如何在解析云代码和客户端之间正确传递参数? (httpRequest示例) [英] How-to correctly pass params between Parse Cloud Code and the Client? (httpRequest Example)

问题描述

我已经看到了一些示例，阅读了文档并阅读了其他问题，但是我仍然不确定在何处添加/正确添加要在Cloud Code和我的客户端之间正确传递的参数.

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.

对于实例，这里我是通过我的云代码中的httpRequest创建一个新的类

在我的云代码中main.js

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()

});

在我的客户端

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)
        }
      });
    }

我的结果:

Bam！得到了正确的工作.现在说我想让我的网址成为传递的许多参数之一，我该怎么做呢?

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

推荐答案

当我问这个问题时，我也在修补某些事情，因为我无法正确传递任何东西(否则它将返回为空值)，所以这里有一个示例，说明如何将参数传递给它.

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.

在我的云代码main.js中

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"}
                 },

客户端

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

          success: function(result) {

结果:这应该已经正确传递了参数.再次使用标题"yourToken"忽略我，您不应该那样存储令牌.

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

这花了一段时间，我希望这可以对某人有所帮助.

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