语法错误：JSON.parse 处的 JSON 输入意外结束（<anonymous> ) on(&quot;数据&quot;)

Question

我尝试使用其他 api 并且它有效，但是它不适用于这个。

const express = require("express");
const https = require("https");
const bodyParser = require("body-parser");

const app = express();

app.use(bodyParser.urlencoded({extended:true}));
app.use(bodyParser.json());
app.get("/",(req, res)=>{
https.get("https://pixabay.com/api/?key=xxx-zzz&q=yellow+flowers&image_type=photo", (response)=>{
   console.log(response.statusCode);
       response.on("data",d=>{
           const lala = JSON.parse(d);
           console.log(lala);
       })
    
    })
});
app.listen(3000,()=>{
    console.log("Server started on port 3000")
})

我在控制台中得到了这个

200
未定义：1
{"total":28739,"totalHits":500,"hits":[{"id":3063284,"pageURL":"https://pixabay.com/photos/rose-flower-petal-floral-noble- 3063284/","type":"photo","tags":"rose,flower,petal","previewURL":"https://cdn.pixabay.com/photo/2018/01/05/16/24 /rose-3063284_150.jpg","previewWidth":150,"previewHeight":99,"webformatURL":"https://pixaba

语法错误：JSON 输入意外结束
在 JSON.parse()

Answer 1

data事件并不意味着请求已经完成。 请求数据以数据包的形式发送。

使用data事件收集所有数据，然后在与数据交互之前将其合并到end事件中：

const express = require("express");
const https = require("https");
const bodyParser = require("body-parser");

const app = express();

app.use(bodyParser.urlencoded({extended:true}));
app.use(bodyParser.json());
app.get("/",(req, res)=>{
https.get("https://pixabay.com/api/?key=xxx-zzz&q=yellow+flowers&image_type=photo", (response)=>{
   console.log(response.statusCode);
       let chunks = [];
       response.on("data",d=>{
           chunks.push(d);
       });
       response.on("end",()=>{
           const lala = JSON.parse(Buffer.concat(chunks).toString('utf8'));
           console.log(lala);
       });
    });
});
app.listen(3000,()=>{
    console.log("Server started on port 3000");
});
