如何将NSArray发送到Web服务

问题描述

我没有成功将NSArray发送到Web服务。
$
不调用服务方法。但其他服务方法调用工作。

Web服务方法是：

I have no success to send NSArray to web service.
Service method is not called. But other service methods call works.
Web service method is:

[WebMethod]
        public int Method(IList items){...

我的数组中充满了对象项目：

My array is full of objects Items:

@interface Item : NSObject
{
    double prop1;
    double prop2;
    double prop3;
}
@property double prop1;
@property double prop2;
@property double prop3;

从目标c我尝试发送这样的数据：

From objective c I try to send data like this:

NSString *soapMsg =
    [NSString stringWithFormat:
     @"<?xml version=\"1.0\" encoding=\"utf-8\"?>"
     "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"
     "<soap:Body>"
     "<Method xmlns=\"http://www.mysite.com/\">"
     "<items>"
     "%@"
     "</items>"
     "</Method>"
     "</soap:Body>"
     "</soap:Envelope>", myArray
     ];

    NSURL *url = [NSURL URLWithString: @"http://...."];

    NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMsg length]];

    [req addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [req addValue:@"http://www.mysite.com/Method" forHTTPHeaderField:@"SOAPAction"];
    [req addValue:msgLength forHTTPHeaderField:@"Content-Length"];
    [req setHTTPMethod:@"POST"];
    [req setHTTPBody: [soapMsg dataUsingEncoding:NSUTF8StringEncoding]];

    conn = [[NSURLConnection alloc] initWithRequest:req delegate:self];

    if (conn)
    {
        webData = [NSMutableData data];
    }

更新


当我像这样制作数组时：

UPDATE

When I make array like this:

NSArray  * myArrDate = [NSArray arrayWithObjects:@"foo",@"bar",@"baz",nil];

并且赚取：

NSData *jsonData = [NSJSONSerialization dataWithJSONObject:myArrDate
                                                       options:0
                                                         error:nil];

它有效。
但我有一个对象 User 的数组，其中包含以下属性： UserId，FirstName，LastName，Email，Username，DisplayName，Country，City 等等。
当我尝试使用用户数组的代码崩溃时，该行代码崩溃。

It works.But I have an array with objects User which has properties: UserId, FirstName, LastName, Email, Username, DisplayName, Country, City etc.When I try above code with array of Users application crash on that line.

推荐答案

您可以将 NSArray 发送到 webservice

NSData *jsonData2 = [NSJSONSerialization dataWithJSONObject:yourArray options:NSJSONWritingPrettyPrinted error:nil];
         NSString *jsonString = [[NSString alloc] initWithData:jsonData2 encoding:NSUTF8StringEncoding];
         NSLog(@"FemaleFriendList:\n%@", jsonString);
