ios - NSString被截断

在我的应用中，我正在使用对文档进行签名的Web服务。我必须在SOAP调用中以base64format发送文档。问题是，当我尝试发送一个11mb的大文件时，base64（存储在NSString中）很大，并且SOAP消息被截断了。

因此，我可以适当地发送SOAP调用，并且收到服务器错误。

是否有可以存储大（非常大）字符串的类？

编辑：这是我使用的代码：

要将文档转换为base64：

NSData *signData = [[NSFileManager defaultManager] contentsAtPath:self.pathDocument];
NSString *base64file = [signData base64EncodedString];

要执行呼叫：

NSString *soapMsg = [NSString stringWithFormat:@"<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:tem=\"http://tempuri.org/\" xmlns:seal=\"http://schemas.datacontract.org/2004/07\">"
                   "<soapenv:Header/>"
                   "<soapenv:Body>"
                   "<tem:Sign>"
                   "<tem:type>Signature</tem:type>"
                   "<tem:biometricState>%@</tem:biometricState>"
                   "<tem:idCertificate>%d</tem:idCertificate>"
                   "<tem:signatureProfile>%@</tem:signatureProfile>"
                   "<tem:signatureType>Default</tem:signatureType>"
                   "<tem:hashAlgorithm>Default</tem:hashAlgorithm>"
                   "<tem:options>%@</tem:options>"
                   "<tem:signingDocument>%@</tem:signingDocument>"
                   "</tem:Sign>"
                   "</soapenv:Body>"
                   "</soapenv:Envelope>",
                   aSign,
                   [aCertificado idCert],
                   tipoFirma,
                   flagFirma,
                   aDocument
                   ];

NSString *stringURL = [NSString stringWithFormat:@"http://%@//Service/SignatureServiceBasic.svc", [settings servidor]];
    NSURL *sRequestURL = [NSURL URLWithString:stringURL];
    NSMutableURLRequest *myRequest = [NSMutableURLRequest requestWithURL:sRequestURL];
    NSString *sMessageLength = [NSString stringWithFormat:@"%d", [soapMsg length]];

    [myRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [myRequest addValue:@"http://tempuri.org/ISignatureServiceBasic/Sign" forHTTPHeaderField:@"SOAPAction"];
    [myRequest addValue: sMessageLength forHTTPHeaderField:@"Content-Length"];
    [myRequest setHTTPMethod:@"POST"];
    [myRequest addValue:@"Jakarta Commons-HttpClient/3.1" forHTTPHeaderField:@"User-Agent"];
    [myRequest setHTTPBody: [soapMsg dataUsingEncoding:NSUTF8StringEncoding]];

    NSString* username = [settings usuario];
    NSString* password = [settings pass];

    NSString *authStr = [NSString stringWithFormat:@"%@:%@", username, password];
    NSData *authData = [authStr dataUsingEncoding:NSASCIIStringEncoding];
    NSString *authValue = [NSString stringWithFormat:@"Basic %@", [authData base64EncodingWithLineLength:80]];
    [myRequest setValue:authValue forHTTPHeaderField:@"Authorization"];


    signConnection = [[NSURLConnection alloc] initWithRequest:myRequest delegate:self];

    if( signConnection ) {
        webResponseData = [NSMutableData data];
    }else {
        NSLog(@"Some error occurred in Connection");

    }

aDocument是base64中的文档。

提前致谢！

最佳答案

不，没有这样的课程..但是你可以尝试一件事
尝试以块而不是大文件的形式创建数据，然后使用流将该数据发送到服务器。
