Question

我正在尝试运行Bing搜索API。我使用odata4j并尝试了这里提供的代码： How to use Bing search api in Java

ODataConsumer c = ODataConsumers
    .newBuilder("https://api.datamarket.azure.com/Bing/Search")
    .setClientBehaviors(OClientBehaviors.basicAuth("accountKey", "{your account key here}"))
    .build();

OQueryRequest<OEntity> oRequest = c.getEntities("Web")
    .custom("Query", "stackoverflow bing api");

Enumerable<OEntity> entities = oRequest.execute();

我在bing服务中注册后，获得了密钥并将其放在上面代码中的双引号内。我收到以下错误：

Exception in thread "main" java.lang.RuntimeException: Expected status OK, found Bad Request. Server response:

我无法弄清楚问题。

Answer 1

您需要的只是设置您的查询，例如％27stackoverflow bing api％27

这是我的源代码：

ODataConsumer consumer = ODataConsumers
            .newBuilder("https://api.datamarket.azure.com/Bing/Search/v1/")
            .setClientBehaviors(
                    OClientBehaviors.basicAuth("accountKey",
                            "{My Account ID}"))
            .build();

    System.out.println(consumer.getServiceRootUri() + consumer.toString());

    OQueryRequest<OEntity> oQueryRequest = consumer.getEntities("Web")
            .custom("Query", "%27stackoverflow%27");

    System.out.println("oRequest : " + oQueryRequest);

    Enumerable<OEntity> entities = oQueryRequest.execute();
    System.out.println(entities.elementAt(0));

您可以通过使用oQueryrequest对象的.custom（＆＃34;参数类型＆＃34;，＆＃34;参数＆＃34;）继续添加名称 - 值对来进一步尝试使用不同过滤器的不同查询。你想搜索印度菜，但你只想要小方形图像。

    ODataConsumer consumer = ODataConsumers
            .newBuilder("https://api.datamarket.azure.com/Bing/Search/v1/")
            .setClientBehaviors(
                    OClientBehaviors.basicAuth("accountKey",
                            "YOUR ACCOUNT KEY"))
            .build();

    System.out.println(consumer.getServiceRootUri() + consumer.toString());

    OQueryRequest<OEntity> oQueryRequest = consumer.getEntities("Image")
            .custom("Query", "%27indian food%27");    
    oQueryRequest.custom("Adult", "%27Moderate%27");
    oQueryRequest.custom("ImageFilters", "%27Size:Small+Aspect:Square%27");
    System.out.println("oRequest : " + oQueryRequest);

    Enumerable<OEntity> entities = oQueryRequest.execute();

    int count = 0;
    Iterator<OEntity> iter = entities.iterator();
    System.out.println(iter.next());
