Function Compute：Penanganan kesalahan

Tipe kesalahan

• Jika terjadi kesalahan saat suatu fungsi dijalankan, Function Compute akan menangkap kesalahan tersebut dan mengembalikan pesan kesalahan.

  Contoh kode:

  package example;
  
  import com.aliyun.fc.runtime.Context;
  import com.aliyun.fc.runtime.StreamRequestHandler;
  
  import java.io.IOException;
  import java.io.InputStream;
  import java.io.OutputStream;
  
  public class HelloFC implements StreamRequestHandler {
  
      @Override
      public void handleRequest(InputStream inputStream, OutputStream outputStream, Context context) throws IOException {
          throw new IOException("oops");
      }
  } 

  Saat fungsi dipanggil, respons berikut dikembalikan:

  {
    "errorMessage" : "oops",
    "errorType" : "java.io.IOException",
    "errorCause" : "oops",
    "stackTrace" : [ "example.HelloFC.handleRequest(HelloFC.java:15)" ]
  }

• Jika fungsi keluar secara proaktif selama proses berjalan, sistem akan mengembalikan pesan kesalahan umum.

  Contoh kode:

  package example;
  
  import java.io.IOException;
  import java.io.InputStream;
  import java.io.OutputStream;
  
  import com.aliyun.fc.runtime.Context;
  import com.aliyun.fc.runtime.StreamRequestHandler;
  
  public class App implements StreamRequestHandler {
  
      @Override
      public void handleRequest(InputStream inputStream, OutputStream outputStream, Context context) throws IOException {
          System.exit(-1);
      }
  }

  Saat fungsi dipanggil, respons berikut dikembalikan:

  {
    errorMessage: 'Proses keluar secara tak terduga sebelum menyelesaikan permintaan (Durasi: 43ms, maxMemoryUsage: 65MB)'
  }
