iphone - 在 iPhone 应用程序中使用 PayPal API

Question

你好，我想在我的 iphone 应用程序中使用 Paypal，我找到了 soapRequest 来集成 paypal API。我的代码是

NSString *soapMessage =  [NSString stringWithFormat:
@"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" 
"<SOAP-ENV:Envelope xmlns:xsi= \"http://www.w3.org/2001/XMLSchema-instance\" xmlns:SOAP-ENC=\"http://schemas.xmlsoap.org/soap/encoding/\" xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" SOAP-ENV:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\">\n"
"<SOAP-ENV:Header>\n" 
"<RequesterCredentials xmlns=\"urn:ebay:api:PayPalAPI\">\n" 
"<Credentials xmlns=\"urn:ebay:apis:eBLBaseComponents\">\n" 
"<Username>api_username</Username>\n" 
"<Password>api_password</Password>\n" 
"<Signature/>\n"     
"<Subject/>\n" 
"</Credentials>\n" 
"</RequesterCredentials>\n" 
"</SOAP-ENV:Header>\n" 
"<SOAP-ENV:Body>\n" 
"<specific_api_name_Req xmlns=\"urn:ebay:api:PayPalAPI\">\n" 
"<specific_api_name_Request>\n" 
"<Version xmlns=urn:ebay:apis:eBLBaseComponents”>service_version</Version>\n" 
"<required_or_optional_fields xsi:type=”some_type_here”>\n"                 
"</required_or_optional_fields>\n" 
"</specific_api_name_Request>\n" 
"</specific_api_name_Req>\n" 
"</SOAP-ENV:Body>\n" 
                          "</SOAP-ENV:Envelope>\n"];

NSLog(@"Soap message===%@",soapMessage);


NSString *parameterString = [NSString stringWithFormat:@"USER=%@&PWD=%@&SIGNATURE=%@&VERSION=57.0&METHOD=SetMobileCheckout&AMT=%.2f&CURRENCYCODE=USD&DESC=%@&RETURNURL=%@", userName, password, signature, donationAmount, @"Some Charge", returnCallURL];

NSLog(parameterString);

NSURL *url = [NSURL URLWithString:paypalUrlNVP];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [parameterString length]];

[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [parameterString dataUsingEncoding:NSUTF8StringEncoding]];


NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

if( theConnection ){
    webData = [[NSMutableData data] retain];
//  [self displayConnectingView];

}else{
    NSLog(@"theConnection is NULL");
}

但在这里我没有得到 paypalUrlNVP 的值。我怎么才能得到它？？如果可能，请给出一些在 iphone 中集成 paypalAPI 的示例。

我也想使用结帐功能。我是这个领域的新手，所以我对此一无所知。所以，请给我完整的示例代码。提前致谢。

您似乎混淆了调用 PayPal API 的两种不同方式。您有一个 SOAP XML 字符串，您实际上并没有使用它，然后还调用了 NVP(名称值对)API。

您需要决定您实际要使用哪个。

您需要用于 NVP API 的 URL 是:

API Servers for API Signature Security

If you use an API signature, post the request to one ofthese servers:

Sandbox: https://api-3t.sandbox.paypal.com/nvp

Live: https://api-3t.paypal.com/nvp API Servers for API Certificate Security

If you use an API certificate, post the request to oneof these servers:

Sandbox: https://api.sandbox.paypal.com/nvp

Live: https://api.paypal.com/nvp

如这里所述:
