Node.js Axios POST请求是否采用application/x-www-form-urlencoded格式？

我正在尝试使用

axios

从Node.js向IBM Cloud发送此POST请求：

curl -k -X POST \
  --header "Content-Type: application/x-www-form-urlencoded" \
  --header "Accept: application/json" \
  --data-urlencode "grant_type=urn:ibm:params:oauth:grant-type:apikey" \
  --data-urlencode "apikey=s00pers3cret" \
  "https://iam.cloud.ibm.com/identity/token"

curl

请求有效。我很幸运地在另一个节点函数中使用了

axios

当使用

应用程序/x-www-form-urlencoded

格式数据时，系统会这样做：

const querystring=require（'querystring'）；
轴心柱http://something.com/stringify（{foo:'bar'}））；

我在信中写道：

const querystring=require（'querystring'）；
轴心柱https://iam.cloud.ibm.com/identity/token“，querystring.stringify({
grant_type:'urn:ibm:params:oauth:grant type:apike'，
apikey:'s00pers3cret'
})
)
.然后（功能（响应）{
console.log（response.data）；
})
.catch（error=>console.error（error））；

以下是完整的错误响应：

我还尝试：

const axios=require（'axios'）；
const querystring=require（'querystring'）；
axios({
方法：“post”，
网址：'https://iam.cloud.ibm.com/identity/token',
标题：{
contentType:'application/x-www-form-urlencoded'，
接受：'application/json'
},
数据：querystring.stringify({
grant_type:'urn:ibm:params:oauth:grant type:apike'，
apikey:'s00pers3cret'
})
})
.然后（功能（响应）{
console.log（response.data）；
})
.catch（error=>console.error（error））；

相同的错误响应。有什么建议吗？

授权类型值中缺少一个y，请将其更改为：

urn:ibm:params:oauth:grant-type:apikey

顺便说一下，这是一个来自IBM（而不是Axios）的与服务器相关的错误，您可以这样检查它们：

.catch(error => console.log(error.response.data));

grant_类型值中缺少y，请将其更改为：

urn:ibm:params:oauth:grant-type:apikey

顺便说一下，这是一个来自IBM（而不是Axios）的与服务器相关的错误，您可以这样检查它们：

.catch(error => console.log(error.response.data));
