尝试使用android / java中的odata4j向odata服务器发帖

标签: java android odata odata4j

我正在尝试使用odata4j lib向客户端的服务器发送OData帖子。我这样做是通过创建自定义CursorWrapper来获取每列的类型。似乎无论我做什么,我都会收到“406 Not Acceptable”错误。

odata4j javadocs并不是最好的,并且在odata4j网站以及一般的谷歌搜索中都存在严重缺乏的例子。我甚至不确定如何记录发布到OData服务器的内容(我确信这会使错误清除)。似乎没有明显的功能将xml帖子转换为字符串。

所以,我的问题是一个2部分的问题: 1.如何从odata4j lib中记录事务? 2.使用odata4j制作OData帖子的逻辑中有什么错误?

我在下面附上了一个代码段。任何帮助将不胜感激。

    // Create the ODataConsumer with the appropriate credentials
    OClientBehavior basicAuth = new BasicAuthenticationBehavior(Config.dbfile + 
                                    "\\" + Config.username, Config.password);       
    ODataConsumer consumer = ODataConsumer.create(url, basicAuth);          

    // Make sure there are results in the cursor
    if ( cursorWrapper.moveToFirst() ){

        // create the new product
        OCreateRequest<OEntity> newMaterial = 
            consumer.createEntity( "ESvcOrderTrans" );         
        // Iterate through each cursor's row
        while (cursorWrapper.isAfterLast() == false) {      
            // Iterate through each cursor's columns
            for ( int i=1; i < cursorWrapper.getColumnCount(); i++ ){   
                // Determine type of key
                    switch ( cursorWrapper.getType(i) ){
                        case CustomCursorWrapper.FIELD_TYPE_INTEGER :
                            if (cursorWrapper.isNull(i)){
                                createRequest.properties(OProperties.null_(
                                        cursorWrapper.getColumnName(i), 
                                        "Edm.Int32"));
                            } else {
                                createRequest.properties(   OProperties.int32( 
                                        cursorWrapper.getColumnName(i), 
                                        cursorWrapper.getInt(i)));
                            }
                            break;  
                        case CustomCursorWrapper.FIELD_TYPE_STRING :
                            if (cursorWrapper.isNull(i)){
                                createRequest.properties(OProperties.null_(
                                        cursorWrapper.getColumnName(i),

                            } else {
                                createRequest.properties(OProperties.string(
                                        cursorWrapper.getColumnName(i), 
                                        cursorWrapper.getString(i)));
                            }
                            break;
                        case CustomCursorWrapper.FIELD_TYPE_FLOAT :
                            if (cursorWrapper.isNull(i)){
                                createRequest.properties(OProperties.null_(

                            }
                            break;

                                createRequest.properties(OProperties.null_(
                                        cursorWrapper.getColumnName(i), 
                                        "Edm.Binary"));
                            } else {
