Java的Google + Domains API快速入门无法正常工作

Question

I am trying to use the domains API offered in Google +, I am trying to make work to Quick start for java using domain-wide delegation I have followed the steps, also I have asked my domain admin to grant access to the project I created in console, resuming I can compile the java file, but when I run, I get a 404 error, here is the code:

I am lost, please if somebody could help me I would be grateful.

Answer 1

It appears that the line that contains PlusDomains.builder now requires that the setApplicationName be called:

PlusDomains service = new PlusDomains.Builder(httpTransport, jsonFactory, credential)
  .setApplicationName('MyDomainsDemo')
  .build();

Answer 2

I tested the Java sample today and it works. The instructions need a few minor updates related to labels changing in the API console, but if you configure the application correctly, you will be able to get started.

The 404 error is most likely caused by a misconfigured client and is not an issue in the sample. The following screenshot should be helpful in getting the correct credentials. When you create the service account, you will get a new region highlighted below:

Make sure that the Client ID under Service Account is the same client ID added when you performed Domain-Wide delegation from the Admin console. The following screenshot shows where the client ID (the first field in the previous screenshot) goes:

Finally, make sure that the email address configured in src/com/google/plus/samples/quickstart/domains/DomainDelegation.java matches the email from your service account.

If you are using the classic API console, you will need to add a service account to your project, Do this from API Access -> Create another client ID... -> Service account. The values will then come from the added section:

this works!

Answer 4

I ran into this problem recently. For me the solution was to update the library (the sample comes with a bunch of out-dated JARs in the lib/ folder).

My maven dependencies:

<dependencies>
    <dependency>
        <groupId>com.google.api-client</groupId>
        <artifactId>google-api-client</artifactId>
        <version>1.23.0</version>
    </dependency>

    <dependency>
        <groupId>com.google.apis</groupId>
        <artifactId>google-api-services-plusDomains</artifactId>
        <version>v1-rev449-1.23.0</version>
    </dependency>

    <dependency>
        <groupId>com.google.http-client</groupId>
        <artifactId>google-http-client-jackson</artifactId>
        <version>1.23.0</version>
    </dependency>
</dependencies>
