使用REST API創建Sonatype Nexus存儲庫導致HTTP/1.1 400錯誤請求

Question

在嘗試使用REST API創建新的Sonatype Nexus託管存儲庫時，出現「HTTP/1.1 400錯誤請求」。我正在使用Sonatype Nexus™2.10.0-02，在本地運行。

按照REST API文檔，可在

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

創建一個新的存儲庫中的POST請求必須是這樣的：

<?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負載看起來是這樣的：

<?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> 

和到這裏（我希望）是可以的。

我使用捲曲發佈此XML內容：

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 

完整的日誌這個命令是這樣的：

* Trying 127.0.0.1... 
* Connected to localhost (127.0.0.1) port 8081 (#0)

    </error> 
    </errors> 
* Connection #0 to host localhost left intact 
</nexus-error> 

首先，我會讀關於XML負載的評論我的POST請求。其次，如果他們花時間創建一種文檔，爲什麼他們不提供一個工作示例？第三，如果他們使這個REST API可用，爲什麼他們不回答人類可讀的答案？

它看起來像文檔中可能存在一個錯誤，您還需要提供「repoPolicy」元素。下面是一個例子有效載荷：

<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> 

一般來說，最好的辦法適用於Nexus使用和REST是使用JSON有效載荷，這些都是很容易被發現，因爲UI呼籲通過REST層和發送JSON。在這裏看到更多的信息：
