[英]NodeJS - ERR_INVALID_ARG_TYPE Error thrown while issuing a HTTP request to remote host
Recently, I encountered a problem while trying to issue a request using NodeJS and request-promise .最近,我在尝试使用 NodeJS 和request-promise发出请求时遇到了一个问题。
The following code is nested inside a multer call for file uploading (using nested functions / clusters.以下代码嵌套在用于文件上传的 multer 调用中(使用嵌套函数/集群。
const options = {
method: 'POST',
uri: 'URL of your choice',
body: {
//Body of the request
},
// json: true,
headers: {
// 'Content-Type': 'application/x-www-form-urlencoded',
},
}
request(options)
.then(function (response) {
console.log('Response: ', response);
})
.catch(function (err) {
console.log('Error: ', err);
});
While using the current request, without the 'json: true' property (commented out), I get the following error:在使用当前请求时,如果没有 'json: true' 属性(注释掉),我收到以下错误:
TypeError [ERR_INVALID_ARG_TYPE]: The first argument must be one of type string or Buffer. Received type object
at write_ (_http_outgoing.js:603:11)
at ClientRequest.write (_http_outgoing.js:575:10)
at Request.write (PATH/node_modules/request/request.js:1500:27)
at end (PATH/node_modules/request/request.js:549:18)
at Immediate.<anonymous> (PATH/node_modules/request/request.js:578:7)

at tryOnImmediate (timers.js:667:5)
at processImmediate (timers.js:649:5)
at process.topLevelDomainCallback (domain.js:121:23)
And when I turn the 'json: true' option on, the problem doesn't occur, but the remote API returns an error as it doesn't handle JSON requests/their added curly braces well.当我打开 'json: true' 选项时,问题不会发生,但远程 API 返回错误,因为它不能很好地处理 JSON 请求/他们添加的花括号。
Any ideas about getting over this issue?关于克服这个问题的任何想法?
Thank you.谢谢你。
Solved it!解决了!
As the remote host doesn't handle JSON well, and required "ordinary" POST request to be sent, I looked again inside request-promise's documentation.由于远程主机不能很好地处理 JSON,并且需要发送“普通”POST 请求,我再次查看了 request-promise 的文档。 By changing body{}
to formData{}
, and commenting out json: true
, the problem was solved.通过将body{}
更改为formData{}
,并注释掉json: true
,问题就解决了。
const options = {
method: 'POST',
uri: 'URL of your choice',
formData: {
//Request's data
},
}
request(options)
.then(function (response) {
console.log('Response: ', response);
})
.catch(function (err) {
console.log('Error: ', err);
});
Try Below -试试下面 -
url = "your url"
const options = {
url: url,
method: 'POST',
headers: {
Accept: 'application/json',
'Accept-Charset': 'utf-8'
},
body: {
}
};
request.post(options, function (err, response, body) {
// do something with your data
console.log(response.statusCode);
console.log(body)
});
我遇到了类似的问题,就我而言,上传目录未正确定义,请确保您要上传文件的路径存在且已明确定义
