我不确定为什么这个PayPal Pay操作会给我这个错误,即使我似乎已经涵盖了所有必填字段:
错误代码:81002严重性:错误消息:未指定方法(不支持指定的方法)“
string postData = JsonConvert.SerializeObject(request);
postData的值:
"actionType=PAY
¤cyCode=USD
&cancelUrl=https%3a%2f%2fexample.com%2fcancel
&returnUrl=https%3a%2f%2fexample.com%2freturn
&requestenvelope.errorLanguage=en_US
&receiverList.receiver(0).email=recipientemail%40gmail.com
&receiverList.receiver(0).amount=0.05
&VERSION=94.0
&USER=bizemail-facilitator_api1.gmail.com
&PWD=xxxxx
&SIGNATURE=xxxxxxxxx"
以下是我发布帖子的方式:
SendRequest("https://api-3t.sandbox.paypal.com/nvp", postData);
public string SendRequest(string url, string postData)
{
var uri = new Uri(url);
var request = WebRequest.Create(uri);
var encoding = new UTF8Encoding();
var requestData = encoding.GetBytes(postData);
request.ContentType = "application/x-www-form-urlencoded";
request.Method = "POST";
request.Timeout = (300*1000); //TODO: Move timeout to config
request.ContentLength = requestData.Length;
using (var stream = request.GetRequestStream()) {
stream.Write(requestData, 0, requestData.Length);
}
var response = request.GetResponse();
string result;
using (var reader = new StreamReader(response.GetResponseStream(), Encoding.ASCII)) {
result = reader.ReadToEnd();
}
return result;
}

方法PAY
在NVP api上不存在。找到该API支持的完整方法列表here。
然而,PAY
方法在Adaptive Payments
API中定义。根据您的需要,您有两种选择:
https://svcs.paypal.com/AdaptivePayments/PAY
并修改您的值DoDirectPayment
,但我不确定它是否符合您的要求。答案 1 :(得分:1)
我假设postData的值是之前你将它序列化为JSON字符串,而不是像你说的那样,因为它显然是不一个JSON字符串。< / p>
如果是,那么它已经是x-www-form-urlencoded
,您根本不需要将其序列化为JSON字符串。
或者如果你这样做了,那就改变一下:request.ContentType = "application/json";
