如何在 Java 中执行简单的 Google Cloud Trace 请求
How to do a simple Google Cloud Trace request in Java
我正在尝试对我的 Google Cloud Trace 项目执行简单的推送跟踪操作，但我似乎无法发送数据。
这是我的 build.gradle 文件：
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) }
}
以及以下 Java 代码，其中包含项目 ID 和我的机密文件的虚拟信息：
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();
}
}
我目前收到以下错误，除了我的 startTime 值似乎有问题外，没有任何有用的指示：
Exception in thread "main" com.google.api.client.googleapis.json.GoogleJsonResponseException: 400 Bad Request

"code" : 400,

} ],

我尝试用以下值替换 startTime：
span1.setStartTime("2016-08-04T01:00:00Z");
这给了我：

我还尝试添加一个结束时间：
span1.setEndTime("2016-08-04T01:00:01Z");
这也给我同样的错误。
我几乎不知道需要做什么，因为我找不到一个可用的 Java 示例。
预先感谢您提供有效解决方案的任何指示。
终于想通了。这是一个工作示例，其中指出了必填字段和可选字段。

}
}
虽然有些值是可选的，例如 startTime 或 endTime，但将某些值放在那里是有意义的。
由于 this question 显示了预期值并查看了描述每个字段的 REST API 文档，我设法将其组合在一起，尤其是对于跟踪 ID 等神秘值：
