我使用AFHTTPRequestOperationManager将一些
JSON发布到我的服务器,我的代码如下.
NSDictionary *parameters = [[NSDictionary alloc] initWithObjectsAndKeys:@"john",@"name",@"xxxxx@gmail.com",@"email",@"xxxx",@"password",@"1",@"type",nil];
// Do any additional setup after loading the view.
AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
[policy setAllowInvalidCertificates:YES];
AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
[operationManager setSecurityPolicy:policy];
[operationManager POST:@"posturl here" parameters:parameters success:^(AFHTTPRequestOperation *operation,id responSEObject) {
NSLog(@"JSON: %@",[responSEObject description]);
} failure:^(AFHTTPRequestOperation *operation,NSError *error) {
NSLog(@"Error: %@",[error description]);
}];
答复如下：

我不知道这是什么问题.
解决方法
在执行您的请求之前,需要使用AFJSONRequestSerializer和AFJSONResponseSerializer设置请求和响应序列化程序来处理JSON.为您的参数使用NSDictionary文字帮助代码清晰度：
AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
[policy setAllowInvalidCertificates:YES];
AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
[operationManager setSecurityPolicy:policy];
operationManager.requestSerializer = [AFJSONRequestSerializer serializer];
operationManager.responseSerializer = [AFJSONResponseSerializer serializer];
[operationManager POST:@"posturl here"
parameters: @{@"name": @"john",@"email": @"xxxxx@gmail.com",@"password: @"xxxxx",@"type": @"1"}
success:^(AFHTTPRequestOperation *operation,id responSEObject) {
NSLog(@"JSON: %@",[responSEObject description]);
}
failure:^(AFHTTPRequestOperation *operation,NSError *error) {
NSLog(@"Error: %@",[error description]);
}
];
