Objective-C调用SharePoint 2010上的Get List Web服务不返回任何数据

开始尝试使用Web服务调用SharePoint(2010),并使GetWebCollectionGetListCollection等调用正常工作并返回预期数据。运行GetListCollection会按预期返回所有SP列表。

<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>
<GetListCollection xmlns="http://schemas.microsoft.com/sharepoint/soap/" />
</soap:Body>
</soap:Envelope>

从返回的SP列表中,我提取日历列表的内部名称{A2CEBD3C-D07A-44A3-BE34-975AFE57F56C}

<_sList>
    <InternalName>{A2CEBD3C-D07A-44A3-BE34-975AFE57F56C}</InternalName>
    <Title>Calendar</Title>
    …..

当我尝试使用该ID值进行GetList调用时出现问题:

NSString *soapFormat = [NSString stringWithFormat:@"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
                        "<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/\">\n"
                        "<soap:Body>\n"
                        "<GetList xmlns=\"http://schemas.microsoft.com/sharepoint/soap/\" />\n"
                        "<listName>{A2CEBD3C-D07A-44A3-BE34-975AFE57F56C}</listName>\n"
                        "</GetList>\n"
                        "</soap:Body></soap:Envelope>\n"];


    NSLog(@"Request is : %@",soapFormat);

    NSURL *locationOfWebService = [NSURL URLWithString:@"http://192.168.0.114/_vti_bin/lists.asmx"];

    NSLog(@"Web url = %@",locationOfWebService);

    NSMutableURLRequest *theRequest = [[NSMutableURLRequest alloc]initWithURL:locationOfWebService];

    NSString *msgLength = [NSString stringWithFormat:@"%d",[soapFormat length]];


    [theRequest addValue:@"text/xml" forHTTPHeaderField:@"Content-Type"];
    [theRequest addValue:@"http://schemas.microsoft.com/sharepoint/soap/GetList"
                            forHTTPHeaderField:@"SOAPAction"];
    [theRequest addValue:msgLength forHTTPHeaderField:@"Content-Length"];
    [theRequest setHTTPMethod:@"POST"];

当我在iPad 5.1模拟器中运行时,GetList调用进行身份验证并连接,但返回0字节。

在另一个工作站上使用Fiddler并使用U2U CAML Query Builder我可以看到U2U产品在启动时发出GetListCollectionGetAllSubWebCollections(现在知道所有站点和列表),当我加倍时点击他们发送此SOAP请求的日历列表:

POST http://g2010/_vti_bin/lists.asmx HTTP/1.1
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; MS Web Services Client Protocol 2.0.50727.5466)
Content-Type: text/xml; charset=utf-8
SOAPAction: "http://schemas.microsoft.com/sharepoint/soap/GetList"
Host: g2010
Content-Length: 378
Expect: 100-continue
Connection: Keep-Alive

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<GetList xmlns="http://schemas.microsoft.com/sharepoint/soap/">
<listName>{A2CEBD3C-D07A-44A3-BE34-975AFE57F56C}</listName>
</GetList>
</soap:Body>
</soap:Envelope>

这将返回List字段,并允许我构建CAML查询,然后返回日历列表中的2个项目。我没看到为什么我对GetList的调用没有返回任何数据,并希望有人能发现我明显的错误: - )

谢谢!

这种解释可能有点矫枉过正,而不是不清楚。您的GetList代码会在代码块中提前结束。

<GetList xmlns="http://schemas.microsoft.com/sharepoint/soap/" />
    <listName>{A2CEBD3C-D07A-44A3-BE34-975AFE57F56C}</listName>
</GetList>

第一个GetList标记的最后一个/确保GetList立即关闭。写<GetList />与写<GetList></GetList>相同。所以你的代码块被视为:

<GetList xmlns="http://schemas.microsoft.com/sharepoint/soap/" >
</GetList>
<listName>{A2CEBD3C-D07A-44A3-BE34-975AFE57F56C}</listName>
</GetList>

其中前两行是一个没有listName的GetList,第三行是listName但是它周围没有GetList,第四行是“GetList的结束”标记什么都没有。

删除第一个GetList标记的最后一个/哪个应该可以使一切正常: - )
