Question

我已经使用Parse大约三个月但已经开始使用新的应用程序了。我正在使用Parse 1.4.2 js sdk。

我在一个单独的文件中有一些代码，它向数据库发出请求。该文件包含在main.js文件中。

当我尝试部署（使用1.4.2 sdk）时，我收到错误：

Uploading source files
Uploading recent changes to scripts...
The following files will be uploaded:
/Users/aaron/dev/Familiar/cloud/main.js
/Users/aaron/dev/Familiar/cloud/user.js
/Users/aaron/dev/Familiar/cloud/verification.js
Finished uploading files
Uncaught You must specify a key using Parse.initialize.

如果我尝试使用最新的sdk进行部署，我会收到错误：

Uploading source files
Uploading recent changes to scripts...
The following files will be uploaded:
/Users/aaron/dev/Familiar/cloud/verification.js
Finished uploading files
TypeError: Object #<Object> has no method 'request'

    at e.a.value (Parse.js:13:76)
    at e.<anonymous> (verification.js:18:38)

如果我注释掉所有verification.js它会上传，但如果没有注释，我会收到错误消息。我的其他工作应用从不致电Parse.initialize。为什么现在要求它？

Answer 1

我有同样的问题，我发现每当我尝试在全局级别调用函数时，我都会遇到同样的错误。我能够调用函数的唯一时间是在其他函数的范围内。

与您的代码有关，我想您正在尝试导出函数本身，例如

exports.createSmsVerification = createSmsVerification;

您拥有的代码：

exports.createSmsVerification = createSmsVerification();

实际调用该函数并导出结果。

Answer 2

这花了我大约3/4的时间来找到答案。它不在文档中。错误根本不明确。

问题似乎与export的使用方式有关。我假设使用exports.methodName = methodName()试图调用该方法，而不是将其设置为exports的属性。 exports.methodName = methodName也可以。

以下代码不工作

function createSmsVerification(user) {
    return getUserSmsVerification(user)
        .then(function (verification) {
            var verificationQuery = new Parse.Query("Verification");
            return verificationQuery.first(); <-- this is the line causing the error
        })
        .then(function (verification) {
            return verification;
        }, function (error) {
            return Parse.Promise.error("createSmsVerification - " + error.message);
        });
}
exports.createSmsVerification = createSmsVerification();

以下代码工作

exports.createSmsVerification = function(user) {
    return getUserSmsVerification(user)
        .then(function (verification) {
            var verificationQuery = new Parse.Query("Verification");
            return verificationQuery.first();
        })
        .then(function (verification) {
            return verification;
        }, function (error) {
            return Parse.Promise.error("createSmsVerification - " + error.message);
        });
}
