在Netbeans中，刚刚创建了一个名为“Teste”的web应用程序，然后从数据库中创建了RESTfulWebServices，我在数据库中选择了上面创建的表。创建了两个包，第一个（实体）是与表vars相关的类，第二个（服务）是与提供的服务相关的

因此，我们的消费服务url是http://localhost:8080/Teste/resources/entity.grau

我尝试过不同的方法来改变发送的postfields，在postfields中注入数组，等等，仍然说同样的错误：

HTTP状态400-错误请求 客户端发送的请求语法不正确（请求错误）

当用户使用findAll（）方法时，这是通过.php开发的响应xml

如果有人能帮助我，我将不胜感激，因为我已经浪费了很多时间尝试这一点，但仍然不知道如何做。

如果直接在浏览器中运行webserive url，会得到什么？xml丢失了吗？如果我运行http://localhost:8080/Teste/resources/entity.grau，则响应与运行提供上述xml的.php相同。不需要，因为如果您检查元素，您可以在那里看到它。->尝试将内容长度添加到curl“content length:”的头选项中。strlen（$xml）@GBD不起作用，给出了Grizzly/1.9.46错误的请求
