GET 请求响应 express.js

如何解决GET 请求响应 express.js

我正在尝试将 GET 请求发送到我的快速服务器并使用

将其记录到控制台

const get = document.getElementById("getData");
      get.addEventListener('click',getData)
      
const myRequest = new Request('/url here/',{
  method: 'GET',});

function getData () { fetch(myRequest)
  .then(response => console.log(response))
  };

但是得到这个（下面）作为结果而不是预期的猫鼬数据库数组。我错过了什么？

Response {type: "basic",url: "url here",redirected: false,status: 200,ok: true, …}body: (...)bodyUsed: falseheaders: Headers {}ok: trueredirected: falsestatus: 200statusText: ""type: "basic"url: "url here/"__proto__: ResponsearrayBuffer: ƒ arrayBuffer()blob: ƒ blob()arguments: (...)caller: (...)length: 0name: "blob"__proto__: ƒ ()[[Scopes]]: Scopes[0]body: (...)bodyUsed: (...)clone: ƒ clone()formData: ƒ formData()headers: (...)json: ƒ json()ok: (...)redirected: (...)status: (...)statusText: (...)text: ƒ text()type: (...)url: (...)constructor: ƒ Response()Symbol(Symbol.toStringTag): "Response"get body: ƒ body()get bodyUsed: ƒ bodyUsed()get headers: ƒ headers()get ok: ƒ ok()get redirected: ƒ redirected()get status: ƒ status()get statusText: ƒ statusText()get type: ƒ type()get url: ƒ url()__proto__: Object

路线如下：

router.route('/').get((req,res) => {
  variable.find()
    .then(variable => res.json(variable))
    .catch(err => res.status(400).json('Error: ' + err));
});```

解决方法

你只需要使用 response.json() 来获取数据

#include <iostream>
#include <cstdlib>

#include <windows.h>

// Moves cursor by (DeltaX,DeltaY) = (offx,offy) relative to current position.
inline bool WinMoveCursor(int offx,int offy) {
    HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
    CONSOLE_SCREEN_BUFFER_INFO cbsi = {};
    if (!GetConsoleScreenBufferInfo(hConsole,&cbsi))
        return false;
    COORD coord = cbsi.dwCursorPosition;
    coord.X += offx;
    coord.Y += offy;
    if (!SetConsoleCursorPosition(hConsole,coord))
        return false;
    return true;
}

static void ClearLines(size_t cnt,size_t width = 40) { // Clears cnt last lines.
    std::cout << "\r";
    for (size_t i = 0; i < cnt; ++i) {
        for (size_t j = 0; j < width; ++j)
            std::cout << " ";
        std::cout << "\r";
        if (i + 1 < cnt)
            WinMoveCursor(0,-1); // Move cursor one line up,WinAPI.
    }
}

int main() {
    SetConsoleOutputCP(65001); // Enable UTF-8 if needed.

    bool good = false;
    char buy = 0;
    std::cout << "Enter number:" << std::endl;
    while (!good) {
        std::cin >> buy;
        switch (buy) {
            case '1': {
                std::cout << "Valid number." << std::endl;
                good = true;
                break;
            }
            default: {
                std::cout << "Sorry thats not a valid number!\n";
                std::system("pause");
                ClearLines(4);
                break;
            }
        }
    }
}
