app需要修改3個地方

1.manager.responseSerializer.acceptableContentTypes =nil;

2.修改AFNetworkReachabilityManager.m檔案，用下面函式替換原來的函式

+ (instancetype)manager {
    double version = [[UIDevice currentDevice].systemVersion doubleValue];
    if (version >= 9.0f) {
        struct sockaddr_in6 address; bzero(&address, sizeof(address));
        address.sin6_len = sizeof(address);
        address.sin6_family = AF_INET6;
        return [self managerForAddress:&address];
    } else {
#if (defined(__IPHONE_OS_VERSION_MIN_REQUIRED) && __IPHONE_OS_VERSION_MIN_REQUIRED >= 90000) || (defined(__MAC_OS_X_VERSION_MIN_REQUIRED) && __MAC_OS_X_VERSION_MIN_REQUIRED >= 101100)
        struct sockaddr_in6 address;
        bzero(&address, sizeof(address));
        address.sin6_len = sizeof(address);
        address.sin6_family = AF_INET6;
#else
        struct sockaddr_in address;
        bzero(&address, sizeof(address));
        address.sin_len = sizeof(address);
        address.sin_family = AF_INET;
#endif
        return [self managerForAddress:&address];
    }
}
 

3.網路請求程式碼這樣寫

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer.acceptableContentTypes = nil;//[NSSet setWithObject:@"text/ plain"];
manager.securityPolicy = [AFSecurityPolicy defaultPolicy];
manager.securityPolicy.allowInvalidCertificates = YES;//忽略https證書
manager.securityPolicy.validatesDomainName = NO;//是否驗證域名
