How-to correctly pass params between Parse Cloud Code and the Client? (httpRequest Example)

问题

I've seen some examples, read the docs and read other question however I'm still not quite sure where to add/properly add params to be passed between Cloud Code and my Client side correctly.

For Instance, Here I am creating a new class from a httpRequest in my Cloud Code

In my Cloud Code main.js

Parse.Cloud.define("POSTfromCloud", function(request, response) {

   //runs when Parse.Cloud.run("POSTfromCloud") on the client side is called
   Parse.Cloud.httpRequest({
        method: "POST",
        headers: {
          "X-Parse-Application-Id": "[PARSE_APP_ID]",
          "X-Parse-REST-API-Key": "[PARSE_REST_ID]",
          "Content-Type": "application/json"
       },

       //adds a new class to my parse data
       url: "https://api.parse.com/1/classes/newPOSTfromCloudClass/",


       body: {
               "newPOSTfromCloudClass": {"key1":"value1","key2":"value2"}
             },

       success: function (httpResponse) {
                console.log(httpResponse.text);
                response.success(httpResponse);
       },
       error:function (httpResponse) {
                console.error('Request failed with response code ' + httpResponse.status);
                response.error(httpResponse.status);
       }

    });  //end of Parse.Cloud.httpRequest()

});

on my client side

Parse.Cloud.run('POSTfromCloud', {}, {
        success: function(result) {
          console.log("Posted a new Parse Class from Cloud Code Successfully! :"+ JSON.stringify(result))
        },
        error: function(error) {
        console.log("Oops! Couldn't POST from Cloud Code successfully..  :"+ error)
        }
      });
    }

My Result:

Bam! Got that working correctly. Now lets say I want to make my url one of many parameters passed how do I do this?

回答1:

As I was asking this I was also tinkering with some things because I coundn't get anything to pass correctly (or it would return as an empty value) so here I have and example on how I can pass parameters into this.

in my cloudcode main.js

Parse.Cloud.define("POSTfromCloud", function(request, response) {

         //HERE- make a new instance of 'myValue' for Cloudcode to handle
         var myValue = request.params.myValue;

       Parse.Cloud.httpRequest({
            method: "POST",
....[blah blah]

            //AND HERE- placed that here in my body, **note:** you shouldnt store tokens like this, ignore what I named it
            body: {
                   "newPOSTfromCloudClass": {"yourToken":myValue,"key2":"value2"}
                 },

client side

      var myvalue = "I'm The VALUE";
      Parse.Cloud.run('POSTfromCloud', {myValue: myvalue}, {

          success: function(result) {

Result: this should have passed the param correctly. Again ignore me using the title "yourToken", you shouldn't be storing tokens like that.

This took a while to put together, I hope this can help someone.
