我正在尝试使用nodejs和请求 [2] 向Google QPX Express API [1]发出HTTP POST请求。
我的代码如下所示:
// create http request client to consume the QPX API
var request = require("request")
// JSON to be passed to the QPX Express API
var requestData = {
"request": {
"slice": [
{
"origin": "ZRH",
"destination": "DUS",
"date": "2014-12-02"
}
],
"passengers": {
"adultCount": 1,
"infantInLapCount": 0,
"infantInSeatCount": 0,
"childCount": 0,
"seniorCount": 0
},
"solutions": 2,
"refundable": false
}
}
// QPX REST API URL (I censored my api key)
url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=myApiKey"
// fire request
request({
url: url,
json: true,
multipart: {
chunked: false,
data: [
{
'content-type': 'application/json',
body: requestData
}
]
}
}, function (error, response, body) {
if (!error && response.statusCode === 200) {
console.log(body)
}
else {
console.log("error: " + error)
console.log("response.statusCode: " + response.statusCode)
console.log("response.statusText: " + response.statusText)
}
})
我想要做的是使用multipart参数[3]传递JSON。但是我没有正确的JSON响应,而是收到一个错误(未定义400)。
当我使用CURL使用相同的JSON和API密钥发出请求时,它可以正常工作。因此,我的API密钥或JSON没错。
我的代码有什么问题?
编辑:
工作的CURL示例:
i)我将传递给我的请求的JSON保存到名为“ request.json”的文件中:
{
"request": {
"slice": [
{
"origin": "ZRH",
"destination": "DUS",
"date": "2014-12-02"
}
],
"passengers": {
"adultCount": 1,
"infantInLapCount": 0,
"infantInSeatCount": 0,
"childCount": 0,
"seniorCount": 0
},
"solutions": 20,
"refundable": false
}
}
ii)然后,在终端中,我切换到新创建的request.json文件所在的目录并运行(myApiKey显然代表我的实际API密钥):
curl -d @request.json --header "Content-Type: application/json" https://www.googleapis.com/qpxExpress/v1/trips/search?key=myApiKey
