Java invoke Sina Weibo API int64 type parameter incoming method __java

Sina Weibo data mining recently, need to call the Sina Weibo API, which requires the incoming user ID, that is, UID, for the int64 type.

source_id

False

Int64

The UID of the source user.

And there is no int64 type in Java, it's natural to start with long, because the range is not enough with Int.

Long uid = 2479449007l; or long uid = 2479449007;

Invokes the UID as a parameter to the API, resulting in an error

{"Error": "Parameter (source_id) ' s value invalid,expect (long), but get (2.479449007E9), and the doc for more info.", "error_cod E ": 10017," request ":"/2/friendships/show.json "}

You can see that Java automatically uses the UID notation in scientific notation.

How to not let it automatically converted into scientific counting method, toss for a long time, has not been able to ruyi.

At last I tried to pass the string directly,

String uid = "2479449007";

It seems that this API document, although it says you want to pass in the int64, can be passed in directly to the string.

BTW

If you read a string as a parameter modulation API in text file (TXT) form, the encoding format is ansi,utf-8 and the following error will be reported.

{"Error": "Parameter" (source_id) ' s value invalid,expect (long), but get (1978506667), and the doc for more info. "," Error_code " : 10017, "request": "/2/friendships/show.json"} Sina Weibo is so proud ....
