PayPal文档中的cURL示例:
curl https://api.sandbox.paypal.com/v1/payments/payment \
-v \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer accessToken' \
-d '{
"intent":"sale",
"redirect_urls":{
"return_url":"http://return_URL_here",
"cancel_url":"http://cancel_URL_here"
},
"payer":{
"payment_method":"paypal"
},
"transactions":[
{
"amount":{
"total":"7.47",
"currency":"USD"
},
"description":"This is the payment transaction description."
}
]
}'
以下是我通过上述NSLog声明从PayPal得到的回复:
采购响应:

有人请告诉我为什么付款没有通过。我没有收到错误(或者它不会打印响应),我知道令牌是好的,因为我每次使用应用程序时都必须登录到PayPal,我无法找到它。谢谢
C您应该将JSON数据打印到console,而不是打印NSURlResponse描述,以便更好地了解情况。将代码修改为如下所示:
NSURLSessionUploadTask *task = [session uploadTaskWithRequest:request fromData:postData completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if (!error) {
NSError* jsonError;
NSDictionary* json = [NSJSONSerialization JSONObjectWithData:data
options:kNilOptions
error:&jsonError];
NSLog(@"\nPurchase Response:\n\n%@", json); //You will have to edit this to use the actual error object returned from the curl request.
} else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Authorization Failed" message:@"Your payment did not go through." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
[alert show];
}
}];
一旦你做到了这一点,你应该对出了什么问题有一个更好的了解
更新:
我现在看到了更多正在发生的事情。您的请求格式确实不正确:您的post和post数据值不正确;您正在发送一个字符串值(就像通过url发送一样),而不是json(以下几行)
将这两行替换为:
NSError *jsonError;
NSData *postData = [NSJSONSerialization dataWithJSONObject:dataDict options:0 error:&error];
谢谢@jrobe-在我发布问题之前,本来应该这样做的。正如我认为JSON请求有问题一样:购买响应:{“debug_id”=fbcc3a0134a8;“information_link”=“message=”请求JSON格式不正确。“name=”格式不正确的请求“}我的朋友,你是圣人。再次感谢@这不是问题,我的荣幸!
NSError *jsonError;
NSData *postData = [NSJSONSerialization dataWithJSONObject:dataDict options:0 error:&error];
