IOS开发小记

1.对服务器进行Https请求

-服务器：获取证书后需提供文件***.pem文件给IOS开发

-IOS开发：将得到的pem文件双击加入钥匙串后导出一份cer

-项目：将对应的cer文件放置在文件中，并在网络请求的方法中添加以下代码

+ (AFSecurityPolicy *)customSecurityPolicy{

    NSString * cerPath = [[NSBundle mainBundle] pathForResource:@"www.yqb168.com" ofType:@"cer"];

    NSData * cerData = [NSData dataWithContentsOfFile:cerPath];

    NSSet * cerSet = [NSSet setWithObjects:cerData, nil];

    AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];

    // 是否验证域名

    securityPolicy.validatesDomainName = YES;

    // 信任非法证书（自签名证书）

    securityPolicy.allowInvalidCertificates = NO;

    // 设置证书

    [securityPolicy setPinnedCertificates:cerSet];

    return securityPolicy;

}

2.数据请求报错：The data couldn’t be read because it isn’t in the correct format.

-问题1：后台返回数据格式有误；

-问题2：app请求参数数据序列化的格式（requestSerializer）不正确；

-问题3：其他。

后台及其他问题暂不考虑，IOS app端更改requestSerializer设置：AFHTTPRequestSerializer/AFJSONRequestSerializer

+ (AFHTTPSessionManager *)apiRequest:(AFHTTPRequestSerializer *)serializer{

    serializer = [AFJSONRequestSerializer serializer];

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

    AFSecurityPolicy *securityPolicy = [self customSecurityPolicy]; //https设置，http可直接alloc后使用

    [manager setSecurityPolicy:securityPolicy];

    [manager.responseSerializer setAcceptableContentTypes:[NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html",@"text/plain", nil]];

manager.responseSerializer.acceptableContentTypes=[manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];//Very Important

    serializer.timeoutInterval = 40.f;

    manager.requestSerializer = serializer;

    return manager;

}
