未捕获您必须使用 Parse.initialize 指定一个键

Question

我已经使用 Parse 大约三个月了，但已经开始使用一个新应用程序。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正在向数据库发出请求。该文件包含在 main.js 文件中。

当我尝试部署（使用 1.4.2 sdk）时出现错误：

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，则会收到错误消息：

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，它将上传，但如果没有注释，我会收到错误消息。我的另一个工作应用程序从不调用Parse.initialize。为什么现在要它？

Answer 1

我遇到了同样的问题，我发现每当我尝试在全局级别调用函数时都会遇到同样的错误。我唯一一次能够调用函数是在其他函数的范围内。

关于您的代码，我想您正在尝试导出函数本身，例如

exports.createSmsVerification = createSmsVerification;

你拥有的代码：

exports.createSmsVerification = createSmsVerification();

实际调用函数并导出结果。

Answer 2

这花了我大约 3/4 天的时间来找到答案。它不在文档中。错误一点都不清楚。

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

以下代码不起作用

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();

以下代码有效

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);
        });
}
