rest - 使用 REST API 创建 Sonatype Nexus 存储库导致 HTTP/1.1 400 错误请求

Question

在尝试使用 REST API 创建新的 Sonatype Nexus 托管存储库时，我收到“HTTP/1.1 400 错误请求”。我正在使用本地运行的 Sonatype Nexus™ 2.10.0-02。

根据 REST API 文档，可在以下位置获取

http://localhost:8081/nexus/nexus-restlet1x-plugin/default/docs/path__repositories.html

要创建新存储库，POST 请求必须如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<repository>
    <data>
       <format>...</format>
       <providerRole>...</providerRole>
       <exposed>...</exposed>
       <id>...</id>
       <name>...</name>
       <contentResourceURI>...</contentResourceURI>
       <repoType>...</repoType>
       <provider>...</provider>
    </data>
</repository>

所以，我的 XML 有效负载如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<repository>
    <data>
        <format>maven2</format>
        <providerRole>org.sonatype.nexus.proxy.repository.Repository</providerRole>
        <exposed>true</exposed>
        <id>my-releases</id>
        <name>MyReleases</name>
        <contentResourceURI>http://localhost:8081/nexus/content/repositories/my-releases</contentResourceURI>
        <repoType>hosted</repoType>
        <provider>maven2</provider>
    </data>
</repository>

到目前为止(我希望)没问题。

我使用 cURL 来发布此 XML 内容:

curl -i -H "Accept: application/xml" -H "Content-Type: application/xml" -f -X POST -v -d "@$(pwd)/insert_oss_repository.xml" -u admin:admin123 http://localhost:8081/service/local/repositories

该命令的完整日志是这样的:

首先，我会阅读您关于我的 POST 请求的 XML 负载的评论。其次，如果他们花时间创建某种文档，为什么他们不提供一个有效的示例呢？第三，如果他们提供了此 REST API，为什么他们不以人类可读的答案进行响应？

Answer 1

看起来文档中可能存在错误，您还需要提供“repoPolicy”元素。这是一个示例有效负载:

<repository>
  <data>
    <id>my-releases-xml</id>
    <name>MyReleasesXml</name>
    <exposed>true</exposed>
    <repoType>hosted</repoType>
    <repoPolicy>RELEASE</repoPolicy>
    <providerRole>org.sonatype.nexus.proxy.repository.Repository</providerRole>
    <provider>maven2</provider>
    <format>maven2</format>
  </data>
</repository>

一般来说，使用 Nexus 和 REST 的最佳方法是使用 JSON 有效负载，这些有效负载很容易发现，因为 UI 通过 REST 层调用并发送 JSON。请参阅此处了解更多信息:
