我正在尝试访问URL的微服务。设置了授权和内容类型的标题。 NPM运行正常。
使用curl使用Authorization标头访问相同的URL也会得到结果。但是我在通过完整代码访问URL时遇到此错误。
"message":"3. Error while making request - Error: tunneling socket could not be established, cause=connect EINVAL 0.0.12.56:80 - Local (0.0.0.0:0)","level":"error"}
代码使用request-promise-native模块
const request = require('request-promise-native')
const logger = require(process.env.APP_SERVICES_DIR + 'logger');
function getRequestAPI(task) {
console.log(`Basic ${Buffer.from(
`${process.env.USERNAME}:${process.env.PASSWORD}`
).toString('base64')}`);
return {
url: getQueryForTask(task),
headers: {
Authorization: `Basic ${Buffer.from(
`${process.env.USERNAME}:${process.env.PASSWORD}`
).toString('base64')}`,
'Content-Type': 'application/json'
},
resolveWithFullResponse: true
};
}
function makePortalRequest(task) {
logger.info(`Making request for task ${task.task_key}`);
return request(getRequestAPI(task))
.then(response => {
// logger.info('Response received');
console.log("get request API" );
try {
const responseBody = JSON.parse(response.body);
// Parse result and store
return parseResultAndStore(responseBody, task).then(() => {
return {
success: true
};
});
} catch (e) {
logger.error(
`Fetch Task: Error in parsing response from portal - ${e.message}`,
e
);
return {
success: false,
message: e.message
};
}
})
.catch(e => {
let errResponse = e.response || e.message;
if (errResponse.body) {
let responseBody = '';
// wrap JSON parse in try catch
try {
responseBody = JSON.parse(errResponse.body);
errResponse = `${
errResponse.statusMessage
} : ${responseBody.errorMessages.toString()}`;
logger.error(`1. Error while making request - ${errResponse}`);
} catch (e) {
// if JSON parse fails log the string
logger.error(
`2. Error while making request - ${errResponse.body}`
);
errResponse = errResponse.body;
}
} else {
logger.error(`3. Error while making request - ${errResponse}`);
}
return {
success: false,
message: errResponse
};
});
}
此服务在docker容器中运行。服务组件由docker-compose文件描述,并且所有环境变量均已适当设置。通过运行以下命令,我可以在docker容器中打开bash。
docker-compose exec run service-name bash
curl命令能够从docker bash内部访问URL。
curl -X GET 'https://url-to-fetch/?params=xyz' -H 'Authorization: Basic aDEwMjZzNzpXaXB0ZWxAMjAxOF8='
但是在运行的代码中,我无法从url获得输出响应。
"message":"3. Error while making request - Error: tunneling socket could not be established, cause=connect EINVAL 0.0.12.56:80 - Local (0.0.0.0:0)","level":"error"}
如何解决此问题?该错误的可能原因是什么?
