如何使用 javascript 适配器将 post 图像发送到服务器并获得 xml 结果？
How to use javascript adapter to post an image to a server and get xml result?
适配器以前工作正常，现在适配器不工作。
在我的本地机器上安装 Mobile Foundation 8.0 beta 并迁移到 MobileFirst Foundation 8.0 GA 版本。
.java 服务器 将图像发送到 alchemy 并且只是 returns alchemy xml 结果到 MobileFirst 适配器。
Android和iOS的Debug信息不一样，所以我都列出来了。
a) iOS 手机客户端:
iOS 上的信息与 android 上的信息不同。
XML adapter:
的 cordova mfp-pluging 实现中似乎存在 bug
因为适配器似乎期望在响应 json 结构中有一个 "responseJSON"，这就是我的想法，基于调试信息。
xCode 调试器自动显示的响应不包含 "responseJSON"，但它包含来自炼金术结果的所有有效值。
只需在 xCode 调试 输出中查看此处：

2. 1:"Failed to parse the payload from backend (procedure: getTagsForPicture)"
android 应用chrome 控制台中的完整错误信息:
当我检查服务器日志或海报中的 XML 时，我没有看到任何信息。
a) 海报 xml 结果：
b) .java 服务器登录 bluemix：
Apdater和MobileClient的实现：
a) 适配器代码：
function getTagsForPicture(urlimage) {
var value = "image=" + urlimage;
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);
}
b) cordova客户端代码：
var formParams = {"params":"['"+ image + "']"};
var getTagsRequest = new WLResourceRequest(
"/adapters/UploadPic/getTagsForPicture",
WLResourceRequest.POST);
console.log('>>> Image to get Tags formParams : ', formParams);
getTagsRequest.sendFormParameters(formParams);
getTagsRequest.send().then(
getTagsSuccess,
getTagsFailure
);
我认为问题与客户端中的代码有关：
var formParams = {"params":"['"+ image + "']"};
var getTagsRequest = new WLResourceRequest(
"/adapters/UploadPic/getTagsForPicture",
WLResourceRequest.POST);
console.log('>>> Image to get Tags formParams : ', formParams);
getTagsRequest.sendFormParameters(formParams);
getTagsRequest.send().then(
getTagsSuccess,
getTagsFailure
);
因为 getTagsRequest.sendFormParameters(formParams); 与 getTagsRequest.send().then 的作用相同。
我在代码中删除了 getTagsRequest.send() 和这个结果：
getTagsRequest.sendFormParameters(formParams);
getTagsRequest.send().then(
我更改了
中的代码后
sendRequest.sendFormParameters(formParams).send().then(
//sendRequest.send().then(
sendSuccess,
sendFailure
);
成功了。
