我正在使用 nodejs 和 REST API 与 bigquery 进行交互。我正在使用 google-oauth-jwt 模块进行 JWT 签名。
我授予了服务帐户写入权限。到目前为止,我可以列出项目、列出数据集、创建表和删除表。但是在通过多部分 POST 上传文件时,我遇到了两个问题:
- gzipped json 文件不起作用,我收到一条错误消息,提示“缺少结束边界”
- 当我使用未压缩的 json 文件时,我收到 401 未经授权的错误
我不认为这与我的机器时间不同步有关,因为其他 REST api 调用按预期工作。
var url = 'https://www.googleapis.com/upload/bigquery/v2/projects/' + projectId + '/jobs';
var request = googleOauthJWT.requestWithJWT();
var jobResource = {
jobReference: {
projectId: projectId,
jobId: jobId
},
configuration: {
load: {
sourceFormat: 'NEWLINE_DELIMITED_JSON',
destinationTable: {
projectId: projectId,
datasetId: datasetId,
tableId: tableId
},
createDisposition: '',
writeDisposition: ''
}
}
};
request(
{
url: url,
method: 'POST',
jwt: jwtParams,
headers: {
'Content-Type': 'multipart/related'
},
qs: {
uploadType: 'multipart'
},
multipart: [
{
'Content-Type':'application/json; charset=UTF-8',
body: JSON.stringify(jobResource)
},
{
'Content-Type':'application/octet-stream',
body: fileBuffer.toString()
}
]
},
function(err, response, body) {
console.log(JSON.parse(body).selfLink);
}
);
任何人都可以对此有所了解吗?
PS关于bigquery REST api的文档在很多方面都不是最新的,希望谷歌的人可以保持更新
