Android DefaultHttpClient、HttpPost 等已弃用 (SDK 30)

Question

我更新了我的应用程序，但找不到我们用来上传图片的新功能。

    String photoBase64 = ConvertBitmapToString(selectPhotoBitmap);

    ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("image", "data:image/png;base64," + photoBase64));
    nameValuePairs.add(new BasicNameValuePair("name", selectPhotoName));

    Thread t = new Thread(new Runnable() {

        @Override
        public void run() {
            try {
                HttpClient httpclient = new DefaultHttpClient();
                HttpPost httppost = new HttpPost(config.FTP + "upload.php");
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                httpclient.execute(httppost);
            } catch (Exception e) {

                e.printStackTrace();
            }
        }
    });
    t.start();

已弃用：

NameValuePair in org.apache.http has been deprecated
BasicNameValuePair(String,String) in BasicNameValuePair has been deprecated
DefaultHttpClient() in DefaultHttpClient has been deprecated
HttpPost(String) in HttpPost has been deprecated
UrlEncodedFormEntity in org.apache.http.client.entity has been deprecated
UrlEncodedFormEntity(List<? extends NameValuePair>) in UrlEncodedFormEntity has been deprecated
setEntity(HttpEntity) in HttpEntityEnclosingRequestBase has been deprecated
execute(HttpUriRequest) in HttpClient has been deprecated

我怎样才能用新的来改变它们。

您可以使用 HttpURLConnection https://developer.android.com/reference/java/net/HttpURLConnection 或者如果您想继续使用 httpclient 添加

android {
    useLibrary 'org.apache.http.legacy' }

将图像作为文件而不是 base64 发送到服务器

MultipartEntityBuilder builder = MultipartEntityBuilder.create();

         
            builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
//Here image is the absolute path of the file you want to post
            FileBody fbd=new FileBody(new File(image));
            builder.addPart("my_file",fbd);

            for (int index = 0; index < nameValuePairs.size(); index++) {
                builder.addPart(nameValuePairs.get(index).getName(),new StringBody(nameValuePairs.get(index).getValue(),ContentType.TEXT_PLAIN));

            }

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

            HttpEntity entity = builder.build();

            httpPost.setEntity(entity);

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