我不能 post 使用请求承诺

Question

我的问题是我收到一条错误消息，告诉我无法发出 post 请求。我使用 insertDocuments 函数将消息插入数据库。我正在尝试制作 'mongolab-data-api' node.js 模块的面向承诺的版本。如果我的问题令人困惑，我深表歉意

//This is a function in a class that handles all mlab related things
var rp = require('request-promise')
var insertDocuments = options => {
    if (!options.database || !options.collectionName || !options.documents) throw new Error('Database name, Collection Name, and Document(s) are required')
    var opt = {
        uri: `https://api.mongolab.com/api/1/databases/${options.database}/collections`,
        qs: {
            apiKey: this.apiKey

        },
        method: 'POST',
        body: {
            documents: options.documents
        },
        headers: {
            'User-Agent': 'Request-Promise'
        },
        json: true // Automatically parses the JSON string in the response
    };
    return rp(opt)
}

var options = {
    database: 'lexybase',
    collectionName: 'evy-history',
    documents: msg
}
insertDocuments(options)

我收到此错误：未处理的拒绝 StatusCodeError: 405 - {"message":"POST not allowed."}

编辑：事实证明，问题是 collectionName 需要指定，它应该是

body:  options.documents

而不是

body: {
    documents:options.documents
}

Answer 1

您在 uri 中缺少集合名称:

uri: https://api.mongolab.com/api/1/databases/${options.database}/collections

应该是：

uri: https://api.mongolab.com/api/1/databases/${options.database}/collections/{collectionName}

只需更改 collectionName
