发生httpsurlconnection 400错误请求错误

firebase swift ios android java

我需要将SWIFT代码转换为Java。 SWIFT代码有效。但是,Java代码不起作用。

httpsurlconnection失败。

responseCode:400(httpsurlConnection.getResponseCode())

消息2:错误请求(httpsurlConnection.getResponseMessage())

如何解决400个错误的请求错误。

以迅捷的速度

func sendnotification(token:string,message:string){

//FireBase CloudMessaging服务器密钥
var firebaseserverkey=“aaaaa 6qlps4:apa91be7szgaggp3qygojsrssrm1inhigf5fq1x3xx”

让url=url(字符串:“https://fcm.googleapis.com/fcm/send”)!
var请求=urlRequest(url:url)
request.setvalue(“application/json”,forhttpheaderfield:“内容类型”)

request.setvalue(“key=\(firebaseserverkey)”,forhttpheaderfield:“授权”)
request.httpmethod=“发布”

request.httpbody=“\”to\“:\”(token)\“,\”notification\“:\”body\“:\”(message)\“,\”badge\“:\”1\“”。数据(使用.utf8)

}
< /代码> 

我用Java编写(未工作)

private void sendnotification(字符串标记,字符串消息){
//FireBase CloudMessaging服务器密钥
var firebaseserverkey=“aaaaa 6qlps4:apa91be7szgaggp3qygojsrssrm1inhigf5fq1x3xx”

试试看{
url url=new url(“https://fcm.googleapis.com/fcm/send”);
httpsurlConnection conn=(httpsurlConnection)url.openConnection();
conn.setreadtimeout(10000);
连接设置连接超时(15000);
conn.setrequestmethod(“post”);
conn.setdoinput(真);
conn.setdooutput(真);
conn.setrequestproperty(“内容类型”,“应用程序/json”);
conn.setrequestproperty(“授权”,“key=”+firebaseserverkey);


string str=“\”to \“:”+token+“,\”notification\“:\”body\“:”+message+“,\”badge\“:\”1\“”;


byte[]输出bytes=str.getbytes(“utf-8”);
outputstream os=conn.getOutputstream();
os.write(输出字节);
关闭();

int responseCode=conn.getResponseCode();//responseCode:400

if(responseCode==httpsurlConnection.http_OK){
log.d(“成功”,string.valueof(responseCode));
}否则{
字符串代码=string.valueof(responseCode);
string message2=conn.getResponseMessage();//message2:请求错误
log.d(“失败”,string.valueof(responseCode));
log.d(“fail2”,conn.getResponseMessage());
}
}
< /代码> 

.

消息2:错误请求(httpsurlConnection.getResponseMessage())


如何解决400个错误的请求。

在斯威夫特(它工作)

func sendNotification(token: String, message: String) {

 //Firebase CloudMessaging serverkey
    var firebaseServerKey = "AAAAA6qLps4:APA91bE7szGAgp3qYGOJsrSsrM1InhIgf5Fq1xxxxxx"

    let url = URL(string: "https://fcm.googleapis.com/fcm/send")!
    var request = URLRequest(url: url)
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")

    request.setValue("key=\(firebaseServerKey)", forHTTPHeaderField: "Authorization")
    request.httpMethod = "POST"

    request.httpBody = "{\"to\":\"\(token)\",\"notification\":{\"body\":\"\(message)\",\"badge\":\"1\"}}".data(using: .utf8)

}


我用Java编写(不工作)

private void sendNotification(String token, String message) {
//Firebase CloudMessaging serverkey
    var firebaseServerKey = "AAAAA6qLps4:APA91bE7szGAgp3qYGOJsrSsrM1InhIgf5Fq1xxxxxx"

    try {
        URL url = new URL("https://fcm.googleapis.com/fcm/send");
        HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
        conn.setReadTimeout(10000);
        conn.setConnectTimeout(15000);
        conn.setRequestMethod("POST");
        conn.setDoInput(true);
        conn.setDoOutput(true);
        conn.setRequestProperty("Content-Type", "application/json");
        conn.setRequestProperty("Authorization", "key="+firebaseServerKey);


        String str = "{\"to\": " + token + ", \"notification\": { \"body\": " + message + ", \"badge\": \"1\"}}";


        byte[] outputInBytes = str.getBytes("UTF-8");
        OutputStream os = conn.getOutputStream();
        os.write(outputInBytes);
        os.close();

        int responseCode = conn.getResponseCode(); // responseCode: 400

        if (responseCode == HttpsURLConnection.HTTP_OK) {
            Log.d("Success", String.valueOf(responseCode));
        } else {
            String code = String.valueOf(responseCode);
            String message2 = conn.getResponseMessage(); // message2: Bad Request
            Log.d("Fail", String.valueOf(responseCode));
            Log.d("Fail2", conn.getResponseMessage());
        }
}

您的JSON请求主体不正确。它生产 {"to": zxc} 这是无效的JSON。把它改成

String str = "{\"to\": \"" + token + "\", \"notification\": { \"body\": \"" +
    message + "\", \"badge\": \"1\"}}";
