我正在开发一个应用程序,它通过使用 android 中的搜索 API 将图像发送到服务器来搜索图像的细节。我已经尝试过谷歌图片搜索 API,但它已被阻止。
我需要帮助,是否有任何其他 API 可用于通过将图像发送到服务器来搜索图像的细节?

public int uploadFile(String sourceFileUri) {

    String upLoadServerUri = "http://www.xxxxxxxxxxx.com";
    String fileName = sourceFileUri;
    HttpURLConnection conn = null;
    DataOutputStream dos = null;  
    String lineEnd = "\r\n";
    String twoHyphens = "--";
    String boundary = "*****";
    int bytesRead, bytesAvailable, bufferSize;
    byte[] buffer;
    int maxBufferSize = 2 * 1024 * 1024; 
    File sourceFile = new File(sourceFileUri); 


   if (!sourceFile.isFile()) {
     tv.setText("File Not Exist");
     return 0;
    }
        try { 
            // open a URL connection to the Servlet

            FileInputStream fileInputStream = new FileInputStream(sourceFile);
         URL url = new URL(upLoadServerUri);
         conn = (HttpURLConnection) url.openConnection(); // Open a HTTP  connection to  the URL
         conn.setDoInput(true); // Allow Inputs
         conn.setDoOutput(true); // Allow Outputs
         conn.setUseCaches(false); // Don't use a Cached Copy
         conn.setRequestMethod("POST");
         conn.setRequestProperty("Connection", "Keep-Alive");
         conn.setRequestProperty("ENCTYPE", "multipart/form-data");
         conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
         conn.setRequestProperty("uploaded_file", fileName); 
         dos = new DataOutputStream(conn.getOutputStream());

         dos.writeBytes(twoHyphens + boundary + lineEnd); 
         dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""+ fileName + "\"" + lineEnd);
         dos.writeBytes(lineEnd);

         bytesAvailable = fileInputStream.available(); // create a buffer of  maximum size

         bufferSize = Math.min(bytesAvailable, maxBufferSize);
         buffer = new byte[bufferSize];

         // read file and write it into form...
         bytesRead = fileInputStream.read(buffer, 0, bufferSize);  

         while (bytesRead > 0) {
           dos.write(buffer, 0, bufferSize);
           bytesAvailable = fileInputStream.available();
           bufferSize = Math.min(bytesAvailable, maxBufferSize);
           bytesRead = fileInputStream.read(buffer, 0, bufferSize);               
          }

         // send multipart form data necesssary after file data
         dos.writeBytes(lineEnd);
         dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

         // Responses from the server (code and message)
         serverResponseCode = conn.getResponseCode();
         //String serverResponseMessage = conn.getResponseMessage();

        // Log.i("uploadFile", "HTTP Response is : " + serverResponseMessage + ": " + serverResponseCode);
         if(serverResponseCode == 200){
             runOnUiThread(new Runnable() {
                  public void run() {
                      tv.setText("File Upload Completed.");
                   // Toast.makeText(MainActivity.this, "File Upload Complete.", Toast.LENGTH_SHORT).show();
                  }
              });                
         }    

         //close the streams
         fileInputStream.close();
         dos.flush();
         dos.close();

    }

任何制作这些 API 的大公司都会免费为开发人员提供有限数量的 API 请求的访问权限,然后他们会为此向您收费或限制访问权限,除非您与他们达成某种许可协议(不适用于独立开发商)。话虽如此,对于爱好项目或其他东西,这些可能就足够了。

例如,您可以试用 WikiMedia API:

这是一篇关于各种可用 Api 的好文章:
