Question

我尝试通过Go应用程序从现有模板启动Dataflow作业。

到目前为止，我已带来了CreateJobFromTemplateRequest并创建了一份包含工作信息的Try it this will work definitely: Let's take a sample example: For example, create a sample table CREATE TABLE bob ( empno VARCHAR2(10) NOT NULL, ename VARCHAR2(15) NOT NULL, ssn VARCHAR2(10) NOT NULL); Insert data into that table Insert into bob ( empno,ename,ssn) values ('abC0123458','zXe5378023','0pl4783202'); Insert into bob ( empno,ename,ssn) values ('0123abcdef','a12dldfddd','Rns0101010'); Query to select the all the columns select * from bob where length(trim(translate(substr(empno,1,3),'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ',' '))) IS NULL AND length(trim(translate(substr(empno,4,4),'0123456789',' '))) IS NULL; To do the same thing on multiple columns use union operator select * from bob where length(trim(translate(substr(empno,1,3),'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ',' '))) IS NULL AND length(trim(translate(substr(empno,4,4),'0123456789',' '))) IS NULL; union select * from bob where length(trim(translate(substr(ename,1,3),'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ',' '))) IS NULL AND length(trim(translate(substr(ename,4,4),'0123456789',' '))) IS NULL;。

我现在如何使用Compute Engine中的内置服务帐户凭据执行该请求？

仅在为您正在呼叫的服务开发Auto-generated Google APIs for Go时才建议使用Google Client Library for Go。 Dataflow还没有客户端库。

使用默认凭据从Go应用启动数据流模板：

ctx := context.Background()
oauthClient, err := google.DefaultClient(ctx, dataflow.CloudPlatformScope)

dataflowService, err := dataflow.New(oauthClient)

if err != nil {
  panic(err)
}

templateRequest := dataflow.CreateJobFromTemplateRequest{
  GcsPath: "gcs path to template here",
  JobName: "choose a unique job name here",
  Parameters: map[string]string{
    "parameters": "for job",
  },
}

result, err := dataflowService.Projects.Templates.Create("project id", &templateRequest).Do()

if err != nil {
  panic(err)
}
