在 http 请求连接器中传递动态查询参数和路径参数

Question

我希望将查询参数和路径参数列表传递给 http 请求 mule 连接器。进入此连接器的输入是一个 pojo 列表，其中包含查询和路径参数的值。

http 请求连接器如下所示：

<http:request config-ref="HTTP_Request_Configuration" path="/rates/api/v1/rates/{in}.csv" method="GET" doc:name="End_HTTP request">
<http:request-builder>
    <http:query-param paramName="api_key"
        value="abcde" />
    <http:query-param paramName="quote" value={target_currency} />
    <http:query-param paramName="date" value={date} />
    <http:query-param paramName="fields" value="averages" />
    <http:uri-param paramName="in" value={source_currency} />
</http:request-builder>

pojo 类如下所示：

public class Data {

    private String sourceCurrency;
    private String targetCurrency;
    private String date = (new SimpleDateFormat("yyyy-MM-dd")).format(new Date());

    public Data() {
    }

    public String getSourceCurrency() {
        return sourceCurrency;
    }

    public void setSourceCurrency(String sourceCurrency) {
        this.sourceCurrency = sourceCurrency;
    }

    public String getTargetCurrency() {
        return targetCurrency;
    }

    public void setTargetCurrency(String targetCurrency) {
        this.targetCurrency = targetCurrency;
    }

    public String getDate() {

        return date;
    }
}

如果http请求连接器的输入是Data类的对象，那么如何设置查询和路径参数。

有人可以帮我举个例子吗？

谢谢。

首先，您必须将对象 Data（即有效负载）的值分配给所需的变量（targetCurrency、date、sourceCurrency），然后您必须将变量的值分配给查询参数和路径参数。这里有一个例子：

    </flow>

这是我正在使用的课程：

package com.testing.domain;

import java.util.List;

public class GeneralRequest {
    private String processTypeJob;
    private String waitTime;
    private List<String> processIds;
    private String processTypeGroup;
    private List<JobConfiguration> jobConfigurations;

    public String getProcessTypeJob() {
        return processTypeJob;
    }
    public void setProcessTypeJob(String processTypeJob) {
        this.processTypeJob = processTypeJob;
    }
    public List<String> getProcessIds() {
        return processIds;
    }
    public void setProcessIds(List<String> processIds) {
        this.processIds = processIds;
    }
    public String getProcessTypeGroup() {
        return processTypeGroup;
    }
    public void setProcessTypeGroup(String processTypeGroup) {
        this.processTypeGroup = processTypeGroup;
    }
    public List<JobConfiguration> getJobConfigurations() {
        return jobConfigurations;
    }
    public void setJobConfigurations(List<JobConfiguration> jobConfigurations) {
        this.jobConfigurations = jobConfigurations;
    }
    public String getWaitTime() {
        return waitTime;
    }
    public void setWaitTime(String waitTime) {
        this.waitTime = waitTime;
    }



}

我认为您需要在流程中添加一个数据对象（一个流程变量）。然后您可以在请求生成器中使用该变量，例如 {flowVars.variable.someproperty}
