标签: multipartentity

我正在尝试使用 HttpPost 和 MultipartEntityBuilder 的文件上传 API。以下是我使用过的代码。

MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setCharset(MIME.UTF8_CHARSET);
builder.addBinaryBody(<fileFieldName>, <byteArray>, ContentType.TEXT_PLAIN, <fileName>);

文件已正确上传。但是，当文件名包含非 ASCII 字符时，它会以名称“????.jpg”上传。尝试了此处给出的解决方案/sf/answers/1810921101/。但这并没有解决我的问题。请协助。

下面是我编写的用于将二进制文件沿某些字符串发送到PHP Web应用程序服务器的代码.

public void doRegister(final String userEmail, final String userPass, final File userPhotoId) {
    HttpClient myHttpClient = new DefaultHttpClient();
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                HttpPost registerTry = new HttpPost(Constants.oAuthRegURL);
                MultipartEntity signupEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
                signupEntity.addPart("email", new StringBody(userEmail, Charset.forName("UTF-8")));
                signupEntity.addPart("password", new StringBody(userPass, Charset.forName("UTF-8")));
                signupEntity.addPart("User[profilePicture]", new FileBody(userPhotoId, "image/jpeg"));
                registerTry.setEntity(signupEntity);
                HttpResponse signupHttpResp = myHttpClient.execute(registerTry);
            } catch (ClientProtocolException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    }).start();
}

文件 …

我确实使用MultipartEntity将File发送到服务器,它在$_FILES超全局中正确显示

但我还需要填写POST正文以供阅读 php://stdin

我怎样才能做到这一点？

下面的当前片段:

ByteArrayOutputStream bos = new ByteArrayOutputStream(); // stream to hold image
bm.compress(CompressFormat.JPEG, 75, bos); //compress image
byte[] data = bos.toByteArray(); 
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost("REMOTE ADDRESS");
ByteArrayBody bab = new ByteArrayBody(data, "image.jpg");
MultipartEntity reqEntity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE); // is this one causing trouble?
reqEntity.addPart("image", bab); // added image to request
// tried this with no luck
// reqEntity.addPart("", new StringBody("RAW DATA HERE")); 
postRequest.setEntity(reqEntity); // set the multipart entity …

我想使用将文件(特定于图像)上传到REST服务器HTTP POST.我已经导入/添加到构建路径httpmime-4.3.1.jar和apache-mime4j-0.6.jar.我在堆栈跟踪中得到以下错误.

这有效吗？ post.setHeader("enctype", "multipart/form-data");

HTTP POST代码

public void multiPartPost() throws ClientProtocolException, IOException {
    File image = new File(EXTERNALSTORAGE + "/Pictures/sample.jpg");
    FileBody fileBody = new FileBody(image);

    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost(url);
    post.setHeader("enctype", "multipart/form-data");

    MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();
    multipartEntity.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
    multipartEntity.addPart("sampleImage", fileBody);
    post.setEntity(multipartEntity.build());

    HttpResponse response = client.execute(post);
    String responseBody = EntityUtils.toString(response.getEntity());
    Log.v("multiPartPost HTTP Response", responseBody);
}

我按照这里提到的建议但无法解决错误.如何将外部依赖项(jar文件)添加到android studio？

请告诉我在这里缺少什么？
