Question

我尝试使用ESB mule将发布请求发送到API。因此我创造了这样的流程。

        </message-properties-transformer>
        <set-payload value="fetchTokenRequest" doc:name="Set Payload"/>
        <set-property propertyName="Content-Type" value="application/json" doc:name="Property"/>

        <http:request config-ref="HTTP_Request_Configuration" path="/api_requests/secure_request" method="POST" doc:name="HTTP">
            <http:success-status-code-validator values="0..599"/>
        </http:request>
    </flow>
</mule>

在API文档中，他们提供了java发送和接收响应的示例代码，它也在我的本地工作。 java代码片段如下所示。

import org.json.JSONObject;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.URL;
import java.net.HttpURLConnection;

public class FetchToken {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try {
            String devId = "t******I";
            String certId = "l*******F";

            URL url = new URL("https://api.bonanza.com/api_requests/secure_request");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();

            connection.setRequestMethod("POST");
            connection.setDoOutput(true);
            connection.setRequestProperty("Accept", "application/json");
            connection.setRequestProperty("X-BONANZLE-API-DEV-NAME", devId);
            connection.setRequestProperty("X-BONANZLE-API-CERT-NAME", certId);

            OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());

            String requestName = "fetchTokenRequest";

            writer.write(requestName);
            writer.flush();
            writer.close();

            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String response = in.readLine();

            JSONObject jsonResponse = new JSONObject(response);

            if (jsonResponse.optString("ack").equals("Success") 
                    && jsonResponse.optJSONObject("fetchTokenResponse") != null) {
                // Success! Now read more keys from the json object
                JSONObject fetchTokenJson = jsonResponse.optJSONObject("fetchTokenResponse");

                System.out.println("Your token: " + fetchTokenJson.optString("authToken"));
                System.out.println("Token expiration time: " + fetchTokenJson.optString("hardExpirationTime"));
                System.out.println("Authentication URL: " + fetchTokenJson.optString("authenticationURL"));
            }


        } catch (Exception e) {
            System.out.println(e);
        }
    }
}

我不是java专长。他们如何在上面的示例中用Java发送post payload（fetchTokenRequest）。如何在mule ESB中发送相同的有效负载。

如果是流后有效负载，我如何在ESB mule中发送流后有效负载？

Answer 1

在您的示例中，您的http侦听器正在侦听的任何有效负载都将是您发布请求的有效负载。要使用其他有效负载，请在出站http。

之前使用<set-payload doc:name="Set Payload" value="your_value"/>

将Content-Type设为application/json 在set-payload之后，请使用<json:object-to-json-transformer/>

在ESB mule中发送POST请求
