我正在尝试使用谷歌视觉的一个功能,即文本检测。但当我碰到那个api时,我就会得到这个错误。我仔细检查了网址和其他数据。
{ Error: getaddrinfo ENOTFOUND https://vision.googleapis.com/v1/images:annotate?key=<> https://vision.googleapis.
com/v1/images:annotate?key=<key>:80
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:56:26)
errno: 'ENOTFOUND',
code: 'ENOTFOUND',
syscall: 'getaddrinfo',
hostname:
'https://vision.googleapis.com/v1/images:annotate?key=<key>',
host:
'https://vision.googleapis.com/v1/images:annotate?key=<key>',
port: 80 }
最佳答案
这段代码应该可以工作,只需要进行一些更改,例如我们将使用https模块而不是http模块。
const https = require('https');
const options = {
hostname: 'vision.googleapis.com',
path: '/v1/images:annotate?key=' + API_KEY,
method: 'POST',
headers: {
'Content-Type' : 'application/json'
}
};
let data = "";
const req = https.request(options, (res: any) => {
res.on('data', (chunk: any) => {
data += chunk;
});
res.on('end', (chunk) => {
console.log(`BODY: ${data}`);
});
});
req.on('error', (e) => {
console.log(e)
console.error(`problem with request: ${e.message}`);
});
// Write data to request body
req.write(JSON.stringify(body))
req.end()
