redirect - How do I send data from 1 api to another api using apigee

问题描述

I am recently started using apigee proxy.Please do not block me. I am using postman to post data into proxy. I have assigned a extract policy to extract some values from the json data like speed,latitude, longitude etc. Then I have used a assign policy to convert speed into gpsspeed etc as per client requirement. After that i use javascript policy to output if speed is higher > 50 then high or low. I am giving an example of the data. Now i want to forward the resultant data to another api.Maybe anything apigee offers for testing purpose.I want to see the data in the resultant api. I used service call out policy to send data to another url. I am attaching the policy.

 <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
 <ServiceCallout name="ServiceCallout-GeocodingRequest1">
 <DisplayName>Inline request message</DisplayName>
 <Request variable="callAnotherService">
    <Set>
        <Payload contentType="application/json">
          {response.content} // reading data from javascript policy
        </Payload>
    </Set>
</Request>
<Response>CalloutResponse</Response>
<Timeout>30000</Timeout>
<HTTPTargetConnection>
    <URL>http://httpbin.org/anything</URL>
</HTTPTargetConnection>

trace call I have attached a javascript policy before it. I am attaching the policy.

 var content = context.getVariable("response.content") //read the response
  content = JSON.parse(content); //parse into an object
  if (content.speed > 50) { //apply the condition
  content.speed = "high";
   }
  else {
  content.speed = "low";
  }
  context.setVariable("response.content", JSON.stringify(content)); //set it 
  back on the response

Can anyone help me how can i forward the data to another api? Is my procedure right?Is the procedure to extract variables from java script policy right?Please guide me.

解决方案

好的，如果你确定 setVarible 之后的值不为空，那么试试下面的代码。

注意：在您的 JavaScript 策略中，我在将值设置回它之后更改了变量名称（为了不混淆）。

var content = context.getVariable("response.content") //read the response
content = JSON.parse(content); //parse into an object
if(content.speed > 50){ 
    content.speed = "high";
}
else{
    content.speed = "low";
}
context.setVariable("serviceCalloutRequest", JSON.stringify(content)); //I have changed from "response.content" to "serviceCalloutRequest"

并在服务标注政策中尝试：

<Request clearPayload="true" variable="callAnotherService">
    <IgnoreUnresolvedVariables>false</IgnoreUnresolvedVariables>
    <Set>       
        <Payload variablePrefix="@" variableSuffix="#">@serviceCalloutRequest#</Payload>
        <Verb>POST</Verb>
    </Set>
</Request>

使用variablePrefix和variableSuffix来引用您在 javascript 策略中分配的值，在这种情况下，我指的是“serviceCalloutRequest”。
