javascript - 如何为工作海报 REST 调用定义 MFP javascript 适配器？

Question

我想编写一个与 Web 服务器通信的 MFP 适配器 (v8)。服务器等待包含图像信息的参数图像。移动客户端实现是在 ionic cordova 中实现的。

首先，我检查了海报，这是要发送的正确请求，但我无法找到适配器的正确配置/实现/调用。

我做错了什么？

1) 这是海报调用的工作副本

POST /GetImageKeywords HTTP/1.1
Host: XXXXXXX.mybluemix.net:443
Cache-Control: no-cache
Postman-Token: a98cac04-fe12-3e0f-2884-250bb5ff39ae
Content-Type: application/x-www-form-urlencoded

image=data%3..................

2) 这是不工作的 MFP 适配器实现:

function getTagsForPicture(urlimage) {
 var input = {
    method : 'post',
    returnedContentType : 'xml',
    path : 'GetImageKeywords',
  parameters: {'image': urlimage },
  headers: {"Accept":"application\/x-www-form-urlencoded",
            "Content-Type":"application\/x-www-form-urlencoded"}
 };
 return MPF.Server.invokeHttp(input);
}

3) 这是移动客户端适配器调用:

var getTagsRequest = new WLResourceRequest(
              "/adapters/UploadPic/getTagsForPicture",
              WLResourceRequest.POST);

              getTagsRequest.setQueryParameter("params", "['image']" );
              getTagsRequest.send().then(
                  getTagsSuccess,
                  getTagsFailure
              );

           function getTagsSuccess (result){
                console.log('Success, getTags is : ', result);
                q.resolve(result);
                WL.SimpleDialog.show(
                      "Got Tags", "You can continue using the application",
                      [{text: "OK, thanks", handler: function() {WL.Logger.debug("Got Tags"); }
                      }]
                );             
           };

           function getTagsFailure (result){
                console.log('Failure, getTags is : ', result);
                q.reject(result);
                WL.SimpleDialog.show(
                        "Got NO Tags", "Try it again later.",
                              [{text: "OK, thanks", handler: function() {WL.Logger.debug("Got NO Tags"); }
                              }]
           ); 
           }
           console.log("Tags*** ", q);
           return q.promise;

我有一个拼写错误MPF，我找到了配置的解决方案:

这是 javascript 适配器的工作实现:

function getTagsForPicture(urlimage) {
   var value = "image=" + urlimage;
   MFP.Logger.warn("Image input " + value.toString());
   var requestStructure = {
        method : 'post',
        returnedContentType : 'xml',
        path : 'GetImageKeywords',
      parameters: {'image': urlimage },
      headers: {"Accept":"application\/plain"}
     };
   MFP.Logger.warn("Preparing request structure " + JSON.stringify(requestStructure));
   return MFP.Server.invokeHttp(requestStructure);
 }

客户端内部出现与("params", "['image']")相关的错误，正确的是("params", [image])强>.

var getTagsRequest = new WLResourceRequest(
              "/adapters/UploadPic/getTagsForPicture",
              WLResourceRequest.POST);

              getTagsRequest.setQueryParameter("params", [image] );
              getTagsRequest.send().then(
                  getTagsSuccess,
                  getTagsFailure
              );

           function getTagsSuccess (result){
                console.log('Success, getTags is : ', result);
                q.resolve(result);
                WL.SimpleDialog.show(
                      "Got Tags", "You can continue using the application",
                      [{text: "OK, thanks", handler: function() {WL.Logger.debug("Got Tags"); }
                      }]
                );             
           };

           function getTagsFailure (result){
                console.log('Failure, getTags is : ', result);
                q.reject(result);
                WL.SimpleDialog.show(
                        "Got NO Tags", "Try it again later.",
                              [{text: "OK, thanks", handler: function() {WL.Logger.debug("Got NO Tags"); }
                              }]
           ); 
           }
