到服务器，但没有得到预期的结果。我得到 200 OK 响应，但返回的 html 源有一个字符串，上面写着“错误 - 404 页面未找到”

我认为我发送的数据集有问题。也许我错过了一些东西，因为我以前从未使用过多格式数据。

这是发送的多格式数据（我使用篡改数据来检查发送的内容

    POSTDATA =-----------------------------124853047628807
Content-Disposition: form-data; name="mgnlModelExecutionUUID"

4ee01e05-dc16-4535-a222-693b98ec9b69
-----------------------------124853047628807
Content-Disposition: form-data; name="field"


-----------------------------124853047628807
Content-Disposition: form-data; name="name"

test
-----------------------------124853047628807
Content-Disposition: form-data; name="surname"

test
-----------------------------124853047628807
Content-Disposition: form-data; name="age"

test
-----------------------------124853047628807--

为了发送这些数据，我所做的是创建一个 MultipartEntityBuilder，如下所示：

    StringBody name = new StringBody("test", ContentType.MULTIPART_FORM_DATA);
    StringBody surname = new StringBody("test", ContentType.MULTIPART_FORM_DATA);
    StringBody age = new StringBody("test", ContentType.MULTIPART_FORM_DATA);
    StringBody field = new StringBody("", ContentType.MULTIPART_FORM_DATA);
    MultipartEntityBuilder builder = MultipartEntityBuilder.create();
    builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

    builder.addPart("name", name);
    builder.addPart("surname", surname);
    builder.addPart("age", age);
    builder.addPart("field",field);


    return builder;

最重要的是，我发送的标题如下：

 post.addHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:29.0) Gecko/20100101 Firefox/29.0");
        post.addHeader("Accept", "text/html,application/xhtml xml,application/xml;q=0.9,*/*;q=0.8");

我试图设置多格式标题，但它不起作用

post.addHeader("Content-type", "multipart/form-data");

关于我可能遗漏的任何建议？谢谢你

尝试这个 ！

        File file = new File(path);


        File image = new File("/storage/emulated/0/DCIM/100MEDIA/a_thumbnail.jpg");
        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost(urls[0]);
        HttpResponse response = null ;
        post.setHeader("Authorization","----------------------------");





        MultipartEntity ent = new MultipartEntity();
        try {

            ent.addPart("user_id",new StringBody("1"));
            ent.addPart("categories_id",new StringBody("3"));
            ent.addPart("tags",new StringBody("mama"));
            ent.addPart("title",new StringBody("mama"));
            ent.addPart("preview_id",new StringBody("2"));
            ent.addPart("thumb", new FileBody(image));
            ent.addPart("video", new FileBody(file));


            post.setEntity(ent);

            response = client.execute(post);

            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
            answer= answer+bufferedReader.readLine();

        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


        return answer;
    }

我知道我在使用我为发布一些文本和一些二进制文件而编写的代码时遇到了问题，最后我为自己编写了整个应用程序/multipartform。

HttpURLConnection conn = (HttpURLConnection) url.openConnection();

        conn.setDoInput(true);
        conn.setDoOutput(true);
        conn.setUseCaches(false);
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Connection", "Keep-Alive");
        conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundry);
        conn.setRequestProperty("Authorization", "----------------------------");



        DataOutputStream out = new DataOutputStream(conn.getOutputStream());
        out.writeBytes(twoHiphens+boundry+lineend);
        out.writeBytes("Content-Disposition: form-data; name=\"user_id\""+lineend+lineend);
        out.writeBytes("1"+lineend);

        out.writeBytes(twoHiphens+boundry+lineend);
        out.writeBytes("Content-Disposition: form-data; name=\"preview_id\""+lineend+lineend);
        out.writeBytes("1"+lineend);

        out.writeBytes(twoHiphens+boundry+lineend);
        out.writeBytes("Content-Disposition: form-data; name=\"categories_id\""+lineend+lineend);
        out.writeBytes("2"+lineend);

        out.writeBytes(twoHiphens+boundry+lineend);
        out.writeBytes("Content-Disposition: form-data; name=\"title\""+lineend+lineend);
        out.writeBytes("Mama"+lineend);

        out.writeBytes(twoHiphens+boundry+lineend);
        out.writeBytes("Content-Disposition: form-data; name=\"tags\""+lineend+lineend);
        out.writeBytes("mama"+lineend);


        out.flush();


        out.writeBytes(twoHiphens+boundry+lineend);
        out.writeBytes("Content-Disposition: form-data; name=\"video\"; filename=\""+file.getName()+"\""+lineend);
        out.writeBytes(lineend);
        Log.d("UPLOAD", "Titlul video-ului ="+file.getName());



        //decoding of bytes from video
        FileInputStream file_stream = new FileInputStream(file);
        bytesAvailable =file_stream.available();
        bufferSize = Math.min(bytesAvailable,maxBufferSize);
        buffer = new byte[bufferSize];
        Log.d("UPLOAD", "Bytes Read Video =" +bytesRead);

        bytesRead = file_stream.read(buffer);
        //writting to outputstream
        while (bytesRead >0){
            out.write(buffer, 0, bytesRead);
            bytesRead=file_stream.read(buffer);

        }
        Log.d("UPLOAD", "Done Loading first buffer");

        file_stream.close();

        out.writeBytes(twoHiphens+boundry+lineend);
        out.writeBytes("Content-Disposition: form-data; name=\"thumb\"; filename=\""+image.getName()+"\""+lineend);
        out.writeBytes(lineend);
        Log.d("UPLOAD", "Titlul preview-ului ="+image.getName());

        //decodint image bytes
        FileInputStream image_stream = new FileInputStream(image);
        int bytesRead2;
        int bytesAvailable2, bufferSize2 ;
        bytesAvailable2 = image_stream.available();
        bufferSize2 = Math.min(bytesAvailable2, maxBufferSize);
        byte []buffer2 = new byte[bufferSize2];


        //writing to outputstream
        bytesRead2 = image_stream.read(buffer2);
        while(bytesRead2>0){
            out.write(buffer2, 0, bytesRead2); //                   bytesAvailable2 = image_stream.available();
            bytesRead2 = image_stream.read(buffer2);
        }
        image_stream.close();

        Log.d("UPLOAD", "Done loading the second buffer");

        out.writeBytes(twoHiphens+boundry+twoHiphens+lineend);
        out.writeBytes(lineend);

        out.flush();
        out.close();



        Log.d("UPLOAD","Response Code = "+conn.getResponseCode());
        String responseMessage = conn.getResponseMessage();
        Log.d("UPLOAD", "Response Message  = "+responseMessage);


        InputStream  in;
        if(conn.getResponseCode() >= 400){
            in = conn.getErrorStream();
            }else{
                in = conn.getInputStream();
            }
            BufferedReader reader = new BufferedReader(new InputStreamReader(in,"UTF-8"));
            StringBuilder response = new StringBuilder();
            char []bytes = new char[512];
            int read ;
            while((read = reader.read(bytes))!=-1){
                response.append(bytes, 0, read);
            }

            Log.d("UPLOAD", "Response " +response);


            conn.disconnect();

您可以省略引用二进制数据的代码。希望能给你一些帮助

也许每个 StringBody 的 Content Type 不能是 ContentType.MULTIPART_FORM_DATA 。也许应该是“text/plain”
