由于所有信息是以“UTF-8”的形式，进行上传。
所以“POST请求”配置 ：[manager.requestSerializer setValue:@"application/x-www-form-urlencoded;charset=utf8" forHTTPHeaderField:@"Content-Type"];
base64加密（GTM三方库）
/** GTM 转码 */
-(NSString *)base64Code {
//使用UTF-8方式转码
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,//标题
@"content":_detailTV.text,//内容
@"startDate":startDateStr,//开始日期
@"endDate":endDateStr,//结束日期
};
//使用YYModel，获得字典的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”编码格式，进行请求
urlStr = [urlStr stringByAddingPercentEncodingWithAllowedCharacters: [NSCharacterSet characterSetWithCharactersInString:urlStr]];
//单例类 网请
[NetRequest_Shared POSTChineseUrl:urlStr parameters:nil success:^(id _Nullable responseObject) {
NSLog(@"%@",responseObject);
} failure:^(NSError * _Nonnull error) {
NSLog(@"%@",error);
NSLog (@"operation: %@",[error localizedDescription] );
} ];
网络请求单例类：NetRequest
“NetRequest.h”文件：
//单例宏
#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
//单例
+ (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类型
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; //请求超时
[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);
}
}];
}
以上方式使用时，经常会报如下两种错误：
1.“
Unterminated string at character 227 of of {\n \"token\" : \"eyJhc…………………………………………………………”
一般：//标点符号2.“
Expected a ',' or '}' at character 199 of {\n \"token\" : \"eyJhc…………………………………………………………”
一般：//汉字
别人说法是：json数据格式问题
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"; }
一般是自己转换的json字符串，包含了“\n”字符串
解决方案：
NSString * elementStr = [NSString dictionaryToJson:elementDict]; //“\n”改成下滑线“” elementStr = [elementStr stringByReplacingOccurrencesOfString:@"\n" withString:@""];NSString * elementStr = [elementDict yy_modelToJSONString]; //json相连（数据）
自己试了很久，没用！
原因：在没加密之前处理字符串，是没用的！(使用YYModel转换的json字符串是标准的)而应该处理：base64加密后的字符串。
解决办法：把 不规则的base64字符，修改成规则
//不规则的base64字符修改成规则
base64ElementStr = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,\
(CFStringRef)base64ElementStr,NULL,CFSTR("!*'();:@&=+$,/?%#[]"),kCFStringEncodingUTF8));
最终 网请操作：
NSDictionary * elementDict =
@{@"token":[User_Def objectForKey:@"token"]?[User_Def objectForKey:@"token"]:@"",//token
@"title":_titleTF.text,//题目
@"content":_detailTV.text,//内容
@"startDate":startDateStr,//开始日期
@"endDate":endDateStr,//结束日期
};
//使用YYModel，获得字典的json字符串
NSString * elementStr = [NSString dictionaryToJson:elementDict];
//base64加密
NSString * base64ElementStr = [elementStr base64Code];
//⭐️⭐️⭐️不规则的base64字符修改成规则⭐️⭐️⭐️
base64ElementStr = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,\
(CFStringRef)base64ElementStr,NULL,CFSTR("!*'();:@&=+$,/?%#[]"),kCFStringEncodingUTF8));
//拼接好URL字符串
NSString * urlStr = [NSString stringWithFormat:@"%@%@%@%@",Url_Header,CreateIdeaUrl,DataCodeUrl,base64ElementStr];
//需要以“UTF-8”编码格式，进行请求
urlStr = [urlStr stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet characterSetWithCharactersInString:urlStr]];
//单例类 网请
[NetRequest_Shared POSTChineseUrl:urlStr parameters:nil success:^(id _Nullable responseObject) {
NSLog(@"%@",responseObject);
} failure:^(NSError * _Nonnull error) {
NSLog(@"%@",error);
NSLog (@"operation: %@",[error localizedDescription] );
} ];
就这鬼问题，搞了很多天！还好项目不赶，找问题找好久！
网请步骤：数据字典 —— json字符串 —— base64加密 —— 拼接为URL —— Post请求
出错的地方在于使用了(三方库)GTMBase64进行base64加密后，忘记处理 base64转码后的不规则字符！！
还一直以为是json格式问题！😂😂😂😂😂😂😂
