Axios Post请求给出错误400，错误请求

Question

我正在为一个项目使用Hackerrank API。查看官方文档，点击这里！

在他们的网站上有一个使用UNIREST的例子，

unirest.post("https://hackerrank-hackerrank.p.rapidapi.com/https://api.hackerrank.com/checker/submission.json")
.header("X-RapidAPI-Host", "hackerrank-hackerrank.p.rapidapi.com")
.header("X-RapidAPI-Key", "a72a0f1b5dmshdc3f55e233876eap1b8939jsnffad2a5b6e6e")
.header("Content-Type", "application/x-www-form-urlencoded")
.send("callback_url=https://mywebsite.com/responseHandler")
.send("source=puts 'Hello World'")
.send("lang=8")
.send("testcases=["This is input 1", "This is input 2"]")
.send("wait=false")
.send("format=json")
.end(function (result) {
  console.log(result.status, result.headers, result.body);
});

由于我使用的是axios，所以我将其转换为类似的axios代码，如下所示：

var params =  {
            "callback_url": "https://mywebsite.com/responseHandler",
            "source": "puts 'Hello World'",
            "lang": 8,
            "testcases": "[\"This is input 1\", \"This is input 2\"]",
            "wait": false,
            "format": "json"
          }
        var config = {
            mode: "no-cors",
            headers: {
                "X-RapidAPI-Host": "hackerrank-hackerrank.p.rapidapi.com",
                "X-RapidAPI-Key": "a72a0f1b5dmshdc3f55e233876eap1b8939jsnffad2a5b6e6e",
                'Access-Control-Allow-Origin': '*',
                "Content-Type": "application/x-www-form-urlencoded"
            }
        }
        axios.post("https://hackerrank-hackerrank.p.rapidapi.com/https://api.hackerrank.com/checker/submission.json", params, config)
            .catch((error) => {
                console.log(error.message);
            })
            .then((response) => {
                console.log(response);
            })

我希望这只适用于示例中所示的示例，但它给我带来了以下错误：

请求失败，状态代码为400
错误：请求失败，状态代码为400
在createError（createError.js:16)
在sett(settle.js:18)
在xmlHttpRequest.handleLoad(xhr.js:77)
在createError（createError.js:16)
在settle（settle.js:18)
在xmlHttpRequest.handleLoad

我对此比较陌生，如果有人能指出我做错了什么，那会很有帮助的！

由于requestcontent-type是application/x-www-form-urlencoded，您应该将数据作为FromData传递

var data= new FormData(); // Currently empty
data.append('callback_url', 'https://mywebsite.com/responseHandler');
data.append('source', "puts 'Hello World'");
data.append('lang', '8');
data.append('testcases', "[\"This is input 1\", \"This is input 2\"]");
data.append('wait', false);
data.append('format', "json");
data.append('api_key', "<valid hackerrenk api key>"); // API KEY is mandatory

axios.post("https://hackerrank-hackerrank.p.rapidapi.com/https://api.hackerrank.com/checker/submission.json", data, config)
            .catch((error) => {
                console.log(error.message);
            })
            .then((response) => {
                console.log(response);
            })
