带有改造的Paypal REST Api

如何解决带有改造的Paypal REST Api

我正在尝试对Paypal REST api进行改造，但出现以下错误

{"name":"INVALID_REQUEST","message":"Request is not well-formed,syntactically incorrect,or violates schema.","debug_id":"2689a7ff7bf28","details":[{"field":"/purchase_units","value":"","location":"body","issue":"MISSING_REQUIRED_PARAMETER","description":"A required field / parameter is missing."},{"field":"/intent","description":"A required field / parameter is missing."}],"links":[{"href":"https://developer.paypal.com/docs/api/orders/v2/#error-MISSING_REQUIRED_PARAMETER","rel":"information_link","encType":"application/json"}]

这是请求正文

Request{method=POST,url=https://api.sandbox.paypal.com/v2/checkout/orders/?%2Fintent=CAPTURE&%2Fpurchase_units=%5B%7B%22currency_code%22%3A%22USD%22%2C%22value%22%3A%22100%22%7D%5D,tags={class retrofit2.Invocation=c.shobaky.tofahaway.orderRequest.Order() [application/json,Bearer A21AAJ-S4HTuRR7ip1zAflRxUBsIVeEkxAAVWM7ZEB7uvn8g-0GBk6Swa3gwWMIiQYBtsXUssvzKWHv6IHDHYIQjREv6ToYow,CAPTURE,[{"currency_code":"USD","value":"100"}]]}}

这是代码

 Gson gson = new GsonBuilder()
            .setLenient()
            .create();
    Retrofit retrofit = new Retrofit.Builder().baseUrl("https://api.sandbox.paypal.com/v2/checkout/")
            .addConverterFactory(GsonConverterFactory.create(gson)).build();
    orderRequest Order = retrofit.create(orderRequest.class);


    JSONArray Purchase = new JSONArray();
    JSONObject Amount = new JSONObject();
    try {
        Amount.put("currency_code","USD");
        Amount.put("value","100");
    } catch (JSONException e) {
        e.printStackTrace();
    }
    Purchase.put(Amount);


    Call<String> call = Order.Order("application/json","Bearer A21AAJ-S4HTuRR7ip1zAflRxUBsIVeEkxAAVWM7ZEB7uvn8g-0GBk6Swa3gwWMIiQYBtsXUssvzKWHv6IHDHYIQjREv6ToYow","CAPTURE",Purchase);
    call.enqueue(this);

}

@Override
public void onResponse(Call<String> call,Response<String> response) {
    try {
        Log.d("RESPONEPYPAL",call.request().toString()+response.errorBody().string());
    } catch (IOException e) {
        e.printStackTrace();
    }
}

@Override
public void onFailure(Call<String> call,Throwable t) {

}

我通过传递客户端ID和秘密ID来使用curl获取访问令牌，因此我几乎可以确定这与授权无关，它似乎与“意图”和“购买单位”有关

更新 我在上一个请求之前使用了此请求，但也没有成功

{method=POST,url=https://api.sandbox.paypal.com/v2/checkout/orders/,Bearer A21AAJQvfCFvMKkiWA9anZaEU_hBJ0Pb_TPOQtjqtCjFc39nc_rX6Y5RsCKoYbseMjgiCeGPMhyD5Omqw2tUlgh2EZT-9kiXQ,[{"amount":{"currency_code":"USD","value":"100"}}]]}}

解决方法

您的“请求正文”不仅显示带有查询字符串参数的URL，这是错误的，而且还向PayPal发送了一个空的POST正文，这是格式正确的JSON，其中带有purchase_units数组必须是。

cURL在Windows提示符下无法正常工作，因此我使用了Power Shell并且运行良好！
