问题
I am trying to perform a simple push traces operation to my Google Cloud Trace project and I simply can't seem to send data across.
Here is my build.gradle file:
apply plugin: 'java'
repositories {
mavenCentral()
}
dependencies {
compile 'com.google.oauth-client:google-oauth-client-java6:1.20.0'
compile 'com.google.apis:google-api-services-cloudtrace:v1-rev6-1.22.0'
}
jar {
from configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
}
And the following Java code with dummy info for the project ID and my secrets file:
package test;
import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.client.googleapis.javanet.GoogleNetHttpTransport;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.json.JsonFactory;
import com.google.api.client.json.jackson2.JacksonFactory;
import com.google.api.services.cloudtrace.v1.CloudTrace;
import com.google.api.services.cloudtrace.v1.CloudTraceScopes;
import com.google.api.services.cloudtrace.v1.model.Trace;
import com.google.api.services.cloudtrace.v1.model.TraceSpan;
import com.google.api.services.cloudtrace.v1.model.Traces;
import java.io.FileInputStream;
import java.io.IOException;
import java.security.GeneralSecurityException;
import java.time.Instant;
import java.util.Collections;
public class Test {
public static void main(String[] args) throws IOException, GeneralSecurityException {
HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
GoogleCredential cred = GoogleCredential
.fromStream(
new FileInputStream("/path/to/secrets.json"),
httpTransport,
jsonFactory)
.createScoped(Collections.singletonList(CloudTraceScopes.TRACE_APPEND));
CloudTrace gceTrace = new CloudTrace.Builder(httpTransport, jsonFactory, cred)
.setApplicationName("Google Cloud Trace test app")
.build();
TraceSpan span1 = new TraceSpan();
span1.setName("test");
span1.setStartTime(Long.toString(Instant.now().toEpochMilli()*1000000)+"Z");
Trace trace = new Trace();
trace.setSpans(Collections.singletonList(span1));
Traces traces = new Traces();
traces.setTraces(Collections.singletonList(trace));
gceTrace.projects().patchTraces("myprojectid", traces).execute();
}
}
I currently get the following error that contains no helpful indication except something seems to be wrong with my startTime value:
Exception in thread "main" com.google.api.client.googleapis.json.GoogleJsonResponseException: 400 Bad Request

"code" : 400,

I have tried to replace the startTime with the following value:
span1.setStartTime("2016-08-04T01:00:00Z");
which gives me:
Exception in thread "main" com.google.api.client.googleapis.json.GoogleJsonResponseException: 400 Bad Request

"code" : 400,

at test.Test.main(Test.java:44)
I also tried adding a endTime with:
span1.setEndTime("2016-08-04T01:00:01Z");
which also gives me the same error.
I'm pretty much at a lost at what needs to be done as I cannot find a single working Java example for this. Thank you in advance for any pointers for a working solution.

Finally figured it out. Here's a working example with mandatory and optional fields pointed out.
build.gradle
apply plugin: 'java'
repositories {
mavenCentral()
}
dependencies {
compile 'com.google.oauth-client:google-oauth-client-java6:1.20.0'
compile 'com.google.apis:google-api-services-cloudtrace:v1-rev6-1.22.0'
}
jar {
from configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
}
Test.java
package test;
import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.client.googleapis.javanet.GoogleNetHttpTransport;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.json.JsonFactory;
import com.google.api.client.json.jackson2.JacksonFactory;
import com.google.api.services.cloudtrace.v1.CloudTrace;
import com.google.api.services.cloudtrace.v1.CloudTraceScopes;
import com.google.api.services.cloudtrace.v1.model.Trace;
import com.google.api.services.cloudtrace.v1.model.TraceSpan;
import com.google.api.services.cloudtrace.v1.model.Traces;
import java.io.FileInputStream;
import java.io.IOException;
import java.math.BigInteger;
import java.security.GeneralSecurityException;
import java.util.Collections;
import java.util.HashMap;
import java.util.Map;
public class Test {
public static void main(String[] args) throws IOException, GeneralSecurityException {
HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
GoogleCredential cred = GoogleCredential
.fromStream(
new FileInputStream("/path/to/secrets.json"),
httpTransport,
jsonFactory)
.createScoped(Collections.singletonList(CloudTraceScopes.TRACE_APPEND));
CloudTrace gceTrace = new CloudTrace.Builder(httpTransport, jsonFactory, cred)
.setApplicationName("Google Cloud Trace test app")
.build();
// They are optional
Map<String, String> labels = new HashMap<>();
labels.put("key1", "val1");
TraceSpan span = new TraceSpan();
span.setSpanId(new BigInteger("1")); // Mandatory
span.setName("test"); // Optional
span.setKind("RPC_SERVER"); // Optional
span.setStartTime("2016-08-04T01:00:00Z"); // Optional
span.setEndTime("2016-08-04T01:00:01Z"); // Optional
span.setLabels(labels); // Optional
Trace trace = new Trace();
trace.setProjectId("myprojectid"); // Mandatory
trace.setTraceId("A096D4956A424EEB98AE7863505B1E1F"); // Mandatory
trace.setSpans(Collections.singletonList(span)); // Mandatory
Traces traces = new Traces();
traces.setTraces(Collections.singletonList(trace)); // Mandatory
gceTrace.projects().patchTraces("myprojectid", traces).execute();
}
}
While some values are optional, like startTime or endTime, it makes sense to put something there.
I managed to put it together thanks to this question showing the expected values and looking at the REST API doc describing each field, especially for cryptic values like Trace ID:
- patchTraces()
- Trace and TraceSpan
