我正在使用JSON库从Objective C创建一个JSON POST请求,如下所示:
NSMutableURLRequest *request; request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@/%@/", host, action]]]; [request setHTTPMethod:@"POST"]; [request setValue:@"application/json-rpc" forHTTPHeaderField:@"Content-Type"]; NSMutableDictionary *requestDictionary = [[NSMutableDictionary alloc] init]; [requestDictionary setObject:[NSString stringWithString:@"12"] forKey:@"foo"]; [requestDictionary setObject:[NSString stringWithString@"*"] forKey:@"bar"]; NSString *theBodyString = requestDictionary.JSONRepresentation; NSData *theBodyData = [theBodyString dataUsingEncoding:NSUTF8StringEncoding]; [request setHTTPBody:theBodyData]; [[NSURLConnection alloc] initWithRequest:request delegate:self];
当我在Django视图中读取此请求时,调试器显示它占用了整个JSON字符串并使其成为POST QueryDict的第一个键:
POST QueryDict: QueryDict: {u'{"foo":"12","bar":"*"}': [u'']}> Error Could not resolve variable
我可以读取第一个键,然后使用JSON作为黑客重新解析.但为什么JSON字符串没有正确发送?
在整个互联网上,甚至包括在Stack Overflow中,人们声称检查请求是否是AJAX的好方法是执行以下操作:
if (strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest' ) {...}

但是,我没有$_SERVER['HTTP_X_REQUESTED_WITH']在官方PHP文档中看到
当我尝试执行以下操作时:
echo $_SERVER['HTTP_X_REQUESTED_WITH'];

什么都没输出.
难道我做错了什么?因为我真的希望能够使用$_SERVER['HTTP_X_REQUESTED_WITH']它是否可用.
我看到了这个问题
关于如何手动注入带注释的私有字段(方式是添加setter或通过构造函数)
但是,重点是应用程序服务器(如glassfish,axis2,jboss,...)如何能够注入最终的私有字段(不向用户类添加setter或构造函数)?

public SomeClass {
@Inject
private SomeResource resource;
}

他们是否使用允许访问私有字段的自定义JVM(不是标准的JVM)?

在迭代内部,有一种简单的方法,无需保持计数器,看看循环当前在哪个迭代?

属性的功能是确定函数是否可以运行...
所以我需要的是以下内容:
这是我到目前为止,但它只实现了第1,3点.
[AttributeUsage(AttributeTargets.Method, AllowMultiple = false)]
public class ExecuteMethodAttribute : Attribute
{
private Func<object, bool> canExecute;
public Func<object, bool> CanExecute

{
this.canExecute = canExecute;
}

这是最初的WCF App.config,当我运行该服务时,WCF测试客户端可以正常使用它:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
<compilation debug="true" />

这完美无缺,完全没有问题.
我认为将其从HTTP更改为TCP将是微不足道的:将绑定更改为其TCP等效项并删除httpGetEnabled serviceMetadata元素:
