由于所有信息是以“UTF-8”的形式，進行上傳。
所以“POST請求”配置 ：[manager.requestSerializer setValue:@"application/x-www-form-urlencoded;charset=utf8" forHTTPHeaderField:@"Content-Type"];
base64加密（GTM三方庫）
/** GTM 轉碼 */
-(NSString *)base64Code {
//使用UTF-8方式轉碼
NSData * data = [self dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
data = [GTMBase64 encodeData:data];
NSString * output = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
// NSLog(@"%@",output);
return output;
}
NSDictionary * elementDict =
@{@"token":[User_Def objectForKey:@"token"]?[User_Def objectForKey:@"token"]:@"",//token
@"title":_titleTF.text,//標題
@"content":_detailTV.text,//內容
@"startDate":startDateStr,//開始日期
@"endDate":endDateStr,//結束日期
};
//使用YYModel，獲得字典的json字符串
NSString * elementStr = [NSString dictionaryToJson:elementDict];
//base64加密
NSString * base64ElementStr = [elementStr base64Code];
//拼接好URL字符串
NSString * urlStr = [NSString stringWithFormat:@"%@%@%@%@",Url_Header,CreateIdeaUrl,DataCodeUrl,base64ElementStr];
//需要以“UTF-8”編碼格式，進行請求
urlStr = [urlStr stringByAddingPercentEncodingWithAllowedCharacters: [NSCharacterSet characterSetWithCharactersInString:urlStr]];
//單例類 網請
[NetRequest_Shared POSTChineseUrl:urlStr parameters:nil success:^(id _Nullable responseObject) {
NSLog(@"%@",responseObject);
} failure:^(NSError * _Nonnull error) {
NSLog(@"%@",error);
NSLog (@"operation: %@",[error localizedDescription] );
} ];
網絡請求單例類：NetRequest
“NetRequest.h”文件：
//單例宏
#define NetRequest_Shared [NetRequest sharedNetRequest]
//POST中文
-(void)POSTChineseUrl:(NSString *)url parameters:(NSDictionary *)parameters success:(void (^)(id))success failure:(void (^)(NSError *))failure; //POST中文
//單例
+ (id)sharedNetRequest {
static NetRequest * netRequest = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
netRequest = [[NetRequest alloc] initSingleton];
});
return netRequest;
}
- (instancetype)initSingleton {
if (self = [super init]) {
}
return self;
}
//POST中文
-(void)POSTUrl:(NSString *)url parameters:(NSDictionary *)parameters success:(void (^)(id))success failure:(void (^)(NSError *))failure {
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeNone]; //表示不做SSL pinning
NSStringEncoding enc = CFStringConvertEncodingToNSStringEncoding (kCFStringEncodingGB_18030_2000);
manager.requestSerializer.stringEncoding = enc;//UTF8
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:@"application/x-www-form-urlencoded;charset=utf8" forHTTPHeaderField:@"Content-Type"];//UTF8類型
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/html",@"text/json",@"text/javascript",@"text/html", @"text/plain", nil];
manager.requestSerializer.timeoutInterval = 6; //請求超時
[manager POST:url parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
if (success) {
success(responseObject);
}
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
if (failure) {
failure(error);
}
}];
}
以上方式使用時，經常會報如下兩種錯誤：
1.“
Unterminated string at character 227 of of {\n \"token\" : \"eyJhc…………………………………………………………”
一般：//標點符號2.“
Expected a ',' or '}' at character 199 of {\n \"token\" : \"eyJhc…………………………………………………………”
一般：//漢字
別人說法是：json數據格式問題
例子：
"Expected a ',' or '}' at character 211 of {\n \"token\" : \"…………………………………………………………\",\n \"IdeaId\" : \"29cbffc82ef54f91b004f72a421d2714\",\n \"content\" : \"g\Ufffd\Ufffd#\Ufffd\Ufffd\U07e6\Ufffd;\Ufffd\U2dd6\Ufffd?\Ufffd\Ufffdc\Ufffd?\v\Ufffd\"C\Ufffd?\v\Ufffd\Ufffd;\UfffdV?\Ufffd\Ufffdm\U064c\Ufffd)\Ufffd"; }
一般是自己轉換的json字符串，包含了“\n”字符串
解決方案：
NSString * elementStr = [NSString dictionaryToJson:elementDict]; //“\n”改成下滑線“” elementStr = [elementStr stringByReplacingOccurrencesOfString:@"\n" withString:@""];NSString * elementStr = [elementDict yy_modelToJSONString]; //json相連（數據）
自己試了很久，沒用！
原因：在沒加密之前處理字符串，是沒用的！(使用YYModel轉換的json字符串是標準的)而應該處理：base64加密后的字符串。
解決辦法：把 不規則的base64字符，修改成規則
//不規則的base64字符修改成規則
base64ElementStr = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,\
(CFStringRef)base64ElementStr,NULL,CFSTR("!*'();:@&=+$,/?%#[]"),kCFStringEncodingUTF8));
最終 網請操作：
NSDictionary * elementDict =
@{@"token":[User_Def objectForKey:@"token"]?[User_Def objectForKey:@"token"]:@"",//token
@"title":_titleTF.text,//題目
@"content":_detailTV.text,//內容
@"startDate":startDateStr,//開始日期
@"endDate":endDateStr,//結束日期
};
//使用YYModel，獲得字典的json字符串
NSString * elementStr = [NSString dictionaryToJson:elementDict];
//base64加密
NSString * base64ElementStr = [elementStr base64Code];
//??????不規則的base64字符修改成規則??????
base64ElementStr = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,\
(CFStringRef)base64ElementStr,NULL,CFSTR("!*'();:@&=+$,/?%#[]"),kCFStringEncodingUTF8));
//拼接好URL字符串
NSString * urlStr = [NSString stringWithFormat:@"%@%@%@%@",Url_Header,CreateIdeaUrl,DataCodeUrl,base64ElementStr];
//需要以“UTF-8”編碼格式，進行請求
urlStr = [urlStr stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet characterSetWithCharactersInString:urlStr]];
//單例類 網請
[NetRequest_Shared POSTChineseUrl:urlStr parameters:nil success:^(id _Nullable responseObject) {
NSLog(@"%@",responseObject);
} failure:^(NSError * _Nonnull error) {
NSLog(@"%@",error);
NSLog (@"operation: %@",[error localizedDescription] );
} ];
就這鬼問題，搞了很多天！還好項目不趕，找問題找好久！
網請步驟：數據字典 —— json字符串 —— base64加密 —— 拼接為URL —— Post請求
出錯的地方在于使用了(三方庫)GTMBase64進行base64加密后，忘記處理 base64轉碼后的不規則字符！！
還一直以為是json格式問題！??????????????
