Question

我正在尝试从iPhone应用程序访问WCF服务，但我收到以下错误：

AFHTTPRequestOperation错误：错误域= AFNetworkingErrorDomain代码= -1011“请求失败：内部服务器错误（500）”UserInfo = 0x8c75b90 {NSErrorFailingURLKey = http://xxx.xxx.xx.xxx/accessserviceshost/servicecontroller/holdingslistservice.svc，AFNetworkingOperationFailingURLResponseErrorKey = {URL：http://xxx.xxx.xx.xxx/accessserviceshost/servicecontroller/holdingslistservice.svc} {status代码：500，headers { “Cache-Control”=私有; “内容长度”= 736; “Content-Type”=“text / xml; charset = utf-8”; 日期=“星期二，2014年3月25日10:14:58 GMT”; Server =“Microsoft-IIS / 6.0”; “X-AspNet-Version”=“4.0.30319”; “X-Powered-By”=“ASP.NET”; ，NSLocalizedDescription =请求失败：内部服务器错误（500）}

以下是我访问该服务的代码：

NSURL *baseURL = [NSURL URLWithString:@"http://xxx.xxx.xx.xxx/accessserviceshost/servicecontroller/holdingslistservice.svc"];
NSString *soapBody = [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><HoldingsListInput xmlns=\"http://tempuri.org/\">"
                      "<Account_Id>1000</Account_Id>"
                      "<Allow_Global_Processing_Fl></Allow_Global_Processing_Fl>"
                      "<Asset_Class_Cd></Asset_Class_Cd>"
                      "<Cash_Balances_Cd>Y</Cash_Balances_Cd>"
                      "<Display_Cd>TA</Display_Cd>"
                      "<Industry_Class_Cd>30</Industry_Class_Cd>"
                      "<Invested_Income_Portfolio_Cd>Y</Invested_Income_Portfolio_Cd>"
                      "<Local_Fl>Y</Local_Fl>"
                      "<Positions_As_Of_Cd>TD</Positions_As_Of_Cd>"
                      "<Principal_Portfolio_Cd>Y</Principal_Portfolio_Cd>"
                      "<Security_Tp>48</Security_Tp>"
                      "<Show_Position_Instructions_Fl>Y</Show_Position_Instructions_Fl>"
                      "<Sort_Cd>MA</Sort_Cd>"
                      "<Unique_Assets_Only_Cd>Y</Unique_Assets_Only_Cd>"
                      "<Very_Liquid_Asset_Classes_Cd>X</Very_Liquid_Asset_Classes_Cd>"
    "</HoldingsListInput></soap:Body></soap:Envelope>"];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:baseURL];

[request setHTTPMethod:@"POST"];
[request setHTTPBody:[soapBody dataUsingEncoding:NSUTF8StringEncoding]];
[request addValue:@"http://tempuri.org/RetrieveHoldingList" forHTTPHeaderField:@"SOAPAction"];
[request addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

    NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSLog(@"%@", string);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"%s: AFHTTPRequestOperation error: %@", __FUNCTION__, error);
}];

[operation start];

我已经在asp.net页面上检查了相同输入的服务，但它在那里工作但我无法在iPhone应用程序上运行它。

- 试试这种方式。 IT可能有所帮助。以这种方式编辑你的Soap Request字符串，可能就是问题所在。

NSString *soapRequest =[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"
    "<Login xmlns=\"http://tempuri.org/\">\n"
    "<UID>%@</UID>\n"
    "<Password>%@</Password>\n"
    "</Login>\n"
    "</soap:Body>\n"
    "</soap:Envelope>\n",@"Test",@"Test"];


    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
        [request addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[request addValue:@"http://tempuri.org/RetrieveHoldingList" forHTTPHeaderField:@"SOAPAction"];
        NSString *msgLength = [NSString stringWithFormat:@"%lu",(unsigned long)[soapRequest length]];
        [request addValue:msgLength forHTTPHeaderField:@"Content-Length"];
        [request setHTTPMethod:@"POST"];
        [request setHTTPBody:[soapRequest dataUsingEncoding:NSUTF8StringEncoding]];

SOAPUI来救我。 JASON有一个缺陷。我使用SOAPUI构建请求和其他需要的参数，它对我来说很好。

无法访问iPhone上基于WCF构建的SOAP服务
