Question

是否可以直接将Swift中的PFFiles传递给Cloud Code并将其设置在对象上？

我有一个PFFile，

let imageData = UIImageJPEGRepresentation(self.imageView.image!, 0.1)
let imageFile = PFFile(data: imageData!)

我尝试将其设置在用户对象上，然后在云代码中进行签名，如下所示：

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

    var theimage = request.params.image
    var username = request.params.username
    var pw = request.params.password

    var user = new Parse.User();
    user.set("username", username);
    user.set("password", pw);

    theimage.save().then(function(){
        user.set("image",theimage)
        user.signUp(null, {
        success: function(user) {       
            response.error("working");
        },
        error: function(user, error) {
            response.error("Sorry! " + error.message);
        } });

    }, function(error) {
        response.error("Sorry! " + error.message);
    });

});

调用云代码的iOS代码：

 PFCloud.callFunctionInBackground("createNewUser", withParameters: 
 ["username": username, "password": password, "image": imageFile], 
 block: { (result, error) -> Void in
    // UI stuff
 })

我收到此错误：

TypeError: Cannot read property 'format' of undefined
at e.a.value (Parse.js:13:25673)
at main.js:40:14 (Code: 141, Version: 1.10.0)

我试着看看这个：http://parse.com/docs/js/api/classes/Parse.File.html我仍然不确定如何将我的图像从Swift转换为云代码，以便我可以注册新用户...

我没有将图像作为PFFile传递，而是将图像作为NSData传递，然后将结果转换为Parse.File对象。然后我保存了它并签了用户。效果很好！

JS

var parseFile = new Parse.File("prof",theimage)

parseFile.save().then(function(){
    user.set("image",parseFile)
    user.signUp(null, {
    success: function(user) {       
        response.success("working");
    },
    error: function(user, error) {
        response.error("Sorry! " + error.message);
    } });

}, function(error) {
    response.error("Sorry! " + error.message);
});

在Parse Cloud Code中设置对象的PFFile
