當我們向后臺請求得到一個html網(wǎng)頁時竖独，后臺返回的數(shù)據(jù)如下：

此時 我們會發(fā)現(xiàn)發(fā)生了錯誤
這是因為 AFNetworking默認把響應(yīng)結(jié)果當成json來處理,(默認manager.responseSerializer = [AFJSONResponseSerializer serializer]) ,很顯然,我們請求的 返回的并不是一個json文本,而是一個html網(wǎng)頁,但是AFNetworking并不知道,它堅信請求的結(jié)果就是一個json文本!然后固執(zhí)地以json的形式去解析,顯然沒辦法把一個網(wǎng)頁解析成一個字典或者數(shù)組,所以產(chǎn)生了上述錯誤.
然而,我們期望它能夠正確地處理這個情形,而不是提示一個錯誤.
這時候 你必須告訴AFNetworking:別把這個網(wǎng)頁當json來處理!
此時需要設(shè)置一下參數(shù)驯击，代碼如下：
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json",@"text/json",@"text/javascript",@"text/html",@"text/plain",nil];
[manager POST:@"http://192.168.1.133:8087/hxxentry_shop/shop/course/getCourseDetailHtml" parameters: parameter progress:^(NSProgress * _Nonnull uploadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSString *result = [[NSString alloc]initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(@"%@",result);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"%@",error);
}];
此時便可得到一個字符串，這個字符串里就是我們要的html數(shù)據(jù)
通過webview展示即可：
[_webView loadHTMLString:htmlStr baseURL:nil];
