无法将 JSON 数据发布到 REST 服务器

Question

我正在尝试将一些数据发布到通过 Hyperledger composer 生成的 REST 服务器中。我有一个 JSON 文件，我正在尝试使用 NodeJS 和请求模块来发布。但是，请求模块似乎可以找到我的链接。

这是我试图发布我的资产的地方（这是在 REST 服务器上）：

我将这个帖子部分的 url 复制并粘贴到我的 inputter.js 代码中

这是我当前的目录（我正在运行 inputter.js 文件）：

这是我的 inputter.js 代码：

var request = require('request');
var requestData = require("./input.json");


var url = "http://localhost:3000/explorer/#!/models95certificateModel95certificate/models_certificateModel_certificate_create";

request({
    url: url,
    method: "POST",
    headers: {
        "content-type": "application/json",
        },
    json: requestData
    }, function (error, response, body) {
        if(error)
            throw error;
        console.log('statusCode:', response && response.statusCode);
        console.log('body:', body);
    });

这是我要输入的 JSON 数据：

[ 
    { 
        "$class": "models.certificateModel.certificate",
        "hash" : "36ba3cf8261e1d203eafcf102f6426a9f0ff38edc62df6d7359938b2f358d68b8ce568325ebcd1ddfb3f64ebe41b73fc84d8fecd9023f834b487738ae02c6370",
        "state": "VALID",
        "issuer": "45576f7f-2f07-43f7-9638-1dcaa37a9f94",
        "owner": "d804d827-ebe8-4c42-b4b3-2888bba676a8",
        "comments": "Issued Certificate"
    },
    { 
        "$class": "models.certificateModel.certificate",
        "hash": "fc8ab6b4f10c80fbf6219e91991a32708f2da3d6de6eb2a52ac78ca930293597fdc693533afee6caae501a4808ecbb3b5367383e5e2ab88b08aef15af61a6497",
        "issuer": "45576f7f-2f07-43f7-9638-1dcaa37a9f94",
        "owner": "d2f0cf4b-cb21-4bc8-b059-e83abaa13e60",
        "state": "VALID",
        "comments": "Issued Certificate"
    },
    { 
        "$class": "models.certificateModel.certificate",
        "hash": "c876cf2b110f3af71fba5bba6dd48d2a063f1806c307cd9ae3e50494d39847137eba464c81bb423342bac8b6084f3e900b85044bef3cec459fd10c5f6bea0ad5",
        "issuer": "45576f7f-2f07-43f7-9638-1dcaa37a9f94",
        "owner": "39dfa2eb-76b9-44e4-a9fa-a107fadd2d46",
        "state": "VALID",
        "comments": "Issued Certificate"
    } 
]

我在 REST 服务器上手动输入了数据，JSON 文件中的所有内容似乎都是有效的。

但是，当我运行 inputter.js 应用程序时，我收到 404 错误。这是错误的正文：

   { statusCode: 404,

     message: 'Cannot POST /explorer/',

我对请求模块相对较新，无法弄清楚这里到底发生了什么。请求模块不能读取本地主机地址吗？我到底错过了什么？

我认为您没有导出输入数据。
