Question

我正在尝试与网关互动并想尝试https://www.npmjs.com/package/@types/request模块。

我正在尝试执行的代码：

export class OAuthAccessor {

    //some stuff

    public static createOAuthAccessToken() {
        this.makeCall();  //this line 11
    }

    private static makeCall() {
        var request = require('request');
        request.post({
            uri: "https://api.sandbox.paypal.com/v1/oauth2/token",
            headers: {
                "Accept": "application/json",
                "Accept-Language": "en_US",
                "content-type": "application/x-www-form-urlencoded"
            },
            auth: {
                'user': this.clientID,
                'pass': this.secret,
                // 'sendImmediately': false
            },
            form: {
                "grant_type": "client_credentials"
            }
        }, function(error, response, body) {
            console.log("error = " + error);
            console.log(body);
        });
    }

}

错误：

file：///.../OAuthAccessor.js：11：30：JS ERROR错误：无法找到模块＆＃39;请求＆＃39;。 Computed path＆＃39; /Users/admin/Library/Developer/CoreSimulator/Devices/ACA260DA-C0FD-4373-8822-447422199751/data/Containers/Bundle/Application/EE654C43-B629-4817-929F-F4E52DA1A99F/IPGIntegration.app /应用程序/ tns_modules /请求＆＃39;

            ]
        }
    },
    "exclude": [
        "node_modules",
        "platforms",
        "**/*.aot.ts"
    ]
}

我做了什么：使用打字稿模板

创建一个新项目

tns create my-app-name --template typescript
npm install typescript (version 2.3.4)
npm install @types/request

我已经尝试重新安装typescript和types / request模块以及node_modules文件夹，以及其他版本的typescript。我在安装该模块时是否遗漏了什么？

Answer 1

您不能使用request npm模块，因为它是一个nodeJS模块，具体取决于内置节点功能，如net模块。

为了发出http请求，您可以使用跨平台模块＆＃39; http实施，如NativeScript文档文章所示 - http://docs.nativescript.org/cookbook/http

如果您需要发出https请求，可以使用nativescript-https插件 - https://www.npmjs.com/package/nativescript-https

Answer 2

也许尝试

require('@types/request')

JS ERROR尝试执行简单的http请求时出错
