在 iPhone 应用程序中使用 PayPal API
您好，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。我怎样才能得到它？ 如果可能的话，请举一些 iphone 中 paypalAPI 集成的例子。
我也想使用结账功能。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。
Hello I want to use Paypal in my iphone application, I have find the soapRequest to integrating the paypal API. My code is
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");
}
But here I am not getting the value of paypalUrlNVP. How can i get it??
And if possible then please give some example of paypalAPI integration in iphone.
I also want to use checkout functionality.I am new in this field so I have no idea about it. So, kindly give me whole sample code.
Thanks in advance.

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，但您实际上并不使用该字符串，而是调用 NVP（名称值对）API。
您需要决定实际要使用哪个。
NVP API 需要使用的 URL 是：
如此处所述：

You appear to be mixing up two different ways of calling the PayPal API. You have a SOAP XML string, which you don't actually use and also then call the NVP (name value pair) API.
You need to decide which you are actually going to use.
The URLs you need to use for the NVP API are:
As described here:

此外，我认为您应该对传入的名称和值参数进行 URL 编码。
Additionally, I think you should URL-encode the name and value parameters that you're passing in.
