java - 在 ESB mule 中发送 POST 请求

Question

我尝试使用 ESB mule 将 post 请求发送到 API。因此我创建了这样的流程。

<?xml version="1.0" encoding="UTF-8"?>

<mule xmlns:json="http://www.mulesoft.org/schema/mule/json" xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"

            <add-message-property key="X-BONANZLE-API-CERT-NAME" value="l*****F"/>
        </message-properties-transformer>
        <set-payload value="fetchTokenRequest" doc:name="Set Payload"/>
        <set-property propertyName="Content-Type" value="application/json" doc:name="Property"/>
        <json:object-to-json-transformer doc:name="Object to JSON"/>
        <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。

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专业知识。在上面的示例中，他们如何使用 Java 发送 post 有效负载 (fetchTokenRequest)。我如何在 mule ESB 中发送相同的有效负载。

如果是流发布有效负载，我如何在 ESB mule 中发送流发布有效负载？

Answer 1

在您的示例中，您的 http 监听器正在监听的任何有效负载都将是您的 post 请求的有效负载。要使用不同的有效负载，请使用 <set-payload doc:name="Set Payload" value="your_value"/>在出站 http 之前。

设置Content-Type至application/json之后set-payload ，使用<json:object-to-json-transformer/>
