在ESB Mule中为API发送POST请求

Question

我尝试使用ESB ule子将发布请求发送到API。 因此，我创建了如下所示的流程。

     <?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"
    xmlns:spring="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd

    <flow name="bonanza_fetchtoken_ceFlow">
        <http:listener config-ref="HTTP_Listener_Configuration" path="/fetchtoken" allowedMethods="GET" doc:name="HTTP"/>
        <message-properties-transformer doc:name="Message Properties">
            <add-message-property key="X-BONANZLE-API-DEV-NAME" value="t**********I"/>
            <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="text/plain" doc:name="Property"/>
        <set-property propertyName="Accept" value="application/json" doc:name="Property"/>
        <http:request config-ref="HTTP_Request_Configuration" path="/api_requests/secure_request" method="POST" doc:name="HTTP" followRedirects="true" parseResponse="false">
            <http:success-status-code-validator values="0..599"/>
        </http:request>
    </flow>
</mule>

在API文档中，他们为Java提供了发送和接收响应的示例代码，它也在我的本地环境中工作。 Java代码段如下。

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);
        }
    }
}

上面的Java程序重新调整令牌没有问题。 当我使用esb ule子时，出现以下API错误。 建立请求时我在犯什么错误。 如何获得API的成功响应？

{
  "ack": "Failure",
  "version": "1.0beta",
  "timestamp": "2016-03-09T10:35:16.000Z",
  "errorMessage": {
    "message": "Cannot determine what type of request you are making. Often this can be the result of data that has not been escaped before being passed to the API. If you are passing data with quotation marks or other special characters, you should translate it to JSON, then escape it, before sending it over the API."
  }
}

解决您的问题意味着执行调试步骤。 我将带您了解他们。

假设：接收服务可能被Mule发送的一些额外报头弄糊涂了吗？

请尝试以下操作：

• 将Mule请求发送到http://requestb.in/，并仔细查看其结构。
• 然后从Java向api.bonanza.com发送相同的请求，它也会失败。
• 一点一点地删除多余的东西，直到它起作用。
• 然后回到Mule并通过调整发送的标头并修复所有其他差异来确保它创建了相同的请求...
