现在AFNetworking请求是很方便的。不过最近在做一个SDK。其实在sdk里用第三方库也是很正常的。比如极光的SDK就用了AF。只要告诉别人就行。避免重复引入。
不过这样也有一个问题，比如你用了2.0的版本。别人用了3.0的版本。这种情况其实很有可能发生，因为通常别人项目用的库是比较新的，而别人引入的一堆SDK，可能很久都不更新了。
假如3.0版本中把2.0的一个方法去掉了。这样sdk就报错了。虽然通常是会兼容，但也不排除。所以我在我的SDK里没有用到第三方库。都是用的ios原生网路请求。大部分用框架后，很多原生的东西就不再记得了。记录下：
1.先来看post请求：
//获取验证码 post ok
- (void)getSmsCodeWithPhone:(NSString *) phone{
//1.确定请求路径
NSString *apiUrl = [WkUtils getSmsCodeUrl];
NSLog(@"获取验证码的Url路径是： %@,传递的参数phone= %@",apiUrl,phone);
NSURL *url = [NSURL URLWithString:apiUrl];
//2.创建请求对象
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
//2.1更改请求方法
request.HTTPMethod = @"POST";
//2.2设置请求体
NSString *bodyStr = [NSString stringWithFormat:@"type=1&phone=%@",phone];
request.HTTPBody = [bodyStr dataUsingEncoding:NSUTF8StringEncoding];
//2.3请求超时
request.timeoutInterval = 10;
NSURLSession *session_post = [NSURLSession sharedSession];
NSURLSessionDataTask *task_post = [session_post dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if(error == nil) {
//说明:（此处返回的数据是JSON格式的，因此使用NSJSONSerialization进行反序列化处理）
//解析数据
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
NSLog(@"获取验证码服务端返回： %@",dic);
int code = [[dic objectForKey:@"code"] intValue];
if(code == 200){
} else {
NSString *msg = [WkUtils getServercCodeStr:code];
NSLog(@"验证码msg is %@",msg);
[self showMyAlertWithContent:msg];
}
}else{
NSLog(@"出错");
[self showMyAlertWithContent:@"获取验证码出错"];
}
}];
[task_post resume];
}
另外一个就是上传文件的，包括上传图片，这个功能经常用到，比如换头像什么的。
- (void)originalUploadFileWithImgName:(NSString *)imgName andImgData:(NSData *)imgData{
NSDictionary *params = @{@"address" : @"xxxx",
@"userName" : @"FlyElephant"};
// NSString *path = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"jpg"];
NSString *boundary = [self generateBoundaryString];
// 请求的Url
NSString *apiUrl = [WkUtils getUploadPicUrl];
NSLog(@"上传统头像Url路径是： %@",apiUrl);
NSURL *url = [NSURL URLWithString:apiUrl];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod:@"POST"];
// 设置ContentType
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request setValue:contentType forHTTPHeaderField: @"Content-Type"];
// NSString *fieldName = [@"CustomFile"];
NSData *httpBody = [self createBodyWithBoundary:boundary parameters:params imgName:imgName andImgData:imgData];
NSURLSessionTask *task = [[NSURLSession sharedSession] uploadTaskWithRequest:request fromData:httpBody completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if (error) {
NSLog(@"error = %@", error);
return;
}
//解析数据
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
NSLog(@"上传文件，服务端返回： %@",dic);
NSString *msg = [dic objectForKey:@"msg"] ;
int code = [[dic objectForKey:@"code"] intValue];
if(code == 200){
self.picUrl = [dic objectForKey:@"data"];
NSLog(@"picUrl is %@",self.picUrl);
} else {
NSLog(@"msg is %@",msg);
}
}];
[task resume];
}
- (NSData *)createBodyWithBoundary:(NSString *)boundary
parameters:(NSDictionary *)parameters
imgName:(NSString *)imgName
andImgData:(NSData *) imgData{
NSMutableData *httpBody = [NSMutableData data];
// 文本参数
[parameters enumerateKeysAndObjectsUsingBlock:^(NSString *parameterKey, NSString *parameterValue, BOOL *stop) {
[httpBody appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[httpBody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", parameterKey] dataUsingEncoding:NSUTF8StringEncoding]];
[httpBody appendData:[[NSString stringWithFormat:@"%@\r\n", parameterValue] dataUsingEncoding:NSUTF8StringEncoding]];
}];
[httpBody appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[httpBody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"%@\"\r\n", @"file", imgName] dataUsingEncoding:NSUTF8StringEncoding]];
[httpBody appendData:[[NSString stringWithFormat:@"Content-Type: %@\r\n\r\n", @"multipart/form-data"] dataUsingEncoding:NSUTF8StringEncoding]];
// [httpBody appendFormat:@"Content-Type: application/octet-stream\r\n\r\n"];
[httpBody appendData:imgData];
[httpBody appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[httpBody appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
return httpBody;
}
- (NSString *)generateBoundaryString {
return [NSString stringWithFormat:@"Boundary-%@", [[NSUUID UUID] UUIDString]];
}
是不是很麻烦，其实这些用afnetworking几句代码就可以搞定，哈哈哈。httpbody里面的那些具体数据就不说了，大家可以搜下iOS图片上传，网上有说，重要的就是\r\n代表换行
