暴風(fēng) 上傳第一步
JSON （字典） 轉(zhuǎn) NSString ,
有序列化凭迹， 有 轉(zhuǎn)義字符忙芒，
然后base64 編碼
// 需要對(duì)這些參數(shù)進(jìn)行JSON編碼，寫(xiě)成JSON串的格式踏幻，則：
NSDictionary * dataDict = @{@"uptype":@0,@"servicetype":@1,@"filename":@"test.mp4",@"filekey":@"tom",@"filesize":@12489665,@"filetype":@0,@"deadline":@1451491200,@"callbackurl":@"http://mycompany.com" };
NSError *parseError = nil;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dataDict
options:NSJSONWritingPrettyPrinted
error:&parseError];
NSString * sttt = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
> 中間數(shù)據(jù)
> sttt __NSCFString * @"{\n \"uptype\" : 0,\n \"filesize\" : 12489665,\n \"filetype\" : 0,\n \"filekey\" : \"tom\",\n \"deadline\" : 1479874368,\n \"callbackurl\" : \"http:\\/\\/mycompany.com\",\n \"filename\" : \"test.mp4\",\n \"servicetype\" : 1\n}" 0x00006000001b5b60
NSString * baseStr = [[sttt dataUsingEncoding: NSUTF8StringEncoding] base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
??
??
NSString * strrrrr = @"{"uptype":0,"servicetype":1,"filename":"test.mp4","filekey":"tom", "filesize":12489665,"filetype":0,"deadline":1451491200, "callbackurl":"http://mycompany.com"}";
// 從安卓 那里 要過(guò)來(lái)的
NSString * baseStr = [[strrrrr dataUsingEncoding: NSUTF8StringEncoding] base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
結(jié)果：
baseStr __NSCFString * @"eyJ1cHR5cGUiOjAsInNlcnZpY2V0eXBlIjoxLCJmaWxlbmFtZSI6InRlc3QubXA0\r\nIiwiZmlsZWtleSI6InRvbSIsICJmaWxlc2l6ZSI6MTI0ODk2NjUsImZpbGV0eXBl\r\nIjowLCJkZWFkbGluZSI6MTQ1MTQ5MTIwMCwgImNhbGxiYWNrdXJsIjoiaHR0cDov\r\nL215Y29tcGFueS5jb20ifQ==" 0x000060000025ab20
