JSON （字典） 转 NSString ,
有序列化， 有 转义字符，
然后base64 编码
// 需要对这些参数进行JSON编码，写成JSON串的格式，则：
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];
> 中间数据
> 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"}";
// 从安卓 那里 要过来的
NSString * baseStr = [[strrrrr dataUsingEncoding: NSUTF8StringEncoding] base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
结果：
baseStr __NSCFString * @"eyJ1cHR5cGUiOjAsInNlcnZpY2V0eXBlIjoxLCJmaWxlbmFtZSI6InRlc3QubXA0\r\nIiwiZmlsZWtleSI6InRvbSIsICJmaWxlc2l6ZSI6MTI0ODk2NjUsImZpbGV0eXBl\r\nIjowLCJkZWFkbGluZSI6MTQ1MTQ5MTIwMCwgImNhbGxiYWNrdXJsIjoiaHR0cDov\r\nL215Y29tcGFueS5jb20ifQ==" 0x000060000025ab20
